Fun and games. Trying to make mill factional

[terry1956]

Hi, so today I tried to set the motor tuning in mach3. First setting the motors to as high a speed that they could take, then backing off. All good so far. Motors turn at a good rate, and sound ok. Then I try to set the steps and all hell starts to happen. First I set Mach3 up to run in mm. then I try to set the steps. First I input 10mm movement and the machine bed moves near the end stop and I need to stop the machine. I reduce the number of steps in the motor tuning page of Mach3 to 2000 steps from the 15600 it had input before. Then go back to set up the movement of the x axis. Input 20mm, the machine moves 37mm. Input 37mm set axis. Now the x axis moves at a crawl. What is going on. Thanks.
