=== Auto calibration ===

  * configuration -> delta calibration -> auto -> enter -> wait -> enter
  * configuration -> store

=== z offset ===

Disable software endstops (M211 S0), preheat and with motion z to grab paper: get deltaz (positive or negative, for example 0.3)

  * configuration -> runout sensors -> off
  * temperature -> preheat PLA -> preheat PLA
  * motion -> z
 
adjust probe z-offest adding deltaz:
  * configuration -> probe z-offest -> =**z-offest+deltaz** 

enable software endstops (M211 S1)

store settings

=== z babysteps ===

<code>
M290 Z0.25 ; move up 0.25mm on the Z axis
...
M500 ; store
</code>



==== PID autotune ====


start pid autotune at 220C and 8 cycles
<code>
M303 S220 C8
</code>

wait and
store proposed values with M301
<code>
M301 P13.83 I0.76 D63.18
</code>

save settings
<code>
M500
</code>


==== Thermocouple tuning ====

Get actual extrusor thermocouple from Menu -> About -> Thermistors and from Configuration.h get actual thermistor_xx.h utilized

set hotend to 200C from control and check in terminal ADC value (138.06 in example)
<code>
Recv:  T:200.47 /200.00 (138.06) B:21.64 /0.00 (982.37) @:47 B@:0
