Now I just gotta figure out how to adjust the heat and flow settings.

I gotta wonder why those wires were just torn though, kinda weird..

Thanks again,

I don't remember it even trying to calibrate by touching the right side before going too far to the left but it's possible I just didn't notice.

Thanks a lot man, I'll going to attempt to fix the wires now, I'll let you know how it goes.

The switch on the SD4 is on the extruder carriage and is the only switch on the carriage.  Usually 2 black wires and they go into the braided harness down to the board.  I would start at the switch and if those wires look good look at the board for a loose plug.

Found it... they appear to be ripped apart and tucked under the heat-sync... So I guess that explains something. It looks like the end switch only triggers when it hits the right side of its limit though and my problem is that it's going too far left, I don't see how those could be related but it's definitely weird that the wires are just cut/ripped.

My guess is your X-axis endstop switch is unplugged or otherwise not functioning properly.

Where can I see a picture of where that is and what it looks like?

When I use that, it moves the extruder about half an inch to the left, it doesn't center on any location, I wonder if that's a clue to what's happening.. it seems like it's just adding in left movements in between everything it does.

Edit: But yeah, I'll compare mine. Thanks a lot guys. I'll be back in a few after I check.

just a hunch  in printer settings/printer tab this time, at the very bottom are the  Invert direction in controls boxes checked?

So if this isn't the issue there is most likely an end stop not functioning properly.
