Description
Companion to MarlinFirmware/Marlin#28690, which adds a compile-time check that the SCARA/TPARA home position lies inside
X/Y_MIN_POS..X/Y_MAX_POS.The stock examples keep
X/Y_MIN_POS 0, but their home position is computed from the home angles and is outside that range:Y_MIN_POS -60Y_MIN_POS -190X_MIN_POS -80Nothing else changes: the bed is still 0..
X/Y_BED_SIZE.Requirements
Marlin#28690. Until it merges these limits are harmless; the examples build with or without it.
Benefits
The examples keep building once the check lands.
Testing. I did not build against these files directly. The same three limit values were applied as overrides to the Marlin CI configs (
mega2560extconfig-08 and config-09,mega2560config-05), and those build with the new check on every commit of #28690.Related Issues
