I redid my system

Ah- I can check that and test. I did have to move the sled to get under and its possible.

The chain was off by 2 links. But that did not fix it of course.

Ok some one give me the steps to fully restarting from scratch? I think I am wasting more time chasing rabbits than if I started over from scratch.

So would this work to restart me with blank slate?

Wipe eeprom, wipe positional data, upload driver, go thru first calibration and measure chains out etc, then run the holey program twice in row.

Starting with a clean slate I can take what I learned from this discussion and try again.

no, you would still have the bad calibration from the errors that induced. I’m
seriously impressed that the result was an accurate square, even if it was not
straight.

I think wiping positional data is redundant after a full wipe.

you don’t go through a normal calibration and then a holey one, you go through
the steps to measure out the chains, and then you do the holey calibration.

this time, make sure you mark the links that are at the 12 o’clock position when
you finish feeding out the chains, before you do the ‘move to center’

I think that is probably the best option

You shouldn’t have to run the calibration twice. You should start with something that it’s close, by measuring all dimensions by hand. Then the calibration should change things only a mm or so.
