Z endstop and bltouch ?
im using the G29 cmd and want to have a removable bltouch
is that posible ?
for example i use the bltouchto create a level map on det sd card then i remove it
next time when i start the print it will use the z endstop to find zero ?
the BLtouch will be lower /closer to the bed so when the BL is attached then it will hit before the Z endstop
Yes you can do that. Use an endstop switch for Z homing, and the bltouch for G29 S0 bed probing. Then you can load the height map subsequently using G29 S1.
However, a bltouch is a bit complicated as a removable probe, you could use a simple microswitch instead.
