Help with config.g 6hc, tool distribution board and 1LC
-
I think I have the system figured out ... once you know how it's done it seems easy
I got the two fans working (after figuring out that one of the new fans was dead) and will be playing with the heater and temp sensor next - hopefully it will be just as straight forward. -
Well looks like I hit a snag. I got the fans, heater, temp sensor defined and connected to the various IO pins but I can't seem to figure out how to set up the extruder motor.
I am guessing here:M584 E121.6 ; set the 6th motor as an extruder and use the motor from expansion card 121
M569 P6 S1 ; set the 6th driver to go forward
M906 E800 ; set extruder drive current to 800 maBut really don't know what I need to do to specify that the motor driver on the 1LC board with the address 121 is an extruder and is motor driver #6

Not exactly. When you target a new board, the extruder count goes back to 0. So it would be 121.0

This would be your tool definition.
Setting up an example config in the config tool might be a good idea to get the syntax.
For example, here's a Duet 3 with four toolboards and 4 tools:

I went through the exact same issue with my new tool board about two weeks ago. The definition line ended up as:
M584 X1 Y2 Z3:4:5 E121.0 -

This would be your tool definition.
Thank you VERY much. I will take a bit of time to wrap my mind around the config.g but I think it answers all the questions !
Thanks kb58 too.
-
Keep in mind I left the default CAN addresses for the tool boards. It would be a good idea to change them. There is some guidance on that here: https://duet3d.dozuki.com/Wiki/CAN_connection
This is because if you ever replaced a toolboard, etc it would have the default address and you might get a conflict.
-
@phaedrux, that is a great point. I had not thought about that.
Just to confirm that I understand your point correctly, you are suggesting that I not use address 121 on any of the configured tool boards .... correct ? -
Correct. Based on this: https://duet3d.dozuki.com/Wiki/CAN_connection#Section_CAN_addresses you would want to use addresses in the 20-39 range

ae5853f1-7f19-47e0-9632-7a5499a005a8-4toolboardsconfig.json 4toolboardsconfig.json
Here's the config.json for that 4 tool setup in case you wanted to load it up in the config tool and customize it a bit more to your setup. I left all the defaults and didn't get fancy.

Well isn't that interesting - I read that wiki page numerous times and managed to gloss over that section each and every time!
Thanks again ! -
