Have spent alot of time trying to retune the motors and trying to run it at different speeds, but that hasn't fixed the problem..
We are able to get it run alot smoother by pulling the acceleration and velocity speeds in the motor tuning right back, but in doing this the machine is forced to run so slowly that the cutter is burning the wood. We are using Vexta drives and stepper motors and for the life of us can't get them to run efficiently and smoothly.
The feedrate itself, is still all over the show and during short arc movements the machine shakes and vibrates really violently. As it is trying to decelerate down to zero then accelerate back up to max feedrate in a short space of time.
We have been doing some feedrate tests and we can get it to work really well and smoothly on jog moves but as soon as you run g-code the feedrate accelerates and decelerates at the end of everyline went through and triple checked that constant velocity is set, but this seems to make no difference.
Almost feels as though I have ticked and unticked everything to exhaust all other possibilities and not sure what else I can do
