DTI, jog buttons, then use the tool setup page to set the measured X dimension to zero and update the tool offsets.
The spindle is being given controls via RS485. It doesnt work on power up. Enable the plugin for the VFD, it works but trips (kicks out reset on software). Then disable the VFD plugin, it works without a problem. That said, it spins the wrong way initially then the correct way. The speed inputs also dont seem to work well. Might need to reset this setup and start again.

Any thoughts?
Modbus is the most consistent way to set spindle speed, however it sounds like there may be a bug or two in the scripting. Probably best to post over on the mach forum, as I've never used Modbus directly with Mach.
