Solved Z-Axis not responding.

Hey all,

It's me again, I have been trying to figure out why my z-axis is still not responding. I wired the endstops into and go to press home and and nothing happens when the z-axis is supposed to home. The x and y axis work perfectly. I've tried flipping the direction of the stepper connections and nothing continues to happen.

 

Nope connected them correctly.

I believe the firmware is the r1+. Here are the pictures of the ramps hookup

So as it sits rested is open. Lifted off reads triggered.

Do it should be normally closed for mine?

So, made a new wiring setup and it's reading the z correctly but still refuses to move. I hear a high pitch static noise though whenever I press home all.

 

Swapping the drivers now, thankfully I bought a bunch to build an extended 3dmax in a month but anyway, swapping driver now.

 

Nope, not the driver and I can turn the z rods with ease.

This is the bootup, not sure if anything seems off about it.

So, I tried every possible mechanical fix and still to cannot seem to get the issue fixed.

ALTHOUGH, with that said, I decided to make an all or nothing move ( quite literally ).

I am currently sitting in front of both my robos and the one this issue started out with is on my right. I swapped a hotend over to get my other printer up and running. They are both now running Marlin 1.1.X that I got in Nov.

Funny thing is.. I know for a fact the printer I swapped the hotend over to ( on my left) would hoe PERFECTLY.
Uploading the new Marlin with the accelerated settings according to this vid, well the lines the vid went over work great but the homing is now screwed up and my only options are:

So, I know now that it wasn't a mechanical issue, at least for my homing problems. I've tried swapping the true/false statements on the home inverting but now all three refuse to home correctly.

They keep homing to their max positions if left false, and when true they studder for maybe 5mm and stop. The wiring and phsyical parts have not been changed or touched other than the hotends.

I'm pretty lost in the woods as to what the issue is... hopefully I'm over looking an easy fix.

Thanks for your patience with me and this issue.

I ruled out the stepper driver, the ramps ( swapped with a board from my parts robo), stepper motor works fine when I plugged it in as my y-axis. the wiring was traced and it's all correct with the videos on how to wire it. Ramps was determined to not be the issue as the problem has now started on my working printer until I uploaded the new firmware.
