Rotary not working through Lightburn but ok with RDworks

[LaserCuttingPro (Neil)]

All connected up ok as runs with RD works fine.

Connected to Y axis, when I use the manual Y axis buttons on controller the rotary rotates ok, and the engraving works fine in RD

When I click test in LB, instead of the Y axis rotating the X axis moves about 40mm left. no matter what I change, it will not rotate the Y axis. I have been told that my controller is not compatible with LB, but it works perfectly with LB on flat bed stuff. My controller is RDC320. Is an older one and the company I bought the laser from said it will only work with laserworksv5, which is more basic than my 40 year old sinclair lol

Just wanted to check if this is a known issue before I spend ££ on a new controller

Did a quick search here and found the following:

Rotary lightburn setup, trouble Ruida controller

Have you set the steps per rotation properly for the rotary? If you haven’t done that, then the rotary may be moving too slowly or too quickly for the motor, either losing steps, or not moving enough. When you switch back to normal mode, you need to make sure to switch the Rotary Enable button back off again as well. Do you have a ‘generic’ Ruida controller, or one from ThunderLaser? Your profile does not specify which machine you have, and you don’t mention the controller model either - som…

Rotary device setup

You only need to set this once. It’s a setting stored in the controller itself. I should ask - do you know which model of controller you have? There are older RDC320 models that don’t work this way and I don’t properly support them yet.

The support provided is limited and the requests for supporting using some magic remains low. Based on that, it is unlikely we will invest the additional effort required to develop a magic solution for this control model.
