Makes sense @Brook_Drumm ​ and the link worked fine!!! So that jumper changes the voltage readout??? Does that mean you aren’t using resistors on your inductive sensors???

Or https://printrbot.com/wp-content/uploads/2015/09/Rev-F-Printrboard-Endstop-Setup.pdf.zip

thanks for the pdf, openoffice wont open the .doc file :D.

Downloading!

You bet!

@Brook_Drumm , and what about firmware?, i should disable autobed leveling, but if i disable it i cant compile it, That doesnt happens with stock marlin.

No firmware changes necessary. It can prove… Theoretically, it will be completely flat since the same endstop will hit 3 times in the same place. If bed isn’t totally flat, manual shimming or installing bed leveling adjustment screws will be in order

But @Brook_Drumm does the printer not just assume the bed is level if you don’t have the g29 command in your slicer start sequence??

Im going to test this!!!

You can start by manually setting the tip where you want to start. Just remove any ha command from the slicer settings or gcode… I started printing way back when and never had endstops :wink:

@Brook_Drumm ​ not even a z endstop? ??

No. You can turn off all endstops in firmware but it’s no fun. I recommend endstops though and especially the z sensor
