Fly-RRF-36 RP2040 Based CAN-FD Toolboard

@breed it is
-
@KenW I really wouldn't mix firmwares like that.
-
@jay_s_uk - Great news, and thanks for your efforts!
I just purchased Set 2 with the 31865 for the pt100 temp sensor and am looking forward to getting it set up on a Duet 6HC which has an additional expansion board 3HC.
Can you please give some instructions on the correct connection to the main boards and firmware to use in this setup please?
Also, is there a provision on the tool board to connect the filament run-out sensor used on the orbiter V2?
Thanks in advance. Cheers Ken

@KCMARINE all the info is here https://teamgloomy.github.io/fly_rrf_36_general.html

Have (4) paired with a Duet 3 6hc running on a toolchanger. I’m a little worried about heat with the board being covered but a o far no real issues and on board temps stay under 60C. My cover is as follows…
-
@KenW I'll gladly post what I have tomorrow in step format as you'll likely have to mod at least part of it to suit your needs.
-
@KenW back-cover.stp
I can upload the other part but it's pretty specific to my extruder. Let me know.
-
As an aside, I pulled the cover off after a 2 1/2 hour print last night and did the finger test for temps and nothing was above luke warm. I know it's not very scientific but it helped with some of my heat concerns.

I just plopped mine on top of the Y carriage of my Railcore lol
Facing a couple issues with the RRF setup;
Somehow it's not triggering my Y endstop;
- I have the microswitch NC pins wired to io1.in and GND (pins 2 and 4 of the 5P connector)
- endstop define in config.g
M574 Y1 S1 P"124.io1.in" - I've tested the switch for continuity at the plug and it behaves as expected (NC, breaks when pressed)
And still the endstop doesn't seem to trigger on RRF
Any tips?

edit: will fix my spelling on the wiki...
further edit:
here's the diode jumper
-
@jay_s_uk dang thank you for the quick response!
funny, I did have it installed, but because I read too quick and thought it was about the Z probe
well that doesn't help then
I've just tried without it as well and it doesn't do it either.I had initially connected the other side high to 5V by mistake; surely that didn't fry the gpio right?
-
@fractalengineer that shouldn't have done I don't think.
I don't currently have a board setup so I'll see if I can get one going a little later and plug a switch in. -
@jay_s_uk much appreciated; I've just swapped it over to io2 instead and it appears to be working; I wanted to use it for a thermistor or a filament sensor, I'll see if that works on io1
-
@fractalengineer maybe enable th pull-up ?
-
@oliof good shout. @fractalengineer try that
-
@jay_s_uk It's working now on io2 without pullup; I'll leave it there for the time while I move on with the rest of the setup.
thermistor doesn't work on io1; it can't do digital readI have another issue now while trying to drive my extruder (a LDO Orbiter with a modest LDO36STH20-1004AHG, driven at 0.85A)
I'm getting a series of over temp warnings, as the driver seem to get in a drive/reset loop for the duration of the move.
Measuring the board with my IR cam reveals 60 to 70c tops package temp on the TMC.
Any tips?
-
@fractalengineer weird; somehow increasing the current to 1A resolved it?
Railcore II ZL
-
you must use TEMP0 for thermistor. IO will lack the 4k7 resistor.
-
@fractalengineer 1A is a lot for this stepper, I run it at 650mA.
-
@oliof stepper is rated 1A, I normally run it at .85 but since less current didn't improve the issue, I tried more.
Extruder is recommended to run at 1.2A in the instructions (runs hotter but more torque)
TMC2209 Driver is rated 2A.
Speaking of, I did manage to get one print of it at 1A,
But on the 2nd one I got this message
I checked the driver and ye I got a dead short between B phase and GND...
Will pull the board out and investigate further
