Y and Z won't move back or down, respectively
Hi, I'm very new to 3d printing and have recently finished building my MK2.
After my build there were a few leveling issues and while i printed the prusa logo and it came out fairly well, other more complicated prints (Tree Frog and Batman logo) had issues.
While trying to troubleshoot the printing issues I ran into in issue where the Z-axis and Y-axis do no want to move down or back(into negative numbers). I ran the self test and it is returning errors on Endstop Z. I checked all cables and cannot find any of them that are pinched and rechecked all connections are inserted fully into RAMBo.
Anything else I can try, I've contacted the support team but have yet to hear back.
Thanks,

Re: Y and Z won't move back or down, respectively
The printer will never allow to move into negative numbers. The smallest coordinates are [0,0,0]. When you power the printer on, it sets current coordinates to [0,0,0] that's why you can't move left/back/down until you do auto home (G28 gcode command), which sets [0,0,0] to the position where is should be.
The other problem is your failed selftest. Can you make a video of all selftest process, so we can exactly see what the printer does and what the LCD says?
Re: Y and Z won't move back or down, respectively
Endstop Z is the PINDA probe, perhaps it is too high or it moved a little while you were working on the printer?
- Make sure there is a red light on the probe
- The red light will turn off when the probe is close enough to one of the reference points (the first reference point acts as the Z endstop)
If your probe never triggers, you need to lower it. If it's not receiving power then you need to check the connections.

Thanks for the information on the PINDA being the Z endstop, after some testing I noticed the PINDA is no longer lighting up and any calibration causes the nozzle to hit in to the bed. connections are correct but it looks like the issue might be with the cable right as it bends right behind the extruder. May need a replacement.
Thanks for the info.
