The DROs only show the axes that are defined. You might create a User DRO with the Screen Editor.

We prefer hard wired MPGs connected directly to KFLOP for guaranteed real-time response. But KMotionCNC does support a wired/wireless Gamepad. See here . Otherwise you would need to write your own KMotionCNC code to support such a device. The code for the Gamepad is in CKMotionCNCDlg::DoJoyStick()

If an axis in the Coordinate System takes 4 seconds to stop then KMotion requires more lookahead than this to be able to expect to have enough data to always be able to stop. So you might set the buffer time to 6 seconds. Or what might be better is to reduce the max velocity before including the axi...

Thanks for posting back. We will fix this in the next Version.

I don't exactly follow that. Is it the Y axis or Z axis that has a following error?

Do you have the M6 configured as Exec/wait/Sync? When a program moves things around behind the Interpreter's back it must be told to re-sync to the new position before continuing.

Hi Tim, I created a patch for Version 5.4.0 with an option to allow changing offsets with a Job Active. KMotionCNC.exe Copy to the \KMotion\Release folder PC_DSP.h Copy to the \DSP_KFLOP folder Add a PC_COMM_ALLOW_SET_AXIS_W_JOBACTIVE command before setting z in the Tool Change Program like this: if...

Hi Tim, I see the problem. We intentionally block changes to the Fixture Offsets while GCode is executing. If we had checked the return code from DoPCFloat we would have known that it failed. I was running the Tool Change program from KMotion rather than KMotionCNC so GCode wasn't involved so it wor...

Hi Tim, This is fighting us every step of the way 🫤 Just to double check, the Z counts/inch in KMotionCNC is 10000 correct? Please post/attach latest programs. “Resetting the DRO” is really computing a G92 offset (there is an option to use the fixture offset instead) such that the current position i...

Hi Thomas, In that case you should be able to us the Z axis Dest as the absolute Z machine position assuming you don't have any GCode offsets for Z. if (ch2->Dest <= 0.0) ... Its not exactly clear how you wish to transition between modes or use the MPG. Possibly when reaching 0, stop, switch to rela...

It looks like the gain is off by about 1.4%

A lead screw pitch of 5mm vs 0.2in would be 1.6% difference.
