It's out! RepRapFirmware 2.0 and 1.21.1 released

[demonio669]

dc42, what happens if you have a 0 bytes config.g ? should the firmware run config.g.bak ?

I have several times a 0 bytes config.g after power-off cycle

[BMMal]

To expand further on my issue of not getting responses, it seems that DWC is somehow getting out of sync but not disconnecting ie, a print was started and it did not automatically go to the Print Status screen. DWC still indicated that the machine was connected. I made a change to config.g, the file got updated (confirmed by looking after saving) and DWC asked if I wanted to reboot as if the machine was not printing even though it was. Manually going to the status page, it did not appear that the machine was printing. Refreshing the browser did however update properly.

Hello

little Problem with
Web Interface Version: 1.21.1
there is only 1 Fan slider
on 1.21 you have sliders for all 3 PWM Fans (if activated)

thanks

@dc42 I got my install working perfect now. I tried taking the SD card out a few times but that made no difference so I copied the firmwares to my SD card and activated the installs with my PanelDue. It worked great that way. No need for USB interfacing.

On a side note I did notice when I was having my issues with the first install I saw that the blue LEDs were lit up in the Wifi module but not blinking and they were barely lit. If that means anything?

I must have gotten a bad install on one of the firmwares the first time but all is well now.

Thank you for the help!

Using it on WorkBee since released. No problems so far!

I have some Duest 06 that I'm still having the same issues with as was mentioend previously in 1.20 with regards to not using static IPs (https://forum.duet3d.com/topic/3508/firmware-1-20-released/75).

To confirm, if a static IP isn't provided using M552 then the Duet will work fine and can be controlled over USB and/or a PanelDue as long as the ethernet is disconnected. Before plugging in the ethernet, this is the output of M112:

Shortly after, however, everything locks up and neither the serial over USB or PandelDue respond. After unplugging the ethernet, and waiting a short while (without power-cycling or resetting) I can issue an M122 again, and this is the response:

I have just tried the same on an 85 board and can confirm that it does the same. Dropping back down to 1.19 makes everything work again (minus the new features ofc).

With DWC 1.21.1 and RRF 2.0/1.21.1 you are able to control all fans that are not set up as thermostatically controlled.

Below are two config file from two very different printers one uses an 06 board, the other uses an 85 board - the problem on both boards is the same. With any FW later than 1.19, the ethernet connectivity is broke. If a static IP isn't specified then the board constantly boot loops. If a staic IP is defined, the boards will boot but I still can't access the web interface either by printer name or IP.
The first is my own printer that I often take into work and use there. Its a pretty standard setup and uses the 06 board with a PanelDue:

@knaudler you could edit DWC to change this, but by definition seeing the fans does not give you control of them because they are controlled by the temperature of the hotend....

[wilriker]

I had a strange issue today while printing. Somewhere in the middle of printing layer 1 I used baby-stepping to raise Z by 0.025mm. And about 40s into layer 2 I undid that again. And now this might be coincidence but at about the same time DWC reported a switch from layer 2 to layer 3 (layers 1 to 4 were supposed to take about 10-15 minutes each) and reported layer 2 with a total time of 40s.

Now my print does have a shifted layer (again might be coincidence with bad first layer adhesion as another rather probable reason). I cannot tell if that really is layer 2 to 3 (it rather looks like layer 2 was shifted to the left compared to layer 1 but I cannot tell for sure - and as I was controlling the printer from remote using webcam to only check sometimes I don't know for sure either).
I looked at the Gcode and layer 1, 2 and 3 have about the some amount of lines which means that part is OK.

I will have to print that part again and will see if this happens again. Definitely never had something like this before when using baby-stepping.

@t3p3tony

hi
using fan 1 for hotend cooling
starting at 50 degrees - at 80% (have 15v input)

sometimes - if I want higher temps - 250 degrees - I push the fan to 90-100%
or if I need only 190 degrees - in the night, for extra silence - go down to 70% fan, thats ok

the only sound of the cr10 now are the fans

would be nice for me to controll all fans

thanks

One workaround would be to create a few macros to set different speeds for the hot end fan.

I don't know if you are aware of this but you can use thermostatic control to vary the fan speed over a range of temperatures which might achieve what you want automatically when you change the hot end temperature. This is what I do but in my case I just use zero speed below 60 deg C and full speed at 140 and above. In your case you could use for example M106 P1 S255 I0 F250 H1 T50:250 would give (if my maths is correct) zero speed at 50 degrees C and below, 70% speed at 190 deg C and 100% speed at 250 deg C. You might need to play around with those values and there is also an "L" parameter to set the minimum fan speed which you could use to give a non zero speed.

[Knaudler]

thats a good idea
I will test.

thanks

[otaku521]

is it just me... or if you have the web interface running on screen for a long time it is out of sync with the current status (I tell by looking at current z level location)

I had my big print on for a while and it tells me that I am at Z@ 11.xx but when I refresh the screen it is now changed to Z@17.xx

I never noticed that with the previous version

Thanks
Tony

[SM3D]

@otaku521 I too face the same problem - web interface shows a different value and I have to refresh the tab to see the current value.

In previous versions, it is either connected or disconnected. When it is connected, it is in sync with the actual print progress.

Cheers,
Vasan
