Leveling

Start printing ANY print and go to advanced - adjust Z to zero - Cancel print
Go to Settings and disable motors
with nozzle resting on .2mm spacer (Frosted shim stock) (blue tool is 0.1mm) - adjust the prox sensor to rest on a 1mm block.
Adjust prox sensor to just turn on (multi-turn pot)
On start up
Put 2 100mm blocks under horizontal bars to chassis base and adjust bar to good fit manually - hold left drive in place and go to move - move Z up
Go to LEVELING_MENU
Wait for home
.2mm spacer should just slide under nozzle - Tweak prox sensor Repeat home until adjust Z until just touches - Home button should repeat homing
Go to the LEVELING_AUX sub menu - Adjust the 4 corners to just touch nozzle to .2mm spacer
Run auto level - check numbers -
Try a print - if the first layer is too thin - you can adjust it during the print.

Installing Micro Swiss all metal hotend kit

There is no pressing reason to uninstall the old nozzle - but you probably want to remove the filament before starting.

When reinstalling - use high quality heat sink compound on thermistor and heater.

Nozzle has a 3.3 N-M torque [30In-lb] Tighten when hot!

Nozzle is 0.4mm

Rewiring

The system does not have the proper wires for motion - best to replace with silicone insulated super fine stranded wire. (BNTECHGO)

Powersupply is a Mean-Well RSP-500-24 (550W 24V)

The heaters are the only thing with much current - The nozzle uses about 2A@24V (about 50W) - so 22 or even 24Gauge should be OK. The Bed is supposed to be 250W so a little over 10A - so I would go with 18 Gauge wire.
