CR 10S Pro


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


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.
