Title: Stepper moves 1/4 turn then stops
Post by: TOMMYD on August 27, 2010, 05:13:03 PM
I am set up on a test bench.I connected my 1 st stepper motor,configured it in mach3 and everything worked fine.Then I started going thru mach to get familiar with it .I must have pushed a button that I shouldn't have.Now when I push the left or right arrow key (they both act the same but in opposite directions) the shaft turns 1/4 turn then stops,when I release it it turns another 1/4 turn then stops.The shaft is a geared output shaft,7.2-1 ratio,so I guess the motor is actually turning 1.8 rev. before it stops.I did get an over load alarm and had to reset my driver.Can anyone tell me what I should do to correct this and get back to the motor turning properly. I am very new at this! thanks Tommy

Sounds like you have changed to step mode. Press the shift key on your keyboard and on the flyout screen change the Jog mode to constant.
