I have built a delta 3d printer.with Ir-sensor
I have problems with auto level .
After uploaded marlin 1.1.8
First probes seemed OK, next time i'm auto level it does not go to 0, it triggers about 22mm from the hotbed.

Can not get in any way make it trigger with an IR sensor? the sensor is working fine !

Hi There,

Just a thought, but are you printing over a glass bed? It sounds like the IR sensor is triggering 22mm above the bed? Try putting a piece of masking tape where the bed levelling probe first touches down and see if that helps.

Cheers

Tim

Which type of IR sensor?

Large delta printer [miscsolutions.wordpress.com], E3D tool changer, Robotdigg SCARA printer, Crane Quad and Ormerod
