As alternatives, and for which I'll use to make an adapter cable, I found these:

https://www.aliexpress.com/item/1005004265820177.html

They are described as 63080 with 6.3mm pitch. This seems, maybe to be something like a Molex Minifit. Maybe. Who knows with Ali Express. I'll have a close look at it when it arrives. I suspect it will be OK for voltage (230V here) and current (surely at most 2A for the TLM heater).

I would have ordered something nice from Digikey, but in the past I have spent a lot of time and almost lost my sanity trying to find housings, both male and female, and terminals to suit the wire gauge, all which fit together properly and for which I have a crimp tool. The Ali Express store RiccoDi seem to have lots of "sets" including male, female, and terminals which really helps with the headache.

This is the last piece of the puzzle for the printer conversion to 1.5m rails. I really hope it works and produces some at least half way decent prints.

@martinv

Ahh rats, I think I found it on Digikey. 6.2mm pitch apparently. Unfortunately it seems to be obsolete.

Molex part 351-43-0201

@droftarts

I measured the pitch again today and get 6.1mm, so maybe it's actually a 6mm pitch. A bit unusual. Notice also the half rounded housing keying. After much searching I've found that the rounded keying is unusual; most keyed connectors seem to use 45 degree angles.

Here's another photo; having real trouble taking a nice shot alas. I'll have a look on Digikey for 6mm pitch housings...

Another thing I could do is instead of making a complete new cable, or splicing the old one with some nasty solder joint would be to use the cable I have to make a short adapter to a new (and importantly, obtainable) connector. Kind of like...

heat bed--->X X<---->known male/known female<------- ... 2m to power supply end.

Hi everyone,

My Google-Fu is failing me. Does anyone have an idea of what connector this is in the photo? My measurement of the pitch is 5.9mm (difficult to measure exactly as it's only 2-way).

For the whole story, I have a Tevo Little Monster delta where I have lengthened the rails. So now I have to lengthen all the cables. For the (mains powered) bed I'd rather build a complete new power cable rather than splice the old one. I could change to a different connector and be done with it, but Ideally I'll keep the original as I have a number of these printers and I'd like the possibility of easily swapping the beds.

@dc42 Thanks for the reply. I took a look at the link, but decided that's quite a departure from the Arduino and would be quite a lot of work to re-implement everything for a new development environment that's otherwise low on my radar. I'll hopefully set up a quick test in the coming days to have a look at the M118 command in more depth.

@droftarts Ahh! I think I might have found something useful - M118.

Eg. M118 P2 S"SET_TEMP 60"

This looks to send the string "SET_TEMP 60" to serial port 2 of the Duet, which I could pick up using the Arduino. Not sure yet how I could send info in the other direction though; like chamber presently at 53C. Or how I could get the Duet to wait until the temperature hits 60.

@droftarts Hmm, having had a look at those two projects as well as generally reading up on PanelDue it looks to me like the Duet sends status information (bed, hotend temperatures etc.) to the PanelDue and the PanelDue sends control information like axis movements to the Duet. So if you're wanting to get in the middle of that, it's all good. I'm not presently seeing how I might use this for a chamber heater interface however. The communication looks to be in the wrong direction, as in the Duet might tell the PanelDue the chamber temperature, not the other way round. Am I missing something?

What I kind of need is a way to see the G-code "as it goes by" to the printer so that I can control the chamber heater. Then somehow to report the chamber temperature back to the Duet. Hmm...

@droftarts the serial port sounds like a good idea to me. As you say there is the opportunity for feedback. Thanks for the idea!

Hi everyone. I have been experimenting with an Arduino controlled active chamber heater for a Prusa i3. This has been successful and so my next step is to build a chamber heater for my Duet 3 Mini 5+ delta machine. This got me thinking as to how I might control the chamber heater. Presently the Arduino
does everything, so brings the chamber up to temperature and then I start the printer printing. Then later when I see the print is done I can slowly cool the part down. All very manual.

For the Duet I'm thinking there is possibly a better way to do this. So I took a look in the Duet instructions and I see info on how to connect a simple chamber heater with thermistor and heating element. The thing is my chamber heater is more elaborate (Eg. multiple independently controlled fans) and so it would be better if the Duet could somehow tell the Arduino the desired temperature and the Arduino could report back the current temperature. Or something like that. I'm wondering if there is a meaningful way to do this and how. My brief searches suggest that canbus is used by a number of external boards, but if I went down this path would this require changes to the Duet firmware?

On one hand I have experience building and writing code for canbus devices for my day job. On the other hand, I don't want to embark on a massive mission.

@KenW interesting. Well it's been about a month now and I haven't had the controller WiFi issue at all since then, so it seems that avoiding allocating Wi-Fi channel 1 on the access point has indeed turned out to be a successful workaround. I mention this for anyone else having issues.

I decided that this was good enough and have ordered another Duet 3 Mini 5+ WiFi for my next Tevo Little Monster upgrade/conversion.

I haven't tried changing the firmware to the latest beta yet, but I have tried changing the configuration on the access point nearest the controller. I've changed it so that while it still assigns the WiFi channel automatically, it now avoids channel 1. See https://docs.duet3d.com/en/User_manual/Troubleshooting/WiFi_troubleshooting

It has been going a couple of days now without getting irretrievably stuck. This is longer than it usually lasts, so I'm hopeful. The log still shows lost connections, but it seems to be recovering each time:

If this works then that's great, but it would also be lame that it crashes if trying to operate on Wifi channel 1 (for whatever reason).

@danzaywer OK the problem resurfaced and I tried M552 S0 then M552 S1 and that brought it back to life. So it looks like either M552 S-1 or M552 S0 followed by M552 S1 works for me at least.

I'm running WiFi firmware version 1.27. I hope to try the very latest some time today.

@danzaywer The M552 S-1 is what I'm using. I saw this mentioned elsewhere in the forums when people had WiFi problems. Looking in the reference [https://docs.duet3d.com/User_manual/Reference/Gcodes#m552-set-ip-address-enabledisable-network-interface](link url) I see:

Snnn 0 = disable networking, 1 = enable networking as a client, 2 = enable networking as an access point , -1 = disable WiFi module

So there is a difference between disabling the networking and disabling the WiFi module, but the specific differences are not clear to me. If M552 S0 is working for you... Maybe I'll try it next time my controller gets stuck.

Looks like the new microSD card didn't help - the controller has done the same thing again:

WiFi module is idle
Error: WiFi module reported: network scan failed
WiFi module is idle
Error: failed to retrieve WiFi status message: SPI timeout
WiFi module is idle
Error: failed to change WiFi mode: SPI timeout
m122
...
= WiFi =
Interface state: disabled
Module is disabled
Failed messages: pending 0, notready 0, noresp 4
Socket states: 0 0 0 0 0 0 0 0
ok

Looks like I'll be trying the very latest firmware next...

@droftarts interesting. I took a look at all that and have decided to try another microSD card first. Let's see how that goes.

@danzaywer It's curious that both you and I posted messages at almost the same time. I'm also seeing the message "Error: failed to retrieve WiFi status message: SPI timeout" appearing in the serial output from the controller (I'm connecting via USB; I don't have a display), with the WiFi interface state turning to "disabled" after that and so no response to pings etc. For me power cycling fixes it, as does sending:

m552 s-1
m552 s1

I wonder if there is a firmware bug where the recovery from an SPI timeout is not being handled properly. I think first I'll look at trying the latest firmware, and if it's still doing it I guess have a look at the code if that's available. I'm new to Duet so not sure if the code's available but I guess I'll find out.

One thing I'm wondering, how many WiFi access points do you have on the same SSID? Is it just one, or do you have multiple?

My post FWIW [https://forum.duet3d.com/topic/34030/duet-3-mini-5-wifi-losing-network-connection-never-to-return](link url)

Hi everyone,

I have been experiencing an issue with the Duet controller in the printer I recently converted to use a Mini 5+ WiFi.

[https://forum.duet3d.com/topic/33758/duet-3-mini-5-tevo-little-monster-conversion](link url)

The issue concerns the Wi-Fi connection. After running for a day or even a few hours it will disappear from my network and I can no longer ping it. The green light on the Mini 5+ is not lit when this happens. To get it back I power cycle and all is well, until the next time.

I have tried pinging the controller from a PC in an attempt to 'keep it alive', and that works very well. I set up a ping and left that running for it must have been more than a week, and no problems. Then once I stop the ping, a few hours later I check and no more ping responses. So I could keep pinging but that's a bit lame. I also want to buy another Duet controller for another printer but I'm hesitant to buy the WiFi one again if it's going to behave like this, yet I want WiFi if at all possible rather than the Ethernet version.

So I hooked up a PC to monitor the USB interface, recording m122 output before and after the issue. Here is the log. Maybe someone can help identify a way to fix this problem.

FWIW I have other brand WiFi connected printers and am not seeing network issues with them.

The M596, M593 and M915 commands in there you can ignore - I was reading the G-code documentation and trying out commands. Then after that I printed a calibration cube, but it failed (filament break), so I restarted it. The cube printed to completion. Nothing happened after that until the issue where the first Error: line seems to be the WiFi module losing connection. Then it times out, then no known networks, then it gets stuck in a loop where the network scan fails. When I found it the next day I ran m122 and found indeed no WiFi. Then I tried M552 S-1 and M552 S1 to restart WiFi and that brought everything back to life.

Any help appreciated.

-Martin

This is exactly what I need; M556. Thank you!

@boldnuts

I see it looks like you made a cover (in yellow) for the mains wiring to the heater bed. Good idea!

@boldnuts

I calibrated the extruder as one of the first steps by measuring 100mm of filament extruding, measuring it, then tweaking the steps/mm value, now 398.62. It was slightly different to what I used with the original Tevo extruder which was 403 (which I just may have blindly copied from the Internet/elsewhere).

I know that individual filaments might require slight tweaking of this value, but I'm unsure how to tell the difference between slightly off extrusion multiplier and slightly off bed 'squish'. I'm thinking perhaps there is a test print that makes the over extrusion visible on a layer other than the first layer. Actually, if I just printed a block with two square towers separated by say 10mm maybe that would tell me. If the measured distance is less than 10mm then there is over extrusion. ... Or my scaling is off. Actually, now I remember, I did print a 50mm and 100mm test square and measured those and came to the conclusion that the extrusion is correct but I needed to scale the XY just slightly. I'm new to this so a bit to learn.

Here is a print I made yesterday. 0.8mm nozzle and 0.3mm layer height. Unfortunately it's different filament to before throwing an extra variable into the equation.
