[Solved][Help] Stepper Problem [Pictures & Video]

Postby nephertiti » Fri Jan 11, 2013 10:47 pm

Hello,

System:

LO DSP
24V PSU
2m542 Step Driver (bought from lightobject)
Nema 17 0.9 deg

Problem:

I wired all things according to LO DSP PDF.
When I open DSP I hear stepper motor sound but my stepper not working. I press stop and try to move my stepper by clicking DSP arrows. It moves a little and stop. When I press longer again it moves little and stop ,after stops I hear stepper sound again but no action(still pressing the button).

Here is wiring pictures(attachments)

Waiting your helps.

Thank you.

Jumper out all limit switches when testing. It probably thinks the limit switch is open.

Glad to hear you figured it out. It looked like normal operation to me.
