Not accurate at high speed
« on: October 07, 2011, 08:04:28 AM »
Hi, i have made myself a CNC-router to cut in wood. It has a rapid of 2500mm/min. The problem is that if i try to cut at these speeds it makes a the sharp edges of my object round. It doesn't reach the corners of my project... I can hear that the steppers isn't loosing steps, they sound just fine. If i cut at lets say 500mm/min, it reaches the edges everytime. Is there a parameter in mach3 that is set wrong or are my acceleration to low? I just thought mach3 took the acceleration in consideration when cutting?

I can't quite figure this one out on my own, and my guess is that it's just a simple thing that some of you bright minds know everything about :)

Regards Nic
