Hi LightBurn Community,
I need some help understanding how position is established in rotary mode. My current setup is an Omtech 80w with an RDC6445S controller. Ive added stepper driver and utilize the U axis for my rotary. Everything works fine with the rotary except every once and awhile, I get a “Frame Overscale, Work paused” error. For reference ive successfully run a handful of jobs on the rotary so from a functional standpoint everything is working as it should be.
My workflow is to power on the machine, allow homing of the x and y axis, position the gantry where id like over the rotary, enable rotary mode, set my user origin, send file to the machine, and run. Before sending the file, I ensure my job origin is set to user origin mode and I align my artwork as close to the green origin indicator as close as possible.
I guess my question is, if I am using the dedicated U axis for rotary, why does the controller still thing I am out of bounds? My Y axis displays its position at 10000 when in rotary mode and the x is within the bounds of the coordinate system. Am i missing something in regards to where the U axis thinks it is? Thanks!
To do this, jog away from your home corner, press the reset button on your controller and then press the ‘Esc’ key on the control panel as soon as you notice the homing start.
Now your soft limits will be no longer active, so try not to jog X or Y axis axis too far.
After finishing with the rotary, disable Rotary in LightBurn, then press the Reset button and let the machine home normally.
If the firmware version of your RDC6445 allows (Edit>Get Controller Info, 15.01.30+ is best), it’s possible to choose between Y and U for ‘Rotating Axis’ using RDWorks 8.01.60 e.g.
Note: Before you change anything, always click on ‘Read’ to read in the Ruida controller’s current settings, and it’s good practice to ‘Save’ a backup of those original settings. After you make the change and ‘Write’ to update the controller… wait a few seconds, then ‘Read’ again to verify the new setting was uploaded successfully.
