General Mach Discussion / Strrange sound of stepper motor Mach3

« on: December 22, 2016, 12:14:18 PM »

Hello while I have builded small CNC
could you someone know what could be the source of strange sound of my stepper motors? Its like thud, thud every about 1 second sometimes not even every second.. all three axis. Even if I unmonted the rails and test only motors its the same. I am running on Mach3.
Was thinking maybe too long cables or something in electronic?

Power source 24V 10A
Drivers DM420A
Steppers Nema17

Thank you

General Mach Discussion / How to set a mechanical gap in Mach3

« on: December 05, 2016, 03:41:37 AM »

Hi guys, I am new here.
Have set up Mach3 for first time everything kind off OK. Now I have a gap or loose space on the axis like on the thread so the axis should always go a few steps when changing direction to skip this gap.
Do you know how to set up this in Mach3? Havent find this on net.
Or is there another way to achieve this?

Thank you a lot
