Duet 3 6hc + SBC just stops printing

Stephen6309 · 22 Aug 2020, 14:37

Today, it's once again dying on the second leg of the skirt.

Wrapped the ribbon cable in aluminum foil and grounded it. No change. Disconnected the pi touchscreen.

It appears my pi4 stops talking to the duet 3. Emergency stop restores the ability to send gcode.

Going to see if the 2020-07-20-DuetPi.img lasts longer. It's current printing. Now, will it keep working over the next few days. Ribbon cable still shielded. Didn't do the updates yet.

Next time I'll try the direct connection.

I have been using a Pi-3B+ on my duet 3 Unit with NO issues, maybe its a Pi-4 thing, latest is not always best...

Can you provide M122 results after the stop?

Or enable the monitoring I linked above?

Stephen6309 · 23 Aug 2020, 12:32

@Phaedrux I will try the debug mode again, if it does it again.

Running a similation of a print has worked fine.

Stephen6309 · 23 Aug 2020, 14:05

@Phaedrux 2020-07-20-DuetPi.img smae thing happens the next day. Tempertures still update, can set them. Simulating print time was completed successfully.
Emergency stop restores movement.

Will try to set debug. Stop the servers, and the first command in PuTTy:
sudo /opt/dsf/bin/DuetControlServer -l debug
Stops after showing: Updated key volumes

VNC Connect will not connect, via IP or CXY-MSv1.local.
Used Advanced IP Scanner to verify IP.
Connected the touchscreen: desktop screen garbled.

The M122 is below.

Did the update and upgrade. That took a while. The update let me set the resolution for the touchscreen. Started print via touchscreen. Stopped again.

Where is the terminal in 2020-07-20-DuetPi.img?

Ther M122 doesn't change, except for the bytes transmitted/received.

Pulled the 5vdc to Pi jumper and tried powering the pi4 from a wall wart, no change.

Stephen6309 · 23 Aug 2020, 15:25

Tried a new setup on a different card. Can't connect to the Pi4, DWC or PuTTy doesn't connect. Put other card back, it connects, but won't keep printing. does show a low voltage on the screen just before to showes DWC. Tried the Pi0W again with the 2020-07-20-DuetPi.img, didn't connect.

Next: direct connection, it works.

Looks like my Pi4 is flakey, need to get another one. Will know for sure in a few days.

Stephen6309 · 25 Aug 2020, 12:57

@Stephen6309 So far, the direct mode is still working.

Stephen6309 · 12 Sept 2020, 14:40

Update: Got a new Pi4 from Adafruit with an acrylic case. Installed DuetPi OS with GUI and a fanshim. So far it works and seem to be a bit more responsive. Printed a magic fish just fine.

In a few days, we'll see if it stays working

Stephen6309 · 15 Sept 2020, 13:29

It's still printing.

Stephen6309 · 17 Sept 2020, 14:58

Spoke too soon. It's doing it again. Going to ask for a new ribbon cable.

Filastruder needs authorization for a replacement cable.

Approved.

Stephen6309 · 4 Oct 2020, 13:30

Received new ribbon cable, installed last Thursday. Worked fine Thursday and Saturday. Today it's once again stopping during the skirt. Emergancy stop needed to get any axes to move. The ribblon cable wasn't the problem. Can run in direct mode with no problems.

Disabled the write buffer:

@dc42 Looks like the problem is with the Duet 3. M122 in prior post.

@Stephen6309, thanks for your report. Please try release 3.2beta2 which we plan to release later today.

Stephen6309 · 6 Oct 2020, 17:52

@dc42 I've installed it. It's currently printing, but problem usually has taken a few days to show up. Will update later this week.

Stephen6309 · 10 Oct 2020, 14:21

@dc42 So far, it's working fine. Had to change to my BLTouch v3.1 from the first original version.

@Stephen6309 said in Duet 3 6hc + SBC just stops printing:

Thanks. What was the problem with the older BLTouch?

@dc42 It would do a double tap on the bed. It would do it when homing Z, and doing the G29.

Watching it do it, the moment it would hit the bed, it would fully retract, but it would imediately redeploy and trigger again.

Watching the 3.1, it would trigger and not rectract completely, the full retract was delayed,
