12:14 AM Tom_L: ok i think it's fixed
12:19 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin.jpg
12:19 AM Tom_L: changed the lead in / out to arc
12:19 AM XXCoder: g2/g3 exit eh
12:19 AM XXCoder: tend to be great idea. leaves less of a mismatchj
12:22 AM XXCoder: file refuses to open
12:23 AM XXCoder: trying again
12:23 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arctest.txt
12:23 AM Tom_L: try that
12:24 AM XXCoder: gedit seem to hate it, so opened using libreoffice
12:24 AM Tom_L: i renamed it to .txt
12:24 AM Tom_L: and now it's bedtime
12:25 AM XXCoder: hmm
12:25 AM XXCoder: seems it does g2 a little then moves down z then moves more?
12:26 AM XXCoder: yah
12:26 AM XXCoder: night tom
12:27 AM Tom_L: it does multiple arcs due to the way i wrote the macro
12:27 AM Tom_L: or it could do just one helix
12:28 AM Tom_L: after the leadin, you could delete all but the last arc before the leadout move
12:29 AM Tom_L: but you'd have to add a P word if you did
12:29 AM XXCoder: it depends on machine, but some allow you to also lower z yeah
12:30 AM Tom_L: nice thing is i don't have to edit the file after i post it at all
12:31 AM XXCoder: thats good
12:31 AM Tom_L: that took a while to get just right
12:32 AM Tom_L: i didn't set any z clear moves in that, it's just for testing the macro
12:32 AM XXCoder: no wonder I crashed my machine ;)
12:33 AM XXCoder: ill test it with rolfmill vismach later
12:33 AM Tom_L: i could go back in and change it but i'm not gonna tonight
02:03 AM Deejay: moin
02:03 AM pink_vampire: hi Deejay
02:04 AM Deejay: hey pink
02:06 AM XXCoder: yo
02:08 AM pink_vampire: i need to build some parts for the Y and Z axis
02:08 AM XXCoder: i checked out my 3d printer
02:08 AM XXCoder: its y axis belt holder at one end broke lol
02:09 AM XXCoder: so its not running machine now
02:11 AM pink_vampire: can you fix it?
02:11 AM XXCoder: looks like no, as belt bearing is gone
02:11 AM XXCoder: but not worried, i am still waiting for obsidian printer
02:12 AM XXCoder: I can fix this junk machine with obsidian later
02:13 AM pink_vampire: i'm use the printer to make parts for the mill
02:16 AM XXCoder: nice
02:16 AM XXCoder: I did make some before 3d printer broke down
02:16 AM XXCoder: i added rpm detector to spindle
02:16 AM XXCoder: planned to make it into PID spindle detect so if it slows down by cutting it will supply more power.
02:19 AM pink_vampire: no idea why you need it on a small machine like yours
02:19 AM XXCoder: old machine I dunno, I might convert it to plotter
02:20 AM XXCoder: pid for spindle? well i do want to cut alum on it
02:20 AM XXCoder: its frame is strong enough but spindle eh
02:20 AM XXCoder: I wanted it to detect spindle rpm and ramp up power to keep rpm going
02:22 AM XXCoder: cnc router project is dead for next forseenable future though, no dang room :(
02:38 AM Vq: I can sympathise with that, my workshop is overflowing.
02:39 AM XXCoder: my workshop isnt overflowing
02:39 AM XXCoder: it just dont exist heh
02:39 AM pink_vampire: finish to set the homing stuff, but only the x axis limit the mounted O_O
02:40 AM gloops: youll have to give up a bedroom lol, priorities first
02:43 AM XXCoder: lol
03:20 AM PL7icnc: Morning
03:20 AM PL7icnc: Mr gloops
03:20 AM PL7icnc: 10,000 klicks past
03:21 AM PL7icnc: Q is the TVP in the Stretch ISO provided
03:21 AM PL7icnc: TCP M128
03:32 AM PL7icnc: some MOD here from the Forum
03:33 AM PL7icnc: the Software of the Forom isent that userfriendly on how to connect eatch other NO Problem
05:33 AM jthornton: morning\
05:33 AM XXCoder: good morning sir jthornton
05:35 AM jthornton: frost advisory for tonight
05:36 AM XXCoder: cold creeping in again eh
05:36 AM jthornton: windows have been open here for the last few days I guess that's why I've over slept
05:38 AM XXCoder: fresh air helps you sleep huh?
05:38 AM jthornton: cool temps I guess dunno
05:45 AM jthornton: https://www.youtube.com/watch?time_continue=64&v=e8TUwHTfOOU
05:46 AM XXCoder: lol
06:21 AM veek: https://www.engineeringforchange.org/news/how-to-make-penetrating-oil/
06:24 AM XXCoder: interesting
06:24 AM XXCoder: from what i understand pretty lot of oils is better than wd40 anyway
06:25 AM syyl_: from what i understand: penetrating oils are a waste of time ;)
06:25 AM XXCoder: just more hammer eh heh
06:26 AM syyl_: frozen bolt? just machine it out and dont bother soaking it for days
06:26 AM syyl_: love it when you get a part with a broken/stuck bolt
06:27 AM syyl_: "yeah, i tried already penetrating oil, heat, chisels, an ez-out and everything"
06:27 AM syyl_: and the surounding area looks like a crater-field
06:27 AM syyl_: preferable with an broken ez-out in the bolt ;)
06:56 AM * SpeedEvil ponders selling ez-out--ez-outs made from solid diamond.
06:58 AM Tom_L: morning
07:03 AM jthornton: morning
07:07 AM Tom_L: jthornton, started reworking the macro last night
07:07 AM jthornton: what are you doing to it?
07:07 AM XXCoder: it now finishes cuts before it starts
07:07 AM XXCoder: ;)
07:08 AM Tom_L: when you figured those percentages what diameter did you calculate them from?
07:08 AM jthornton: the hole diameter
07:08 AM Tom_L: i changed the leadins to arcs
07:09 AM Tom_L: so the first cut would be something like 60% from the hole
07:09 AM Tom_L: (i don't have the percentages in front of me)
07:10 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin.jpg
07:11 AM Tom_L: i'll see how hard it is to change to percent
07:11 AM jthornton: 2 pass 65/35
07:11 AM Tom_L: may just leave it since it works ok and i'll probably be the only one ever to use it
07:11 AM jthornton: 3 pass 50/30/20
07:12 AM jthornton: 4 pass 40/27/20/13
07:12 AM Tom_L: thanks
07:13 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/ThreadMill_Multi_arc.mcl
07:13 AM Tom_L: there's the macro so far
07:16 AM Tom_L: have you done anything with external threads yet?
07:26 AM jthornton: no
09:38 AM Roguish_ is now known as Roguish
09:49 AM pink_vampire: https://imgur.com/a/hW6JIXf
09:51 AM Tom_L: gonna add some switches?
09:53 AM pink_vampire: yeah, this is the z axis limit switch mount
10:05 AM gregcnc: playdoh?
10:21 AM Roguish_ is now known as Roguish
10:33 AM gloops: yes, no damage possible
10:34 AM Tom_L: hah
10:50 AM gregcnc: winter wonderland in Chicago
10:52 AM Tom_L: more snow ehh?
10:54 AM gregcnc: it's starting to accumulate on the roads and not supposed to stop until tonight
10:54 AM Tom_L: lovely
10:59 AM Tom_L: is that normal for this time of year up there?
11:34 AM Elmo40: I'm in Southern Ontario. Only rain here.
11:51 AM flyback is now known as phlyback
11:51 AM phlyback is now known as flyback
11:51 AM Elmo40: it is only 35F, though. If winds pick up it might also snow.
11:53 AM flyback: https://www.youtube.com/watch?v=ZmoOOuSRbdg
11:53 AM flyback: BMCC
11:53 AM * flyback SINKS HIS TEETH INTO Elmo40'S LEG MEAT
11:53 AM flyback: BITE MY "CANUCK"..............................................................................................CANUCK!
11:53 AM flyback: EH?-HOLE!
01:28 PM gregcnc: last time I remember this much snow this late in the year I was a kid
04:21 PM Deejay: gn8
06:35 PM * Elmo40 doesn't taste too well... so much coolant and Al chips
07:52 PM jelly is now known as Are
07:53 PM Are is now known as jelly
10:30 PM cryptg: Are these good to use on linuxcnc?
10:30 PM cryptg: C10 - BI-DIRECTIONAL PARALLEL PORT BREAKOUT BOARD https://www.amazon.com/dp/B06Y3M43JT/ref=cm_sw_r_cp_apa_i_cz.SCbGY5HEZ2
10:30 PM Tom_L: i think some have used them
10:31 PM cryptg: I'm not going for a Mesa setup on this machine yet, so dual parallel and maybe 2 of those is my current plan
10:32 PM Rab: Yeah, there are a couple people here who have used those. pink_vampire, maybe.
10:32 PM cryptg: I bit the bullet and ordered 3 closed loop nema 23 steppers last night
10:32 PM cryptg: This is all so new to me...
10:33 PM cryptg: What is the advantage other than the selectable pull up jumpers on it?
10:34 PM cryptg: I was honestly going to go for a plain and simple db25 breakout connector with no extra components
10:35 PM cryptg: But then I saw that and this
10:35 PM cryptg: Alloet Mach3 CNC Stepping Motor Driver Interface Adapter Breakout Board + USB Cable https://www.amazon.com/dp/B01MTXI1C6/ref=cm_sw_r_cp_apa_i_-R.SCbYN49X8A
10:35 PM cryptg: But I don't know how I feel about a non replaceable relay
10:35 PM Rab: It's a good idea to use level shifters, which that board appears to have. It's a very good idea to have optical isolation, which I don't think the board includes.
10:36 PM cryptg: No it doesn't I don't think
10:36 PM cryptg: I was going to wire my own
10:37 PM cryptg: But then seeing that second one has them I'm unsure
10:37 PM Rab: cryptg, I have one of those and it works OK. It includes level shifters, and optoisolators on some channels. The quality is typically terrible chinesium, however, and there are many reports of design and QC problems.
10:38 PM cryptg: Sheesh
10:38 PM Rab: They're cheap enough that you could get both and try them out.
10:38 PM cryptg: Buy and rebuild maybe?
10:38 PM cryptg: True
10:38 PM Rab: The relay is probably the most reliable part on that board.
10:38 PM cryptg: Hahaha
10:40 PM Rab: They are very simple--no real onboard logic, what you see is what you get. If you have electronics skillz, it'd be pretty easy to troubleshoot and repair. But you might rather be troubleshooting and repairing other things.
10:42 PM cryptg: I was going to get a plain old connector and hook up a few pc817 optos on it
10:43 PM cryptg: But I may as well givw it a shot for now
10:43 PM Rab: Sure, that's fine.
10:43 PM cryptg: Also for anyone interested check these monsters out
10:43 PM cryptg: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F163524784676
10:43 PM _unreal_: cryptg, There are 2 different board versions in that first link
10:44 PM cryptg: I ordered these
10:44 PM cryptg: unreal, I don't see an option
10:45 PM cryptg: I did read the comments about a socketed version though
10:45 PM _unreal_: option?
10:45 PM cryptg: As in I don't see another link in amazon
10:45 PM _unreal_: I'm just saying that parallel port thing
10:45 PM cryptg: Oh
10:46 PM _unreal_: read the comments I have not. but they are showing different board versions
10:46 PM Rab: Yeah, I noticed that.
10:46 PM _unreal_: in the photos
10:46 PM _unreal_: cryptg, I'm slowly working on getting the tinkerboard up and running with linuxcnc
10:47 PM cryptg: Hahaha hit or miss on what I'd end up with
10:47 PM _unreal_: trying to get it to work with the GPIO
10:47 PM cryptg: Any progress?
10:47 PM _unreal_: https://photos.app.goo.gl/GvprVxFfbKAWY7VR7
10:47 PM cryptg: And any advantages?
10:48 PM _unreal_: well if I get it up and running fully. ya your talking about a tinkerboard with a 28pins of GPIO
10:48 PM cryptg: Ooooooh nice!
10:48 PM _unreal_: so far i've gotten the RTOS up and working, I've gotten linuxcnc FINALLY compiled and working
10:48 PM cryptg: I had been aiming for a mini stand alone too
10:49 PM _unreal_: now I have a few people slowly helping me try to get the GPIO going
10:49 PM _unreal_: I sell those shells
10:49 PM cryptg: That's awesome
10:49 PM _unreal_: any color
10:49 PM cryptg: I'm looking forward to that, most likely for my next machine
10:49 PM _unreal_: to what?
10:50 PM _unreal_: hello?
10:51 PM cryptg: Sorry
10:52 PM cryptg: I'd like an rpi or something similar for my next machine
10:52 PM cryptg: It will be made portable
10:52 PM _unreal_: the tinkerboard is one of the more powerful boards out there and follows the RPI form factor
10:52 PM cryptg: Likely 1.5"x1.5"
10:52 PM _unreal_: tinker is 2x CPU and 2x ram
10:53 PM _unreal_: sudo apt update
10:53 PM _unreal_: arg...
10:53 PM cryptg: That would be great, I was told to avoid it, at least for now, so I decided to build a bigger one using a tower for linuxcnc
10:53 PM cryptg: That's awesome, I hadn't even heard of it
10:54 PM _unreal_: there are 2 versions
10:54 PM _unreal_: non S and S version
10:54 PM _unreal_: only difference is 2x the $ for the s version and it only has an added emmc and other minor changes.
10:55 PM cryptg: Hmm
10:55 PM _unreal_: the addon's are NOT worth the aditional price
10:55 PM _unreal_: IMO
10:55 PM cryptg: I was going to say
10:55 PM _unreal_: I got my tinker for $50
10:55 PM cryptg: If processing power and ram is the same may as well go cheaper
10:55 PM cryptg: Wow same as an rpi
10:56 PM cryptg: Didn't expect that
10:56 PM _unreal_: if you look up some benchmarks between the 2 the tinker shreads the rpi
10:56 PM _unreal_: If you do decide to get one. READ MY POST. https://github.com/berinc/Asus-Tinker-Board
10:58 PM cryptg: Seems like you're doing some decent work
10:58 PM _unreal_: I'm not so handy on the coding side, but everything else i'm a pro
10:59 PM _unreal_: the shell's I get request's about once a month.
11:00 PM _unreal_: last one I did the person paid a little extra to have me paint it racing RED with white racing strips down the middle
11:00 PM _unreal_: no phtoos stupidlly
11:00 PM cryptg: Nice
11:01 PM cryptg: I'm just getting started on this stuff so I'm learning as I go, I do work with omron and taking lessons on programming soon
11:02 PM cryptg: Not for omron
11:02 PM cryptg: I happen to work at a steel manufacturing site and maintain all the automated machinery
11:05 PM _unreal_: usa?
11:06 PM cryptg: Yep
11:07 PM _unreal_: well depending on your plans if you have interest in a SUPER custom shell let me know
11:08 PM _unreal_: mine are very light, fiberglass and very customizable. and EASY to work on
11:12 PM cryptg: Great
11:12 PM cryptg: Will let you know if I need ot
11:14 PM cryptg: Alright guys I'm out
11:58 PM gloops: job kept me out of the garage for 6 weeks, now im finally free again shes booked a few nights away! ffs
