Wiring Guide

Before You Start

Make sure your LRS-200-24 110V/230V Switch is in the right orientation.

Important:

We strongly recommend to flash M8P/SB2209 before you install them, check https://mpx-wiki.vercel.app/Firmware-Flash/flash-m8p-v1-ebb (opens in a new tab) or https://mpx-wiki.vercel.app/Firmware-Flash/flash-m8p-v2-ebb (opens in a new tab) (Depending on your M8P version)

This usually saves you 2 hours or more.

Z Chain:

300mm = 25 links, 350mm = 28 links.

You may have to remove a few links according to your build size.

Layout

Use 3M 5952 Tape to mount PVC trunkings.

We recommend to clean the area to be bonded with alcohol or IPA (Isopropyl Alcohol).

Our PSU mounting is different from the official one. Please refer to the Print Guide for instructions.

Notice the SSR direction.

⚠️

Note:

The default wires are tinned, solder cold flows/creeps under the load and can become a fire-hazard.

You can crimp it with a pin terminal or cut them off and use bare wire instead.

Disco Wiring

You need to use the modified Z_belt_cover STL file. Check our print guide.

If you are using MPX Ultra Z Belt it also works.

Notice the wire label on the cable of both ends. The cable is directional.

The side labeled DIN is the IN port, the cable from M8P should go in DIN side.

M8P V2

If you have the M8P V2.0, you need to connect the Disco in a daisy chain configuration, as M8P V2 only has one RGB port.

The long cable still from M8P, then goes into the DIN side of the first stick, then another cable plugged from the DOUT of the first stick into the DIN of the second stick.

Use extrusion covers to hide wires.

They can also be used to hide B stepper wires.

There's some glue on the NTC100K thermistor's connector, it may interfere with the CW2. In this case, you can try to remove some glue or cut a small gap there.

Optional Printed Parts

BIGTREETECH has a modified CW2 main_body and cable_door printed parts, they can make the wiring of SB2209 more presentable.
