It’d be helpful to know the Ruida controller, which should be printed on the main box inside the electronics bay: RDC6442 / RDC6445 / KT332N.
That will let us poke at the manual, which is often misleading, and maybe get a little further.
That’s true of all the controller settings, which often trips folks up. The controller determines how fast each motor will spin based on the desired speed, the angle of the vector with respect to the axes, the type of motion (move / vector / engrave), and the various speed limits. You can tell LightBurn to run at any speed you want, but the controller sets the actual speeds.
A recent discussion involved stepper drivers with exotic configuration switches, one of which had been bumped out of position:
Upload pictures of the servo drivers in your machine so we can read the model numbers, find the manuals, and see if something weird is going on.
A nitpicky point of order:
- Speed has units of
mm/s - Acceleration has units of
mm/s², sometimes written asmm/s^2
In a paragraph discussing both speeds & accelerations, hanging the proper units on the numbers helps everybody understand what’s going on.
While I’m pretty sure you mean 3000 mm/s² and 25000 mm/s² as accelerations, we have had discussions where folks sincerely believed because they set the LightBurn layer to a speed of (say) 25000 mm/s the machine would actually do that.
