@aldiallo some photos of your board cabling and the config.g will help us troubleshoot (-:

Sure thing, here you go fot the config.g file, I'll upload some pics shortly:

this is missing the offset of the probe

did you swap temp1 and 0? is this on purpose?
B4138 is the default and must be adjusted for your thermistors used.

Here are the pictures:

jay_s_uk

You need to provide power in to the OUT 0 power in to be able to use OUT 0

Hi @Veti

Concerning the BLTouch, that's strange as I set it to the default 2,5 mm.

Concerning temp0 and temp1, I have the bed thermistor on temp1 and the hot-end on temp0; should it be the other way around?

I'm using the stock ender 5 plus thermistors, I believe that in the case of the hot-end it should be a 100k one from I've found in the web, but no clue on what value to use for the bed, should I be using the same as the hot-end?

thanks

aldiallo

Hi @jay_s_uk,

Oh, ok, I thought that the bed will be taking automatically power from the power in and feed OUT 0.

thanks

you position of the bltouch is the same as the nozzle, this is physical impossible. you need to change the x and y value

ok just checking that is was done on purpose

try the values from the ender 3
https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38
Set the values for both Thermistor values as: R25 – 98801, B – 4185

Sorry, I got you wrong, the 2,5 mm I was reffering was the trigger height which I left at default, I'll go ahead an make the changes to the X and Y offset, thanks

Will check that, thanks, will also refer back to the marlin config, which I should have done in the first place

Hi everyone,

Making some progress here, manage to get a few things working but others are not working properly or not working at all.

X and Y homing ok but on the Z axis I only have one motor working, I did used the M584 command as advised but is not seem to be taking it into account, so when I try to home Z, I must do the 2nd motor manually; this is what I sent as command: M584 X0 Y1 Z2:3 E4

The Bed is not heating, I guess the wiring is not correct; not sure how it should be done on this board, I previously had cable the 2 cables going to the bed to the out 0 but that wasn't work so moved the cable to the out 0 Power In, but I still have the issue.

I'm also getting this error and not sure what's causing it: Warning: 12V under-voltage event (9.4V), might be related to the bed not heating up issue.

Have 3 fans, one for the board on out 4 working fine but the other 2 on Out 7 and 8 for the part cooling fan and the Hot end fan, both are turning, but this I assume is due to the temperature not being reached.

Also, where should the filament runout sensor should be plugged and how must one go to declare it as such? I'm guessing that the IO_x ports are my best bet.

Here's my config.g file, please let me know what errors do you see that I'm overlooking, thanks

Try Z0.2:0.3 to match the syntax of the other drivers.

Also please send M98 P"config.g" to see if you have any other configuration error messages.

Also provide the results of M122.

Ok, so the issue with the 2nd Z motor is sorted, thanks Phaedrux!

now need to sort out the Bed heating issue as well as the fans, the undervoltage warning and figure out how the filament runout sensor should be wired.

I'm really impressed on how smooth and silently the motors are moving compared to my previous skr board; once I managed to work my head around all of this, I might order another board for my Sidewinder X1

RepRapFirmware for Duet 3 MB6HC version 3.01-RC9 running on Duet 3 MB6HC v1.01 or later

First step will be to update your firmware to 3.1.1

Upload this zip file as is (don't extract it) to the /system folder via DWC.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

then we need some more info on your hardware.
What kind of endstops are they? How are they wired?
What kind of filament sensor is it? It would be wired to an io pin as well.

Heaters should be PID auto tuned to give the firmware a model of their performance. That will solve the not heating fast enough error.

When does the under voltage event occur?

aldiallo

Hi Phaedrux,

Ok, will do the update now, concerning the hardware, is just the stock hardware for an Ender 5 plus, yes the endstops are wired, same thing for the filament sensor is the stock on and yes also wired, I have it connected to the IO_2.

Shouldn't I be doing the PID auto tune once both (hot-end and bed) are heating properly?

My issue seems to be wire related, you can see on the pic below that the 2 thin cables going out of the mofset where plugged on my previous board and provided electricity to the bead to heat up, now on the new board, it seems that it should not be plugged that way, please note that currently the cables are plug into OUT 0

bed wiring

concerning the under voltage, I'll make some other tests and revert back

Phaedrux

I would abandon the creality mosfet and use the Duet 3 to power the bed directly as it's rated to 15a. Keep in mind that the bed heater ports on the Duet (out0) are powered from the adjacent out0_in ports which should get power directly from the PSU or be bridged from the VIN.

6-way barrier strip: two pins for main VIN and GND; two pins for the VIN and GND supply for the OUT_0 terminals; and positive and negative OUT_0 terminals. OUT_0 is intended to drive a bed heater. The ground side of OUT_0 is switched by the mosfet and the positive side is protected by a 15A fuse. If using the OUT0 terminal to drive a SSR, take note that their polarity is opposite to the polarity of the VIN terminals.
https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_Connectivity

That may be why your bed isn't heating at all. From you photo it looks like you don't have power going to out0_in.

If the filament sensor is just a simple switch for filament presence detection you can check out the M591 command.

https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_filament-out_sensors

https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing

Which ever io port you connect the filament sensor to would be used in the C parameter of M591.

aldiallo

Ok so you recommend to remove the mofset completely, correct?

Ok I'll work on that tomorrow, any way I'm swapping the power unit so will do that then

Yes the filament sensor, is just simple switch for filament presence, I might change that in the future with something a little more feature rich.

Tried updating the firmware but no luck, it starts loading the files but never seem to stop, it gets to file 6/18 and then it just keeps uploading without saying what or stopping.

Correct. I'd trust the Duet 3 more than anything Creality has ever produced and if you're using the stock ender 5 bed the Duet 3 is more than up to the task.

Got the board up to date on 3.1.1 now, thanks.

went on a removed the mofset and cable the bed wires but still not luck as I'm getting the error below:

Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec

OUT0 Power in is is now directly connected to the psu and the bed is wired directly to OUT 0

PID tune the heaters and save the results.
