I have recently purchased the Cohesion rotary attachment, and set it up for use with LightBurn (currently 0.9.07) and a Chinese red/black machine with a Ruida RDC6442S-B(EC) controller. I used the LightBurn setup procedure on github.
When I attach the rotary to the Y-axis, and switch on “enable rotary” in LightBurn, everything works for a couple of test pieces. After around 15 minutes of use the controller starts shutting down mid-job. When this happens, sometimes the panel blinks white and nothing more happens. Sometimes the controller turns back on but can’t restart the job properly due to the y-axis not being able to home.
The stepper motor feels excessively hot to the touch. I haven’t measured the exact temp yet but I would be burned if I tried to touch it for more than a quick tap with the back of my fingers. Real hot.
When I remove the rotary, and set things back to normal in LightBurn and on the machine, I can engrave normally again.
Are there any known issues with Ruida controllers? I’m not finding anything on this forum from a search or in this section. Some other issue I haven’t considered?
Thanks for your time. I like the design of the rotary, and am looking forward to getting some hours in using it.
