@phaedrux Hello again! I ended up doing a complete fresh reinstall from the configurator then made sure I was using the latest stable release.

Good news is I am now connected to DWC 3.3.0, bad news is I have a new issue here.

M122 printout is being flagged as spam by Akismet. I will try and snippet the relevant.

Even better solution: I hooked up the power wires for my laser to the bed heater output and made that a GPIO that I then turn on and off via gCode.

@jay_s_uk Thanks! Now they're actually in sync that should be much easier through DWC. Back on track

@Phaedrux will do! But… I can say it does remain because my E-stop isn’t hooked up to the duet but to the mains. In an emergency I want everything to stop. Full power cycle is on my list of standard troubleshooting approaches.

I haven’t had any issues since my last post and the only thing that’s changed is that I’ve commented out the line declaring DWC needs a password.

@gloomyandy
Please excuse some of the comments in the config.g... I tweaked and tested a lot and reused code from another machine of mine so ought to go through and clean up the comments a bit...

Also, since posting and getting a backup copy of the SD (just in case) the machine's been running seemingly fine and is an hour or so into a laser job. In all honesty the unpredictable nature of the issue is more concerning as those usually have a more hidden solution.

@gloomyandy Apologies, yes, M552. Been slightly on autopilot.

Morning!
Or, afternoon now, losing track of time with this issue!
So, during calibration and tweaking a few days back I had to hit my emergency stop button and then was having serious issues trying to connect.
I somehow got it stable again (serial in, M552 S0 M552 S1 M997 S1 etc) and enabled logging.

I had reason to kit my emergency stop again today and have the same issues. I've spent a couple of hours trying to connect so now turning to the forums.
When booting up DWC looks like its loading then will stall on the "connecting" bar that hovers over the GUI. The green "connection established" bar in the background shows up, times out and vanishes but the blue "connecting" bar will just sit there. This loops over and over.
I also see the orange "HTTP Timeout" warning and, more interestingly, a red "HTTP: Failed to get file list" error. I remember last time getting "ISP busy" errors but haven't had any so far this time round.
Occasionally I get a clean startup, usually after connecting via serial with main power off and Initiating M115 S0 and M115 S1.

M122 reports back good connection, hovering around -32 to -34.

Look at how many "login succeeded" messages there are for my computer's local IP. Something's up and I don't know what or what more to try, at this point I can't really use my machine.
If anyone has any advice or pointers I'd be very grateful, thanks!

@o_lampe it wasn’t, as it happens. I redid the firmware from scratch using the RRF configuration tool which gave a slightly different setup to the one I was working on when I asked the spindle question.
Ironically having fixed the issues I’m back to essentially my original spindle config.
What I’ve ended up doing to solve that original issue is break out heater3 (and 4 for the laser) and use those to PWM drive an external MOS chip that level shifts the PWM to a breakout from the fan 5V… which is then the right level and “side” of the spindle controller to control it properly!

It seemed to work when I tried it at 9:00 last night but that’s my cutoff time for trusting my brain not to do something stupid so I’ll be doing more tests and checks this afternoon.

@dc42 Sorry, got there myself with some playing around when it got more verbose and pointed me towards config.g and now sorting my config properly. That's irrelevant to this topic so I'll mark it as solved ◡̈

@dc42 Good afternoon and thanks!
I deleted out the current IAP and uploaded the one linked (thanks). M997 took longer to execute this time and upon running M115 I am happy to report she's now on RRF 3.5.2!

EDIT: I am however getting the following error:

Error in macro line 47 while starting up: exactly one of EFHJPSR must be given

I can't seem to find reference to this anywhere.

@dc42 thanks for the suggestion! I just tried that with a fresh download of Duet2CombinedFirmware.bin version 3.5.2 and uploaded to 0:/firmware.
It uploads and asks if I want to install the file, which I agree to. After reconnecting I queried with M115 and got this back:

M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.3 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-06-15 21:45:03

I then tried M997 and M997 S0 both times returning the same thing. I've deleted out the Duet2and3firmware directory and retried.

Interestingly it hasn't complained about the file not being valid, but hasn't actually updated by the look of things.

Morning!
I've been struggling to update my Duet 2 WiFi from RRF 3.3 to 3.5.
I did a fresh SD using the RRF Config website but despite having selected 3.5 it defaulted to 3.1.1.
So I managed to manually get it up to 3.3 with the aim of getting to 3.5 in the next step.

DWC V3.5.1

No firmware files in 0:/sys
0:/firmware contains the following:

• Duet2and3firmware (directory, V3.5.2)
• __MACOSX
• DuetWiFiServer.bin
• Duet2CombinedIAP.bin
• Duet2CombinedFirmware.bin
• Duet2_sdiap32_WiFiEth.bin

When I run M997 S0 I get this error:

M997: Firmware binary "0:/firmware/Duet2CombinedFirmware.bin" is not valid for this electronics

Any ideas on what I can do to fix this? Thanks for all the help!

@gloomyandy morning, thanks for checking that with me. I read all the docs to do with laser control thoroughly when I was using this board for my laser cutter. At the time I’d ordered the expansion board to do it properly but the delivery guy marked it as “left in outhouse” (we don’t have an outhouse) and I never saw it again. In the end I connected it to fan0 as a 5V capable PWM and I’ve had almost perfect control over the laser prior to this setup.
The one issue I got was it powering up for a second at initialisation, I had figured that to solve that I could set bedheater as a GPIO and essentially use it as my power control for the laser. This in testing has worked fine but one of my tests today will be to decouple that and run the laser directly from the PSU like it was previously just to sanity check that setup that I know ought to work.

For the spindle I could try feeding it a 5Vref from the fan0 connector to the speed controller, good shout. Laser I don’t have that option unfortunately.
