RepRapFirmware 3.01-RC6 released

[Danal]

Correct. DC42 is the primary (but not only) author of the firmware for the Duet Board itself, and is the lead engineer for the company, and a principal owner of the company.

Chrishamm is the primary developer for Duet Web and for Duet Software Framework on the Pi. I do not know his other relationships to the company. Chris has the hardware to test D3+Pi.

And... anyone can open a "pull" request, it is the nature of github. So there are somewhere between 7 and a dozen other contributors. Probably not all that relevant to our discussion here.

I just installed 3.01 RC6
I have run into a couple of issues and I'm not sure if it is the firmware or the web control...I also updated it to 2.1.0

1. I have a load filament Macro and when I tried to use it it did not function...it is pretty simple the extruder was up to temperature
   M83
   G92 E0
   G1 E1200 F3000
   G1 E200 F10
   Also on the same note if I try to press the extrusion control from DWC it does not work either but the funny thing is that if you do it on panel duo it does work.
2. on the tools block when extruders and bed are on and you go to the control all and press turn everything off...that does not function
   It will work if you change the set all active temperatures and set all active temperatures to some other value then back to 0 again

@chas2706 said in RepRapFirmware 3.01-RC6 released:

In a previous post somewhere I read that @ DC42 does not have Duet 3 with SBC so based on this how can new firmware be released if the owner of firmware does not have the hardware?

i get thats its frustrating when things go pear shaped; and I don't have an explanation as to why I was able to downgrade to a specific version but you were not - however it does suggest something being amiss with your setup.

if you still have a backup sd card, I would encourage you to make a copy and then try that with my suggestions for restoring the RRF firmware which is on the sd. there really is no reason that shouldn't give you the same combination of apt packages and rrf firmware as you had when you made the backup.

seem to be working on duet2eth but when I upload Duet2CombinedIAP.bin in the system tab it shows uploading forever, never finishes?!

[Marco Bona]

I updated the DWC to 2.1.0, but I haven't noticed any changes.
Yesterday I tried to make a couple of prints but the layer screen remained with the same problem I had.
It always hangs on the second layer and the statistics are wrong.
This morning I try to start the print and see if something has changed.
I'll update you as soon as possible.
Thanks

I'm sorry that there are some issues with upgrading to the new RRF/DWC/DSF. There have been many major changes, especially to DSF and DWC which now support almost the full object model.

Here's a summary of issues we are aware of with upgrading to RRF 3.01-RC6, DWC 2.1.0 and DSF 1.3.0.

1. DWC issue: extrude/retract buttons greyed out when they shouldn't be. Workaround: if you need those buttons, use DWC 2.0.7.
2. DWC issue: when you click on a heater in the Fault state there is a new dialog that allows you to reset the fault; but the heater fault reset doesn't work.
3. Upgrading RRF+DSF+DWC on Duet 3 with attached RPi does not always go smoothly.
4. DSF issue: laser and magnetic filament monitors without a filament present switch are not handled. Workaround: add 1 to the filament monitor type (M591 P parameter) to say that a filament present switch is present, and put a jumper across the filament present switch pins to simulate the presence of filament.

We are preparing a new DWC release (2.1.1) to address #1 and #2, and a new DSF release (1.3.1) to address #4. Chrishamm will provide new instructions to address #3. I will then lock this thread and we will start two new threads: one for issues users are having using the new release on Duet 3 + SBC, and one for other users.

[gruen]

for me work this to upgrade my sbc:

apt remove duetsoftwareframework duetcontrolserver duetsd duettools duetwebserver duetwebcontrol reprapfirmware

and install with

apt install duetsoftwareframework duetcontrolserver duetsd duettools duetwebserver duetwebcontrol reprapfirmware

[Marco Bona]

@droftarts, I send you the DWC screen, as you can see nothing has changed since the previous build.

The only doubt is that there is something at the beginning of the file that creates some noise.

@Marco-Bona can you confirm you’re using the latest firmware and DWC versions? Shown on System tab of DWC. I have not had a chance to test if the layer time problem is fixed.

[Marco Bona]

@droftarts, I confirm, I am using DWC 2.1.0, I have updated to RRF3.01 RC6 and DuetWiFiServer 1.23.

@dc42 thanks for your clear statement. have a nice weekend.

[ChrisP]

@dc42
I've just stumbled across another odd error.
I had just started a print but a bit of purge material got caught on the head so I paused the print (I have a hardware button and use the input to trigger a pause using M581).

On first press of the button, all motion stopped instantly but the pause script (below) wasn't executed. I pressed the button again and the notification to say that the print had been paused be external trigger showed but the head still didn't move out of the way.

; Pause macro file
M83			; relative extruder movements
G1 E-3 F2500		; retract 3mm
G91			; relative moves
G1 Z10 F5000		; raise nozzle 10mm
G90			; absolute moves
G1 X0 Y110 F5000	; move head out of the way of the print

I then pressed Emergency Stop on the web interface at which point the web interface said it was tying to reconnect, but it never came back to life. I tried moving the axis by hand to move the hot nozzle off the print but all the axis motors were sitll powered and holding. I took the following dump fron the DCS service log on the SBC:

I pressed the reset button on the Duet3 (by the power LEDs) and everything came back to life. I've since tried to recreate the issue, but can't unfortunately as yet.

The printer has been running solidly for days, so I'm not inclined to believe its a hardware or other setup issue at the moment.

update:
I've not just had it crash randomly mid-print. Web interface becomes unresponsive and service logs are full of:

Apr 04 12:03:53 starttex DuetControlServer[360]: [warn] Bad data checksum (expected 0x92b3, got 0x23e3)

I also seem to be getting lots of this. Which is confusing as I don't have the macros page open on anything...?

[chrishamm]

@ChrisP It looks like you have a PanelDue connected to your Duet 3 and that is not fully supported yet while the Duet 3 is operating in SBC mode. At present the only transmitted command from the firmware to DSF is M20 which you can see in the logs. So I suggest don't use the PanelDue for anything else than pausing prints (not resuming) or emergency stops in SBC mode until support for PanelDue has been fully implemented.

Can you share the output of M122 if you are certain the firmware reset unexpectedly?

[ChrisP]

@chrishamm
You are absolutely correct that I have a PanelDue connected I hadn't anticipated that this could be part of the problem since i'ts been connected since it has always been connected to the Duet3 from the first time I set it up over a few weeks ago. I was aware that it had limitations but have kept it there as an easy way to view teh temperatures and print progress - I don't use it for anything onther than displaying info currently. With previous firmwares / DCS it's been operating fine. That said, I'll take the advice and remove it for now.

Is there a was that I can issue M122 and grab the result from the Pi as when the crashed happen, the web interface becomes totally unresponsive and requires me to press the hardware reset on the Duet3 to bring things back to life?

edit: I will unplug the PanelDue, power cycle and try the print again.... I'm only running test prints currently to ensure the system is stable... clearly not quite ready for a proper print yet

[chrishamm]

@ChrisP It sounds like there is a problem in DCS and I'll be happy to look into it. To obtain some debug info, please connect to your Pi via ssh, run sudo journalctl -u duetcontrolserver -en 100 --no-pager, and share the output you get.

PS: It's fine to leave the PanelDue attached but be aware that most file-related commands will not work as expected.

log in using ssh and do echo M122 | sudo /opt/dsf/bin/CodeConsole should work if DuetControlServer is still running, if that is not the case, you'll need to connect to the Duets micro USB port and use it as a serial console.

Thanks for the help. I'm running this as a test machine anyway, so I'm happy to test anything on it if it'll help move forward. Here's the log from a fresh boot (with PanelDue disconnected):

@ChrisP Thanks, please run that when DSF becomes unresponsive. So far nothing unusual in this excerpt.

Is there a was that I can issue M122 and grab the result from the Pi as when the crashed happen

log in using ssh and do echo M122 | sudo /opt/dsf/bin/CodeConsole should work if DuetControlServer is still running, if that is not the case, you'll need to connect to the Duets micro USB port and use it as a serial console.

Don't know why I didn't think of the USB console - this is how I always debug 0.6 and Duet 2s... duh! Interestingly, the service dump mentioned a depreciated firmware, so here's the M122 log that I hope shows this isn't the case...

this is how I always debug 0.6 and Duet 2s

easy to loose sight of the trees in the forrest i guess

timeout 1 cat /dev/ttyACM0 & echo -e "\nM122" > /dev/ttyACM0

should get you the M122 from serial as a one line copy/paste if you should need it (as opposed to installing the less than user friendly console based serial terminals available for the pi)
