SAMMYC21 ERCF

@Th0mpy are you using the ERCF sensor under the extruder?

Th0mpy

@jay_s_uk Not at the moment. I am only using the 1/2 bondtech gear in the ERCF itself for confirmation of bowden distance to load the extruder.

I am thinking of adding a sensor in the extruder to simplify, but there is no eloquent way to add a reliable filament sensor (i.e. magnetic filament monitor) to the stealthburner yet. They do have a simple switch sensor but I really don't like the washer approach.

That said, I am playing with the laser filament monitor, which would fit into the stealthburner nicely. It does not, however, work as well with the PET filament. I did contact the manufacturer to get their specs and programming guide for the sensor, but I haven't had time to play with it yet.

@Th0mpy it may be worth looking into https://reprap.org/forum/read.php?424,889788

@oliof Good ole Forest Mimms, I had a few of his books from Radio Shack when I grew up.

I will have to check this out, I was considering something like that but was leaning towards something already manufactured. This is cool!

@oliof
That is cool.
Have you integrated it on RRF?
If so, can you detail it (in a new post)?

Th0mpy

@OwenD Of course! I plan to share what I have this weekend(ish). I'll post a new thread on the subject.

@OwenD I have not built that myself, nor integrated into RRF. I am just reading that section of the venerable reprapforum and sometimes interesting stuff comes up.

@OwenD Did you make a new Post? I am soldering my own canned ercf board now. Can you share the firmware card you used?

OwenD

@VoodooBane
I think you need to ask @Th0mpy
I'm just an onlooker

@Th0mpy

Hey thompy, Do you have any of the boards still? I would like one from you if you do

@Gixxerfast I sourced a bunch of the SMD components myself. However, it looks to be that some components are missing from your Excel document. I didn't think to look for whatever reason before buying components.

The components you did not include in the Excel sheet and what I am missing.
D1, D2
C3, C4, C6
R8, R11, R12, R13, R14, R15, R16, R17, R18, R19

I really hope I am not screwed...

See my screenshot.

@VoodooBane I was actually able to find what the components where in Kicad.

Th0mpy

@VoodooBane Hey there, sorry for the delay. I might have a couple left, let me know if you're still interested.

Th0mpy

@OwenD Haven't touched it in a hot minute, but as I recall that I had a custom firmware to handle the two steppers. Are you still looking for this?

EDIT: I found the firmware I used, it was the one originally from @Gixxerfast , you'll need to compile it: https://github.com/gixxerfast/Duet3Expansion/tree/cannedboard

@Th0mpy
@Gixxerfast

I need to look at the settings, so I get emailed when someone responds; sorry about that.
I might be interested. I would like to see if I soldered correctly. (it is my first SMD DIY project)
But I would like another one since it is going on an Idex printer if I want to go super extreme, lol.

Do you know if @gixxer is planning to make a more modern firmware? That latest is 3.4 from what I remember on Gixxer's GitHub and the new stable release for duet is 3.46

Th0mpy

@VoodooBane I don't know, I haven't seen them online for quite some time. It's pretty simple, however, to update and compile the firmware. To be honest it's been a hot minute since I touched it last.

I was looking around for someone else and either I sold them all or completely lost them in my shop

I am considering a new order of them, if I get enough interest it would push my decision up a notch.
