Firmware 2.0RC2b/1.21.1 RC2b released

[Dr_Ju_Ju]

Updated successfully with no problems, but I'm having issues while printing (multiple times via USB or local gcode), in that 1\2 to 3\4 of the way through a print, I get "Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C".

This results in two conditions, a local print, parks the toolhead to XY cordinates shuts off Bed & halts the printer and errors with Resume-after-power-fail state saved.

If I'm printing from USB (Simplify3D), when the failure occurs, S3D knows somthing has gone wrong, but the printer keeps on moving, and keeps the bed heater running, but is unable to extrude.

I accept that printer won't know what is being printed, but should the printer do a hard re-set on hard error to at least kill all running prints ??

I was\am attempting to print ABS parts for Panobot on DBot 300x300x300 coreXY printer, driven by a DuetEthernet, so using Bed 110 Hotend 255.

I've chased all the wiring\checked all connectors, at various points around the bed area, bending strains are reduced as I'm using cable chains.

I'm almost at the point where either the problem is on the Board or the heater cartridge (E3D).

Next chance I get I'll re-map the heater to E1, if that fails to fix it, I'll replace the cartridge. But its strange that everything works fine for long periods of time, fails, & the one time it has happened while I was near, a board re-set let it resume.

I've just completed a 10.5 hour print on this release without issue. It appears to be stable with the exception of the weird simulation hang. After a hard reset, the simulation ran fine.

Does Duet actually choose the correct firmware version automatically? I actually went out of 1.21.1. Now I have 2.0, or have I selected the wrong file?

M502 now resets all firmware parameters back to the values in config.g except network parameters

Are there any other exclusions or only one?

I get this message, is this correct?

FWIW after upgrading I also experienced the heater fault issue; 4 times on an 8 hr print. Probably just bad luck with a loose connector, as after a reset and restore the print started right back up, and I didn't have the heater calibrated either, and I had seen this happen long ago too. Simulation worked fine with the updated PanelDue and it would be amazing to see the simulation done as a parallel thread to calculate upon print start. Originally had an issue with losing the web interface, but copying over a new web directory solved that.

Saw a small improvement in WiFi transfer; now close to 500 KB/s, up from about 400 KB/s.

Good work!

So far the new firmware and DWC work great. Love the ability to upload files while homing the printer.

A good test will come tonight, Ditto printing (IDEX) on a 8 hour print run.

[BMMal]

I've been using this since it was released and have not noticed any issues yet.

[timcurtis67]

Last night While printing a long running part, I uploaded a 17mb file at speeds of 700KB/s with no issues.

Well done David!

I installed RC3 (or RC2b) and printed a couple of small things (~2 hours prints each) without any problems.
The baby stepping command seems to be responding a bit faster than before

Hi,
I am using RTOS version and generally no problem. Today i add relay unit for controlling 24V line (M80 and M81).
It is work but when i first start the printer 7" Panel due still connection state, if i send M80 from DWC then paneldue's state change to idle. After that paneldue can send M80 and M81 without any problem.

Is this firmware problem or i made any mistake?
Thanks,

Did a run on WorkBee with 2.0RC2b and the part was identical to the one machined with 1.21.

The PanelDue firmware needs to be updated to support the new Off status returned by the firmware when VIN power is not present.

Hi,
Thank you for your answer, tomorrow morning i will check it. Which version it should be?

[dc42]

The version that hasn't been released yet!

Have now printed long-ish (couple of hours) and very short (10 minute) prints with no detectable issues. This is on the large-ish custom delta (600x600x600) at 24V with separate mains heatbed.

Thanks to all of you who have provide feedback on RC2B. I'm looking to fix a few old bugs before the 2.0 release, so there will probably be a RC3 next week.

I've now had a chance to swap Heater 1 for Heater 2, which has appeared to have fixed my issue with heater crashing & failing print, but it does mean the a board I bought in early January has problems (when I got the board, there were unsoldered joints !!).

One issues I have with this is that the Web interface works as expected, but the PanelDue still shows a "phantom" heater H1, with Current\Active\Standby boxes as well as the re-mapped heater as expected.

If you believe your Duet was delivered and still is faulty, please ask for it to be replaced under warranty.

@dc42 I've flipped it back to H1, & started a long'ish print, just to confirm that it still fails. If it does, I'll request a replacement, but at least it looks like the wiring & cartridge etc. are all ok

I "may" have found my issue, as although I have an 80mm fan mounted under the duet board, and its enabled with:
M106 P2 S0.5 T55 H100:101:102 ; Set fan 2 (Duet Board) to come on half power if any driver chip reaches 55 degrees
it has not been coming on with this firmware ?? and some of the ic's including the heater power mosfet have been getting very hot to the touch.

It used to work fine with the release firmware, but I don't know if anything has changed ??

As I'm in the middle of a long print, for a stop-gap I've carefully sat a 40mm fan on top of the wiring from the drivers, driven from one of the "always on fans", which is keeping everything cool.

I'll investigate further when the print completes (hopefully).
