Y axis length failure
I know this has been talked about ad naseum, but I have done everything possible and have contacted support. I may have to send the unit back but I want to try to avoid doing that.
I just reload the firmware and then also looked at the output of the Arduino that runs the printer. I wondered if there is any clue in the output that might help me fix the unit rather than sending it back. Here is the output. Can anyone help?

That just tells you that the Y axis is shorter than expected..
Check the cable bundle is not hitting a wall at the rear.
Check the Y belt is free to move (with power off move it by hand, is it smooth? Does it reach both limits?)
Clean and lubricate the smooth rods.
Check the belt tension, check the Y idler is free to move and not clogged with filament debris.
Let us know how you get on.
Cheerio,

What number should it be and what are the units, mm?
RE: Y axis length failure
I think your answer was the clue.
I make a camera mount that connects at the side of the y axis frame. Apparently it had moved or changed its position over time and was interfering with the stop limit of the Y bed movement to the front. I took it off and it passed belt test. Self test is no passing all the X Y Z position tests.
I can't thank you enough for the clue.
