I have a Monport 100w CO2 with RDC6442G-B. When I use a rotary, I have to use the y axis and if I don’t remember to change the current settings on the stepper driver, it cooks the motor. I bought a stepper driver just for the rotary and tied it into the controllers available U axis. From the control panel, it works fine jogging and the motor does not get hot.
From lightburn, how can I use the U axis for rotary mode? When I open the rotary tab the in lightburn, it has choices for using Y, Z, or A. Z and A are grayed out and not selectable. I poked around in the machine settings screen, but didn’t find anything.
I wish I’d known about the limitation of the 6442G before purchasing. I only saw that it was 4-axis. Didn’t realize U was reserved. I also don’t see any reason why Ruida couldn’t update the firmware to support this just as they did with the 6445G/S.
It could be many things, that model being phased out … or the 42 is an older model and they have moved on … If that’s the case, we’re lucky to have basic bug fixes, let alone any kind of ‘upgraded’ firmware …
It also might be the hardware won’t support it… dsp is kind of a different animal…
Whatever the issue, maybe we should contact LightObject and see if they have any suggestions… I’d like to move mine to an unused axes but the results for a 42 owner seem rather dreary.
