Hi,
Ive recently built my second plasma table using servos, my first was using steppers. I have been having trouble reaching the recomended cut speeds in the book for the plasma but have found that when i decrease the acceloration value i can achieve much higher speeds, using the servo configuartor sofware i have i have tuned the servo drives so that the following error is pretty small so i think that is ok but if i reduce the acceloration enough to get the correct cut speeds my accuracy is hopeless, i never encountered this problem with the steppers, is it likely a cv problem or a servo problem, im sure the first response will be asking for more detail about the machine but i thought i should ask a general question and hope for some advice.
Thanks alot
Matt
