General Mach Discussion / Re: Move, give up sync
« on: January 05, 2016, 11:33:27 AM »
Thanks Tweakie,

I just gave up and did a windows restore to the 31st of December.  That cured it. 

Now I am just back to the original issues I had posted in "Taig Mill Questions" about the backlash settings, CV and trying to increase machining speed.

General Mach Discussion / Move, give up sync
« on: January 05, 2016, 10:18:31 AM »
Hey all,

Keep getting a "move, give up sync" message in the status bar when auto tool zeroing, or attempting to get auto tool zero to work. 

What does this message mean?

General Mach Discussion / Tool Probing Issue
« on: January 04, 2016, 07:12:16 PM »
What in this script would cause Z to only move +0.25"  In Diagnostics, the Digitize LED turns on when touchplate is grounded and turn off when the touchplate is not.  It's like Mach3 is skipping down to the "FinalMove" line.

Was in the process of installing V.062 and this did not work.  So went back to V.066 and even though I transferred/saved the copied Mill.xml from and to the Mach folder, I still had to manually reconfigure and calibrate everything.  This is the last thing that I need to get working and not really sure why it isn't following the script.

FeedCurrent = GetOemDRO(818)    'Get the current settings, OEM DROs (818)=Feedrate DRO
ZCurrent = GetOemDro(802)   'OEM DROs (802)=Z DRO
GageH = GetOEMDRO(1001)   'OEMDRO(1001)=Gage Block Height
ZNew = ZCurrent - 20      'probe down 20 mm

Code "G90F20"         'slow feed rate to 20 MM/MIN
Rem Code "G4 P0.5"         'Pause 1 second to give time to position probe plate
Code "G31 Z" &ZNew
While IsMoving()
Sleep(10)
Wend
Call SetDro (2,GageH)      'DRO(2)=Z DRO

FinalMove = GageH + .25
Code  "G0 Z" &FinalMove
Code "F" &FeedCurrent        'restore starting feed rate       



Thanks, 

Pete

No, the stray voltage issue was no the problem with the intermittent MDI operation.  Will backtrack Mach3 version to .062 when I get a chance, hopefully, that will fix it.

Gary,

Hooked the multimeter up to the power supply, am getting a solid 47.8V out of it while running the mill, so no problem as far as power.

General Mach Discussion / Taig Mill Questions
« on: January 03, 2016, 05:56:48 PM »
Hey all,

In the process of fine tuning and working out some issues with my Taig mill.  Running a PC with a 3.16Ghz processor with 4Gig RAM, connected to a Leafboy77 (http://leafboy77.com/index.php/en/) USB motion board, connected to 3 each 2m542 stepper motor controllers, then connected to the 3 570oz/in stepper motors.  Also installed is a 48VDC power supply. 

I am curious as to the speed at which other owners have their Taig mills running.  With backlash enabled, I am pretty much limited to 12in/min.  Without backlash enabled I can jog at 25.  I really would like to be able to machine close to that speed with backlash enabled.  I only have backlash compensation enabled for Y at .003".  Is backlash compensation a inhibiting factor?

Questions are, I have tried to follow the 50/50/50 rule talked about before with regard to backlash compensation.  Took the middle of the two extremes of .050 and .005 for a setting of .0275 for the shuttle speed.  Backlash speed set at 50%, and motor speed set at 15ipm.  Again, the mill without backlash compensation enabled and speed set higher can traverse at about 23-25ipm.  Again, I would like to be able to approach that with the backlash enabled. Assumed that with these motors, they would have the torque to do nearly anything I needed. 

Also dealing with another abnormality.  20% of the time when jogging X and Y, X will sometimes slow and chatter, as if losing steps.  I can let go of the Y arrow key and X will still chatter.  I can also toggle off and on the Y arrow keys and stop and start Y at will all the while X is still chattering.  Sometimes the roles are reversed, so it doesn't only affect X.  I can run X and Y separately and never have a problem.  Why does it happen when they are operated together sometimes?  It can be a real pain especially when the part is zeroed and I am just moving the spindle out of the way or changing tools or moving to begin a tool touch.  If I hear the steps being lost, I have to backtrack, waste time and reinstall the edge finder and rezero. 

Would running CV help the issue?  Also what effect does the kernel speed have on mill operation?

Ultimately, I would like to get rid of the stepping issue, and increase my machining speed. 

Let me know what you all think.

Late last night I was working on the control box, houses the power supply, interface board and stepper controllers.  I got a little shock and discovered 68VAC between the case of the controller box and ground when the USB cable was unplugged.  Found the ground prong broken on the power cord plug. So the USB cable shielding was carrying the faulted ground condition to ground thru the PC.  Anyway, ran out of time and so hopefully this will be the fix for the MDI intermittent issues.

Hey Ger21,

Thanks for the quick reply. 

Yeah, I am going to install .062 when the machine frees up. 

I am using http://leafboy77.com/index.php/en/ for the interface board.  Have it on 2 other machines and is bullet proof.  I'll contact the dealer if need be, I gave them bloody H377 with the first board (completely different board, had it's share of different glitches)

General Mach Discussion / MDI glitches
« on: January 02, 2016, 02:04:10 PM »
Hey all.

Having an intermittent issue.  When using the MDI screen I will often move the 3 axis' for various reasons, I use this screen a lot.  For example, I will touch off the tool on the top of rough stock, 0 Z and then jog up and off the top of the stock to the side, type in Z-.020, start the spindle and face top of said stock.  Move off the end, type Z-.040 and face again.  Or another thing I like to do before hitting "start" when running a program is to type G0 X0 Y0 Z0 and the tool moves to the origin, just want to double check everything first.  Then I will jog Z up and then click start. 

In both common situations, I will type in the command and hit enter.  The computer will ding, (meaning to me the computer has registered the command), but nothing happens.  I then have to close Mach3, reopen and then MDI will then work, sometimes 10 times, sometimes only 1 or 2 times, then it will lock up and I again have to restart Mach3. 

I don't believe it to be a keyboard issue.  Typing the code and hitting enter all work, confirmed by the MDI line and the enter key "ding". 
Rerouted all the cables for the mouse, keyboard and USB cable away from the steppers, controller box, power supply etc. 
Grounded the PC to the controller box. 
Using version .066 (considering installing a previous version)

Let me know what you think

General Mach Discussion / Re: Backlash when enabled, kills everything.
« on: October 30, 2015, 04:17:19 PM »
Its been a few days and finally have the mill running with backlash compensation enabled.  Ended up being the plugin for the interface card was incorrect.  Took four or five tries with Automation Technologies tech support to get one that works.  But got it running today.  I now have to study up and see about running with exact stop or constant velocity and the pros and cons of each. 

All in all the fix for this backlash compensation enabled deal was getting the correct driver.
