I’m using a 60W CO2 laser with a Ruida 644XG controller and LightBurn (v1.7.04). I’m having an issue when engraving cups with handles using a rotary device. After the job finishes, the rotary device rotates, which causes the handle of the cup to hit the laser head.
I’ve checked the Device Settings in LightBurn but couldn’t find an option to stop the rotary from moving at the end of the job. I’ve also ensured the origin and rotary setup seem correct.
How can I prevent the rotary device from rotating after the job is done to avoid this collision?
Any advice or suggestions would be greatly appreciated!
If the RDV6442G manual is relevant (which is not guaranteed ), look for the Back Position setting in Other Parameters, down near the bottom of Vendor Settings in the Machine Settings list:
Back Position: The origin (the relative origin) and the machine’s absolute origin can be selected. This parameter decides the parking position of laser head after each work.
The manual’s wording is never exactly what appears in the settings, but ought to be vaguely similar.
You probably must jog the laser head to the desired spot and poke the Origin button on the display to set what they call the “relative origin”.
If there’s nothing close, upload screenshots of the settings so we can look over your shoulder.
Finding the right chunk of doc requires concerted digging and some pointers, but you’ll remember seeing something else that will come in handy two months from now.
