Edit: why on Earth use ramps instead of Ulticontroller but keep the little display? No gain here. At all. And an expensivr move to boot.by dintid - Firmware - mainstream and related support
You got it working, which is the main thing here. Not really your job to think about the multimeter. That's the seller's job really. One lesson here is to unplug all unneeded hardware when dealing with troublesome issues, in order to limit the numbers of failurepoints. I really thought you were only doing this with just 1 driver, or I would have said it previously.. but that leads to: assumptionby dintid - RAMPS Electronics

I'm not really particularily good at vref and voltage readings, so afraid I can't use the data to do any kind of Diagnostics. You have tried using say X driver on Z? Also try remove all drivers except Z.by dintid - RAMPS Electronics
Quotechz420 Okay, my multimeter leads have screw on caps around the probes, so it was super easy to just unscrew them, stick a small wire with a crimp connector on the other end in, and just screw the cap back on. So, sticking the ground on a GND pin and just going around probing all the 5v pins, I was reading 4.95V on all of them, except for the "servo" section, 0.00 on all of them, but I thinkby dintid - RAMPS Electronics
Quotechz420 I have it mounted directly to the acrylic frame. The pins are contacting the acrylic, I was told that was fine. I took a multimeter to my PSU leads and I'm getting exactly 12.30V across the board. Probably one of the most consistent PSUs I've ever tested. What else can I possibly do? I'm totally at a loss.

If you can get your hands on a 12v wall wart or something you should be fine. As long as you don't try heating up the heated bed, 1map for ramps should be plenty to test z-axis.

Quotechz420 I've tried 3 different cables with no success. I've tried different ports both regular and USB 3.0.

When I Google the "Commands Waiting" they all talk about bad USB driver. Have you tried a different computer and/or just a different USB cable? Have you tried using a different hos program than Repetier? Try downloading and see if you have more luck with that one.. I use it to fault-find and test on my printers. Have you tried both sets of pins for the Z motor? IF you end up buying somethingby dintid - RAMPS Electronics
Try setting the steps to the same for Z as X and see if the motor can move. If the microstepping is wildly out of whack in regards to steps, then it can cause the motor to not Work. Regarding bad psu: It could be issue, but really hard to remote diagnose... it does not seem probable the problem is in the other Electronics parts as you have had everything replaced several times.. bad 5v shouldn'by dintid - RAMPS Electronics
I do not know correct step/mm for your machine. Having it defined incorrectly ca result in no movements. You say 2 interesting things: You can make the axis move if you depress the endstop. Previously you said it read as open when not depressed and triggered when pressed. If the axis can move in 1 direction when you trigger the endstop it means you have the movement logic configured wrong. Seby dintid - RAMPS Electronics
Quotechz420 Thanks for your suggestion. I made the small change in the firmware to disable the max endstops, and running M119 gives me the result I expect, only showing "triggered" when I press the endstops manually. I have also tried swapping out to a spare endstop for the Z. Is it actually possible for me to have received 3 broken boards in a row? That are specifically broken in moving the Z aby dintid - RAMPS Electronics
Quotechz420 Thanks for the reply, I flashed the firmware you linked and, aside from the axes homing in the wrong direction now, there's no change. My Z still wont respond. "n Commands Waiting" Have you checked z-endstop status? If it is triggered for some reason the motor is not going to move. If you use repetier host software you also need to specify your printer in the GUI. Mostly important iby dintid - RAMPS Electronics
QuoteChris-Aus3D The main problem you'll run into is that the servo pins are PWM-capable, while the pins in the AUX-1 header are not. You can still use them to control a fan extender, but you'll only be able to set them to on or off, nothing in between. Pins D0 and D1 may be the same pins used for serial communication with the PC, although I'm not entirely sure. If they are, you won't be ableby dintid - RAMPS Electronics
Asking this to be sure before making a potentially silly/costly mistake. I'm using MightyFan on the servo pins but have need of some additional controls and planned on using a plain old Fan Extended I used previously.

Quotefriarfish Dintid, Thanks for the info. I had cruised E3D recently and didn't twig they had the 'couples. Just need to read up on plugging in the amp/controller. Is it simply PnP or time to go code diving. Andrew If you use Marlin, then it is plug and play pretty much. You need to do the physical wiring of course, which is a 5v,gnd and signal from an AUX port on RAmps to the amplifier boardby dintid - RAMPS Electronics
Arduino/ramps IS your printer. Or at least the brains of it. It is highly unlikely that the frame, motors and wires has been damaged, but if the Arduino is dead, you need a new one and install new firmware on it as well. It sounds odd that bending t0 caused hat much damage. Try dismounting ramps and power up arduino with dc power. See if blinks as it should and measure 5v on it.by dintid - RAMPS Electronics

You need an amplifier board connected to the aux pins of ramps. Maybe look at pt100 sensors as well if they fit in your hotend. They are sort of the new thermocouples. E3D sell it all.
