@chrishamm on the bottom it says the first 10 pins are on gpiochip0. I switched it in DWC config but it just gave an error 22 this time, so I guess this isn't helping either.

@chrishamm said in SBC mode on non-pi's:

echo 480 > /sys/class/gpio/unexport

bash: echo: write error: Invalid argument

My understanding is this has been depreciated so it might not work properly.

@chrishamm I'm getting an operation failed error. Failed to open IO device. Error 19. Cannot put line into event mode. I applied the settings you gave me. Seems there's something still amiss here.

How do I determine the transferreadypin on a lepotato?

I considered attaching a flat magnet to a 3d printed shark fin and letting it cruise around the sand like that, adding felt to the bottom of the magnet to quiet it, but then the sand would need to be even deeper, etc. I think sand tables are beyond my skills. I still haven't planned out out to do designs yet. It's easier for a circle than a rectangle.

@achrn said in SBC mode on non-pi's:

any more probably needs to be moved to an off-topic discussion.

link me there and we'll chat about it sometime. I'd love to be able to finish this thing.

@achrn You're the guy behind Sisyphus? I built a large rectangular coreXY coffee table that was inspired by that, but I never finished. At the moment, I just solved the ball not grabbing the magnet strong enough (by getting a magnetic ball) but now have a very loud dragging through the sand problem. I ended up adding WLED on the edges for lighting effects and used it as a college project.

Sisyphus was so cool.

@Phaedrux why does it have to be so powerful? it's just hosting a web server and streaming data to the control board. I would rather not use it in face but the uploads on wifi are unstable, slow, and only work if the card has few or zero jobs on it.

edit: I have the pi4 set aside for tinkering with. The 2 and 3 are indeed shorting and the nanos are closer to the pi 2 in speed. The rock64 has a damaged power port and I don't want to hack up the gpio cable to feed it that way.

So I found the le potato on amazon is available and has not been price gouged like the pis. Looks like that and Armbian will be my route. Thanks

@Phaedrux I have a rock64, a pair of old pcduino4nanos, a pi 2 and 3 (but I suspect they have shorts somewhere) and a pi 4 I'd rather not use for this.

Does the SBC mode only work on raspberry pis? They are kind of hard to come by now and there are many pin-compatible (and pin-close-enough) SBCs out there.

@pkos no AV, just the built in firewall on macOS.
@Phaedrux 3.3.0. I Don't use chrome. I avoid Google products when I can.

EDIT: I forgot I have lockdown installed! Turning it off fixed this. But what is lockdown blocking that breaks DWC?

In both safari and Firefox, I cannot load the webUI completely. The farthest it gets is in safari, where I gets some UI elements and dark mode down after a while, but goes no further, showing a failed to connect network error in the lower right corner. When I try to access it off my iPhone mini, though, it pops up fast and error free. I cannot figure out what's wrong.

@phaedrux that’s exactly what I’m thinking. You’re right about just tying it to the heaters though. I’m not doing anything major with those steppers with the heat off. Good idea.

Is there a way I can activate a cooling fan only when the motor drivers are active, then disable the fan again when drivers are inactive?

I want to put my BL touch on IO_1. Can I use the in and out pins on that one connector at the same time or only one of them, meaning the in pun would be moved to IO_4?

I'm not entirely sure if I and O pins on this connector are sharing a pin on the MCU or not.

@jens55 I rolled back to the stock board and will just be using Klipper for it instead while I take a closer look at this board. I cant turn the parts fan on and off so I think there's a dead mosfet on here too. I measured with the stock board and it was 0.2 volts higher than the duet. I tuned the voltage up just a touch to hit 24 even even with the bed head on. shouldn't matter but meh.

My soldering skills are potato-class so I might not be able to repair this board.

@jay_s_uk It's a brand new printer.

@jens55 So measure in parallel with the bed rather than measuring with the meter connected where the bed would normally be?

EDIT: 23.4v. not great, but not bad either, right?

@dc42 I disconnected the bed in the chamber and measured there. 24V dead on. o_lampe, what s this about adjusting fans?

My duetwifi has been moved between multiple printers. I love it so much, every time I get a new machine, the first thing I swap in is my duet board. I have had to repair it a few times. The connectors for the bed and extruder heaters broke free (tiny gaps between solder and the pins) and had to be resoldered. It's been a great board.

It was just installed into my ender 6. While working on tuning, I noticed the bed heats MUCH slower than the stock board. It was slow then too, but it wasn't as severe as now. It shouldn't take 5 minutes to hit 70C, should it?

I also notice the fans spin much more slowly than if I directly connected them to the PSU. A little slower is expected, but this is quite a bit more than normal.

My theory is that along the way, something must have broken or worn down that I haven't seen yet. It's been several years, so maybe I should just retire this board. Ideas?

@phaedrux It's at 12v....because the LEDs are 12v, but the rest of the system is 24v! Of course!

I'll try fixing this tomorrow but I seem to remember there was some reason I had it wired up this way.

EDIT: I remember, I blew some of the mosfets on the duet over the years so the duet fan headers don't work right, hence I used the deus. I really should fix this things properly someday
