I bought a Rumba board and decided to give the Repetier firmware a shot on my newly built Lulzbot TK-0 after using Sprinter for the past year on two other Prusaprinters. I've been able to get the X and Y axes moving in both direction, the extruder moves only backwards, and I cannot get the endstops to respond at all. I figure I can solve the extruder issue but for the life of me, I cannot get my endstops working. They are mechanical. I have tried all combination of pins on the endstops and on the board. One combination actually turned the board off. Anybody have suggestions? Thanks.

Changing the endstops per you post above (high on Trigger) and making the Always check Endstops= True solved my endstop issues.

Thanks for walking me through this.

Thank you for your help on this, I appreciate it.

I have a 30 amp 12 volt power supply that I bought on eBay, same as the other two printers that I have built. I will twist the endstop wiring tonight to try to stop any stray signals coming from them. and make the "always check endstops setting and invert the settings..]]> roygpa Repetier Fri, 22 Feb 2013 08:03:41 -0500 https://reprap.org/forum/read.php?267,185900,186683#msg-186683 https://reprap.org/forum/read.php?267,185900,186683#msg-186683 In the default settings he end stops are only used for homing and z every time going down. There is an option to changüe this, something like always check endstops, which you can set to true.

My printer for the rumba board is not ready yet, so i can't say anything about stability, but often instabilities come from problems with the psu espeially with atx psus, if they have no 5v load to stabilize.]]> repetier Repetier Fri, 22 Feb 2013 03:09:18 -0500 https://reprap.org/forum/read.php?267,185900,186640#msg-186640 https://reprap.org/forum/read.php?267,185900,186640#msg-186640

The Rumba board also seems unstable with all endstops connected and constantly disconnects from the computer, then it is very difficult to re-connect.

Been there, done that, won't do it again.

Thank you for your help, repetier.
