View Full Version : x axis is jumping

06-02-2010, 06:03 PM
When I select the x axis there is a slight hum comming from the motor. When I apply movement the motor starts to jump vilolently until I am forced to hit the e-stop. I have tried to reverse the leads and then I get an error so that is not it. When it happens I don't get any errors in mach 3. Any sudgestions? Thanks Scott
