Small Prints After HE280 Upgrade

[ehisforadam]

My machine is a bit of a Frankenstein's monster...I have a V1 machine with the V2 arms, original laser cut cheep skates, and the HE280. The HE280 is mounted on the V2 end effector platform. Everything is up and running okay, it auto levels and prints fine. It definitely needs some other adjustments, but the big problem I'm running into is prints are coming out undersized in X-Y. I've printed a few 20x20 calibration cubes and they always end up closer to 19mm. I've tried changing the delta arm lengths, and carriage offsets, and other parameters to what they are in older firmware, but it's not improved the X-Y size. Are there any other settings I might be missing that need to be changed? Is there anything in the auto-calibration that should be updated? Thanks!

The X-Y scale is a function of arm length. If you changed arm length and don't see an effect, your value was not getting saved.

I've posted in several threads on how to do this:

Great! Thanks. I'll take a look.
