Duet Web Control 2.1.1 released

chrishamm

I'm happy to announce the release of DWC 2.1.1 with a couple of bug fixes and full support for the new object model that RepRapFirmware provides. It can be obtained here: https://github.com/chrishamm/DuetWebControl/releases/tag/2.1.1

Please use this thread to report issues if you encounter any DWC-related problems.

Users of DSF (Duet 3 + Raspberry Pi) should wait until it is made available from the Duet package feeds. Testers using the unstable package feed can install it by performing a regular system update.

Just updated to DWC 2.1.1 and found out that the "Turn everything iff" - Button is not working. The following error is shown in the browser console.

I'm not familiar with the object model, so I don't know if this is a bug with DWC 2.1.1 or a bug with RRF 3.0.1RC6 (on the duet3 board.)

My part cooling fan is configured as:

M950 F0 C"out3" Q15000
M106 P0 C"berd-air" S0 H-1 L0.25 X0.6 B0

The "X" parameter seems to be breaking something with DWC. It specifies that the max speed of the fan is 60%, and RRF (properly) modifies any S parameter to fit within that value. (So S128 would set an actual speed of 30%, S255 would set an actual speed of 60%)

When the fan is turned on to "100%" (M106 S255 - which is actually 60%), my PanelDue properly shows that the fan is at 100% and I can change the value (which is properly scaled as described above.) However, when the fan set to 100% (S255), DWC's fan slider is showing 60%, and won't allow me to change the value. Neither the slider nor +/- buttons work. If gcode sets the fan to half power, the PanelDue properly shows "50%", but PanelDue is showing 30%.

If it helps, M409 k"fans" has the following (partial) result when the fan is set to 100% (but limited via a X0.6 param)

{"actualValue":0.60,"blip":0,"max":0.60,"min":0.25,"name":"berd-air","requestedValue":1.00,"rpm":-1,"thermostatic":{"heaters":[]}}

So, my guess is that DWC is displaying the 'actualValue' instead of the 'requestedValue'. As for why I can't change the value from DWC, I have no clue.

This worked properly with DWC 2.0.7.

@chrishamm
I noticed that M122 is broken in the Console. If I type a M122 nothing is displayed.

On 2.0.7 it is working fine.

I'm having a problem with the parts fan slider not being displayed on the Status page.

I'm using a Berd-air pump as a parts fan connected to the E1 heater output. Previous versions showed the fan slider on the Status page. With with 2.1.1 it is no longer displayed.

The config.sys line is:
M950 F0 C"E1_HEAT" Q15000

However, if I change M950 in config.sys to:
M950 F0 C"FAN3" Q15000
the fan slider is displayed correctly in 2.1.1

@insertnamehere I had this also on my duet 2. I now upgraded to RC6 and it is working fine

I'm another with a fan thing happening. Using the laser/servo pwm with a blower on a Duet 3 for part cooling and the blower works as intended, but displays as 0 speed in DWC during a print.

M950 F1 C"out9" Q25000
M106 P1 C"Partcooling" S0 H-1 B0 X0.3

With regard to the fan being missing form the DWC, I too found that initially.
However it was simply hidden and had to be re-selected for display.
It functions normally.
See progression shots.

@OwenD Unfortunately that's not the issue, at least with those of using using slightly odder part cooling.

More information in general for what's happening specifically for me;

When I call a fan name in M106, the slider is in DWC while not printing, but doesn't actually do anything. When printing, the part cooling fan works as it should, but the slider sits at zero unless I touch it (and I do then have control), until the gcode changes the fan setting (at which point the slider stays where I put it and the fan changes to the speed the gcode called for). In this instance, the option for Tool Fan and the same fan as the name I've set in M106 are available.

If I remove the fan name from M106, it is not available while not printing at all (and neither is Tool Fan), but it otherwise functions the same during a print (Tool Fan becomes available).

If I run M106 P1 S0.5 while not in a print, it does work.

edit:
After updating to RC6, the functioning slider is back while not printing, but it's displaying the pre- X value set in M106. In my case, X0.3 and setting the fan slider at 50% will cause it to snap back to 15. Using the + and - buttons is sort of fruitless unless you click really fast.

Thanks, I just needed to update to RC6 and it works now.

@garyd9 @PaulHew Thanks for reporting these issues! I'll fix them in v2.1.2.

@chrishamm And fan sliders do not work or indicate current speed.
Sorry.

DocTrucker

Version 2.0.7 ran fine on v0.6 and v0.8.5 boards. Is version 2.1+ dependant on using RepRapFirmware 2+ or 3+?

jay_s_uk

@DocTrucker

Its dependant on RRF3.01+ as it uses the object model

DocTrucker

@jay_s_uk cheers, that's what I expected but I wasn't sure if it used the object model it available, or exclusively. From what you say it is the latter.

Found this this morning.

'Turn Everything Off' does not do anything.

FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 3.0 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2020-01-03b3

Also strange is that with a dual set-up the loaded filament is moved from T1 to T0 and cannot be unloaded.
(To be clear, T1 has a filament loaded, I do a pause, then immediately a cancel and suddenly T0 is loaded with T1 filament and that cannot be loaded to T1 again and T0 does not what to unload it. Temp settings is still on as espected on T1 (old temp) and t0 also as before...)

I had to delete the file "filaments.csv" and do a "EMERGENCY STOP" to get T0 to relese the T1 filament...

I think this happen when I cancel a print...

Which I do a lot since I try to get my filament to stick.
Would be nice to be able to cancel directly and not need to pause and then cancel...

This time I do not see the "filament.csv" so I pray to god that a power on of cycle get my printer back...

I did... the file was not shown until I made a power on/off cycle.

That would be nice if it did.
I also do not understand why the file "filament.csv" kept after a power cycle? At least a forced unload feature would be useful...

GrodanB

For some reason I cannot change the wording mistake I did above (someServer.com identified post as spam)

So a power OFF/ON did work...
