Title: Mach4 incremental jogging problem
Post by: thecncman70 on January 14, 2024, 09:32:02 PM

Posted this in pokeys section also but maybe better suited here, recently installed Mach4(was using Mach3 before) and I'm having a jogging issue using incremental. I'm using a pokeys57cnc board, all latest software versions of mach4/pokeys firmware and plugin. The motors are very jerky and noisy and are missing steps, this is even jogging fairly slow but faster I go worse it gets. Continuous jogging works perfectly fine and running G code files also fine, this is the only issue I have come across. Also all jogging works fine if I switch back to mach3.
I recall a post saying to use an increment that is an even amount of steps, which is kind of hard to do but I tried various values between .001 and .010 without any change.

Here is quick video of issue, I'm open to any suggestions, also leaning towards it being a pokeys issue but its hard to tell.

Did you try it with the jog rate lower than 100%

Yes tried numerous jog rates, had no affect.

Acceleration too high in the motor config?

Tried slowing that right down also, did not help, but wouldn't t that be an issue with continuous jogging also? Keep in mind I can run G-code files with lots of rapids and have no issues. Really the machine works perfect except for this.

What version do U use?
Try to use older version.
I have same problem with version 5 and was open few tickets to Mach4 team and ProLabs, but nothing helps :(
Here few messages about problem: https://www.machsupport.com/forum/index.php?topic=46906.10
This is was few months ago and I do not checked with latest version.

Best Wishes.

I'm using all latest versions of Mach4 and Pokeys plugin, I have a ticket with Pokeys hopefully they can recreate the issue and get to the bottom of it.

But in the mean time I may take your suggestion and try some older versions.
