01:50 AM PL7icnc: pcw_home, still online
01:54 AM PL7icnc: pcw_mesa, Online
02:13 AM tumdedum_ is now known as tumdedum
02:46 AM PL7icnc: is there somone here named Andy in Forum or BigT
03:38 AM rmu: PL7icnc: just ask
04:19 AM Deejay: moin
05:00 AM Tom_L: 23F Hi 57... looks like spring is back
05:06 AM jthornton: 21°F High 49°F and sunny yep spring
05:07 AM XXCoder: heys
06:33 AM PL7icnc: Someone here of Modaerator forum
06:33 AM PL7icnc: All i Post is gone away
06:33 AM PL7icnc: Am i missing somthing
06:36 AM jthornton: did you just register?
06:37 AM PL7icnc: yes about 3hr ago
06:38 AM jthornton: you have to wait for a moderator to approve your first post
06:38 AM jthornton: that is to weed out spammers
06:42 AM PL7icnc: ok
06:42 AM PL7icnc: You arent BigJ in the Forum
06:45 AM jthornton: aye
06:45 AM jthornton: not big anymore lol lost 65 pounds of extra weight
06:46 AM PL7icnc: Can You compile a Mesa Bit if i provide pin and vhd
06:46 AM PL7icnc: for 7i92
06:47 AM PL7icnc: i realy need to change this
06:48 AM jthornton: no, I've never done that... Peter is the man for that job
06:49 AM PL7icnc: i did send him the files if you are on pcw
06:51 AM rmu: PL7icnc: it is not _that_ hard to do yourself, see http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php
06:52 AM PL7icnc: yes but it needs 7GB Download
06:54 AM rmu: ok, that may be an issue...
06:54 AM Tom_L: depends how bad you want it
06:55 AM PL7icnc: Bad ?
06:55 AM PL7icnc: i changed the vhd file and the pin
06:56 AM Tom_L: i would do it but i'm walking out the door for a few hrs
06:57 AM Tom_L: pcw will likely be awake in a few hrs
06:58 AM jthornton: he is usually up pretty early
07:00 AM PL7icnc: What Timezone is he In
07:00 AM PL7icnc: Is this Mesa Direct
07:00 AM rmu: pcw is mesa
07:01 AM jthornton: Peter is in California
07:01 AM rmu: probably UTC-8
07:01 AM PL7icnc: i got Time
07:01 AM PL7icnc: 26th Jan next Event
07:02 AM PL7icnc: ok Thank you all for the Information im Off
07:02 AM rmu: i would try to get the download ;)
07:15 AM * jthornton finally figured out the right qbutton thing to look for...
01:14 PM sensille: with a largish gcode file loaded (5MB), jogging via keyboard gets very sluggish. is that normal?
01:14 PM gloops: cant say ive noticed that
01:15 PM sensille: correlation count: 1
01:15 PM sensille: first time larger gcode file, first time sluggish
01:16 PM gloops: so like lagging? not a command in the g code
01:17 PM gloops: i had around 50000 lines loaded didnt notice anything
01:19 PM sensille: the gcode runs fine, but jogging has lag, yes. especially if i relase a key, it continues for several 1/10s
01:22 PM gloops: touch off etc before loading would get around it i suppose
01:24 PM sensille: when it's finished i'll load a short file and see if it goes away
01:25 PM gloops: good idea
01:25 PM sensille: also f360's adaptive clearing fails to convince me yet
01:27 PM gloops: ChunkyPuffs was saying its great - ive not tried it yet, whats the issue you see with it?
01:31 PM skunkworks: ls
01:31 PM sensille: it's making so many movements that the surfaces don't look good, but that is probably due to my cheap machine. also i have no experience, so don't put any weight on my opinion.
01:33 PM gloops: maybe some trial and error required, finishing pass etc for a good finish, im hoping to try it out over the xmas holiday
01:46 PM syyl: adaptive is a roughing strategy
01:47 PM syyl: and it allows to work shitty materials dry, with bad lubrication or at all
01:47 PM gloops: excellent
01:47 PM syyl: but its not the saviour of machining as some people want to put it
01:48 PM syyl: sometimes its just stupid slow ;)
01:49 PM gregcnc: but you don't want to slot the stupid way
01:51 PM gloops: its better to watch anyway
01:51 PM gregcnc: watch?
01:52 PM syyl: AAAARG
01:52 PM syyl: just because one person cant slot on a cnc
01:52 PM gregcnc: lol
01:52 PM syyl: i want to bang my head against the wall when i see contouring of parts by adaptive slotting
01:52 PM syyl: thats so wrong in every possible aspect
01:53 PM rmu: try cutting a slot in thin pure aluminium
01:53 PM rmu: dry
01:53 PM rmu: (al99,5)
01:54 PM syyl: yep
01:54 PM syyl: single flute, very shallow doc, insane high feed, everything will be fine
01:56 PM rmu: in theory, but practically this insane high feed is a problem
01:56 PM rmu: i admit it is a strange application ;)
01:56 PM syyl: i have pure gold on the machine at the moment
01:56 PM syyl: speaking of soft, gummy materials
01:57 PM syyl: for very anoying reasons i can not run cooleant nor airblast
01:57 PM syyl: to make it easier, the largest cutter the contour allows is a 0,8mm endmill ;)
01:58 PM Rab: syyl, annoying reasons of material reclamation?
01:58 PM syyl: partialy, yes
01:58 PM syyl: i have of course to collect the chips
01:58 PM syyl: and the part itself doesnt allow for cooleant either
01:58 PM syyl: my foreman obviously decided to give all the shit nobody else has patiente for to me ;)
01:59 PM gregcnc: vacuum filter to collect the gold?
02:01 PM syyl: i tried that, but the vacuum setup i have is a bit anoying to use on larger parts
02:01 PM syyl: right now i have the machine run the part over night
02:01 PM syyl: and i come in in the morning, brush up the chips and call it done
02:04 PM gregcnc: day job is also machining?
02:05 PM syyl: kinda
02:06 PM syyl: machinist in a prototypeshop
02:06 PM syyl: its sometimes more like building airfix kits ;)
02:07 PM cpresser: syyl: i used a box to catch the gold chips: https://ca.rstenpresser.de/~cpresser/tmp/pictures/_unsorted/gooold.jpg
02:08 PM cpresser: but in the end, there were very few chips (I just surfaced those cast parts), so it was not worth the effort to recycle them
02:12 PM sensille: re sluggish: the gcode has 250k lines. when i switch to the pure coordinate view, the sluggishness is gone. preview, it's back
02:15 PM cradek: since the preview of a program like that isn't very useful, you might want to add a comment (AXIS,stop) that makes the preview stop early
02:16 PM sensille: i'd still expect the keyboard even to have priority
02:16 PM cradek: if you need realtime response you must use realtime inputs, which the keyboard and gui are not
02:16 PM cradek: so get a jogwheel (not a usb one, get one that hooks to realtime encoder inputs)
02:22 PM sensille: ok. so it's not unexpected
02:40 PM rob_h: hi, i have a resolve with specs exitation 15v amplitude 10v frequency 3.5Khz, would this work on a 7i49 or hv version?
02:41 PM Papagno: Hi at all. On actual master have a problem with spindle at speed pin. If command m3 s10000 and abort first the receive signal spindle at speed = true and affter command g1 z-10 f100 , the g1 not is executed remain append and cnc in run . the axis wait spindle at speed, but i first have abort .this is test on actual master. the same problem is with M5 first the receive spindle at speed = true
02:42 PM pcw_mesa: should work with HV
02:46 PM pcw_mesa: it would work with the normal 7I49 also but just the first 3 channels (that you can jumper for 1:1 vs 2:1)
02:47 PM rmu: Papagno: what do you mean with "if command m3 s10000 and abort first"
02:47 PM Papagno: actual master have problem with signal spindle.x.at-speed
02:48 PM Papagno: command m3 s5000
02:49 PM rmu: and?
02:49 PM Papagno: if signal spindle.0.at-speed is false and you abort or start a m5 and after command g1 x10 y20 f1000, the axis not move
02:50 PM Papagno: the problem than when you command a m3 S and not have spindle.0.at-spped
02:51 PM rmu: you enter the g1 command at MDI ?
02:52 PM Papagno: yes in MDI
02:52 PM Papagno: but now test in auto wait
02:55 PM rmu: hmm. don't know. i see this behaviour when pausing a program, stopping the spindle via GUI and then when continuing it waits until spindle is turned on and spindle.x.at-speed is true before doing any move
02:55 PM rmu: but not in MDI
02:56 PM Papagno: in auto the same.
02:57 PM Papagno: if you command m3 s24000 after have g1 x-3 f1000 and m30 : the axis not move for 6 second, when the spindle.0-at-speed is true , the axis move and this is correct
02:57 PM rmu: if you issue m3 then the control should wait until spindle at speed is true
02:58 PM Papagno: the problem than when in ramp i stop machine , because have see a problem . after if command a g1 it not is executed
02:59 PM rmu: even if you restart the spindle the g1 is not executed?
03:05 PM syyl: cpresser, i end up with roughly 20g of chips per part ;)
03:10 PM Papagno: the g1 is executed only if have spindle-at-speed true, this is ok, but not is ok if i have coomand m3 s24000 and stop machine after command g1 and it not is executed
03:12 PM pcw_mesa: its not executed even if spindle at speed is true?
03:15 PM Papagno: example time ramp for m3 s24000 is 6 second, the inverter after 6 second send out digital output, connect at pin spindle-at-speed
03:16 PM Papagno: ccommand m3 s24000
03:16 PM Papagno: wait 6 secod
03:16 PM Papagno: the signal spindle-at speed is true
03:16 PM Papagno: g1 is executed
03:16 PM Papagno: this is ok
03:16 PM Papagno: another case
03:16 PM Papagno: m3 s24000
03:17 PM Papagno: wait 3 second , stop machine
03:17 PM Papagno: the signal spindle-at-speed is false , because the ramp not is complete
03:17 PM Papagno: run g1 , in this case not is executed
03:18 PM Papagno: after a abor or m5 the loop the spindle -at -speed will reset , but not fuction
03:19 PM Papagno: you can test it on axis, disconnect the spindle.0.at-speed and setp spindle-at speed false
03:19 PM Papagno: run m3 s5000
03:20 PM Papagno: after pusch abort or estop
03:20 PM Papagno: after comman in mdi g1
03:20 PM Papagno: it not is executed
03:24 PM pcw_mesa: OK I guess I dont understand, that sounds like correct behaviour to me (no motion unless spindle at speed is true)
03:29 PM rmu: Papagno: what happens if you issue m5 before g1
03:31 PM rmu: ok
03:32 PM rmu: < Papagno> after a abor or m5 the loop the spindle -at -speed will reset , but not fuction
03:33 PM rmu: Papagno: perhaps you should open issue on github, this really sounds like a bug.
03:34 PM sensille: if i use 3d adaptive clearing for roughening, what is the finishing step? contour?
03:37 PM Papagno: pcw_mesa, If command m3 s24000 and not have true spidle-at-speed and you reset for stop spindle , after if command g1 not move , this no corret. if i have aborted , normally i can move in g1 , because not command another m3
03:37 PM pcw_mesa: does it work if spindle at speed is true?
03:37 PM Papagno: If command m3 s24000 and not have true spidle-at-speed and you reset for stop spindle , after if command g1 not move , this no corret. if i have aborted , normally i can move in g1 , because not command another m3
03:38 PM Lcvette: pcw_mesa: I am getting ready to wire in a MPG and I am confused now as to the method I should be connecting it. it is a 100PPR and it has switches for various outputs for the different step rates, I read through the forum and saw it could be either connected on inputs 16-19 or to an encoder channel on the 7i77.
03:38 PM Lcvette: it dies have detents on the encoder, I am guessing they are 100 per revolution without counting them
03:39 PM Papagno: yes it work with spindle is true , but you thing you have command m3 and have see tool not in good position, press emergency , after machine on , after g1 for move in mdi tool in another position, the axis not move
03:39 PM Lcvette: would I be best served connecting them to the 16-19 on TB7 and then I think I read i need to setup the 7i77 by flashing it for that?
03:39 PM pcw_mesa: Papagno: I'm just not sure if spindle at speed is expected to be true if 0 spindle speed is requested (and 0 is reported) i
03:41 PM pcw_mesa: I still think the may be OK, just that your spindle at speed is not correct when requested and actual are 0
03:42 PM pcw_mesa: Lcvette if you have detents its usually better to use the 7I77s MPG inputs since they have a 1X mode
03:42 PM Lcvette: ok
03:42 PM Lcvette: thanks!
03:45 PM pcw_mesa: Lcvette: no flashing needed, its just a hal file option
03:46 PM Lcvette: oh ok
03:46 PM Lcvette: even better
03:47 PM Papagno: pcw_mesa, yes Peter , but if i have abort or press emergency and after command g1 , i thing it normally move, but now not move and this not is ok
03:47 PM Papagno: pcw_mesa, understand problem
03:48 PM pcw_mesa: Is this a change from 2.7 behaviour?
03:49 PM Deejay: gn8
03:49 PM Papagno: pcw_mesa, this is after merged patch for fix problem the blend arc on actual master
03:49 PM Papagno: pcw_mesa, abot apply 2 or 3 week before
03:50 PM pcw_mesa: Seems like it would be more related to the multi spindle patch
03:51 PM Papagno: pcw_mesa, no the problem not is multispindle, i thing pach the TP for fix the velocity 0 when move in blend arc to arc
03:52 PM pcw_mesa: thats very strange, are you saying that earlier versions allowed motion when spindle-at-speed was false?
03:52 PM Papagno: pcw_mesa, #504
03:53 PM Papagno: pcw_mesa, rene-dev have close this point
03:54 PM Papagno: pcw_mesa, eb8d43fad3539c82e212c5c65be12b6f62ec5141
03:55 PM XXCoder: is it really nesscary to ping someone each time you say something?
03:56 PM Jymmm: XXCoder: yes
03:56 PM Jymmm: XXCoder: I thik it is
03:56 PM Jymmm: XXCoder: dont you?
05:25 PM jthornton: jeez why is backing up such a pain in a a$$ borg is so complicated
05:27 PM rmu: jthornton: https://gist.github.com/obilodeau/9f0fecdcad023ea4d7ea797d2aa73245
05:29 PM jthornton: hmm that looks pretty easy, thanks
05:33 PM rmu: just put that in the crontab
05:41 PM jthornton: lol nothing is ever that simple
06:24 PM ChunkyPuffs: sensille, if you have a problem with adaptive clearing let me know
06:24 PM ChunkyPuffs: the guy who made adaptive clearing a thing in f360 goes to my makerspace
06:24 PM ChunkyPuffs: Julian Todd
06:25 PM ChunkyPuffs: I'll ask him what the solution m ight be
07:29 PM skunkworks: heh - I might have the linux thing down... Finally figured out how to turn off the dedicated video card on a resume...
