Yeah, probably the case. Wish it would turn the Single Block LED off when it turns off Single Block!!

I'll try the manual way tomorrow and see. Never thought about doing that, doh!!

Small hijack. Hood, have you ever run your feed hold brain with single block on? If I do it, when I pot back up and cycle start activates, the control is no longer in single block even though the Single Block LED is still lit!! Have to exit single block and go back. Just curious if you've ever seen that. I've tried on PP and SS, mostly I use SS.

CVI MachStdMill (MSM) / Error, artcode 904
« on: September 27, 2010, 09:25:26 AM »
MSM Beta 11, Mach 3.043.022.

Every once in a while, seemingly randomly, upon exit of Mach I get an error box with something about artcode 904, attempt to recover, YES/NO. It doesn't do it every time and not all that often, but I haven't been able to determine what I might have been doing that might cause it. It happens on my milling machine computer and on a test computer both setup the same way except test computer doesn't have a machine hooked up. I don't remember seeing this ever on 1024 screens, hence the post here.

Any idea what artcode 904 is and what might should look for?

Well, I lowered my acceleration by 50% and the problem went away!! As always, Brian, you KNEW!! I guess I should have been watching the Gecko fault LED, but I NEVER THOUGHT of acceleration.

Thanks for that.

Now, how DOES one determine acceleration? I've been running with my accels at 7 for a long time. Suddenly it goes berserk! I set it to 3 for Z and the peck drilling works great. I don't actually notice much difference. Is there a procedure for determining optimum acceleration values? I have Keling servo motors on all three axes, KL34-180-90s, the big bruisers, a 72 volt PS, Gecko 320X/320 drives. CUI AMT-102 encoders at 400 line count. X and Y 24000 Steps per, Z 19200 Steps per. X/Y 100 IPM, could go to 150, Z 40 IPM, could go 50, Z is counterweighted knee on BP clone. Is determining accel a trial and error thing and I just happened to stumble on the break point, or is there a "scientific method"?

Seems odd that you can see the DRO change but the axis is not moving.. The Positions on the screen are from the index registers in the SS. The index registers are set by the pulses that go OUT of the SS. So this tells us that the Pulses "should" have been sent from the SS to the axis drive. is there a chance that you  drive faulted due to over acceleration and that we have an accel problem rather then a Drilling problem? I would lower your Z axis acceleration by 50% and see if you still have the problem.

Thanks
Brian


I'll certainly try that, and I can look at the G320 led and see if it faults during this peck cycle.

But how would one explain it working on PP and not SS? Do they handle the acceleration differently somehow? Motor tuning is identical between my profiles, PP and SS. I don't get a drive fault any other time moving the Z, but pecking is definately a test!!

Brian,
       there are no MPG'S enabled, i don't have an MPG.

                                                                        Mick.


I don't know what MPG Mode is either, but perhaps if we told Mick how to check if he is IN MPG Mode. I seem to remember about a "mode" where you could step thru the program with the MPG, but I've never done it or even looked into it. Maybe Mick somehow got into "MPG Mode".

Where can it get the SS v16bd plugin?  I seem to have missed that.

I don't remember but it was in a forum thread about the SS and noise, perhaps on the Mach3 Yahoo group or Geckodrive group? Greg posted it there but I've never seen it anywhere else, like on the Warp9 website. Not sure if it fixes anything as I took the advice in that same thread and mounted my SS inside my computer case at the same time.

I don't know if it's proper forum ettiquitte to post it here as it's not "official", or I would.

If you want to email me at thosj1 at gmail dot com, I'd email it to you.

Went hunting, found it here:  http://groups.yahoo.com/group/mach1mach2cnc/message/121135

Yes, all my testing was with Mach3 v3.043.022.

Your chart is correct.

I'll have to see if I'm up to testing with the first dev rev!! When I get thru 4 hours of this I'm convinced I'm done screwing around but then I sleep on it and my mind is reeling and I go back down there and do it all again!! Good thing I don't have to make money with Mach3 and my milling machine!!

I suppose to test 3.043.006 I'd have to rename the Mach3 directory and install 006 from scratch. I could copy a profile in and that wouldn't be too bad. Hmmm....might not take much to try that!!!

I could also look thru my saved Mach3 directories from the past and see if I have one with 040 lockdown setup for my new PMDX hardware, but I don't think so. But one more run thru a complete new profile wouldn't be that big a deal either seeing as I am so damn good at it now! I almost have my Ports & Pins setup memorized and I do have my motor tuning settings memorized. I can set Config/General Config pretty much without looking, too!

At any cost, I think you're right assuming it's a dev rev thing as I drilled with G73/G83 all along with lockdown versions and 1024 screens for 18 months without any issues. I am NOT sure I've drilled any since rev devs and MSM unless I did it while on PP and never saw it with SS. I've done so much profile switching and PP/SS switching since this all began I can't remember it all! Then to add to the confusion I went from CNC4PC C23 BOB to PMDX and went from Gecko G320 to G320X during this time. If I ain't careful I'll approach 'expert' status one of these days.

Back to the original issue!

Dave, as you suspected, you and MSM are off the hook ;) Today I tediously created all new profiles for MSM and 1024 cloned from Mach3Mill and entered all my info (I am getting good at this!). My problem with G73/G83 is present on MSM and 1024. Once in a while a hole will peck drill OK, but 98% of the time it does NOT.

Here's what I observe. Drilling starts, moves to X/Y, comes to Z.1, starts the first peck, stops feeding at some seemingly random spot but the DRO says it's still moving, retracts when DRO says it's at the right spot, retracts seemingly the right amount, .1 in my case, starts next peck, same thing, DRO says it't moving when it's not, it may move some again seemingly random amount before stopping with DRO still going. It seems to start feeding, stops while Mach thinks it is still moving, leading to Z being OFF location now. I tried drilling holes .5 deep, .2 pecks, then .1 pecks. It's worse with .1 pecks as it almost never feeds. By the end of 3 holes the Z is off by about an inch and a half!! Thankfully PLUS!!

I switched to PP, pecking works just as smoothly and consistantly as possible, over and over, all aftrernoon, MSM or 1024.

So, it seems to be an SS/Mach3 issue, again. I did try both SS plugins, 16bd and 15ogx2, no difference. If anyone thinks it might be something with my setup, please advise, but seeing as it works on PP and NOT on SS, I'm thinking my setup/mechanical stuff is OK, and it HAS been OK for a year or so.

I'm not sure if I should take this somewhere else or let it simmer here as long as Brian AND Greg have made appearances. I'll leave that up to them and you, Dave.

Mick,

Can you post a bit of your gcode with the G83/G73, just for a look-see? Your issue is WAY different from mine for sure.
