General Mach Discussion / Having trouble tuning steps per mm

« on: July 15, 2022, 05:05:59 PM »

Hi, i just finished wiring up my machine and im having trouble setting up steps per mm. Im using nema 23 motors with 1/4 microstepping and a 1 revolution to 10mm ballscrew. That should result in 80 steps per mm. if i manually configure theese settings i can increase the speed and the machine moves faster accordingly. However the coordinates are completly wrong. i can move the machine 15cm and it thinks its moving 1mm. If i tune steps per mm form the built in wizard on the settings menu the coordinate system works perfectly, i can move 1mm and the machine moves 1mm. But doing it this way locks me at a painfully slow speed of 80mm/s. if i then try to increase the speed from the motor tuning menu it breaks the coordinate system again. It looks like the coordinate system in mach moves at a constant speed regardless of the actual speed of the machine. I've never used mach before so i'm probably overlooking something. Any help would be appreciated
