I think we are ready to integrate one more Holey Calibration step improvement into the firmware: the chain tension calculation and chain stretch compensation.
I propopse to do it so that users get immediate vertical scale improvement of their center upper workspace. That would at least improve the standard calibration results.
The proposed implementaiton adds 4 slots into the EEPROM table: sled weight and chain stretch would have default values, plus two reserved slots. Bumping EEPROM table to version 6.
This way, a default value is applied, and macros of the type $4X=YY would allow advanced users to tune manually. Then it would be ready for a later update GC to offer GUI based adjustments.
I prepared a firmware version for review before triggering a pull request. I will test it in the coming days. (Arduino IDE compiles fine)
It is based on the current firmware and integrates these specific items from Joshua’s proposal.
Please review and comment.
