+# Tuning the printer
+1. PID_CALIBRATE HEATER=heater_bed TARGET=100
+   1. This will take ~10min
+   2. Once this is done, use SAVE_CONFIG
+2. Enter M106 S64 <- this will turn on the part cooling fan at 25%
+3. Enter PID_CALIBRATE HEATER=extruder TARGET=245
+   1. Once this is done, use SAVE_CONFIG
+4. Next up take a ruler and try to get gantry as even as possible on both sides.
+   1. Make sure the nozzle will clear the bed
+   2. G28
+   3. Press QGL to start automatic leveling
+      1. The probe will measure distance in all four corners and adjust is each corner automatically until all corners are adjusted. It will try up to five times before giving up.
+      2. Tolerance allowed is 0.00750, if you did your assembly correctly, it should be no problem to beat.
+5. Extruder
+   1. Add bowden to the the toolhead
+   2. Try to extrude filament, configuration is already tuned for you
+6. Z-Endstop calibration
+   1. Once the chamber has heated up (set extruder to 240, heat bed to 100)
+   2. Add a sheet of paper between the bed and toolhead
+   3. Run Z_ENDSTOP_CALIBRATE 
+      1. Then run TESTZ Z=-1 untill the nozzle is close to the paper
+      2. If you go too far, run a TESTZ Z=1
+      3. Once you are close, switch to TESTZ Z=-0.1
+      4. Do this until you feel a drag on the paper when moving it
+      5. Remove the paper
+      6. Beacuse we did this hot, we need to do one more TESTZ Z=-0.1
+      7. ACCEPT
+      8. SAVE_CONFIG
+      9. The nozzle bed offset is done for now.
+
+
+For configuring MainsailOS from SSH, ener SUDO raspi-config. From there you can join your device to WiFi should you choose to do so.
