@T3P3Tony Yes. I have since disassembled the printer and reassembled it. The crashing seems to be resolved. Mind you, I could go several months without a problem.

The board just seems to be acting strange. Either the board or the firmware.

I am also having a similar issue. I am on 3.5.0 b4. Uploading files is hit or miss. DWC will disconnect and refresh. If I keep retrying it will eventually work. The larger the file, the more I need to retry. It was fine when I was on 3.4.5. I upgraded firmware to address other issues.

Running 3.5.0 rc2 causes layer shifts when using input shaping so upgrading is not an option

@gloomyandy I have no additional boards connected to the 6HC and nothing plugged into the RJ11 connector. Here are two pictures of the board:

I am having strange disconnects as well when uploading files. I spoke with another person on the Railcore Discord server and they are having the same issue. They said, and I quote, "When uploading g code files to my duet3 connection is lost. The larger the file the larger the chance that connection is lost during upload. Using a wired connection directly to the duet."

I am doing the same thing. I had a keystone hack mounted on an external panel. I bypassed that and plugged straight in and it still had the issue.

@dc42 I do not have a PanelDue connected. Also, I don't have any second boards connected. I downgraded to 3.5.0-beta.4 which seemed to resolve the layer shifts, but the errors and connection issues persist. If I keep retrying it eventually goes through. The larger the file the more I have to retry.

This is the log after a reset, boot up and then home all:

Sorry to resurrect this. was there every a resolution to this problem? I am running into similar issues. I am also showing tons of errors on CAN. Here is the diagnostic after a skip log:

I am also having issues uploading files. I switched SD cards and the problem persists. Sometimes they will upload but I have to keep retrying and eventually it uploads. I can still ping the IP when it disconnects.

I don't know if my board is on the way out or what. It has been nothing but problems over the last 2 months. I recently disassembled the entire printer and reconnected everything. My random crashes have stopped (for now) but these other issues are getting worse.

Here is my config:

	global materialtype = ""
if !exists(global.materialprint)
	global materialprint = ""

	global materialbed = ""
if !exists(global.machineheater)
	global machineheater = 0
if !exists(global.inFilamentError)	
	global inFilamentError = false

I am tempted to ditch the Duet 6HC at this point. It is crashing constantly and I am wasting filament. I took the entire carriage apart and reassembled it being sure to check everything over. I have verified ground on the hotend and disconnected the chamber thermistor in case that was causing issues.

What else can I do short of replacing the entire board?

Well, another crash. This is after 2 or 3 multi-hour prints finish successfully. The most recent print went for a little over an hour and then crashed. I am nearing my wits end and not sure what to do.

I unplugged the filaments sensor to see if that was causing issues. It still crashed. I have now removed everything not essential to printing.

@dc42 Thank you for the heads up. I will continue to post crash logs as I receive them. I suspect mine is related to a hardware issue and static. I was on 3.4.5 and it was crashing with the same type of error.

Initial testing after moving the chamber thermistor is promising. I was able to do 2 successful prints that were 3 hours long.

Is there a way to ground the thermistors on the Duet side in order to protect the board? I'd rather wire something in if it all possible to eliminate that as an issue. the hotend thermistor has a metal enclosure and is grounded by the hotend. The other thermistor is bare with just the two leads going to it. I am not sure if it is acting as an antenna for static when it is near parts interacting with filament or what. I am really just shooting in the dark as this point.

@droftarts The long road to troubleshooting an intermittent problem is a long one. I am wondering if my chamber temp thermistor is collecting static. It is unshielded and very close to the hotend. I am not even sure if that is possible.

I have moved it away from the hotend for now to see if that helps.

Here is the config.g

;Initialize variables

	global materialtype = ""

	global materialprint = ""

As for the printer, it is a Railcore II 300ZL corexy. The hotend is a Phaetus Dragon with an Orbiter II extruder. LDO steppers all around with a 750w heat pad on a magnetic bed kinematically mounted. The Z probe is a Euclid.

Another thing I did today was verify the bed has ground to the frame. The firmware looks like it is for the Mini+. I have a 6HC will that firmware work on the 6HC as well?

Its so strange because everything worked fine for months after the initial problem of random reboots. Absolutely nothing has changed except the weather.

Another crash...

So I've done the following:

Upgraded to firmware and web control to 3.5
Replaced the thermistor
Verified ground from the heatblock to ground on the Duet (Continuity check between Power In GND and metal of the heat block)
Printed without filament to verify its not a general issue with the board

I cannot reliably recreate the issue. It does seem ESD related, but I am not sure what would be causing it. Are there any steps I can take to narrow it down ? What else could be affected by ESD that would crash the board?

@chrishamm I verified continuity between the hotend and Duet ground. Are there any other methods to check to make sure it is properly grounded? I have another thermistor on the way just in case that is causing a problem.

So, several months ago I was having an issue with my printer resetting mid-print. I grounded the hotend and that seemed to solve the issue. Well, it is randomly crashing again and I have no idea what is going on. I verified the hotend ground and it is still fine. I am using GekoTek build sheets of which I used for 30+ hours of printing about a month ago. I also printed a few thing last week that were 3+ hour prints each.

Nothing has changed except the temperature around the printer. It is slightly colder here now that winter has settled in. The printer has not been power cycled since it was last used. Any guidance would be much appreciated. Here is the latest crash dump:

@dc42 running a dedicated grounding wire seems to have solved the problem. Do you have suggestions for other methods to ground the hot end or to isolate the sensor? Maybe how to integrate an ESD protection circuit with the sensor?

@dc42 Thank you for the information. ESD sounds like it might be the culprit. I switch my build plate to a PEI sheet yesterday and that may be a contributing factor. I was using Gekotek sheets for a while and never had an issue. I have made sure the nozzle now has continuity to ground and am testing now.

Are you aware of any other ways to insulate from static, specifically the temperature sensor? Having one more wire run in an already full loom is less than ideal. Also, the hotend is coated so getting a good connection is difficult.

My Duet 6HC has been randomly crashing. It ran great for a couple of years but about 6 months ago started crashing randomly. I though it was my smart outlet I used to turn it off and on. I removed that and it seemed to resolve the issue. Unfortunately, it started crashing again. Here is what I have done recently:

• Updated the firmware to 3.4.5
• Enclosed the printer so the chamber can be heated (passively by bed only)

Here is the latest diagnostic output:

I am not sure what is going on and any help would be much appreciated

If you are still taking orders, I would be interested in one. I was looking at building my own but don't have the necessary tools to make it easy.

Thank you for all of the help. Sending a PM to sort out the rest!
