Vibrations in draw
Posted: Wed Dec 16, 2020
Good day
I built my own 7ft x 6ft CO2 laser machine and I have a problem, I put a pen trace on it and it seems to make the drawings with vibrations, I have checked the mechanics and it seems to be stiff, the linear guides are well oiled and the belts are taut. It seems that my problem is in the control, I am using a Ruida RDC6445G CNC
Due to the size of the machine, I am using two motors for the Y axis. I duplicated the signals from the CNC to connect the two drives. I think that may be one of the problems.
Another possible problem is the configuration of the accelerations. I read in the manual that there is a parameter “turning acceleration” but I cannot find this option in the menu of the CNC or the software.
I hope you can help me, it is the first time that I have built a machine of this type, I have been trying to solve it for two weeks without success. Attached is the current CNC configuration and photographs of the drawings. Thank you!
