help, shortguide for setup firmware?

Postby mandy » Tue Jan 20, 2015 11:42 am

got to two NC optical endstops(Z+) and (Z-), one nema17 (Z), runs marlin firmware.

mecanic is..
Dia: 8MM
Tr8*8
4 Start
Pitch 2mm
Lead 8mm

trying to run CW but nothing happens... so.. im completly newbie.. my guess is either endstops are messing around and sending stop signals.. or something with the motor or its something else... so.. whats you configuration.h look like? and how should can i calibratate the rod?

thanks for reply.

(Splitting this into two posts since the two issues are completely different, and this way avoids a wall of text)

Alright, now for the tough one. We're going to need a lot more detail than "But nothing happens".

First off (And you'll hate me for this) -- Is everything plugged in? It's possible to connect to CWS over USB, but the motors can't run from that. (Hell, check if your motors are plugged in, too. I've had that happen to me before)

Second question: Is CWS successfully connecting to your board? If not, then you should check out It's written for the Uncia, so some of it may not apply to you, but about halfway down, it starts talking about COM ports. It's important to get both the port number correct and the baudrate ().

If you are successfully connected, but still can't move, it could be due to your endstops. I'd unplug the Z- endstop and see if I can move in either direction (Marlin sometimes locks you up until you've homed).

Again, it's hard to diagnose without more info (And/or photos/screenshots), but hopefully this helped.

ok, uhm, i might have found something why the motor wont work.

every time i turned on the power supply, the green lamp just went black at the power supply, so when i disconnected the power supply from the ramps, removed all electronics and still, it seems that is a short circuit between incoming + and - at 12/5A.

its like 0,1ohm between + and - at 12/5A

uhm... suggestions? or should i bridge 12/11A with the 12/5? (but something tells me that it wont work.

When the axis moves in only one direction, it's usually because the endstop is inverted.
