last commit for mmu2_v2 firmware - Jul24??

Asking jakub.d or PJR

Is the mmu2 firmware still a separate branch of Prusa firmware or did it get merged into the mk2.5/mk3 branch?
Asking because the last commit i see for mmu2_v2 branch was on July 24:
https://github.com/prusa3d/Prusa-Firmware/commits/mmu_v2

Just trying to stay on top of firmware mk3/mmu2 commits and pull request.

Re: last commit for mmu2_v2 firmware - Jul24??

MMU firmware is MM-Control-01: https://github.com/prusa3d/MM-control-01

Some changes today, but not the one I has hoping for - I think that each MMU pulley can now be calibrated.

I've been following the mmu2 firmware github -
Some updates to the firmware have been posted, along with instructions on how to build the firmware in Arduino IDE. Since this not a full release, a prebuilt firmware is not included - you'll have to roll your own firmware. Have a print running, so I'll try it later.

Some but not all improvements, check commits for full list:
README.md
add_pulley_correction
Store separate bowden length for each filament
Return to first extruder after bowden length calibration

Has anyone had success building the FW and flashing it. I tried as per the instructions for the updates mentions on the previous post and couldn't get Slic3r to load the hex.

Upload directly from Arduino UI.

can someone post a hex file? I have yet to get a successful print and want to try an updated firmware to see if that helps. Thanks.

I'm at work now. But the instructions to compile the MMU2 firmware in Arduino IDE are actually pretty good. Arduino will upload directly to mmu2 without needing a .hex file.

https://github.com/prusa3d/MM-control-01

If your looking for a .hex file so that slic3r can upload to mmu2 instructions are a bit more complicated..... So I'd go the easy route and use Arduino.

Please wait with the update! We are still polishing the code, it will be out soon 😉

You can compile the firmware, but I suggest to wait for the official .hex file.

MK3 firmware 3.4.1 Final

MMU2 firmware, lastest commit as of day 10/9/18 > flashed with Arduino 1.8.6

----------------

Quick instructions for new Ardunio IDE user (windows):
Install Arduino IDE (prusa recommends version 1.8.5)
https://www.arduino.cc/en/Main/OldSoftwareReleases#previous

Unzip the firmware file from github
https://github.com/prusa3d/MM-control-01

Goto unzip folder
Double click MM-control-01.ino
Arduino will error once you click on MM-control-01.ino
It will ask you to make a folder named "MM-control-01"
Let it.
Close Ardiuno IDE.
Then move all contents of zip into the "MM-control-01" folder that was created.
Goto "MM-control-01" folder
Double click MM-control-01.ino
Follow Read.me directions on how to add the Original Prusa i3 MK3 Multi Material 2.0 board
Only thing the read.me doesn't mention is you'll need to also add tmc2130 library
Compile firmware
Connect mmu2 with mini usb cable to computer
Make sure correct com port is chosen in Arduino IDE
Click upload

---------------

I updated the mmu2 firmware 1st.

Interestingly when I looked at the mk3's lcd screen in the support tab - firmware 3.4.0 displayed mmu2 firmware version as old version.
When I updated the mk3's firmware to 3.4.1, the support tab showed mmu2 firmware version 1.0.1-117
(So i'd say you should also update mk3's firmware)

This was a just brief howto......please wait for official firmware as per jakub.d

I can confirm in new firmware you can calibrate all pulleys/hobbed gears independently. And keep calibrating its length like b4, just had to figure out how. (dont worry its intuitive)

Also it seems to exit service menu itself once done calibrating pulleys, unlike old mmu2 firmware. <Wrong, need to figure out how to save lengths. I'm sure when it's officially released, they'll explain the method.

I have not confirmed the new feature to detect filament in selector during a reset.

I have not printed yet..... will update.

Ok, I'll hold off for the official release. Where is the best place to check? Here: https://www.prusa3d.com/drivers/ ?

Re: last commit for mmu2_v2 firmware - Jul24??

Only pulley calibration is new? Nothing else?
My diameters are nearly the same and this is not the root cause of my not working Mmu. I have it since a month and the only development which was done in that time was the gear calibration? Very disappointing that I still cannot use this new product because of several load / unload issues, missing layers etc.

How can we get a running mmu without tweaking several settings as I use just prusa filament and checked my mmu mechanically several times now (did some changes without any significant improvement) and I am quite sure that it is as it is supposed to be.

https://github.com/prusa3d/MM-control-01/releases/tag/v1.0.1

Released today

Just flashed it. Hopefully this fixes my issues even though my pulley's aren't that different.

Here is a link to a new thread to discuss the new firmware: https://shop.prusa3d.com/forum/general-discussion-announcements-and-releases-f53/mmu-firmware-1-0-1-is-available-t25136.html

Re: last commit for mmu2_v2 firmware - Jul24??

Little disappointed at the overall lack of documentation on this release. No idea how to do the individual calibration or flashing without Arduino. Also in the 2 months since release this is the only improvement we are getting? I have wasted so much filament trying to get settings right that have no documentation like ramming.

see my post above. it should help get you started.

I plugged in the micro usb to the MMU unit and flashed through slic3r.

I'm at work, didn't flash today's release. This is based on my experience from version 117. This quick unofficial guide assumes your are familiar old procedure.

I didn't even check to see if there was a menu option for bowden length calibration.

Do everything as b4. To get into service menu.
Hit reset button, hold middle button until homing sequence finished and 1st and 5th light on. Then hold left button until selector moves to position 1.

Calibrate as b4. The way to repeat confirm/repeat calibration is after the filament retracts back into mmu and the light turns green - Simply hold and release middle button and calibration will take place again as b4.

Once you are satisfied the filament is coming to the position you are satisfied with. Press middle button too have filament retract back into mmu2. Once light turns green you can press and hold left button to move to next filament. Follow same procedure for all filaments.

What I'm not sure about was how to save the lengths and exit. I'll flash new version tonight and update here. I'm sure official instructions will be posted soon.
