Homing X, Y, Z disconnects the Duet 3 3.3RC1 SBC

[CrazyCreator]

I don't know if someone has had the problem before or if i'm the first.

When I try to homing any axis in DWC my Raspi apparently loses the connection to the Duet.

The error message: Warning: Lost connection to Duet (Board is not available (no header))

Before i can move all axes manually (send: M564 S0 H0), but as soon as i press the home x or y or z button it loses the connection ... Although I can still click further in the dwc navigation ... after disconnet, only no motors can be controlled or driven and all sensors disappear (Power and MCU Temp).

What i try:

• On PanelDue Display i can homing without errors
• I have just replaced the Raspberry's SD card again and reinstalled it ... But the error remains.
• If I put the same config directly into the duet 3 then the home buttons in the DWC work normally, i cut the connection to the raspi for this.
• Change the Raspberry

My hardware: Duet 3 MB6HC + 3HC + Raspi 4
Raspi power seperatly or from Duet make no difference

Can you post your config.g and your homing files as well please?

[CrazyCreator]

@phaedrux Yes of course I can post them ...

homez.g
homey.g
homex.g
homeall.g
config.g

...and just for Info:

[Phaedrux]

I think you may be affected by these limitations in RRF3 as you have your Z motors on the expansion and a probe.

Endstop switches and Z probes connected to the main board cannot control motors on an expansion board. This is planned to be fixed in release 3.4.
If you use a Z probe then the Z motors must be connected to the main board. This is planned to be fixed in release 3.4.

Also, you have multiple extruders defined in M584, but don't have the values for each extruder defined in the other commands.

@phaedrux
But it does work ... All end stops react correctly.
From the PanelDue display I can use the Home X, Home y and Home Z as normal.
When I insert the SD card into the MB6HC, the homing from DWC also works too.
Only when I use the Raspberry does it not work.
Do you think that is really because the Z motors are on the 3HC and the EndStops are on the MB6HC?

Then I'll have to rebuild it this afternoon.

I already used a different config for testing ... the one from the jubilee printer.
There were X, Y and 3xZ connected to the 6HC, but I had the same problem ...

But I'll try again anyway

[dc42]

@crazycreator, I suspect that you have hit a known issue with a stack size in 3.3RC1. Please upgrade RRF to the 3.3RC1+1 binary at https://www.dropbox.com/sh/dlb58vkmu1u4fkx/AAAelkXSfRKVwI6_yqRnhGHPa?dl=0.

[CrazyCreator]

@dc42
I upload the files per DWC on my Webbrowser
Duet3Firmware_MB6HC.bin
Duet3_SBCiap32_MB6HC.bin
Duet3_SDiap32_MB6HC.bin

Now the MB6HC is on Version 3.3RC1+1 but the 3HC on 3.3RC1

I can now X and Y home ... but after the click it will take 10-15 seconds for the printer to start moving.
when i press home z nothing happens. no error message and no movement only the "busy" status.

Without testing Homing ....
X and Y continue to work and moving
The Z axis can no longer be moved

[dc42]

@crazycreator said in Homing X, Y, Z disconnects the Duet 3 3.3RC1 SBC:

Now the MB6HC is on Version 3.3RC1+1 but the 3HC on 3.3RC1

That is correct.

That is not right. Please do the following:

1. Send M122 P1004. The main board will reset.

2. When it connects again, home X and Y again. When that has completed, run M122 and post the report here.

We expect to release 3.3RC2 later today, so you may wish to wait and test with that version.

[CrazyCreator]

@dc42
i went down to 3.2.2 and everything works fine.

If you say there is a new release today then I'll wait for it and report here.

P.S. After installing your RC1 + 1, I restarted the entire system ... So it was de-energized.
I think this does the same thing as M122 P1004, right?

[ctilley79]

@crazycreator I have this exact same issue. I have to restart the duetcontrolserver process on the pi to bring it back.

@ctilley79 strangely enough. Home all works, and it calls the x y z macros with M98 and works fine.

[CrazyCreator]

@ctilley79 I will now wait for the release today, as recommended by @dc42 .
Then we see if it works and if not then @dc42 can continue to do magic

[Phaedrux]

3.3 RC2 is now available: https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3RC2

[ctilley79]

@phaedrux Has it hit the package servers yet? I'm not seeing it. For clarification, if you're using SBC, you cannot update the board firmware via uploading in DWC correct? DuetSoftwareFramework has to be updated before every release?

[ctilley79]

@phaedrux Ok. It hit. RC2 Solved this issue for me. How about you @CrazyCreator?

[CrazyCreator]

It works
