@honeycris I think you be better off replacing the fuse with the same size that blew. Then move that 800W bed onto its own external mosfet and power line.

@fcwilt Yep Thanks for the help Put my settings inside the loop like you have. Works perfectly.

I got it... I love it when a plan comes together... Found the correct GPIO pin:

#68 located in device /dev/gpiochip1

thanks for putting up with my noise everyone

If you have one of these SBC's feel free to hit me up if you run into issues.

@paulhew I've been using it since it was turned on and it actually been pretty accurate and is spinning up my case fans reliably. So Far.

@fart_plume Right. That's correct. they only receive data during a print. should switch to :

Pulse-type filament monitor on pin io4.in, enabled, sensitivity 7.000mm/pulse, allowed movement 50% to 200%, check every 15.0mm, no calibration data

while printing. I cant remember what condition they collect calibration data under... if in doubt cut the filament.

@phaedrux said in Ask user to set bed temperature before bed mesh probing:

M291

How about writing a conditional macro placed the start gcode in your slicer to load a low|medium|high heightmap based on printing temp?...

@phaedrux Here is mine in io.4 of a mini5+

Black supplied wires reading "up" v3.3, signal, gnd.

On the sensor side I left it the way it comes from BTT. Which looking at it from the label side is a 4 pin plug only populated in 3 |V _ S G|
Where v is ~3.3-5v

in config.g
M591 D0 P7 C"io4.in" L7 R50:200 E15 S1

"M591 D0
Pulse-type filament monitor on pin io4.in, enabled, sensitivity 7.000mm/pulse, allowed movement 50% to 200%, check every 15.0mm, no data received"

I need to tweek the setting but its working fine.

@nurgelrot Nope. Don't use this one either It cools the board but causes it to drop below 4.6V from time to time... Who would think it so hard to find active cooling that works. Guess I'll wire a Noctua 40mm 5v right of my 5v PSU. Was hoping to not have to do that but since no one can make simple fan that doesn't block the header or screw up the voltage...

@keyz182 Man both myself and my browser's search function are blind.... okay well i set it the way i should have it through dumb luck. I can live with that.

Okay I removed the Q500 and that did the trick... I didn't think that would have any effect since they aren't PWM fans. And Q500 is listed for the default so you'd think that's what would be there even if it was not set but.. Fan is going like blazes now.

@phaedrux The RRF config tool makes them as 500 as well. So that may need to be updated

@phaedrux RepRapFirmware for Duet 3 Mini 5+ version 3.3 (2021-06-15 21:46:11) running on Duet 3 Mini5plus Ethernet (SBC mode)

Both the same
test print just finished on the one having the biggest issues:

7/23/2021, 2:10:29 PM	M950 F0
Fan 0 pin out5 frequency 250Hz
7/23/2021, 2:10:16 PM	M950 F1
Fan 1 pin (out6,laser,vfd) frequency 250Hz

@nurgelrot thats my second Mini5 not the one I was having issues on. (its printing right now and don't want to messit up) They are configured the same except the heatsink is 12v on this one. I'll check when it done printing but sshouldn'tbe different then this one.

@phaedrux said in Mini5 Weak Fan output:

M950 F0

7/23/2021, 1:57:34 PM	M950 F1
Fan 1 pin out3 frequency 250Hz
7/23/2021, 1:57:21 PM	M950 F0
Fan 0 pin out5 frequency 250Hz

I'm getting very poor fan performance from my part cooling and Heatsink fan on my Mini5 both are wired to 24v on out.5&6. I'd say I'm only getting about half their output when wired to the Mini5 vs direct wired direct to power on the same wires.... What do I need to do to correct this? And yes I'm positive I'm jumpered to VIN and not 12v I also tested with another controller board (running Klipper and they spool up nicely there.) Fighting a heat-creep issue cuz no fan is delivering enough ariflow.... So the fan on out6 is the most critical it hardly moves any air at all when on out6. Short of hard wiring it to the PSU I don't know what to do.

Just using the standard settings... And they aren't fantastic fans just WINSINN's but like I say they work a lot better connected to other things....

; Fans
M950 F0 C"out5" Q500                               ; create fan 0 on pin out5 and set its frequency
M106 P0 S0 H-1                                     ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"out6" Q500                               ; create fan 1 on pin out6 and set its frequency
M106 P1 S1 H1 T45                                  ; set fan 1 value. Thermostatic control is turned on

{edit} Just checked to cover my bases and in getting 24.1 V at the fan. So this makes no sense to me 24v is 24v why are they running slower when attached to the board. They are just dumb 2 wire fans.

@adammhaile Not really helping you current issue but have you considered other ways to do this rather than going through http? I'm basically backup all my printers "sd card" files with a simple rsync script. Since the SBC is gateway to a UNIX file-system why not use it?

I set up the ssh key from my fileserver to the printers and run a job through cron. My stuff all dumps onto a ZFS volume on my fileserver so I even get version control since snapshots are turned on for that filesystem.

I'm sure there are a ton of utilities you could use to do the same thing with Windows (powershell could do 90% of it alone I think). And MacOS is of course just wrapped up pretty UNIX tools... so no issues there.

@pcr Are these up for order on your tindie store page? Or basically how do I get my hands on 1 or 2?

@o_lampe No I have it working now with both the Hardkernel Ubuntu release and the Armbian release for the C4. No extra compiling required. Just followed the guide on setting up an SBC for Duet and improvising as needed. Getting the buffersize for SPI is a little tricky as it wont pick it up from modprobe. you have to pass it as a boot time param in the bootargs of the kernel (spidev.bufsiz=8192)

I'm really liking this board so far. Almost the same form factor as the pi3 just the HDMI port is moved and the power connector is different. Its 12v instead of 5 runs 15c cooler than the pi4 but still has the standard 5v outputs. Also has separate input for the tty console (in addition to UARTs on the 40pin) has option to hardwire to a PSU rather than the bulky barrel connector.

No WiFi/BT though, but given my experiences with the WiFi in the Pi that might actually be a benefit... 4 USB3 ports so a wifi dongle is no big deal and works better than a built in one anyway. Has the option to run of an eMMC chip or an SD card so "disk" IO isn't an issue.

Now I just have to run it for awhile and see if RRF play's nice with it.
