By supports Mach4, it means it has a Mach4 plugin.

Most Mach4 motion controllers only partially support Mach4. Meaning they don't support all of Mach4's features.

Hi,
a quick email to CNCDrive will clear it up.

I have sent an email to them.
Days ago I also posted the same information on their support forum, but so far, they haven't bothered to release my post.

I am having the same issue:

"System does not jog correctly when backlash setting is non-zero in Mach.  This affects all axis.

Backlash adjustment is applied after each jog even though direction has not changed.  Sometimes, the stepper goes the wrong direction, and often the jog amount is wrong.  For instance a .01 jog may go .01, or may go something less.  This happens whether the jog was done from the pc jog button, or the pendant, so I believe the pendant is not the problem.

Smaller jog increments result in more erratic behavior, especially when the jog amount is less than the backlash setting (which in my case is set to .003"."

I have submitted a post that links to a video showing my experience:

Any help about why a setting of any non-zero backlash amount causes spurious behavior when jogging would be greatly appreciated.

I am engaged in a lathe project. I have had this running on Mach 3 with a UC100 controller but a couple of functions did not work successfully and i was advised to go to Mach 4 .

I downloaded and installed Mach 4 hobby and installed the plugin for UC100 in M4 but when I try to run Mach 4 I get an error message to say that the file is not found

Hi,
I am not familiar with the UC100, however all motion controller plugins should be in the Mach4Hobby/Plugins folder.
There you should see the plugin, it will be of type '.M4PW', but also there should be a signature file  of the same name but of type '.sig'.
Are both of those files present?

A newbie jogging question, with Mach 4 and UC100 motion controller. With Mach 4 incremental jogging set at 0.0010 successive clicks of the X+ button produce the following DRO readings:

.6222
.6241
.6232
.6251
.6242 and so on.

This happens with X, Y, and Z sometimes with bigger jumps.

I am thinking this is a settings issue but not sure what.
