I'm getting a couple errors related to macros already existing:

"gcode command SYNC_STARTUP already registered"

The "Toolchange" macro throws the same error. What might be the problem?

[3DCoded]

Thank you. I've updated DynamicMacros to attempt to resolve this error. Please run the following commands in SSH to update it:

cd ~/DynamicMacros
git pull
sh install.sh
sudo service klipper restart

If the error persists, please upload a new klippy.log as a file (not copy and paste). If it's too large to upload, you can compress it in a zip file.

[k4j98]

Yes, sorry - I didn't see the attach option before.

Still throwing an error. Here's the new log

klippy (1).log
.

[3DCoded]

Looking at the log, it looks like the first error is gone. I updated DynamicMacros to attempt to fix this new error as well. To install it, run in SSH:

cd ~/DynamicMacros
git pull
sh install.sh
sudo service klipper restart

[k4j98]

I think that did it; no more config related errors.

I'm only getting "3ms unable to connect", which is because I don't have it connected yet. lol

Thanks so much for you quick responses!

[3DCoded]

No problem! Let me know if you need any more help setting up the 3MS.

[k4j98]

Is the amount of retraction during a tool change adjustable beyond 200mm?

EDIT: NVM - I found the setting. Looking good.

[3DCoded]

You can set your load_ and unload_distances as high as you want. However, if you want faster and slightly quieter toolchanges, you should increase your step_size 3MS setting to the highest of the two distances. If you run into Extrude move too long errors, you can set your printer's max_extrude_only_distance to your 3MS's step_size + 1.

[k4j98]

Another generalized question: do you have any intention of incorporating a belay sensor?

[3DCoded]

I don't have a Belay sensor, but you should be able to configure one for the 3MS with:

[belay my_belay]
extruder_type: extruder_stepper
extruder_stepper_name: 3ms0
sensor_pin: ^PA0
multiplier_high: 1.05
multiplier_low: 0.95
debug_level: 1

On each toolchange, you can add this to your slicer's tool change G-code:

BELAY_SET_STEPPER STEPPER=3ms{next_extruder}
