I got it working by adding a G92 X0 and a G92 Y0 after homing each axis in the homeall.g file

Changing it to G1 X+15 Y+40 F3000 does not help. Does the same thing

RE: Start of print rams x/y carriage into frame
I've got it homing ok with each individual axis but homeall is ramming the x. It's the G90 before the y movement just before G30. I'm not sure why it's causing an issue0_1567989799754_homeall.g

RE: Start of print rams x/y carriage into frame
Ok, I was homing in the back right corner. I am using the Z probe as the Z endstop. When I home to the back right corner the probe is over the bed but not when I am at the front left.

Start of print rams x/y carriage into frame
Running a CoreXY printer. I can move and home all the axis using the controls and GCode. But when I upload a print sliced in Slic3r or Cura it heats, it does the homing and then slams into the side of the printer for a minute, then starts printing in the home corner. Like it's moving the Y or X in the wrong direction. I'm just note sure why as it moves fine when I run GCode manually or use the controls from the web interface.
For example, the line below gets me close to the center of the bed when I run it manually, but it's not working when running the gcode. That is lifted straight from the GCode file0_1567983466160_CFFFP_20mm_cube_soft_edges.gcode

RE: Duel Z movement weirdness
OK I see what I was doing wrong I was setting the steps per mm in the config.json only but I needed to update it in the config.g too. That's why none of my changes were making a difference

RE: Duel Z movement weirdness
Does the interpolation to X256 micro-stepping come into play in this calculation? The default 4000 steps per mm was moving too far as well.

RE: Duel Z movement weirdness
@deckingman Thanks, I'll try that. I attempted 400 steps per mm. It was default set to 4000

RE: Duel Z movement weirdness
I figured this out. It was just the weird motor wiring not being the same on both motors so they weren't moving in the correct directions.
Now the Z axis is moving way to much. 10mm is closer to 100. I set the steps per mm to 13 just for kicks but it didn't seem to change anything. I have the z homing at the high end but can only move it down 30mm despite my size being 300mm.

RE: Duel Z movement weirdness
I've tested 3 motors on all the drivers. The only results I can get are a a brief stuttering of movement and then a short to ground message or the same Phase A and B might bot be connected message
-
RE: Duel Z movement weirdness
I think I'm losing my mind. Today, the motor that was working, doesn't. I didn't unplug it or swap cables but it's back to getting the error message that the motor phase a and b may be disconnected. I have tried every possible wiring combonation and I get the same error no matter what. I've tested 3 different motors, same results.
How can I tell which pin is ground and what is voltage? I used a multi-meter to find the pins on the same coils

RE: Duel Z movement weirdness
I'm unsure of the current limit. They are generic nema 17 motors so I would assume the usual 1.5-1.8. It's curious that is started so suddenly with both motors on bot connections.
Edit: I was able to track down my order(I bought the parts over a year ago). These motors were both from Abycubic and were purchased at the same time but appear to have different pinouts.

RE: Duel Z movement weirdness
Well it's stopped working all together now. I just get a motor phase may be disconnected message every time I try

RE: Duel Z movement weirdness
COnfig.g is attached. I haven't lubricated them myself but I can also move it without any resistance manually.

RE: Duel Z movement weirdness
The binding is coming from the weird movement. Why is the left side, moving back up? The axis in the video is level. It's raised as high as it can go and is leveled. Config file is attached. I am using standard G28 Z to do the z homing

Duel Z movement weirdness
I am building a hypercube evolution and just got to the z motors connected. I attempted to run a test of the z homing but it is moving very oddly and causing binding. In the attached video you can see the left side move down, then the right side and then the left moves back up causing the whole thing to bind. I have both motors connected to the standard z connectors on the board. I can move it freely by manually rotating the leadscrews and moves without issue if I remove the leadscrews. Any ideas?
