Hi, i just bought a new laser 4x8 feet. this laser made with servo motor and rack/pigon. it use a rudia 6332m dsp controleur nad i use it with lightnurn. my toruble is whne i try to make round at fast speed 50mm/sec the round come ovale in diagonal. when the round is ccw the oval is from right to left and when the round is cutted cw the diagonal is from left to right. i tried to change offset setting and acceleration setting but always get similar result. when i try to cut a 15 or 20mm/s it very better. i think teh trouble sould be teh pid in the servo drive itself. is it posible to try to ajust pid on servo drive to have more acceleration?
