HELP!: Mach4 3481 jogs in inches when "set"(?) to mm
« on: December 11, 2017, 12:09:29 AM »
Hi, I recently updated to 3481 and now when I jog an increment while in G21 mode, it moves in 'inches' instead of 'mm'.  ex: pressing X+ button with jog increment is set at 0.01 => moves the X from 0.00 mm to 0.2516 mm on the display.
 
I can't figure out how to make it work the way it did before I upgraded.... which is: 1 press on the +x button with jogincrement at 0.01 mm moves the axes from  0.00 mm -> 0.01 mm

I'm sorry if this is a stupid question answered hundreds of times  in other threads. I did do a quick search,  but wasn't able to  find this discussed much, but I'm totally dead in water at the moment (in fact, looking for the old installer file to downgrade). Also totally possible I'm doing something bonehead, schooling welcome.

Hi,
on the Configure/Mach/General page there are two setting; 'Machine Setup Units' and 'Units Mode', I presume you've set both to metric?

I too have seen this with 3481, though in my case it happens intermittently. I can confirm that both config settings are at metric, and I have also checked that both default units and current units are metric immediately prior to the API call for jogging.

This is a serious error and I have no idea whether Mach4 or the plugin (CSMIO-IP/A in my case) is responsible.

In my case,  the MACHINE SETUP UNITS is INCHES (and it was set that way before, too)  and the UNITS mode is MM.  I have been happily using this in the previous build  (since i originally configured and calibrated the machine in inches, but do most of my modeling and run in metric). 

Another oddity that I've noticed is that the JOG slider no longer reads in 1-100%, but now it reads in what appears to be actuals mm/min move speeds.   [EG: the lowest number I can select on the slider is 24.5 on the jog slider].. weird 


Thanks, glad to hear I'm not the only one.

Update:  I found this text in the release notes for 3390

> From Version 2.0.3247 (4/1/2017) to 2.0.3390 (5/9/2017)
> Correct incremental jogging for machines that start in G21 (mm)


Since i still had the original (3390) installer lying around, I downgraded, and the issue went away.
That tells me that it was likely a regression of the fix in a build after 3390.  Hopefully someone who can fix this reads this, and it helps chase it down.


3390    OK
3481    ISSUE PRESENT
3485    ISSUE PRESENT  (found this version on the ftp page)


PS:
Did a little exploration and Can document a similar bug, which happens in reverse.  If you have your machine fully set up as metric (Setup units =  mm  and units mode = mm ) then I was able to repeat the issue by running a G20 command to set the machine to inch readout mode.  Then running the inc jog functions were adding mm increments to an inch display, and JOG rate % slider switched from 1-100 to ~ 0 - 3.9

Excellent work. I will go back to 3390 and see if that fixes the issue. As it is intermittent, it's impossible to guarantee that it will never happen, so it's just a matter of building confidence over time..

I have seen similar effects with 3481 to those you describe if I have metric setup units but issue a G20 command.
