Here is a video of my MMU, I already tested it in print, it works until the moment when the filaments intermingle ...
In addition, my printer is not calibrated at all, it is always in WIP.
So the video just shows the tools change, with the purge.

The base of the printer is a ratrig increased in size, with lots of little tricks.
The head support remains of the hack, because the addition of the servo at the last moment, will require a better integration. And especially to install the cutter at the lowest.

The MMU is a mix of lots of tricks, nottamentally transplanted on the MMU Zblairq, a big thank you! And also at Gravatron3000 for its sample codes.
This is not the final version, but everything is printed, it only remains to mount the 16 elements ...
I used dualdrive from bondtech, because I have a long tube about 1m, it must grow.
The scraper system, allows me to print continuously without using tricks, and especially to eliminate the limits of 6 extruders Simplify3D.

What do you think?

I can make the code and CAD files available if it interests someone.

For the fact, that the filaments intermingle together, I seem to have found a solution, but if you have ideas, examples, I am!

Edit: I forgot to thank DC42 for his help !!

I would urgently need it too.
I have two triggers at the filament loading level, I have windows of errors but at the end of the tool change.
M582 should be blocking and the windows modal, even during the tool change.
It's possible?

take a look to this thread

For my part, I use one at a time.
It smells good the fix

in the list of macros, File management> Macros, the right button "Run macro" does not work
Left click works

My config that works, for orion precision piezo:

M558 P5 I1 R0.4 F300 X0 Y0 Z0
G31 X0 Y0 Z-0.0 P10

M300 works at home, but not everywhere.
In homez.g, I put a beep to validate something, I have the sound.
On the other hand, if I create an M300 in a macro of the macro folder and the execution of the menu file / managment / macros, I have no sound.
But if I run it from the dashboard / macros menu I get some sound.

It's my panel7 that plays the sound

Sometimes you have to add G4 Pxxxx to block time

On one of my printer, the nozzle closes continuously, and checking this box, no more worries.
He has an M83, and S3D gives him an absolute gcode

Thank you DC42
I can still read ?651 375L, she came from duet3d.com

I have 2 others in 1651 375L, another bought directly at E3D which is not yet mounted, and the one that is mounted from also duet3d.com

The problem is that of E3d, I did not plan to install it immediately. There is another test to do?

check relative extruder, you never know

Thank you gavatron and DC42,

The problem with the T-1 is that if there is a filament loaded at the beginning of the print, it will unload it.
For now, I load my tool before,.

There is a method / trick for heating the hotend without selecting a tool?
No doubt the use of
G10 Rxx Sxx
T0
in the print file

M116 at the beginning of tpost # .g (which I already do)

@dc42

Did you report the issue on this forum? if so, please point me to the thread.

That's what I felt, not yet looked at what it was ...
