09:57 AM -!- #linuxcnc mode set to +v by ChanServ
11:04 AM lcnc-relay: <skunkworks8841@> I have a shaper... lol - not quite that small...
11:43 AM lcnc-relay: <skunkworks8841@> The starter starts the loader!
11:44 AM lcnc-relay: <skunkworks8841@> I don't think it ever turned over that good...
11:57 AM xxcoder: nice
12:12 PM * roycroft is of to the old shop now for what he hopes is the last time
12:12 PM * roycroft crosses his fingers that everything will fit
12:13 PM bjorkintosh: safety first roycroft
01:22 PM * Tom_L wonders if he should update his RTAI to 5.4.90
01:22 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/RTAI_TEST/RTAI-5.4.290.png
01:23 PM Tom_L: different pc though
01:24 PM Tom_L: i still get an occasional following error
01:25 PM jpa-: if you don't get latency warnings, it seems unlikely following errors would be due to jitter
01:26 PM Tom_L: i'm not really sure what's causing it
01:26 PM Tom_L: i've fiddled with accel etc
01:26 PM jpa-: is it open-loop stepper or closed loop servo machine?
01:26 PM Tom_L: stepper
01:27 PM Tom_L: i have a wheezy install that works great but i can't run flex on it
01:27 PM Tom_L: still running an old D525 on that
01:28 PM Tom_L: i copied the config over and started fiddling from that
01:28 PM jpa-: a common cause for following error on stepper machine would be stepgen maxaccel/maxvel or the step timing making it unable to follow the path it is given
01:29 PM Tom_L: gecko using their numbers
01:29 PM Tom_L: and i've been tweaking the other 2
01:29 PM jpa-: if the wheezy install didn't have the separate axis/joint accel & velocity config, that could have some effect
01:30 PM Tom_L: i think it did
01:30 PM Tom_L: i'd have to look again
01:30 PM Tom_L: i try to keep them the same in both sections
01:31 PM Tom_L: i wonder if it would help to widen the pulse to the drives
01:32 PM jpa-: it wouldn't have an effect to the following error, because that is completely between linuxcnc's own components
01:32 PM jpa-: (assuming you don't have any feedback connected)
01:32 PM jpa-: you can try halscoping the feedback vs. command, but it can be quite tricky to figure anything from that
01:33 PM Tom_L: no feedback
01:34 PM Tom_L: the upgrade was also to help test the rtai
01:34 PM Tom_L: it's not the easiest install
01:34 PM Tom_L: you have to purge lcnc before you start
01:34 PM Tom_L: it's got it's own build
01:35 PM Tom_L: i could dd a spare drive which probably would be a good idea
01:42 PM Tom_L: i'm not gonna worry with it today
01:59 PM lcnc-relay: <skunkworks8841@> check your stepgen max accelleration setting
01:59 PM lcnc-relay: <skunkworks8841@> is it pid setup?
02:05 PM * JT-Shop takes 5 before tossing the bob crap disks and book into the burn barrel
02:14 PM bjorkintosh: bobcat ?
02:15 PM JT-Shop: bob cam
02:15 PM bjorkintosh: close.
02:15 PM bjorkintosh: :-D
02:15 PM bjorkintosh: bob cats are wild animals and should not be kept as pets.
02:15 PM JT-Shop: but bobcats are so warm and fuzzy
02:16 PM bjorkintosh: hah. I'm sure they are.
03:01 PM Tom_L: skunkworks, no
03:15 PM -!- #linuxcnc mode set to +v by ChanServ
03:16 PM Tom_dev: https://paste.debian.net/1377683/
03:16 PM Tom_dev: those are the numbers i currently have
03:17 PM Tom_L: Z is 3:1 others are direct drive
03:50 PM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=0v78IG9-BnQ
03:51 PM lcnc-relay: <skunkworks8841@> Tom_L: those numbers look good (2x accelleration) - but if your latency is pretty high - you might have problems not using pid
03:54 PM lcnc-relay: <skunkworks8841@> was really smoking for a bit.. it had oil on the exhast manifold. took a bit to burn it off.
04:12 PM JT-Shop: a loader?
04:19 PM lcnc-relay: <skunkworks8841@> yes
04:20 PM JT-Shop: sounded good
04:22 PM lcnc-relay: <skunkworks8841@> we overhauled the engine a few years ago. It is a 4 cylinder turbo. Always sounded good
04:23 PM lcnc-relay: <skunkworks8841@> it is heavy.. Leaves track imprints were ever it goes
04:23 PM JT-Shop: I could tell it was a loader from the tracks
04:23 PM lcnc-relay: <skunkworks8841@> yah - it certainly will spin the tracks
04:24 PM lcnc-relay: <skunkworks8841@> if you really work it
04:24 PM JT-Shop: my JD150 was a 6 way blade and had much taller bits on the tracks
04:24 PM lcnc-relay: <skunkworks8841@> right
04:24 PM JT-Shop: JD350 even
04:25 PM lcnc-relay: <skunkworks8841@> we have the parts machine which is identical carrage but blown engine. IT has a 6 way blade on it
04:25 PM xxcoder: bob cam that bad eh
04:25 PM lcnc-relay: <skunkworks8841@> also smooth tracks
04:25 PM xxcoder: website is very glossy lol
04:25 PM lcnc-relay: <skunkworks8841@> don't let them get your phone number...
04:25 PM JT-Shop: bob crap is the worst software I've ever attempted to use
04:26 PM xxcoder: I guess I know where funding went to.
04:26 PM xxcoder: the website.
04:26 PM JT-Shop: omg yes they never give up
04:27 PM lcnc-relay: <skunkworks8841@> they tried it at work.. I asked if they called a lot.. lol
04:27 PM lcnc-relay: <skunkworks8841@> they were like - omg - wtf?
04:27 PM JT-Shop: the bp came with a copy of bob crap and I made the mistake of upgrading
04:28 PM Tom_L: yay i think i got it fixed
04:28 PM JT-Shop: it?
04:28 PM lcnc-relay: <skunkworks8841@> what did you do?
04:28 PM lcnc-relay: <skunkworks8841@> FE?
04:29 PM Tom_L: before it wouldn't run 3 holes before it errored and now i was running my torture test & the hole patterns and did a 12 hole pattern with no problems
04:29 PM Tom_L: just slowed the accel etc down a bit
04:29 PM JT-Shop: what changed?
04:29 PM lcnc-relay: <skunkworks8841@> ah
04:29 PM lcnc-relay: <skunkworks8841@> that works too
04:30 PM Tom_L: it's been an ongoing problem i've been avoiding
04:30 PM JT-Shop: ah
04:30 PM lcnc-relay: <skunkworks8841@> I am running pretty high accelleration on the green machine with the RPI 4
04:30 PM Tom_L: i think it behaves a little different with flex
04:30 PM lcnc-relay: <skunkworks8841@> (doing the non-circular turning)
04:30 PM lcnc-relay: <skunkworks8841@> but it is running pid.
04:30 PM Tom_L: i basically ran all the numbers down by 5
04:30 PM Tom_L: roughly speaking
04:31 PM lcnc-relay: <skunkworks8841@> The gui shouldn't effect motion...
04:31 PM lcnc-relay: <skunkworks8841@> or do you mean - it causes higher latency?
04:31 PM lcnc-relay: <skunkworks8841@> that could be
04:31 PM Tom_L: well that's when i noticed it
04:31 PM Tom_L: i'll run it a while like this and see
04:31 PM Tom_L: it is alot better though
04:33 PM lcnc-relay: <skunkworks8841@> Neat!
04:36 PM JT-Shop: https://ibb.co/Swk9nK0k
04:37 PM Tom_L: got enough apps?
04:37 PM JT-Shop: mostly photos
04:37 PM Tom_L: wtf why all the jpg on the screen??
04:37 PM JT-Shop: download from nas the upload to website
04:38 PM Tom_L: nothing happens when i click on em
04:39 PM lcnc-relay: <skunkworks8841@> lol
04:39 PM JT-Shop: double click
04:39 PM Tom_L: ahh...
04:40 PM lcnc-relay: <skunkworks8841@> Now I can pull some really big tree's down the direction I want them to fall.
04:40 PM Tom_L: by the antenna?
04:40 PM lcnc-relay: <skunkworks8841@> yes.
04:41 PM lcnc-relay: <skunkworks8841@> the tree guys that came to cut trees down around the house found the big tackle..
04:41 PM lcnc-relay: <skunkworks8841@> block?
04:41 PM lcnc-relay: <skunkworks8841@> I never know what your supposed to call them
04:41 PM lcnc-relay: <skunkworks8841@> it is cooling off - time to do a little mowing in the woods
04:41 PM Tom_L: block & tackle but i'm not sure which part is which
04:42 PM Tom_L: the block is probably the pulleys
04:43 PM lcnc-relay: <skunkworks8841@> huh - internet says block and tackle - but for 1 pulley - I thought it wasn't
04:43 PM lcnc-relay: <skunkworks8841@> but whatever
04:43 PM Tom_L: yer askin the wrong guy
04:43 PM lcnc-relay: <skunkworks8841@> me too
04:43 PM JT-Shop: the round part is a sheave
04:45 PM bjorkintosh: block implies more than one sheave/pulley
04:45 PM JT-Shop: a block can have one sheave
04:45 PM JT-Shop: it's still a block
04:46 PM bjorkintosh: not typically. then you just say pulley.
04:46 PM JT-Shop: if you're a sailor it's a block
04:47 PM JT-Shop: pulley can be any number of sheaves
04:48 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/WUaj1tUDeFKkENJP9
04:48 PM lcnc-relay: <skunkworks8841@> foot for scale
04:48 PM JT-Shop: snatch block
04:48 PM lcnc-relay: <skunkworks8841@> ah
04:48 PM lcnc-relay: <skunkworks8841@> that makes sense
04:49 PM JT-Shop: usually used to change direction
04:49 PM JT-Shop: at least that's what we called them on the oil rigs
04:49 PM lcnc-relay: <skunkworks8841@> yes - that is what we always used it for - pulling trees down - usually attached around another tree
04:53 PM * Tom_L wonders what else to improve on this flex example
04:56 PM JT-Shop: I'm sure you can find something if you look hard enough
04:56 PM Tom_L: usually can
04:57 PM JT-Shop: I find stuff by using it
04:57 PM Tom_L: when i was testing i left alot of moves G1 that could be G0
04:57 PM Tom_L: but i may just leave those
04:57 PM Tom_L: for someone just starting to use them that may be polite
04:58 PM lcnc-relay: <skunkworks8841@> dad - when we got the k&t running with the original control - he never ran it above 40ipm..
04:58 PM JT-Shop: when I built my plasma I bitched so much about the final home move jeff or chris added the final move speed
04:58 PM lcnc-relay: <skunkworks8841@> (G0 was 200ipm)
04:59 PM Tom_L: heh, that was standard feedrates on my kid's mills at work
04:59 PM JT-Shop: the final move was so violent because it didn't have any acceleration it shook the whole machine
04:59 PM Tom_L: and ~2k rapids
04:59 PM lcnc-relay: <skunkworks8841@> I bet - I think the latest tormachs are 1000ipm
05:00 PM lcnc-relay: <skunkworks8841@> (the ones with linear rails)
05:00 PM Tom_L: those makinos don't mess around
05:01 PM lcnc-relay: <skunkworks8841@> linuxcnc has come a long ways since I started using it
05:01 PM Tom_L: oh hell yeah
05:01 PM lcnc-relay: <skunkworks8841@> (and I got into it around the change from emc1 -> emc2
05:01 PM lcnc-relay: <skunkworks8841@> it was so much better than turbocnc at the time
05:02 PM Tom_L: i followed it for a long time but fairly recently started using it
05:02 PM Tom_L: i think i remember the emc2 transition
05:02 PM JT-Shop: I started using emc when they came out with the livecd
05:02 PM lcnc-relay: <skunkworks8841@> that was my intro to irc and linux.
05:02 PM Tom_L: i'd been on irc quite a while
05:02 PM Tom_L: not here
05:03 PM JT-Shop: before that I never could get it installed from the bdi... Brain Dead Install I wonder if that's Paul
05:03 PM lcnc-relay: <skunkworks8841@> yes - that was paul corner
05:03 PM lcnc-relay: <skunkworks8841@> I used the bdi - got onto irc and cradek walked me through installing emc2 on it.
05:03 PM lcnc-relay: <skunkworks8841@> then - not to long after that was the ubuntu livecd with emc2
05:05 PM JT-Shop: I still have the bdi cd
05:16 PM Tom_L: JT-Shop, have you tried your hole pattern op since you did it?
05:16 PM Tom_L: using polar coordinates is actually pretty cool
05:16 PM JT-Shop: yup I made that part using it
05:16 PM Tom_L: not very well documented but cool
05:18 PM roycroft: hello, folks
05:18 PM Tom_L: well he's still alive
05:18 PM roycroft: i can now say something i was beginning to think i would never be able to say
05:18 PM roycroft: i am done moving!
05:18 PM roycroft: the pickup is very full, but it has every last item that intended to retrieve from the old place
05:19 PM Tom_L: did you drop off some you intended to discard?
05:19 PM bjorkintosh: they probably fell off the truck.
05:19 PM roycroft: no
05:19 PM bjorkintosh: congratulations roycroft.
05:20 PM roycroft: if you recall, i traded my trailer for getting the property cleaned up
05:20 PM Tom_L: yup
05:20 PM roycroft: i abandonded everything i did not want
05:20 PM roycroft: it's no longer my problem
05:21 PM roycroft: i pushed my back to its limit again, but that's ok
05:21 PM roycroft: the pickup can stay parked full of stuff for a day or two
05:21 PM roycroft: because it has no more loads to haul
05:23 PM JT-Shop: you still have to sell the old house
05:23 PM roycroft: yes, and that will happen soon
05:24 PM roycroft: but my realtor will be handling that
05:24 PM Tom_L: and make sure the trailer guy does what he said he would
05:24 PM -!- #linuxcnc mode set to +v by ChanServ
05:24 PM JT-Shop: that will be the most satisfying part of the whole operation
05:24 PM roycroft: that is still a concern
05:26 PM xxcoder: congats on finishing the emptyout
05:26 PM roycroft: not to mention i still have all this stuff to deal with at home now
05:27 PM Tom_L: at a reasonable pace though
05:27 PM roycroft: yes
05:27 PM * JT-Shop has been getting rid of a lot of stuff that is no longer needed to have fun
05:28 PM roycroft: it is just starting to sink in that i do not have to ever go back to the old house and haul stuff to the new house
05:28 PM roycroft: i already feel a huge relief
05:28 PM bjorkintosh: what a relief, huh?
05:29 PM roycroft: it's amost overwhelming
05:30 PM roycroft: it's like almost all my stress over the past year is gone
05:30 PM * JT-Shop is getting hungry for the deep fried wings with hot sauce
05:36 PM JT-Shop: transition can be a lot of work... I know changing from machine builder to whatever is a huge amount of work to re-imagine the shop
05:37 PM roycroft: yeah, and it's just beginning
05:37 PM roycroft: now i have a lot of sorting of things to do, and then a garage sale weekend or two
05:38 PM roycroft: and i need to get back to planning the roof reframing and reshingling on the shop
05:39 PM roycroft: that needs to happen this summer
05:42 PM roycroft: i am probably not going to unload anything today, but i should be able to work on the limit switches for the mini-router some more after i've rested from the moving endeavor
05:44 PM Tom_L: looks like the forum is down again
05:46 PM JT-Shop: up for me
05:47 PM Tom_L: same here now
05:48 PM Tom_L: do you know what HALCMD = save neta is?
05:49 PM JT-Shop: HALCMD is a command you can execute from th eini
05:49 PM Tom_L: right
05:49 PM Tom_L: who is neta though :)
05:50 PM JT-Shop: no clue
05:51 PM * JT-Shop calls it a night
05:53 PM Tom_L: skunkworks, how can you tell if you're using PID on an axis?
05:53 PM roycroft: neta frazier?
05:53 PM Tom_L: i do have some P I D FF0-2 entries int the joints sections
05:53 PM Tom_L: so maybe i am and don't realize it
05:54 PM Tom_L: i think i added those after JT suggested i should but not sure why
05:56 PM pcw---home: Tom_L If the pid.out pin is connected to a stepgen velocity pin, you are using PID feedback
05:58 PM Tom_L: ok i don't think i am
05:59 PM Tom_L: just on the spindle
05:59 PM pcw---home: If you get following errors, plotting them with halscope may give a clue as to what's happening
06:00 PM Tom_L: i adjusted the accel a bit and it seems much better but will watch it over time
06:00 PM Tom_L: i think it was too high
06:01 PM Tom_L: once adjusted i got no more errors at least for today
06:01 PM pcw---home: Just local feedback or feedback from an encoder?
06:01 PM Tom_L: open loop steppers
06:02 PM Tom_L: the spindle has an encoder
06:04 PM Tom_L: my test runs all 3 axis at once in all quadrants at ~150ipm
06:05 PM Tom_L: and some small helix moves which is what faulted it recently
06:10 PM pcw---home: what are the following error settings?
06:12 PM Tom_L: FERROR .050 MIN_FERROR .005
06:12 PM Tom_L: is that too high?
06:12 PM pcw---home: inches?
06:12 PM Tom_L: yeah
06:13 PM pcw---home: thats pretty high so a following error is pretty serious
06:13 PM Tom_L: maybe i should add a decimal to each one
06:13 PM pcw---home: What hardware?
06:14 PM Tom_L: gecko 203v with some 570inoz steppers
06:14 PM pcw---home: what interface hardware?
06:14 PM Tom_L: next time i'm out there i'll add a 0 to each and see what hapens
06:14 PM Tom_L: umm 7i90
06:15 PM Tom_L: direct on some 5mm ballscrews
06:15 PM Tom_L: z is 3:1
06:15 PM pcw---home: I would probably use a PID loop with the stepgen rather than the built in position mode
06:16 PM Tom_L: i've never messed with that type of setup
06:16 PM pcw---home: (the built in position mode has problems if you have large latency spikes)
06:16 PM Tom_L: i'm not running production with this thing... i mostly use it to test out things anyway
06:16 PM Tom_L: but yeah..
06:17 PM pcw---home: you can use pncconf or mesact to generate an example of the connections needed
06:17 PM Tom_L: yeah
06:18 PM Tom_L: i probably should use mesact or JT might scold me
06:18 PM pcw---home: properly setup the following error should be <.00005" in most cases
06:18 PM Tom_L: i know it should be alot lower than it is
06:19 PM Tom_L: i think i changed those early on during some test to get thru the test and kinda forgot i did
06:19 PM pcw---home: Yeah either will create a good example set of connections
06:20 PM Tom_L: ferror .00005 or min_ferror?
06:21 PM pcw---home: I would not set it that low just saying, when properly setup the actual errors are in that range
06:21 PM Tom_L: i realize that
06:21 PM pcw---home: But there is a known issue with the built-in position mode and servo thread jitter
06:22 PM Tom_L: ok
06:22 PM roycroft: time to work on the limit switches
06:22 PM roycroft: i am rested enough, i think
06:23 PM Tom_L: pcw---home, i did find out that preempt-rt seems worse on that parallel port interface than RTAI. i've been runing ntulinux's latest RTAI
06:23 PM Tom_L: or almost latest
06:23 PM Tom_L: there's not alot of difference between those 2
06:24 PM pcw---home: (which is why the setup utilities use the PID scheme) ideally PID should be used in the drivers position mode but that's a fair project...
06:24 PM Tom_L: i have the last build of RTAI on my test pc in the office
06:24 PM pcw---home: Also using the DPLL helps a lot
06:24 PM Tom_L: does the 7i90 support dpll?
06:24 PM pcw---home: All do
06:24 PM Tom_L: how do you enable that?
06:25 PM Tom_L: require a new bitfile?
06:25 PM pcw---home: The DPLL helps a lot with jitter issues
06:25 PM Tom_L: i did up a custom bit file for this thing
06:25 PM Tom_L: ages ago
06:26 PM pcw---home: Possibly if the desired bitfile doesn't have a "d" in the name
06:26 PM Tom_L: i'd have to open the vhd and see
06:26 PM Tom_L: i renamed it
06:27 PM pcw---home: basically just means you need:
06:27 PM pcw---home: (HM2DPLLTag, x"00", ClockLowTag, x"01", HM2DPLLBaseRateAddr&PadT, HM2DPLLNumRegs, x"00", HM2DPLLMPBitMask),
06:27 PM pcw---home: in the top line of the moduleID section
06:27 PM Tom_L: i think i've seen it in some vhd files
06:28 PM pcw---home: and then typically two lines in the hal file
06:29 PM Tom_L: it doesn't appear to be
06:29 PM pcw---home: # latch 200 usec before nominal read time:
06:29 PM pcw---home: setp hm2_[HOSTMOT2](BOARD).0.dpll.01.timer-us -200
06:29 PM pcw---home: setp hm2_[HOSTMOT2](BOARD).0.stepgen.timer-number 1
06:29 PM Tom_L: if i changed it just add it after (sserialtag......
06:29 PM Tom_L: on the next line
06:30 PM Tom_L: i'm not sure i still have webpack still loaded...
06:30 PM pcw---home: I usually put it at the top (not sure if thats needed)
06:30 PM Tom_L: ok
06:31 PM Tom_L: then add the 2 lines to the hal file
06:31 PM pcw---home: Just use the block copy/paste to move everything else down one line
06:31 PM Tom_L: yeah
06:32 PM Tom_L: it might be a while before i go that far
06:32 PM pcw---home: Not sure its needed but its should be the first register access
06:32 PM Tom_L: i'm getting pretty rusty on that stuff
06:33 PM pcw---home: you can send me your PINXXXX.vhd file if you wish, and I can do it
06:33 PM Tom_L: i think i made one for the 7i80 too since they're basically the same
06:33 PM pcw---home: (I've only done this about 5000 times...)
06:33 PM Tom_L: yeah you're busy enough as it is
06:34 PM pcw---home: poking around at some EtherCAT stuff
06:34 PM Tom_L: that seems to be the rage now
06:35 PM Tom_L: well at least it's there for later
06:35 PM pcw---home: yeah would be good to have some flexible misc I/O for Ethercat Systems
06:35 PM Tom_L: so the dpll thing doesn't get called in the pin list... it's just a function
06:36 PM Tom_L: called from the hal file
06:36 PM Tom_L: or set up from there
06:36 PM pcw---home: If it's an issue I can build firmware, I'm all setup so it only take me a few minutes
06:37 PM Tom_L: i'll keep that in mind.... i have alot else on my plate and don't have quite the play time as i did
06:37 PM pcw---home: Yes the DPLL normally has no pins (but it can) it has an external sync input and timer output
06:37 PM Tom_L: ok
06:38 PM pcw---home: but for LinuxCNC use the sync is a LinuxCNC read and the timer outputs are used internally
06:39 PM Tom_L: i'd have to check the mill --readhmid to double check which file this would be
06:39 PM Tom_L: i have several and i think it would include the A axis pins
06:40 PM Tom_L: i had to juggle things around to make it fit on the 7i47s
06:40 PM pcw---home: BBL Listening to some Kaputsin and making dinner... If you have firmware issues, jsu email me your current pinout files
06:41 PM Tom_L: thanks for the offer
06:44 PM Tom_L: i missed it in the file, the DPLL is there already
06:44 PM Tom_L: so all i need is to add the lines to the hal file
06:46 PM -!- #linuxcnc mode set to +v by ChanServ
06:46 PM Tom_dev: setp hm2_[HOSTMOT2](BOARD).0.dpll.01.timer-us -50
06:46 PM Tom_dev: setp hm2_[HOSTMOT2](BOARD).0.stepgen.timer-number 1
06:46 PM Tom_dev: aparently i already added that too
06:47 PM pcw---home: 50 usec is probably too tight for many systems
06:47 PM Tom_dev: 200?
06:48 PM pcw---home: 200 is better for most systems
06:48 PM Tom_dev: ok
06:48 PM pcw---home: Best to plot the following error to get some idea of the cause
08:53 PM lcnc-relay: <sloth288@> soganatsu@ sent dm
08:53 PM roycroft: i finished making the limit switch bracket, and i think i mounted it in a good location on the gantry side
08:54 PM roycroft: making the limit tabs is next, and that's going to be challenging without my mill/drill
08:54 PM roycroft: well, not really challenging, but tedious
08:58 PM xxcoder: nice
08:58 PM roycroft: pwd
08:58 PM roycroft: ack
09:01 PM roycroft: https://roycroft.us/Mini-Router/Y_axis_Limit_Switches.jpeg
09:01 PM roycroft: there you go
09:01 PM roycroft: i know some of you love the life vicarious :)
09:02 PM xxcoder: interesting! and thanks lol
09:02 PM xxcoder: probably want to do little bit of deburring it looks like
09:02 PM Tom_L: where's adjustment?
09:02 PM roycroft: is that something you might have done?
09:02 PM Tom_L: not alot
09:02 PM roycroft: there is a t-slot along the length of the bed on the side
09:02 PM roycroft: that is the adjustment
09:03 PM Tom_L: i have one that get's pretty darn close to the frame
09:03 PM Tom_L: when it homes
09:03 PM Tom_L: i've 'adjusted' it some
09:03 PM xxcoder: I dont know, my plans was quote vague. I was thinking maybe place switch on gantry side, but only one, and using t slot to place flange or something
09:03 PM roycroft: no deburring needed at all
09:03 PM roycroft: it's pretty smooth already
09:03 PM Tom_L: i also added hard stops to the ends
09:03 PM xxcoder: oh bores dont have burr?
09:04 PM roycroft: not the ones i made
09:04 PM roycroft: there are minor burrs on the gantry side
09:04 PM xxcoder: ya what I meant :D ok
09:04 PM roycroft: but they are pre-existing, and don't affect operation
09:04 PM roycroft: i'm planning on cleaning up the gantry sides when i'm done with the rest of the work, before finaly assembly
09:05 PM xxcoder: makes sense, since there might be more stuff to do
09:05 PM roycroft: yes, i'm sure i'll be disassembling/reassembling parts of the machine several times before i'm done
09:06 PM roycroft: and it's kind of dirty from machining wood in the past
09:06 PM roycroft: when everything is fitted i'll probably completely disassemble the entire machine, clean and lube it, and reassemble
09:07 PM xxcoder: yeah grease on it is years old, best to clean that out
09:07 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/X_Axis_endplate.jpg
09:07 PM roycroft: so that it will be clean and new looking for the first few seconds
09:07 PM xxcoder: plus yeah I didnt clear some wood out
09:07 PM roycroft: until i start using it
09:07 PM Tom_L: i'd rather have it hit that than run off the end with the balls falling out
09:07 PM roycroft: my machine already has end stops
09:07 PM xxcoder: definitely. mini rouer have ends so its impossible to run off
09:08 PM Tom_L: this was all diy
09:10 PM roycroft: this is not a high-performance high-accuracy machine, and i do not intend to attempt to make precise parts with it in a production environment
09:10 PM roycroft: but it should be able to produce some good parts
09:11 PM xxcoder: I remember doing basic checkup of machin, so there probably wont be screws retaining bearings like ones capt had gotten
09:11 PM xxcoder: but yeah definitely needed more in-depth checks
09:11 PM roycroft: well the cleanup and relube will afford an opportunity for that
09:11 PM xxcoder: indeed.
09:12 PM roycroft: i have moved it with linuxcnc in all three axes from end to end of each axis
09:12 PM roycroft: i've not attempted to power up the spindle yet though
11:59 PM xxcoder: cnc engineering a no edge brownie
