Adding support for the enraged rabbit carrot feeder (ERCF)

@danzaywer said in Adding support for the enraged rabbit carrot feeder (ERCF):
In prisaslicer or superslicer start gcode put T[current_extruder]
I'd meant the filament loaded into a particular tool would be out of sync, not the tool number, that aspect is already handled. The problem is that any T0 T1, etc don't know what filament is loaded. There's no way to know it from start gcode. RRF can guess based on previous state (filament M701 gcode during filament changes from the slicer) but it cannot know if filament was swapped out of the tool.

@pfn when you change filament in tool you simply click on tool name in DWC interface and select "change filament". At this point firmware know what filament is present into tool until you swap it with a new one, also after reboot... DWC do all the magic... I fear my English is not so good to explain but trust me : Duet do it!

@pfn whit my configuration I can slice a file to print with T2 in with I have petg, after print I change T2 filament to pla and reprint same file with pla temps , only issue I have is fan speed, I'm working on it but , I can set max speed in m703 but don't know how tell to firmware to handle bridging situation. My intent is to have gcode independent from filament loaded in tool.

I understand this, but I have always forgotten to do this, I heavily rely on the slicer to set filament for me. Why set it in multiple places, it's not an optimal workflow
-
@pfn I change slicer often, not printer, so I prefer that is the printer to handle things. Another reason is that if I have a file sliced I can print it in any material without reslice it. I name sliced files with tools involved in it.

Other reason to let the printer manage temps:- slicers put temps command after Tx command so is not possible to manage temps prior to return to print position after change
- prusaslicer/superslicer have bed temps for firstlayer and other layers but put into gcode the instruction relative to actual selected material so if you have, as exemple, ABS and PETG print with ABS fist layer:110, ABS other:90, PETG first layer: 80, PETG other:70, first object of list in ABS (the one with high temps) then slicer set first layer temp to 110, change to second tool , set second layer temp to 70 and ABS detaches...

Hi, is there a working solution for ERCF? The GitHub at the start of this thread seems abandoned
It will be great to stick to RRF & DWC, but if it's not supported in future it might be a reason to switch to klipper
-
@Inlinebrother I was working on a refreshed version of pfn's config earlier this year. But then I managed to formate the wrong drive when doing a clean Windows install and lost all that work (+ alot of other projects).
After that i kinda dropped off for a bit, I still got all my notes etc. anf plan to take it up again in the future. But seeing how much TLC the klipper addons have been getting the last year it's not something one person can keep up with porting over to RRF unless it's his full time job.

@Inlinebrother I asked @pfn on the RRF Discord server (https://discord.gg/uS97Qs7) if he was still using it. His reply:
I haven't updated it to latest and whatnot, it did kinda work before
I don't have a filament sensor in the toolhead, it's entirely driven by the ercf encoder
so because of the way filament monitors work on rrf, if you have a can-fd toolboard, you need to run the filament monitor from the ercf to the toolboardIan

I'm working on it with an Duet2 Ethernet and RRF.
For startingpoint I usedhttps://github.com/pfn/EnragedRabbitOnRRF.
Assambly is already finished, loading and unloading is working.
First testprint still waiting for time unfortunataly.
