Mach3 under Vista / Mach 3 and Taig Micromill inaccurate

« on: April 29, 2013, 06:34:41 AM »

I have entered all the motor tuning sections of Mach 3 as per instructions from the internet and information booklet provided. I can't get the axis to be correct with measurements. They are out a lot. Only moving about 40% of DRO movement. The calibration setting does not help. I can make the said changes and it is still very inaccurate. Changing the velocity and acceleration is also changing the distance the axis will travel. I have a Taig micromill 2000 and have set the motor tuning parts in inches to 8000 steps/25 Velocity/5 acceleration/5 step pulse/5 dir pulse. Increasing the steps from 8000 to 16000 is not doubling the distance travelled. I have tried several things and looked up as much as I can, but to no avail. If anyone can help me it would be greatly appreciated.
