I have a laser with a Ruida 633xg controller. I am getting the Hard Limit Prot random error when trying to run a job.
This happened at random positions on the bed. I can run the same job twice and the error will occur at different positions. Bed is 1300 x 900 and the error can trigger anywhere on the bed.
Tested so far
Limit switch diagnosis - nothing showing on the panel as activated - Is there a way of watching the limit switches on the panel during cutting ?
Changed X limit switch - No change
Watched Limit switches during cutting - no activation at the point at which the error occurs.
Looking for suggestions - Software / Hardware ?
