Z axis stopend problem

Post by erniehatt » Mon Feb 29, 2016 5:04 am

I am having problems with the Z-max showing triggered when nothing is connected to it, can someone please tell why this should be, have checked across the pins with DMM there is no short. Thanks

how about reverse the endstop direction as the post here shows:

Hello Mark, thanks for the reply.
The link did not explain My problem, so let me see if I can explain it a little better.I have the GT2560 working fairly well at this point, all Axis home to a point where I want them.
The bit I am having problems with is, I am trying to set up an auto bed leveling system, it is an IR Z_probe, which I must say worked extremely well with the original Arduino Ramps boards.
Using the same configuration I did with that, I am not getting the result I expect.
It goes through all the motions but the probe is just going up and down at the X axis, and not moving to the center then to the four corners.
If at this point I run a M119 it is telling me that both the Z axis's are both Triggering, I don't know if this should be, or if there is a definite problem, why it should be so when nothing is connected is the little problem I have with it, can you explain it. Cheers

Hello Mark, thanks for the reply and the link, which didn't seem to answer my problem.
Let's see if I can explain my problem a little clearer.
I have got most things working as I would like, except for this one problem, well I think it's a problem.
I am trying to setup an IR Z_Probe for auto bed leveling, which incidentally worked with the original Arduino Ramps configuration, but for some unknown reason will not with the GT2560 board.
I don't know if this is normal, but both the Z min and max endstops show triggered when entering M119, what makes me think it is a problem is nothing is connected to the Z max pins.
What should be happening is it will on a G28 home to all, it does that, then given the G29 it should move to the center and probe, then probe all for corners, it is not doing that, it is just going up and down in the one spot. got me beat why this should work with one set of boards and cot the GT2560. Not another failed board I hope.

I don't quite know how But I have fixed the problem the board now seems to be working as it should, keeping ten fingers and toes crossed. :D :D
