@JabawokJayUK Ive fixed the obvious H4 H0 issue in that btw but the site wont let me edit it as it gets flagged by Akismet as spam

@jay_s_uk yeah tried that. i'm a dumbass, i had the 2nd tool mapped to the first tool extruder in the config. hence why i was scratching my head

That solved it. thanks. I didnt know that the second pin statement was relative. Its not loosing connection, it was just bitterly upset with that config all fine now.

Hey smart fellows, I have a heater/fan config and am having some issues that I would like advice on if possible.

I have a bed heater, 2 extruder heaters, a water pump (fan), a chamber heater and a chamber circulation fan all connected across multiple outs on a Duet 3 Mini and a Toolboard LC1. While everything works in the config below, I would like to revise it and have had weird results when I try!

The above config is delivering the following functions:

• Turn on the Water Pump if either extruder > 40c (works)
• Enable and Run the bed (works)
• Enable and run a chamber Heater linked to the chamber thermister (works)
• Enable Radiator Cooling Fans and link to Water Temperature between 20-40C (works)

The basics of what I "would like" to achieve is that the chamber circulation fan (F4) is enabled when the bed (H0) gets over 50C rather than the chamber thermister. However if I change my config to reflect the H0 heater in the M106 command for the Chamber Fan, it just comes on and stays on at any temperature as if its conflicting with another command.

Also, for some reason, in this config, I am not getting the feedback from my Waterpump speed. but If I remove aspects of the config or switch from 12v to VIN on the Out3/4 connectors, it suddenly jumps into life, as if the sensor channel on the board is being shared with another out and the two signals cancel each other out?

Any thoughts based on what you see?

Many thanks

@jay_s_uk said in DUET 3 mini 5 wifi unstable:

what do you class as the latest firmware?

3.4.5 Stable.

@sebkritikel I'm sure thats what happened to me initially, which led me down the rabbit hole. Appreciated.

@Phaedrux I have previously tried all of those options. Dedicated 2.4ghz SSID, and multiple tails / multiple antennas (2-10 dBi) both directly connected or with extensions to locate the antenna in better air. Its not a physical issue.

Its either a bad board or a firmware issue, and the solution to both is to move to wired. I didn't want it to be connected over wifi initially, as I intended to use it in SBC mode, so it wasn't an issue, and I had this wifi version spare. Still, now I intend not to use the SBC so replacing it with a wired version is the logical option.

@dc42 it's printing at the minute, so I don't want to go poking around the wiring. I will take a good look at the wiring later, and if I find an obvious issue, I won't reply to this thread! The fact it is not expected behaviour at least points me in a good enough direction to continue debugging.

Thanks for the assist.

A further point of clarification:

OUT3 is connected to a 12v water pump, but only the PWM & Tach signals are connected. +12 is direct from an external PSU.

OUT4 is connected to the 24v FAN (all 4 wires).

Neither device shows a Tach signal when VIN is selected. Both show a tach signal when 12v is selected.

@dc42 yes. the fan is on OUT4. the jumper is set to VIN.

@JabawokJayUK specifically: 9GA0624P6G001

@T3P3Tony sure, I am using a pair of these: https://publish.sanyodenki.com/San_Ace_E/book/#target/page_no=60

Hello all, Is it expected behaviour to lose the tacho signal on a 4-wire fan if you switch from the onboard 12v to VIN? on OUT3/4 on the DUET 3 Mini 5? I am using 24v 4 wire fans for a circulation system and if I use the 12v, I get a tacho signal, but if I switch to VIN, I lose the tacho signal.

Many thanks

@sebkritikel I'm sure thats what happened to me initially, which led me down the rabbit hole. Appreciated.

I had a little play this morning and the original "positive" offset works, although I was 3mm out. After tweaking the offset I can get the tool heads to react as expected:

T0
G1 X254 Y250 Z1

T1
G1 X254 Y250 Z1

Should I have to replicate this offset in my cura config or is the duet offset going to handle this automatically? I'm thinking specifcally of these X/Y offset setting in the Nozzle settings tabs:

I have 2 fixed tools on a single axis, E0 and E1. Assuming that E0 is the HRP as per the documentation, my E1 is exactly +13.4mm away on the X Axis.

If I set the tool E1 to have an offset of X13.4 it ends up 13.4mm offset in the wrong direction, if I set it it -13.4, it ends up 13.4mm out in the correct direction. like it added 13.4 to 13.4 in the firmware?

Its almost as if the offset wants to be X0 but then I have no idea how it knows where E1 is?

Here in the image you can see the previous positive offset marks in the glue stick to the left and the same offset set as a negative in blue. Black is E0.

Firmware is 3.4.5
