Delta printer bed levelling
October 29, 2021 06:37AM
Hello I have just finished building a delta printer running RRF wifi on a SKR 1.4Turbo board and now want to install a bed levelling probe but am not sure which is the best to use. The printer has a 300mm glasss bed. Recommendations would be very welcome.

For delta printers, nozzle contact probes are best. This is because it is very hard to get the geometry of a delta so accurate that the effector remains perfectly level as it moves in the XY plane, and any tilting will change the relative height between the nozzle and an offset probe.

Types of nozzle contact probe include:

- Duet3D Smart Effector
- FSRs (force sensitive resistors) or piezos mounted in the bed supports
- Piezo or microswitch in the hot end mounting

Thanks for that dc42, I think I will try a Piezo unit first
