So I made the 8 way cable up, using pins 19 - 26 in a one for one configuration.
Did not work.

Plugged in the original supplied cable, it worked.
Thought it could be my new cable, used patch cables instead, still not working.

Read more, Pin17, patched that in. Now it works!
As per the above post, Duet3's need a 3.3v feed from/to pin 17

So recap, pins required are the following
17, 19, 20, 21, 22, 23, 24, 25 and using two 5x2 DuPont blocks in stead of the 4x2's

I am using using a piece of Cat5e Ethernet cable.

Hope this can help others.

Paul.

Sure there is a way, which will require someone more knowledgable than me to assist!

Before my last upgrades, these configs are for Ender3 Pro which has a Bullseye duct and its BL Touch Mount, I am also running a Maestro board in my printer and using a PanelDue touch screen. All original hardware.

Update....
I took the time last night to remove the Mini 5 from my printer so I can send to Tony. Thanks @T3P3Tony
Whilst at it I checked the fan cabling and found a melt spot on one of the cables. There was also a mark on the brass where i realize now it had shorted, me being inquisitive wiped it to see what it was!

As per the LDO part number and spec sheet which is above in this thread, 800ma is way too much for this little motor, even though they say it is rated for 1amp
The motor was that hot it burnt my fingers when checking the issue, in turn had heated the brass standoffs which then melted the sheath of the fan cable that was resting on the brass. (The whole lot is in a chamber)
Also you can see the heat shrink has been shrunk by the extreme heat. I put them on loose!

All the printers I have built and used the 80% rule, i have never had this.

However lesson learnt, replace chinese cable with silicone or use a protective braid.

For those who think I did not RTFM, I did and always do! Hence how I got into this mess!

I have a room temp sensor and a secondary bed sensor purely for feedback.

In RRF3 I use

M308 S7 P"exp.thermistor7" Y"thermistor" A"RoomTemp" T100000 B3950 R4700

Then I have to go to the 'Extra' page to view.

@steve-lynch Here are all my files for my RailCore, running a Duet3 Mini and 1LC toolboard.
sinned helped me as I was having an issue also.

Hope they help you.

I am in the uk and bought a pack each of 5 of the 2 and 3 pins with tails from here

Here is my config for BLTouch - Duet2 with Duex5

config.g

; Z probe and compensation definition
M558 P9 C"^zprobe.in" H5 R1 F120 T6000 A5 S0.02  ;BLTouch connected to Z probe IN pin
M950 S0 C"duex.pwm1"				             ;BLTouch Servo (S0) on duet pwm1
G31 X2 Y42 Z1.438 P25                            ; Customize your offsets appropriately - do a paper test, and put the probed value in the Z value here
M557 X30:280 Y30:280 S20

Your M950 and M558 are the wrong way round, I made the same mistake!
I am sure the guide is wrong!

Nothing important.....
Hope this helps @dc42

Thanks Tony.
Issue was, I forgot to put my silicone sock back on to the heater block Doh!

First big print and getting used to the new printer and using Prusa Slicer instead of Cura

The duct and fan for part cooling is tooo good!
Never had these problems on my Ender3 !!! LOL

Thank you and sorry.

P.

homeall.g deployprobe.g bed4point.g retractprobe.g homez(1).g

These are all my WORKING homing files.
And my config.g
config.g

After running the Z homing, instead of running G32, type the commands from your homez.g or mine.
G32 iirc runs bed.g, i do not have a bed.g
rename bed.g to oldbed.g
When I run g32, it says bed.g not found, so remove, move or rename it.

homez does everything, i think.

You are nearly there.

So it homes Z OK.
Just the 4 point mesh is the issue?

when you MANUALLY connect the probe to its dock, does Z-Probe in the dashboard change from a Red 1000 to 0?

@sgk why are you using 2 io's?
Please post your config.g, not just bits of it.
Also a picture like below, WITHOUT the Euclid connected.

P.

Firstly I would make sure the probe works correctly.

Get the EndStops Monitor plugin from Here

Click the 'Plugins' button on left toolbar

Then click

Select the file you just downloaded, and install it.

When it is installed, you need to enable it by clicking the green 'Start' button

Press 'F5' on your keyboard to refresh the printers webpage.
go here

Click the 'Endstops' tab and it will display the status of your endstops

With the Euclid NOT connected it should say 'Yes' under triggered

With the Euclid connected and the switch NOT activated your screen should look like this.

Also note the 'Z-Probe' field in the 'Status' box at the top of the screen

When the Euclid is connected and the switch is NOT depressed it should read 0

When Euclid not connected it should read 1000 and be high lighted in RED

If this is not the case, add a '^' to this line, like mine.

M558 K0 P8 C"^io0.in" H8 F300 60 T9000 A3 S0.01

Let us know how you get on.

Regards,
Paul.

@jay_s_uk @R4ffers
Thank you.

@Gixxerfast is this available to download from somewhere? I have a spare toolboard and would like to use this on my 0.1, until I build my RC Mini

Regards,
Paul

I use SuperSlicer. I had a speed issue, not running as fast as you are trying to reach!
It was down to my 'Max Volumetric speed' which is set up in Filament settings in SS.
Could be part of the issue

@bilsch This is from Fulgs config....
M671 X-65:-65:365:365 Y0:395:395:0 S20 ; Define Z belts locations (Front_Left, Back_Left, Back_Right, Front_Right)

Which can be found here.
https://github.com/Fulg/VoronUsers/blob/add-rrf3-config/firmware_configurations/reprapfirmware-duet3-mini5%2B/fulg/sys/config.g

Use it as a reference, as it was created in 2021

@bilsch what are you using to level the bed? Inductive, BLT or Euclid.
Also what size 2.4?
