Upgrading Mk3S => Mk3S+, can't load filament and X axis length error?

Hi All, I've printed lots of things through my Mk3S and it has been very reliable. I upgraded it with the Mk3S+ upgrade kit, and getting back to first print has been more trouble than I expected.

Self test errors out with X-axis length error. And yet, manually driving the print head full left to full right works fine in settings. So I'm trying to figure out why *that* test seems to fail (improvement idea: go ahead and test the other axes if one fails?) Prior to running self test I ran Z calibrate and that works fine. It hits all 9 test points and doesn't complain. As a result this error is annoying but I don't think it is fatal.

The second problem is that I can't load filament. Basically the E-axis stepper doesn't seem to be operating.  This wasn't too surprising when I opened up the electronics and it wasn't plugged in, but I then plugged it in and it still doesn't seem to get power.

I'm particularly annoyed because I felt I really nailed the flexwrap stuff and the wiring from the E-axis to the Einsy is really clean! I am not looking forward to opening that up again so if there are some other tests first, I'd like to figure that out.

One note, I did *not* replace the existing Filament sensor wiring (although I did replace the filament sensor) as the filament sensors are "the same" (according to the assembly manual, just improved) this seemed like a reasonable choice. I think I'm going to go back and check that too.

Did you check to see if the filament sensor is working? you can check this on the LCD screen by going to SETTINGS-FILAMENT SENSOR. A "0" means the sensor is not sensing any filament  and a "1" indicates the sensor is seeing the filament.

Yeah, that was one of my first checks after I posted as I only recalled that I hadn't replaced the filament sensor cable. It is working fine.

I then went to settings, pre-heated the hotend for PETG and then to the Extruder settings to manually run the extruder. That seemed to work which was interesting, so I went back to load filament and then that started working. So I'm wondering if there is a firmware bug I'm chasing (the printer seems to have everything hooked up as it should), I was able to do a first layer calibrate and now I'm doing a test print. It looks like the first layer came out so fingers crossed it is back in business.

I would still like to figure out what is going on with the X axis self test that fails.
