Prusa i3 MK2 and BLTouch
Hi, I'm trying to change the PINDA probe with a BLTouch sensor, but I´m having problems porting the BLTouch code from Marlin. And I also tried to put the Marlin firmware on the Prusa, but I'm missing something because I lose the display when I flashed it ... I couldn't found many information about both subjects.
Has anyone succeeded doing this?
Thanks in advance
Re: Prusa i3 MK2 and BLTouch
Sorry for having no answere to your initial question but a question myself.
Why could anyone want to replace the quite cheap (11€) PINDA against something different?
It works quite well, given the print head is away from the bed far enough while preheating
which anyone would want it to be anyway to clean the nozzle before starting the print.
Put that...
G91 ; use relative coordinates
G1 Z2 F5000 ; lift nozzle by 2mm
G90 ; use absolute coordinates
G28 X0 ; home X axis
G1 Y195 ; move Y axis to end position
G1 Z100 F5000 ; lift nozzle by 100mm
in your ending script, whatever slicer you are using to have it "parked" after every print in an appropriate position.
Adjustments could be of need for very high prints so that there will be no collission with the part....

Hi, thanks for the feedback.
I like to use a glass on the bed, and the induction detection of PINDA doesn't work with the glass, so every time I print I have to pause the print after the calibration so I can put the glass on it. With the BLTouch it measures the bed from the top no matter if I put a glass or not.

I'm not sure if we are talking about the same ... in the Prusa firmware the BLTouch code was removed to make space, so first I have to hack the code so the firmware support the BLTouch again (as a Z stop I think) and maybe I have to modify the startup g-code of the slicer as well.
