@chrishamm - OK, I'm sorry, I overlooked it.
Thanks

Thanks @jay_s_uk. What is the process to update mini5 from 3.3 to this beta? Is it explained somewhere?

jay_s_uk

@zapta are you in standalone mode or SBC?

@chrishamm
Thanks for the firmware update.

For information as per the last b4 update I had to use a USB connection and double tap the board's reset to upload the firmware directly to my D3 Mini's bootloader area. Uploading via DWC didn't work. I also tried forcing the update with the relevant M gcode command.

I'm wondering if I ought to create a clean build of my SD card in case something has got corrupted?

All the best

@zapta as @jay_s_uk said, download the appropriate upgrade files for your board. In your case, assuming standalone, download Duet3Firmware_Mini5plus.uf2 and DuetWebControl-SD.zip then upload in DWC. DWC should prompt you to install them.

If you're using an SBC, you need to be on the unstable package feed, see https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Software_Installation

Thanks @droftarts , yes, standalone. I will give it a try.

The official firmware upgrade documentation mentions .uf2 only in the context USB based update.

@chrishamm 6HC & 1LC with PI4. Using Putty. It got stuck on updating mainboard firmware from beta4. Diag led on, no flashing. After waiting several minutes, I reset the board, diag led started flashing. No response from printer, then I shutdown the printer, fired it back up and beta5 was installed and diag led was flashing. Then I did an emergency stop to get the 1LC working.

As of 3.4.0-b5, "M0 Hnnn" is still turning off the heaters.

@oozebot from 3.4 onwards the "H" flag is not longer used. However an empty (but present) stop.g file should mean no action is taken when stop.g is called. This allows for more nuance in which heaters are left on or switched off based on what you have in stop.g

That said I have just confirmed that an empty stop.g does not prevent the heaters for being turned off so this still needs to be resolved.

We are still experiencing random chamber heater faults on 3.4.0-b5 when heating from room temp. I don't think we can tweak our M307 further.. We never saw this prior to the 3.4 betas.

Error: Heater 2 fault: temperature rising much more slowly than the expected -0.0°C/sec

@oozebot is there much noise on the temperature reading? What temperature sensor are you using? From the message it appears that RRF is recording a temperature drop.

@dc42 The chamber heaters do bounce around when heating up initially from room temp. To compensate, we've dialed our M307 back to next to nothing. As for the the probe, it's just a run-of-the-mill B3950 thermistor.

M307 H2 B1 C1800 D350 R0.02

The temperature can and does swing negative while initially heating. Some of these faults may be due to momentarily opening the doors to the chamber while heating, but more often than not, the faults occur when the printers have not been touched (and the doors are closed).

We understand the importance of faulting a heater when it's too slow to rise (ex: leaving the doors open), but really would like to see the parameters relaxed while initially heating.. unless there is something more that you can suggest with our M307?
