Firmware 3.0.12-RC2 - MK2 Multi Material, MK2/S & MK1  

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

Hi guys,

MK2 Multi Material, MK2(S) and MK1 are supported! No printer is left behind. There is even a special build of MK2 Multi Material with older 10a Rambo in our test lab to ensure all printers are covered 😉

This ! This is what make you so special and awesome ! 🙂

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

I've started getting thermal runaway errors again that I hadn't seen for a few releases.

I've rolled back to May's MK2 release for now.

Anyone lese seeing this ?

Also - does a firmware flash loose PID calibration settings ?

Thanks

Hi, those runaway errors are random or in the same situation (heating up vs during print).

Let me know 😉

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

During Printing - I had them a few months back but some tweaks to the fan cowl and PINDA adjustments sorted it,

Rolled back one release to the May MK2 and they have gone away again ....

What kind of material and temperature settings are you using? I forwarded your feedback to the firmware developer.

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

I too got manythermal runaways on the heated bed, printing ABS at 100 degrees celcius. It started ok, after a certain time, the temperature was dropping. I checked the thermistor and the cable, cable was fine, thermistor was not loose. Sliced with Cura,

Please see enclosed picture. For now I am printing PET, at 90 degrees hotdbed temperature, no problems yet...

It was just stard PLA (rigid Ink) at 215

Its been fine and stable since the roll back

Guys thanks for the feedback so far, forwarded to the firmware development.

I've just installed the 3.0.12 firmware thats currently available on the main download page and I've noticed that the e-step value for the extruder isnt stored properly and constantly changes back to the firmware default. Is anyone else experiencing this?

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

Its removed.

Changes in 3.0.12 final:

MM: fixed bug with active beeper during filament loading
M500 gcode now doesn’t store Esteps value to EEPROM preventing weird behaviour when upgrading MK2 to MK2 MM

Maybe it can be put in the start gcode instead.

Re: Firmware 3.0.12-RC2 - MK2 Multi Material, MK2(S) & MK1

I had a problem with 3.0.12
After "pause printing" I try to resume printing, but nothing happen.
I realized after resume, target temperature was set to 0. State was heating (for hours) but printing has not continue.
For me it looks like a firmware bug....

Marcus,

Was this a pause from the front panel, or from OctoPrint? OctoPrint has a very short (10 sec) timeout set, and if it does not get a response from the printer (e.g. it is paused) it stops everything. Increasing that timeout will allow you more time to do whatever you were intending to do.

Paused by front panel, i tryed several times, sometime it works, sometime not....
I don't know what's the problem is, but target temperature for the nozzle = 0 looks strange....

Posting here because it seems it may be related to an earlier post.

I am trying printing with ABS for the first time so decided to upgrade to 3.0.12 but now have a really odd problem with Z offset. If I print a part (sliced in S3D) then I can dial in a Live Z offset of say -0.400 and get an OK print. However, when I print it again I now have to dial another -0.400 into the Z offset (so it is now at -0.800). It looks like the Z offset in firmware is perhaps getting cleared for some reason but the display is still showing the offset. What makes this odd is dialling in the extra 0.400 only has the expected effect and doesn't bury the hot end into the bed by moving the displayed -0.800.

In understanding this, it doesnt really help that the firmware (presumably) is stopping Pronterface setting a negative Z offset so I can really only use Z Live to approach this.

I am on the point of going back the .10 firmware since this has given me many hours of repeatable results, but I a keen to hear any thoughts

Thanks

Andy

This is probably something else, heat influences the PINDA probe. I am guessing when you're printing the second time the nozzle is right above the bed at its home position. waiting for the print job to start. The bed heated the pinda probe so you need to adjust the Z value.
Try moving the nozzle at z=70 after each print (I added this to my slicer to add), your live Z adjust should be the same for each print now.
