Prusa MK2S Pinda Probe Cooler

thingiverse

I noticed when printing ABS the heated bed has a large effect on the accuracy of the Pinda probe and it changes your z height, when cooling this manually by blowing on it, it fixed the problem, so I quickly threw this Pinda cooler together which screws directly onto the original mounting point for the Prusa I3 MK2S standard print cooler. Personally, I print ABS without cooling the print so cooling the pinda probe using this attachment at the start of a print worked wonders for me, I get perfectly accurate Z height with this attachment. When using this probe I use Octoprint, which enables me to activate my fan before I press print, if you do not do this then you will need to edit your G-code before you print and ensure the print fan turns on before you home and calibrate z height. Edit: The Gcode you need is "M106 S255" to turn the fan on and "M106 S0" to turn the fan off. In Slic3r there is a section called print settings and under custom Gcode you would put "M106 S255" before G28 (home) and "M106 S0" after the G80 code (mesh bed leveling).
