@chrishamm so far so good. It looks like all the reset issues have gone away.

undefined

@chrishamm A quick update. On an intuitive guess, I performed a "rpi-update" to update the Pi5 firmware. This seems to be working so far, as I have not had any issues at the moment, and am running a print. I will report back if this proves to be successful.

State: 5, disconnects: 9, timeouts: 9 total, 9 by SBC, IAP RAM available 0x24cfc

Those resets were caused by the SBC. What kind of microSD card do you have? Is it possible that you enabled debug logging at some point in /opt/dsf/conf/config.json? And do you have enough free space on the card, does it have enough voltage to ensure that the CPU isn't throttled? And can you confirm that the Pi has no excessive load spikes?

I have this card:
SanDisk 128GB Ultra microSDXC UHS-I Memory Card with Adapter - Up to 140MB/s, C10, U1, Full HD, A1, MicroSD Card - SDSQUAB-128G-GN6MA [New Version]

It’s running on a new Pi5 with 8gig memory. It has a lot of free space, as it was not an upgraded OS, but built clean off of raspianOS bookworm using the guidelines (I then moved my previous config files over onto the new SBC.).

Firmware 3.5.1 was running on this SBC without an issue.

I’ll check on the debug setting. There’s nothing else running on the SBC.

I have a dedicated meanwell PSU for the Pi5, and voltages are spot on, and ample amp supply for it.

Things were fine before I updated to 3.5.2, now I can barely get through homing the printhead before it fails.
I am on "Bookworm"

@dc42 I just had another out of memory occur related to the tool board - I have this patch applied (actually a more recent one I believe), and it ran out again.

undefined

I had a reset as well, this one ANOTHER out of memory fault tied to the tool-board/CAN bus. It's at the point I can't do any large prints without the machine resetting half way through and wasting filament. Incredibly frustrating when you have it running 1-2 days only to quit on you before it finishes.

@droftarts I'm using an SBC

@chrishamm I see this on Safari and also on firefox. The firefox browser is on a PC, safari on MacOS. Same things on both.

@chrishamm, do you mean my config.g?

I see this on my screen...

on the dashboard I see this....

the pulldown shows this....

I noticed with 3.5.0-B4 the bed temperatures available for the bed presets are the same as the toolhead(!!!!) not the ones that are in the settings under "machine specific."

I certainly hope that no one can actually set their bed temperature to 270c.

This is new; it wasn't an issue prior to the beta update.

@dc42 switching to ei2 has led to successful print completions. Thanks for the work around suggestion.

undefined

@dc42 said in 3.5.0-B4, having random CAN error timeouts:

zvdd

Thanks, I'll switch to ei2 to see if that helps. I looked at the issue info you created - an added note, I am in fact using a raspberry pi 4 with this.

currently all I have on the toolboard are, extruder, fan, heater, and temp sensor.

undefined

@dc42 Actually, this was different gcode (but far simpler - just two rings out of TPU). Here's the gcode for the file that generated the error....

two rings

Once this happens, a lot of things occur. I have a expansion-disconnect.g file that I set up to capture the info. I get this:

6/19/2023, 7:20:14 AM 	Error in start-up file expansion-reconnect.g line 8: M562: Board 20 does not have heater 1

The contents of the expansion disconnect.g file is:

M25
M114
M562
M122
M122 B20
M0

Once the fault happens, it can't see the heater that's on the toolboard, so it can't be reset for the heat fault that registers because the CAN connection failed.

undefined

@deckingman It's really strange. it's ONLY this one file that causes the CAN timeout. I've printed now, 8 files, some smaller some larger and move complex with rapid movements, and none have caused the error this one file does. I narrowed it down to where it might happen in the gcode, but nothing looks odd. (Z3.4-ish) in the file. It's frustrating, as this is the last part I need for a project.

Maybe you guys can discover something in it. - problem gcode?

undefined

@dc42 it’s still failing, but I again neglected to check the lights. This time the tool head will continue to move, with the fan on, but the extruder temp reports 2000c and goes inactive, but continues to make the position moves along all axis. This appears to be happening at about the same point in this particular file. I have printed other files as a check, and they seem to work fine. The point of failure seems to be approximately where a support skin is formed and is about to make the first parts skin on top of that, meaning that separation layer where a bond is to be weak or non existent (I assume why the fan was on). Before printing I had redone an auto tune which was successful.

I did not get any can disconnect messages.

undefined

@dc42 It's consistently happened only (so far) with this one print. I have since it occured, printed other things successfully now. It IS a long print (11 hours). Everything goes back to normal once I reset.

I'll try again and if it fails, I'll look for the lights status.

undefined

BTW this is the error messag on screen when it now reports a temp fault

M562 P1
Error: M562: Response timeout: CAN addr 20, req type 6013, RID=382

undefined

and it's getting frustrating. I was able to do a M122 on the board, but M122 B20 (for the toolboard) results in no communication once the error happens.

Below is the M122 report.... @dc42... help
