12:02 AM lcnc-relay: <captainhindsight_.> pcw---home: does the AMD EOL of many Spartan devices also EOL some of your earlier boards?
12:16 AM pcw---home: Spartan 2 and 3 stuff yes but we have not made those for years
12:43 AM mrec: I need to get some digital communication set up with the 7i96s rs422, with periodic data frames
12:44 AM mrec: I guess until September everything will just be based on theory, afterwards I can debug the system properly since I'm going to leave Taiwan for a month and the Mitsubishi CNC machine I'm working on is here
12:45 AM mrec: the protocol is mostly clear
12:46 AM roycroft: labour just hit 400 seats, with 38 still to be decided
01:40 AM Deejay: moin
02:21 AM -!- #linuxcnc mode set to +v by ChanServ
10:39 AM rdtsc_away is now known as rdtsc
11:12 AM lcnc-relay: <ffffrf> Thank you. - I am making incremental progress on setting up the mesa board with my sherline lathe but now am encountering two issues. I am getting my Z axis to move, however, it only moves in one direction, it either does nothing when jogging the other way, or continues to go backwards
11:12 AM lcnc-relay: <ffffrf> inverting the signal just flips the issue but does not resolve it
11:15 AM Tom_L: is there a direction pin?
11:15 AM lcnc-relay: <ffffrf> This is the pinout from sherline's driver box: sherline parallel port pinout:
11:15 AM lcnc-relay: Pin 1: estop out
11:15 AM lcnc-relay: Pin 2: X direction
11:15 AM lcnc-relay: Pin 3: X step
11:15 AM lcnc-relay: Pin 4: Y direction
11:15 AM lcnc-relay: Pin 5: Y step
11:15 AM lcnc-relay: Pin 6: Z direction
11:15 AM lcnc-relay: Pin 7: Z step
11:16 AM lcnc-relay: Pin 8: A direction
11:16 AM lcnc-relay: Pin 9: A step
11:16 AM lcnc-relay: Pin 14: spindle cw (clockwise)
11:16 AM lcnc-relay: Pin 16: spindle pwm (pulse-width modulation)
11:16 AM lcnc-relay: Pin 17: amplifier enable
11:16 AM lcnc-relay: Pins 10, 11, 12, 13, 15: not used
11:16 AM lcnc-relay: <ffffrf> I connected
11:16 AM Tom_L: paste.debian.net is your friend
11:16 AM Tom_L: and ours
11:17 AM lcnc-relay: <ffffrf> I connected the Zstep pin from sherline to step+ and likewise direction pin to dir+ and then connected ground from the parallel port to dir- and step-
11:17 AM Tom_L: use hal show to watch the direction pins
11:18 AM pcw---home: OWW!
11:18 AM lcnc-relay: <ffffrf> like during axis testing?
11:18 AM Tom_L: of course
11:19 AM pcw---home: connect ground to ground DO NOT CONNECT STEP- or DIR-
11:20 AM lcnc-relay: <ffffrf> so leave the step- pin on the mesa unconnected and instead connect the ground pin to gnd?
11:20 AM pcw---home: Yes
11:22 AM pcw---home: You are shorting out the (unused) DIR-/STEP- pins and you do no have a valid ground
11:22 AM JT-Shop: yikes
11:22 AM lcnc-relay: <ffffrf> I do also have a ground wire from the driver box connected to general gnd though
11:22 AM Tom_L: woops
11:22 AM lcnc-relay: <ffffrf> or is that still bad
11:22 AM lcnc-relay: <ffffrf> 😛
11:26 AM pcw---home: worse
11:27 AM lcnc-relay: <ffffrf> 🤣
11:28 AM pcw---home: 7I96S step/dir connector GND --> interface GND 7I96S STEP+/DIR+ to interface STEP/DIR
11:28 AM pcw---home: 7I96S STEP-/DIR- unconnected
11:29 AM pcw---home: STEP-/DIR- are only used for differential signaling (like many servo drives)
11:29 AM lcnc-relay: <ffffrf> mannnn
11:32 AM -!- #linuxcnc mode set to +v by ChanServ
11:33 AM lcnc-relay: <ffffrf> ok so after that change
11:34 AM lcnc-relay: <ffffrf> the Z axis still only moves one direction, however, both the forward and backwards jog generate smooth movement
11:34 AM lcnc-relay: <ffffrf> as opposed to one direction cause nothing or strange behavior
11:34 AM lcnc-relay: <ffffrf> so something to do with direction change
11:35 AM Tom_L: use hal show to watch the direction pins
11:36 AM Tom_L: http://linuxcnc.org/docs/stable/html/hal/tools.html#_halshow
11:36 AM pcw---home: I would check the Z direction pin voltage when jogging in either direction
11:36 AM Tom_L: may have cooked that one
11:37 AM * JT-Cave prepares to depart
11:37 AM Tom_L: wherefor do you depart to?
11:38 AM Tom_L: gonna break in that extra tranny oil?
11:41 AM lcnc-relay: <ffffrf> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/JNpylZqeLmAgpTVxdfHCxsKA/IMG_0055.jpg
11:41 AM lcnc-relay: <ffffrf> it just stays at zero does not change when i jog in positive or negative
11:41 AM lcnc-relay: <ffffrf> maybe i should try reconnecting the wires properly to a different stepper driver pin set on the board?
11:42 AM pcw---home: try at the 7I96S pins with the connector removed
11:43 AM lcnc-relay: <ffffrf> sorry could you elaborate on what that means? like remove the wires off of the mesa stepper section and try jogging it alone to watch pin changes?
11:47 AM pcw---home: You unplug the Z (stepgen 2?) connector on the 7I96S and measure the dir+ pin
11:50 AM lcnc-relay: <ffffrf> with a multimeter correct?
11:59 AM pcw---home: Yes
12:01 PM lcnc-relay: <ffffrf> no changes
12:01 PM lcnc-relay: <ffffrf> when jogging +/-
12:01 PM lcnc-relay: <ffffrf> so guess i fried pin?
12:02 PM lcnc-relay: <ffffrf> checking the step pin shows it working as expected
12:03 PM lcnc-relay: <ffffrf> actually wait when i jog in + direction it does get to 4.6V
12:03 PM lcnc-relay: <ffffrf> the dir pin
12:04 PM lcnc-relay: <ffffrf> going from negative to positive jogging causes 5v on the dir pin going from positve to negative stays at 0v
12:09 PM lcnc-relay: <ffffrf> so it esentially only goes to 5v when i jog+
12:11 PM lcnc-relay: <ffffrf> damn it so that means its working correctly and its something downstream with the driver box I think
12:15 PM lcnc-relay: <ffffrf> but its wierd because halmeter or halshow does not show the dir to change when jogging
12:25 PM lcnc-relay: <ffffrf> wtf in halmeter it doesnt show the specific stepgen direction pin
12:25 PM lcnc-relay: <ffffrf> ugh
12:48 PM pcw---home: You would need to know the GPIO pin (stepgen 02 dir is GPIO 22 for example)
12:50 PM pcw---home: when LinuxCNC starts (if launched from a terminal window) it lists this:
12:50 PM pcw---home: hm2/hm2_7i96s.0: IO Pin 021 (TB1-14/TB1-15): StepGen #2, pin Step (Output)
12:50 PM pcw---home: hm2/hm2_7i96s.0: IO Pin 022 (TB1-16/TB1-17): StepGen #2, pin Direction (Output)
12:50 PM pcw---home: h
12:55 PM lcnc-relay: <ffffrf> okay, my pin is io20, thank you let me retry halshow
12:56 PM lcnc-relay: <ffffrf> for stepgen 1
12:57 PM lcnc-relay: <ffffrf> okay yes halmeter shows it working
12:57 PM lcnc-relay: <ffffrf> I guess this confirms its downstream of the mesa board, right? Which sucks because it will be much harder to fix lol
01:02 PM lcnc-relay: <ffffrf> I had the driver box working correctly in linux 2.7 so i dont think something is broken with the driver box
01:11 PM pcw---home: Check that the dir pin (measured with a voltmeter) still changes from ~0V to ~5V when connected to the interface
01:12 PM pcw---home: if not, there may be a wiring error or the interface may have been damaged by the incorrect connections
01:13 PM pcw---home: Connecting the step-/dir- pins to the interface GND if the interface GND was not connected to 7I96S GND
01:14 PM pcw---home: would apply ~-5V to the inputs
01:20 PM rdtsc is now known as rdtsc_away
01:22 PM rdtsc_away is now known as rdtsc
01:25 PM lcnc-relay: <ffffrf> when the dir pin is connected to sherline, it still does the voltage changes x_x
01:29 PM lcnc-relay: <ffffrf> I might reinstall linuxcnc 2.7 and redo everything with sherline driver box alone since I know it worked last time, guess that may show if the driver box is bad
01:30 PM pcw---home: If the voltage changes and the direction does not, that points to a problem in the interface
01:31 PM Tom_L: no real need to reinstall everything to find that out
01:31 PM pcw---home: (you could verify by disconnecting the Z direction pin from the 7I96S and jogging with it tied to 5V or GND)
01:32 PM pcw---home: if that does not change direction, there is an interface or wiring error
01:49 PM lcnc-relay: <ffffrf> yah looks like it is the interface, damn it i feel like i need to just start over and get steppers with integrated drivers and wire to mesa and bypass sherlibe stuff
01:53 PM Tom_L: sounds like a decent plan
02:20 PM rdtsc: Just had to glue two 2x4x8's together to make a "4"x4 because local place only had them in treated variety... need untreated. Making six carpenter bee traps
02:31 PM lcnc-relay: <ffffrf> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/DMKGYQyuCQlQsCVxjzItwJRX/image.png
02:31 PM lcnc-relay: <ffffrf> Do yall think going with these would be enough to get myself running with the lathe? Not looking for anything fancy. Already got a power supply that will work. I really should have only gotten the sherline frame and not get scammed by their overpriced steppers / driver box lol
02:33 PM pcw---home: Those should be fine but you would also be able to use the original motors and 3 low cost drives
02:34 PM lcnc-relay: <ffffrf> so I was hoping to use the original motors but I am out of my depth on how to manually wire them, sherline has it written in a confusing way for me : https://sherline.com/wp-content/uploads/2018/08/hi-torque_stepper_spec.pdf?_ga=2.7158066.1216538925.1720201413-2027070277.1718319041
02:35 PM pcw---home: https://www.omc-stepperonline.com/digital-stepper-driver-1-0-4-2a-20-50vdc-for-nema-17-23-24-stepper-motor-dm542t
02:35 PM lcnc-relay: <ffffrf> I dont want to waste your time, I would really like to use the originals, they are branded as anaheim automation 23Y series steppers, when I go onto their website, the wire colors do not match for unipolar wiring like sherline has, and I am not sure how to determine how to wire the original steppers to a driver
02:36 PM lcnc-relay: <ffffrf> https://www.anaheimautomation.com/manuals/stepper/L010164%20-%2023Y%20Series%20Spec%20Sheet.pdf this is a similar version to the one I have (the exact one i have is not listed on their website)
02:38 PM pcw---home: Yeah those are awkward since they were used with a unipolar drive
02:39 PM lcnc-relay: <ffffrf> would that cheap driver work for a unipolar stepper?
02:39 PM pcw---home: if all 6 wires are brought out to the 5 pin connector, just cut and tape off the brown and green wires (individually)
02:40 PM roycroft: ffffr - maybe this will help: https://www.youtube.com/watch?v=FYYmuUJyPes
02:40 PM pcw---home: then you can use a bipolar step motor driver
02:40 PM roycroft: the video discusses deducing the wiring for both unipolar and bipolar motors
02:41 PM pcw---home: though you may want a higher power supply voltage since you are now using the windings in series
02:44 PM lcnc-relay: <ffffrf> hmmm okay , that driver is cheap enough its worth ordering and trying - the sherline documents say they need to connect some wires together into a single pin so i wonder if they aer actually using a bipolar driver as well? idk lol. I will watch the video
02:47 PM pcw---home: The motors can be either, but the common centertaps (green and brown) means unipolar mode
02:52 PM roycroft: https://www.youtube.com/watch?v=hHe4Fc6uuBs
02:52 PM roycroft: that one is better
02:53 PM roycroft: the first video just glosses over unipolar motors
02:53 PM roycroft: but the second one shows how to identiy the wires for them - they're using a 6 wire motor
02:56 PM roycroft: the second video has no narration and annoying "music", so i would mute it
02:57 PM lcnc-relay: <ffffrf> thank you
03:08 PM lcnc-relay: <ffffrf> nvm i think it wont be feasible
03:08 PM lcnc-relay: <ffffrf> its a 4.5v stepper motor
03:08 PM lcnc-relay: <ffffrf> these drives all need higher voltage
03:11 PM lcnc-relay: <zincboy_ca_on> All (non trivial) stepper drives are current mode and you set the max winding current. The motor voltage only matters for very basic drives without current limit. It also gives you an idea of the inductance and how fast you can run the motor. You can run a "4.5V" motor on a 24 or 36V drive without issue as long as the current limit is set correctly.
03:29 PM lcnc-relay: <skunkworks8841> Yes.. the higher the voltage the better.. as with servos - voltage dictates max rpm - current is torque..
03:36 PM roycroft: mt st helens has been doing some rumbling recently
03:36 PM roycroft: not a lot, but a marked increase over average
03:37 PM roycroft: but the last two times it erupted, it did so after a gradual increase in rumbing, followed by a significant increase, and the eruptions happened a week after the significant increase
03:38 PM roycroft: so yeah, that might be something else to look forward to before too long
03:43 PM xxcoder: oh boy
03:44 PM xxcoder: in lest its not rainier. its basically rocks held together by mud, ice, trees and snow
03:44 PM xxcoder: if it ever goes off, lot of region around it gets taken out by mud, including tacoma
03:59 PM roycroft: yeah, rainier is less likely to erupt soon, but if it does, it will likely be 10x worse than anything mt st helens would do
03:59 PM roycroft: and, of course, "less likely" could change at any moment
04:00 PM roycroft: my cat is unhappy that the living room window is not open
04:01 PM roycroft: i don't know how to explain to her that she would be much more unhappy if it were
04:32 PM lcnc-relay: <skunkworks8841> oof - mosquitos are so bad right now...
04:32 PM lcnc-relay: <skunkworks8841> so bad that I might jus walk around with a chainsaw idling with me..
04:46 PM roycroft: we're about to be on chainsaw ban here
04:46 PM roycroft: well, after 10am
04:47 PM lcnc-relay: <skunkworks8841> 10am?
04:51 PM roycroft: when the fire danger is high chainsaws may not be used after 10am around here
04:51 PM roycroft: the fire danger was low as of yesterday, but it bet it will be high by the end of the weekend
05:03 PM -!- #linuxcnc mode set to +v by ChanServ
05:03 PM JT-Mobile: yo
05:11 PM lcnc-relay: <ffffrf> guys
05:11 PM lcnc-relay: <ffffrf> i just thought of something
05:11 PM lcnc-relay: <ffffrf> for my broken sherlibe driver box
05:11 PM lcnc-relay: <ffffrf> couldn’t i use the other two axis? Y and A??
05:12 PM lcnc-relay: <ffffrf> wired correctly?
05:12 PM lcnc-relay: <ffffrf> their dir pin shouldn’t be fried
05:12 PM lcnc-relay: <ffffrf> i’m gonna replace everything anyway but
05:22 PM JT-Mobile: should work
05:45 PM Tom_L: ok, trimmed a few low hanging branches and discarded them
05:46 PM Tom_L: after replacing the pole saw primer bulb
05:51 PM lcnc-relay: <ffffrf> before i turn stuff on, now that i have dir+ wired, step+ wired and the GND wired I now switched the wires to the y step and dir on the sherlibe driver box, that’s all i really need to do right? since I am not using a standard parallel port pinout and just wiring directly to the pins i need
05:52 PM Tom_L: sounds right
05:53 PM Tom_L: all the steppers the same size?
05:53 PM Tom_L: since that's not a chopper drive you may want to check that
05:54 PM Tom_L: in case there is a current setting
05:54 PM lcnc-relay: <ffffrf> sherline only sells one type of stepper
05:54 PM lcnc-relay: <ffffrf> so should be the same
05:54 PM Tom_L: should be good to go then
05:55 PM * Tom_L puts a helmet on
05:57 PM rdtsc is now known as rdtsc_away
05:58 PM lcnc-relay: <ffffrf> lol no axis movement, back to the drawing board, gonna power cycle everything first though
06:01 PM Tom_L: power supply didn't blow a fuse when you shorted direction did it?
06:01 PM lcnc-relay: <ffffrf> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/iYHxAnlvzLvAkExQshshYxIt/IMG_0061.jpg
06:01 PM lcnc-relay: <ffffrf> it has fuses on each axis, none were blown, didn’t see anything else out of the ordinary
06:02 PM lcnc-relay: <ffffrf> power supply itself is def working
06:03 PM Tom_L: none of the axis move?
06:03 PM lcnc-relay: <ffffrf> i only had Z working, and now that i switched to the y axis ports on the sherlibe box, it no longer moved
06:04 PM Tom_L: don't unplug them with the power on
06:04 PM Tom_L: that's another big no no
06:04 PM lcnc-relay: <ffffrf> oh i didn’t
06:04 PM lcnc-relay: <ffffrf> everything was off when i made the changes
06:07 PM Tom_L: you sure you moved the right wires on the parallel port?
06:08 PM lcnc-relay: <ffffrf> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/FCtTwwPsIiLAIYueKlkyXsBP/IMG_0063.jpg
06:08 PM lcnc-relay: <ffffrf> yep :/ went from 7,6 to 5,4
06:08 PM lcnc-relay: <ffffrf> maybe something is more broken with the driver than i thought but if z was still working on the z line in one direction that doesn’t make sense to me
06:09 PM lcnc-relay: <ffffrf> maybe i will switch back to Z and see if it still jogs one way
06:09 PM lcnc-relay: <ffffrf> after powering down
06:09 PM Tom_L: is A being used for anything?
06:09 PM lcnc-relay: <ffffrf> no
06:09 PM Tom_L: it would be the least likely to be damaged ehh?
06:09 PM lcnc-relay: <ffffrf> A is also free, but assuming i broke two of the axis - i need both A and Y to work
06:10 PM lcnc-relay: <ffffrf> Y axis was never used
06:10 PM lcnc-relay: <ffffrf> but maybe i just broke it too 🤣
06:10 PM lcnc-relay: <ffffrf> will have a 1 axis lathe
06:15 PM lcnc-relay: <ffffrf> nope now Z is not jogging so must be something else
06:16 PM lcnc-relay: <ffffrf> but i changed nothing besides the wires lol
06:16 PM lcnc-relay: <ffffrf> i guess i opened up the driver box too but i didn’t touch anything
06:19 PM lcnc-relay: <ffffrf> this time there is a red light on mesa so maybe it’s some other issue now guess i will poke around lol
06:19 PM JT-Mobile: Tom_L, putzing with the dark theme but the up/down arrows on spin boxes is borked
06:20 PM Tom_L: i may have had those working on mine i can't remember which boxes are which
06:20 PM Tom_L: i know i couldn't figure out the background for the tool change list when it's opened up
06:20 PM Tom_L: what is that? a combo box?
06:21 PM JT-Mobile: yup dhoulf nr a combo box
06:21 PM JT-Mobile: damn laptip keybord
06:21 PM Tom_L: also i don't recall the widget names but some weren't listed in your dark qss file but changed color
06:21 PM Tom_L: are they in groups?
06:22 PM JT-Mobile: a QWidget will affect all widgets
06:22 PM Tom_L: textedit maybe, i can't remember
06:22 PM Tom_L: oh
06:22 PM Tom_L: well no wonder
06:22 PM Tom_L: then under that are sub categories?
06:23 PM Tom_L: is there a reason you're using hex colors over rgb or rgba?
06:24 PM JT-Mobile: rgba can allow you to spec alpha or intensity other wise hex and rgb are the same
06:25 PM Tom_L: damn, i was going thru my pc and found an old new brittan gridley model 61 repair manual
06:25 PM Tom_L: 6 spindle
06:25 PM JT-Mobile: wtf is that?
06:25 PM Tom_L: an old cam drive 6 spindle lathe
06:25 PM Tom_L: automatic
06:25 PM Tom_L: i ran a row of those for a while along with an 8 spindle
06:25 PM JT-Mobile: nice
06:26 PM Tom_L: ww2 era
06:26 PM Tom_L: the 50 series is newer
06:26 PM Tom_L: 50 51 52
06:26 PM JT-Mobile: the most interesting machine I've ever seen was in Taiwan must have had over 100 cams
06:26 PM Tom_L: when it indexes, it lifts the whole carriage
06:26 PM Tom_L: for wear reasons
06:29 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/newbritain/
06:29 PM Tom_L: old tech there
06:30 PM JT-Mobile: looks busy
06:30 PM Tom_L: cross slide on each spindle
06:30 PM Tom_L: and 6 end positions for drills or whatever
06:31 PM Tom_L: some had spindle brakes for doing cross drilling etc
06:31 PM lcnc-relay: <ffffrf> wait
06:31 PM lcnc-relay: <ffffrf> i’m dumb
06:31 PM lcnc-relay: <ffffrf> i went back to z axis setup
06:32 PM lcnc-relay: <ffffrf> and it’s working again
06:32 PM lcnc-relay: <ffffrf> only one direction
06:32 PM lcnc-relay: <ffffrf> why the hell wouldn’t it work off the y axis plug on the box makes zero sense
06:32 PM Tom_L: maybe you have some wires crossed or the config isn't quite right
06:32 PM lcnc-relay: <ffffrf> identical motors and connectors
06:34 PM lcnc-relay: <ffffrf> i wonder if they disconnect the axis if you like order a lathe
06:34 PM lcnc-relay: <ffffrf> or like disable them somehow
06:36 PM Tom_L: talking about stepper voltate, mine are rated for 3.86V and my psu is 48v
06:38 PM lcnc-relay: <ffffrf> i bet they disable them or something i just tried A axis and it doesn’t work either
06:38 PM xxcoder: you probably would have to backtrace stuff see if every axis has everything or not
06:38 PM Tom_L: any missing parts on those on the board?
06:39 PM lcnc-relay: <ffffrf> not when i looked, they looked the same although i didn’t want to pry off the board to look at the underside - wish i could call them but their support hours are closed
06:41 PM JT-Mobile: one of the guys that will be with us tomorrow has a `20 GT500 and that's 760HP!
06:42 PM Tom_L: useable?
06:42 PM JT-Mobile: yup on the highway
06:42 PM Tom_L: you still gotta get that to the pavement
06:42 PM JT-Mobile: I will be able to lap him on the road course lol
06:42 PM Tom_L: sounds like you're having fun
06:43 PM JT-Mobile: I hope to
06:43 PM Tom_L: does rousch add their touches to that thing?
06:44 PM JT-Mobile: from a dig a C8 can beat them all up to a 1/4 mile
06:44 PM JT-Mobile: it's a shelby
06:44 PM Tom_L: https://www.roushperformance.com/products/2021-roush-stage-3-mustang
06:44 PM Tom_L: etc
06:45 PM Tom_L: aww that on is only 750hp
06:45 PM JT-Mobile: nephew has a roush mustang
06:46 PM JT-Mobile: none of those bad boys can put the power to the ground until they get some speed
06:47 PM Tom_L: i've never been overly impressed with mustang in general
06:47 PM Tom_L: they make alot of noise
06:48 PM Tom_L: far as that goes i think the camero can beat them hands down
06:53 PM JT-Mobile: I think they are pretty even but the camero looks a lot better
06:55 PM Tom_L: stick a small block from Hendrix in one and you'd have something
06:55 PM lcnc-relay: <zincboy_ca_on> Having been in both when driving in anger on the track, I would put the nod to the camero. At least in top line track trim.
06:55 PM JT-Mobile: track day tomorrow for me
06:56 PM Tom_L: i figured that was coming up since you 'tuned' up the tranny
06:56 PM Tom_L: did you ever get any track tires?
06:57 PM JT-Mobile: no, going with the AS Michelin tires
06:58 PM Tom_L: when the boys were younger we went thru the Hendrix shop amongst a couple others
06:58 PM JT-Mobile: the Misfit Toys Car Club only does this about 3 times a year so not worth buying summer only tires
06:58 PM lcnc-relay: <ffffrf> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/YPPmqVFrrwwwTUMCOGeSyfem/IMG_0064.jpg
06:58 PM lcnc-relay: <ffffrf> what if i tried switching the chips between Z and A x_x
06:58 PM Tom_L: they got a kick out of that for sure
06:59 PM JT-Mobile: if there was a place like Spring Mountain near by I'd have gotten a Z51
07:00 PM JT-Mobile: but for an hour of track time a few times a year a Stingray is a better choice
07:00 PM Tom_L: enough to keep the adrenaline goin
07:01 PM JT-Mobile: yup keeps the blood pumping for sure
07:02 PM JT-Mobile: wife asked me if I was nervous and I said nope... I have enough track time to not be nervous
07:02 PM Tom_L: i think my bud finally quit racing.. he's gotta be 80 now
07:03 PM JT-Mobile: and enough track time to be careful
07:04 PM JT-Mobile: this is not racing it's tracking... makes a difference in the warranty lol
07:04 PM Tom_L: i know the one with the alcohol funny car did but i think his kid still does it
07:04 PM Tom_L: oh absolutely!
07:04 PM JT-Mobile: interesting that alcohol has less energy than gas
07:05 PM Tom_L: keith black 540 aluminum block
07:05 PM Tom_L: blown
07:06 PM JT-Mobile: drag racing wait..... wait.... a few seconds and wait again
07:06 PM Tom_L: yeah that part is boring
07:06 PM JT-Mobile: but bragging rights...
07:07 PM Tom_L: big frank(500lb) had a late model which was alot more fun
07:07 PM Tom_L: little frank drove it
07:07 PM Tom_L: has skin grafts all over his chest from a fire but kept doing it
07:08 PM Tom_L: those were the days...
07:09 PM JT-Mobile: texted my buddy with the C6 I'm in Collinsville
07:09 PM JT-Mobile: he said what's in Collinsville
07:09 PM Tom_L: Ok?
07:10 PM JT-Mobile: I said not much but it's 15 minutes from the track
07:10 PM JT-Mobile: forecast is awesome for tomorrow and sunday
07:14 PM Tom_L: it was a nice day here.. around 85 i think
07:14 PM Tom_L: should be about the same down there
07:16 PM Tom_L: looks like the weather is well south of Tulsa
07:18 PM JT-Mobile: yeah mid 80's here
07:28 PM JT-Mobile: https://doc.qt.io/qt-6.2/stylesheet-examples.html
07:30 PM Tom_L: that should help
07:32 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/rpi_mill_3/Screens/Gcode_dark.png
07:32 PM JT-Mobile: can't find the images for the examples
07:33 PM JT-Mobile: looks good, nice contrasrt
07:34 PM Tom_L: all i did was take the original and add qwidget black from yours
07:34 PM Tom_L: call it cheating.... meh
07:35 PM JT-Mobile: 220 221 what ever it takes
07:35 PM lcnc-relay: <ffffrf> damn, i did something crazy and switched the chips between the axis in the driver box and the Z still work but still does not change directions lol
07:36 PM Tom_L: can you put a border around the drop down menu boxes?
07:36 PM Tom_L: they could use a white 1-2px border
07:36 PM Tom_L: fff, check for a config problem too
07:36 PM Tom_L: make sure the pins map to where you think they do
07:37 PM JT-Mobile: like when hou press File?
07:37 PM Tom_L: yeah
07:37 PM JT-Mobile: hmm
07:38 PM Tom_L: it would draw attention to it more i think
07:38 PM Tom_L: Qmenu
07:40 PM Tom_L: Qmenu::item{border: 1px solid}
07:40 PM Tom_L: or such
07:40 PM JT-Mobile: https://doc.qt.io/qt-6.2/stylesheet-examples.html#customizing-qmenu
07:41 PM Tom_L: was looking at that i think
07:41 PM -!- #linuxcnc mode set to +v by ChanServ
07:43 PM Tom_L: is it Qmenu or QmenuBar?
07:44 PM Tom_L: QmenuBar is the one below it isn't it?
07:44 PM JT-Mobile: menu is the the one at the top menu bar is the tool bar I "think"
07:44 PM Tom_L: that was what i wondered
07:53 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/rpi_mill_3/Screens/20240705_194537.jpg
07:53 PM Tom_L: can't screen shot those
07:54 PM Tom_dev: QMenu{
07:54 PM Tom_dev: border: 1px solid white;
07:54 PM Tom_dev: }
07:56 PM JT-Mobile: looks good
07:56 PM Tom_L: working on hover and select
07:57 PM Tom_L: that makes the menu stand out a little
07:57 PM JT-Mobile: I "think" there is submenu controls as well
07:57 PM Tom_L: both have the border
07:57 PM Tom_L: recent file->
07:58 PM JT-Mobile: use a time delay on the screen shot]
07:58 PM Tom_L: didn't know about that
07:58 PM Tom_L: ahh
07:58 PM Tom_L: right in front of my eyes and never noticed it
08:08 PM Tom_L: JT-Mobile, http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/rpi_mill_3/Screens/File_menu.png
08:09 PM JT-Mobile: nice]
08:11 PM * JT-Mobile calls it a day
09:07 PM roycroft: on the way down, the ac in my new car kept things tolerable, even comfortable after a whle, but the air was by no means cold
09:07 PM roycroft: it was 39 degrees all the way down
09:08 PM roycroft: on the way back, it was the same at first, but the outside temp dropped to 34 as i got closer to home, and the ac started putting out cold air
09:47 PM lcnc-relay: <ffffrf> holy fuck
09:48 PM lcnc-relay: <ffffrf> i went down the rabbit hole of the components of the driver box
09:48 PM lcnc-relay: <ffffrf> and found a chip - sla7078 that seemed to be the main driver
09:48 PM lcnc-relay: <ffffrf> i found the pin responsible for cw / ccw and pinned the sherline dir pin directly to the chip, bypassing everything
09:48 PM lcnc-relay: <ffffrf> and it worked
09:49 PM lcnc-relay: <ffffrf> z axis moves both ways
09:49 PM xxcoder: awesome!
09:49 PM lcnc-relay: <ffffrf> i think if i just wire directly to this chip for both axis it may work, gonna solder some test wires lol
09:49 PM lcnc-relay: <ffffrf> still gonna replace everything but hey
10:11 PM Tom_L: looks like they have resistors between the pins & chips
10:12 PM Tom_L: also on the board the holes by 17, 15, 13, 12, 11, 10 , where do they go on the bottom side?
10:13 PM Tom_L: i dunno but that looks suspiciously like a way to enable A if they are jumper holes
10:13 PM Tom_L: or they could just be thru holes
10:15 PM Tom_L: maybe not looking at your pinout paper
10:19 PM Tom_L: those 100 ohm resistors may be there as a protecion on the input to those chips too
11:06 PM lcnc-relay: <ffffrf> oh my god sherline uses 1/4 inch shaft steppers and every other one is like 8-10mm I hate this company
11:06 PM lcnc-relay: <ffffrf> the shitty box is unusable
