Hi everyone,

I have just got my stepper motors running and have done a test cut with the router. The calibration on the z axis seemed fine, but x and y, the project was smaller than expected but in proportion. I re-calibrated both x and y, then rechecked the amount of travel and had to calibrate again. After a couple more test cuts, the x axis is better but the y is still out.

I am using M542H controllers, which I set the dip switches to a recommended setting from this forum, but I can't remember which post it was, but it has made the motors run quieter than on the settings I had them.

I think the calibration problem is related to the the settings on the controllers. Could someone explain the steps, velocity, acceleration etc in Mach3 and the relationship to dip switch settings. I thought I understood some of this but I seem to be confusing myself even more.

I am using 16mm chineese ball screws on all axes and x and y seem very slow when jogging manualy compared to before I calibrated x,y and z.

Hope someone can help, thanks in advance

Jim
