Then it all went to crap. Yesterday morning, as I was posting I hit "Home all" and heard rude noises from my Tornado. It seemed that a wire had broken to Z0 and it became obvious that I was crimping too tightly. I re-crimped the ends and got a "short message" in phase A. Phase A??? Did they mean Z0? I ohmed out the cable and found no shorts. In the next hour or so, I figured out that being wired in serially, meant I had to divide and conquer, removing B's lead screw and jumping the header as if she wasn't there. It turned out that the 42-40 servo on phase A had an internal short, so I replaced the motor with a 42-34 and reinstalled B.
Somewhere in all of this, I rewired a cable backward and when I went to re-terminate, and then followed that sequence for all the stepper motor cables. I was uber frustrated, wasn't having fun, and had plenty of other stuff to do. When I got too frustrated, I simply did something else or moped a bit and came back to it. Late in the day, I finally arrived at this...
I figured it out after a lot of trial and error and then relying on the following two documents, which I can now easily find since I'm posting them here...
The kicker? After all of that, the Z motors were going bassackwards. So I learned how to edit the config.g file to change that. I just hit "Home all" again after 24 hours have passed, and it all worked just fine. Le sigh. I probably don't need to match the z motors any closer than I have, but I just ordered 2 42-38 motors. I want the extra ooohmp because that direct drive extruder is a bit heftier than the stock hot end.
Oh what a tangled web we weave when we try to upgrade our printer 3D. -
