This is most definitely an unfinished draft!

1. Config Checks

Since the config file supports a couple hardware configurations, check the following:

Toolchanger Lock Motor

If you are using the StepperOnline Toolchanger Lock Motor (pn: 14HS13-0804S-PG5), the settings for that motor should look like this:

M92 U11.515                             ; Steps/deg for U from (200 * 4 * 5.1818)/360
M906 U900 I60                           ; StepperOnline U motor current and idle motor percentage. Do not lower idle current.

If you are using the LDO Toolchanger Lock Motor (pn: LDO-28STH32-0674APG14(JVU)), the settings for that motor should look like this:

M92 U30.578                             ; Steps/deg for U from (200 * 4 * 13.76)/360
M906 U670 I60                           ; LDO U motor current and idle motor percentage. Do not lower idle current.

Number of Extruders

The Config file assumes a Jubilee setup with two extruders. If you start with only one extruder physically connected to your machine, you will encounter weird error messages from the Duet Web Control Interface. To remove these error messages, comment out all lines in the config related to the second extruder.

2. Checking Direction of Movement

The Jubilee coordinate system is defined like this:

X and Y are oriented such that 0,0 is in the corner of the usable (300x300) build plate region. The choice of origin is such that you can change the parking post locations of tools without having to work with negative values.

Z increases when the bed gets farther away from the XY gantry. If the Z axis seems confusing, imagine it from the bed's perspective. Here, the bed is fixed and the XY frame moves up and down. When Z increases, the XY frame and attached tool get further away. When Z decreases, the XY frame and attached tool get closer. At Z=0, the nozzle tip is touching the bed.

To make sure you wired your stepper motors correctly, we will "baby-step" your stepper motors 1mm in the positive X, Y, and Z directions.

To enable movement before homing, type this:

M564 H0 S0



TODO: finish writing this or actually write a script with GIFs to show the expected output....

3. Checking Limit Switches

Before homing, we must ensure that the machine limit switches are plugged in.

On a Duet 2

The Duet2 features one LED per endstop. Pushing the limit switch, should cause these lights to turn off until the switch is released.

GIF Here

Check the X, Y, Z, and E0 (technically the U) axis switches now by pressing them with your hand and ensuring that the corresponding lights blink.
