Welcome to the SeeMeCNC Community

A little help please.

Built my Rostock Max Ver 2 over the last week or so. Fun project and everything was going exactly as indicated in the build manual up to Page 223, Initial Function Tests.

When inputting the M119 code in the G-Code window of Repetier to see if the Stop Limit switches are functioning, I get : x_max:H y_max:H z_max:H instead of "L"'s I cannot change the values by depressing a switch and re-running the M119 code, everything stays static at H H H....

The instructions state that I should check my wiring, which I have done. I believe it is correct. I used the Arduino ver 1.6.1 to compile, am using the Repetier Host V1.0.6

Is there something simple I missed? This seems like it should be one of the easiest pieces to get to work (its a switch!) I have continuity between the connector and the switch until it is closed which breaks the circuit. I attached a couple photos. Any help would be appreciated.

Thanks in advance,

I think you have them hooked up incorrectly on the connector side. Looking at the RAMBo docs, simple switches should be hooked between Sig and -, you have them hooked up via Sig and + http://reprap.org/wiki/File:Rambo1-2-conn-main.jpg

Looking at the manual it agrees with the drawing.

Agreed. The connectors aren't wired correctly. Pretty sure you're supposed to have pins in positions 1 and 2 on the connectors.

Thank you both!

You are correct, I screwed that up. Not sure how, but very easy to correct. I appreciate the extra eyes...

I'll correct tomorrow and move on! Thanks again,

Stew

Thank you for the clear problem statement and pictures. Makes diagnosing thins much easier.

Exactly why a fresh set of eyes is helpful sometimes! Glad it is working now.

Just wanted to say "Thanks" again. Corrected the misplaced pins on the X Y & Z end stop wiring and not another problem. Smooth sailing though a little tedious in the adjustment phase. I have now printed my fan shrouds and I am really excited about how awesome this printer turned out to be! Looking forward to many many hours of printing! Thanks to those who answered so quickly!
