The Mysterious Disappearaing Endstop

mjm9669

So I have been a long time forum user of all kinds.  However, this is the first time I haven't been able to find any older posts that match my problem.  I am totally out of Ideas.  I built a Kossel Delta printer last month and I have been very happy with it.  After some miner set backs I managed to calibrate my printer and make a few simple objects.  happy ever after right?  Well it would have been but I had to try and tinker with it.  The auto bed function never worked properly when ever I tried to run the program it would returned an error message "Error: Cpos X square". Which was annoying but ultimately not a big deal.  I tried changing my "#define DISTORTION_CORRECTION" from 0 to 1.  I uploaded the new settings to my Arduino without any issues.  When I homed my printer for the first time the X tower crashed into its endstop.  I undid the changes I made and upload the same configuration as I had before but the printer still crashed into the x endstop.  When the x endstop is triggered it turns on a red LED as it always has.  So i know the endstop is getting power from the Arduino.  I manually checked the signal out put using m119 and the X endstop returned L regardless of weather it was being triggered.  All the other endstops including the z probe functioned properly.  At this point I figured it must be a hardware issue so I replaced the endstop and the wiring with no effect.  I also tried re-downloaded Repetier host with no effect.  After almost a month I'm starting to lose hope.  My only other thought is may be it is a problem in my code.  Sometimes if I stare at something long enough I miss the obvious problem.  Without being able to home my printer I an dead in the water.  If anyone has any advise it would be appreciated.  My H configuration if too long to post.  Will add it in the comments.

Repetier

You seem to have an electronic endstop, so maybe you need to disable endstop pullups. If pullup is stronger then signal this can override any signal from endstop. Only confusing I find is that you say only x endstop has the problem. But maybe they are all near the edge just on the other side.

Your "Error: Cpos X square" comes from a test point that is outside reachable area. Echeck in eeprom your probing position and make them near your towers.

After a long absence I have taken my delta printer out of the closet in hopes of getting it running again. To answer your question from many months ago yes I do have electronic endstops.  I disabled the x_max pullup.  Now when I try to home my printer the X stepper does not move at all.  The Z and Y steppers continue to work properly.  After running an m119 command my repetier software now tells me that my X endstop is triggered whether the switch is open or closed.  Any suggestions?  I will try to get back to you a little faster this time.
