Useful trick on tanks: hook a vacuum cleaner to the top port and pull some vacuum! I've pulled a 1/2" NPT fitting out of a full hydraulic tank that way. It was under about 2 feet of oil! It went "glug glug" when I pulled it, hardly anything came out.

Got it sort of wired but the X motor is... trembling. It moves but in a very loud and stuttery manner. Wonder what the cause of that could be. I guess I aught to check continuity on the cables.
S. Heslop:
Continuity seems okay. I switched out the stepper driver and that didn't do anything. My best guess is that either the stepper motor itself is damaged or the approximately 3 meter long cable is too much for it. I'll try exchanging the motor for the extruder motor I suppose.
Edit: Motor is fine, tried hooking the Y motor to the X output and that runs fine. The problem must be with the cable. I guess I could try measuring resistances but I hope the issue isn't just the length.
awemawson:
3 meters shouldn't be too much Simon, I have well over that on some runs on my CNC Plasma Table. Are the motors 6 wire that you have to interlink, and maybe the linking has gone astray?
S. Heslop:
I wasn't sure what you meant but I did switch two of the pins inside the plug around after the first issues. I... didn't consider to check the other leads but it turns out the way it was with the middle two wires flipped was correct. I'm not sure what the first problem was. Maybe something stupid like I had the connector set over a pin.
Everything seems to work now but the Z axis. Sharing the one controller it doesn't have the torque to lift the Z axis. Is there any way to configure marlin to make use of that spare 2nd extruder controller?
Edit: Forget that last one, just found the right combo of things to google search. Also thanks for the help Andrew.
