@gloomyandy You are quite correct. I am measuring the voltage using a digital voltmeter. (I do not have access to an Oscilloscope) I had a suspicion that this may not show the variation in voltage because of the PWM. But I did not know enough about the subject to be sure. I will install the PWM to analog converter and measure the output from that.
Thanks for your comments. I think they were helpful.

@jay_s_uk I already have the PWM to analog converter, I’m trying to confirm that when I issue M3 Sxxxx the output actually changes before I connect the converter.

My testing so far has been inconclusive in that changing the value of S does not appear to affect the measured output - it is fully on all the time.

Thoughts, comments?

Hi, trying to set up a duet 2 wifi running RR3.3 to control a spindle on an Ooznest CNC.

If I run these commands:
M950 R1 C"e0heat" L1000
M563 P1 S"Spindle" R1
M3 P1 S1000

When I measure e0heat I get about 24V (dc)

I don't seem to be able to use "M3 P1 Sxxxx" to change the measured voltage on e0heat - it is either 24V or 0v.

I'm sure I'm missing something - can anyone give me hint as to what?

TIA
Tony

@phaedrux One thing I had noticed was that I seemed to get different results executing the commands, - sometimes they appeared to work OK, other times they came back with a negative result,

I must admit, from what I had seen on the forums, I had begun to suspect I have a hardware problem.

I got the Duet about 3 weeks ago as part of an Ooznest Workbee CNC kit - I'll engage with them to get it replaced.

Many thanks for all your assistance - very much appreciated by someone who is trying to get their head around what is, to them a completely new area!

OK downloaded and copied the bin files onto the SD Card. Results attached:

YAT Log.txt

Not sure if the wifi actually updated as it just shows 1.02 or later?

@phaedrux
addnetwork.g:

M552 S0
M587 S"xxxxxxxxx" P"xxxxxxxxxxx"
M552 S1

No special characters in the original network, Exclamation mark (!) used in both SSID and password for the second network...

Both networks running at 2.4GHz

@phaedrux
OK, ran the commands - this attached file shows the result...
YAT Log.txt
I did try to put the contents of the file in the body but it got flagged as spam?

Does this information provide any hints as to what I'm not doing/doing wrong?

I have also tried connecting to another network using a completely different router/SSID/password

Thanks,
Tony

@phaedrux
Will send response when I can get to the machine - it is in a different location to which I do not have keys, sigh....

As a matter of interest, are you happy to say which time zone you are in?

Thanks,
Tony

@phaedrux
OK, so I tried using quotes around the lower case characters - you were quite correct - it made no difference whatsoever.

This is the content of the YAT log:
M552 S0
ok
WiFi reported error: no known networks found
WiFi module is idle
M587 S"xxxxxxxxxxxxxxx" P"xxxxxxxxxxx"
ok
M552 S1

m587
M587: Failed to retrieve network list
ok
Error retrieving WiFi status message: bad reply format version

Which, while the response to the initial M587 S"NetworkID" P"password" command (ok) would seem to suggest things are ok; the response to the subsequent M587 (Failed to retrieve network list) suggests otherwise..

I'm sure I'm missing something, just having trouble seeing what!

Really appreciate the suggestions so far..

Thanks,
Tony

@speaker2animals said in Update Duet 2 Firmware without a network:

And that is where the 'fun' began, how do you update the SD card without network access?

Your PC or laptop may well have a SD card socket already. If it doesn't, you can get USB adapters for SD cards on Amazon, eBay etc.

Another possibility is to update the main firmware directly to 3.3 using the Erase jumper and Bossa. The WiFi firmware you already have should work with RRF 3.3 and when you have wifi access working, you can upgrade the wifi firmware.

That said, it should be possible to get your board connected via WiFi using your existing firmware 2.03. What is the problem you are having?

Hi, thanks for the quick response.

When I issue the M587 S"networkID" P"password" command I cannot connect to the network (can't remember the exact fail message and I'm not near the machine at the moment).

Since I posted I have seen some information that suggests there may be a problem if either the NetworkID or password have lower case characters? - this is certainly true of one of these elements for the WiFi I am trying to connect to.

I will try again wrapping the lower case chars with single quotes and see if that fixes it.

Again, thanks,
Tony

Hi all,

Please be gentle, while I'm ok with computers generally I'm now doing stuff outside my comfort zone.

I'm trying to get a Duet 2 WiFi connected to a network and so far am failing miserably.

I have established (via YAT) that the card is running:
FIRMWARE_VERSION: 2.03 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2019-06-13b2

Given the current Firmware is v3.x I thought I should probably update.

And that is where the 'fun' began, how do you update the SD card without network access?

There might be an obvious answer but if there is I have yet to find it.

Any suggestions?

Thanks,
Tony
