Help needed - Installing Duet 3D 6HC in replacement of a SKR 1.4
-
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?

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

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_ConnectivityThat 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.
-
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.

In that case please try this method of updating as you may be missing a few files.

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.

Hi @Phaedrux ,
Thanks, got the bed working properly now. just need to add the filament sensor details in the config.g and I should be able to try a first print!
-
Hello there,
I'm upgrading to my creality ender 5+ with the duet 3 6HC.
@aldiallo
Are you done and ok with the configuration ?
If yes, can you share with us your last config ?Thanks a lot.
-
Hello,
My setup still needs some tweaking to be 100% operational, I can print and the prints come out very nice, I'm really impressed, but they're still a few things that I need to iron out.
For example, when doing a mesh compensation, I have several point that are unreacheable so need to dig a bit on that as well as on a issue when homing the Y when running the home all command.
Are you using stock Ender 5+ or have you added any mods to it, reason I'm asking is that I tried inspiring myself from 5+ users setups but they were not neceserally stock as mine isn't but the difference in components has some impacts on the setup.
Here's my config.g file if that can help, please note that I'm using a microswiss direct drive so my E steps will need to be changed on your side unless you're using the same hotend.
Please note also that you'll need to modify in order to match your wiring.

@aldiallo Thank you for the sharing and the infos.
I'll take attention to the difference.At the moment, I'm using a stock ender 5+ and I want to fisrt setup the duet with this configuration before going on other mod.
I didn't find other user with stock ender5+ (only 5 and 3)
I also got a lot of issue understanding the mesh compensation en duet 2 with the homemade printer at the point that I switch back to an optical endstop.
I'll let you know.

Hi @aldiallo
I'm getting down the configuration.But at the moment, I'm stuck with 2 problem :
-
the BLTouch is in error directly when switching on the duet...
Last time I used the ender with the creality board, it was working fine...
Did you got that too ? -
Heated bed not heating up :
As read above, and said by @Phaedrux I took out the creality mossfet .
Wired the 24V power in the VIN and connect my 24V bed directly on the OUT0
Should I double the wire to OUT0_input from the same power station ?
-
-
@FLoRo Check the wiring for the BLTouch, post your config.
@FLoRo said in Help needed - Installing Duet 3D 6HC in replacement of a SKR 1.4:

I'm not sure what you mean by this. OUT0_input should either have a direct connection back to the PSU intended to supply the bed heater, or a short jumper connection to the main VIN input right beside it.
