Re: PINDA probe, live Z calibration, Z-offset and temperature

is the workaround in the first post still being used by people?


hi and welcome,
at least I'm still using it.

There still will be some offset between ABS and PLA (and, if other materials with vastly different print temperatures come, they will likely have a different offset yet), but with this workaround this offset is consistent from print to print and does not need adjusting for second (third) print in a row.

The (constant) offset is caused by thermal expansion of the print head, which stabilizes a few minutes after heating the extruder.

It also helps to tie the vertical vanes in the printead air exit grid with a zip-tie - the head can split at this place and this moves the PINDA probe a bit (relative to extruder). A zip-tie will reduce flex of the print-head halves.

Edit: attach zip-tie here:

Wow. After three months someone noticed that issue at github. The solution will be any year now.

Can't say I'm impressed with the support level, but that's a lesson for me to learn.
