 ====== new life for the Prusa Mk3S with klipper ======
+**NOTE:** after using the printer with Klipper for a while, i have noticed that its reliablity has gone down, because it no longer has crash detection, a feater I personally find very important. I will revert back to the original Prusa firmware and print speeds for the sake of stability.. I prefer if a long 20 hour Print is reliably done after 20 hours or fails in a recoverable way after 15 or so hours, vs. the print taking only 9 hours but crashing after 8 and leaving me with a huge mess around the extruder and what not to clean up. But of course that's my personal preference.
+===== Klipper on the MK3S =====
 there is a very good [[https://www.youtube.com/watch?v=tamAzV9y1bc&t=355s|video on youtube]] which explains it all. basically a raspberry pi zero w can be added to a prusa mk3s printer and then the klipper firmware can be flashed to control the printer using klipper and therefore enable input shaping which more or less gives you the Mk3.5 upgrade bur for the cost of a raspberry pi zero W and a SD card, roughly 30 CHF in total.

+===== PID Calibration =====
+on the dashbard page of klipper, there is a "Console" box. make sure that the printhead is not touching anything with the nozzle and then run this command:
+  PID_CALIBRATE HEATER=extruder TARGET=170
+it will heat the extruder to 170 degrees celsius and cool it down a bit, then heat again etc. once this is done, the console output will show the pid values. run the
+  SAVE_CONFIG
+command to save these values and reboot klipper.
+now repeat the whole process for the heated printbed:
+  PID_CALIBRATE HEATER=heater_bed TARGET=60
+and dont forget:
+  SAVE_CONFIG
+===== Prusa Slicer Profile =====
+install the Mk3.5 input shaping profile and then save a copy of it, calling it somthing like mk3s klipper or whatever.
+now edit the profile and go to dependencies and detach the profile, then in general switch the G-code flavor to Klipper and disable binary gcode.
+in the custom g-code tab remove everything in all the text boxes and disable "emit temprature commands", now add this in the start and end gcode:
