[Cerrado] Successful MMU2 prints  

Re: Successful MMU2 prints

I like them, like them alot

Re: Successful MMU2 prints

almost 28 hours, no jams or skips. 3 colors PLA Hatchbox brand, 1 perimeter 2% infill(rect)

fun facts the STL weights 78grams and the wipe tower 118grams.

normal one color run time is like 12-15 hours.

the print came out stringy so in the new configuration of the MMU and new extruder cooling system looks like i'm going to drop to 200c from 205C on everything for the next stage.

original STL needed significant modification to be multi-material ready

Re: Successful MMU2 prints

one piece at a time. apparently i'm still hot in this configuration at 200, so maybe 195-197 on the next go.

no issues just fire and forget to the MMU2. didn't touch it at all the last 48 hours. this was a 5 color print. Silver, blue, red, orange and white

little pillowing telling me the temp is still a little hot.

hand painted next to color printed

Re: Successful MMU2 prints

Simply awesome. Functional MMU2 print for RC.... LOVE IT.

Re: Successful MMU2 prints

problem is the mesh for the front piece is heavily damaged. i emailed the original author to see about a STEP file or something that can get around the damage. the STL works in the slicer but it is extremely difficult in trying to separate the boundaries for the colors. if i have to try and fix the front piece it is going to take me possibly weeks with the constant software crashes.

Re: Successful MMU2 prints

far as i got today

rear window 2 colors

KC lights and rollbar 4 colors

Re: Successful MMU2 prints

what a nightmare this mesh is very damaged.

so begins about 15 hours of crossing my fingers and hoping.

Re: Successful MMU2 prints

doesn't it want to make you just paint the damned thing?

Re: Successful MMU2 prints

i painted like 10 of these hee hee i want my printer to do it LOL

death or glory

this run is at 197C

how dare u....... this is mmu2 forum. 🙂

Re: Successful MMU2 prints

done, yeah not perfect but did the job. some issues either with the slicer or possibly the mesh i need to look at the slicer in some areas a little closer. however no skips, or missed layers and zero intervention by me on either of the long print runs. i just sent the program setup the machine and walked away.

at 197 i didn't get strings on the model but i honestly can see a difference in the surface between 200-205 and 197 and i would prefer the 200-205 range with the strings.

everything is one perimeter for lightness but it will show any mistakes or burn through.

Re: Successful MMU2 prints

I am much happier now; seems that I have resolved the problems I was having with the printer:

https://www.thingiverse.com/thing:1519257

4 filament makes (all PLA):

Prusament Pink (which is absolutely gorgeous and really shiny)
Fillamentum Purple Red
Plasty Mladec Black (via PR)
Plastika Trcek White (local filament manufacturer)

27.5 hours at 50% (120 mm tall)

Since I made the changes to the printer hardware, I have only had one fail due to a filament break in the Bowden.

How did you "assemble" the parts before slicing?
Did you do it in KISS or a seperate software ?

I tried it in Slic3r and failed

Re: Cheshire Cat.

Just started a 5C print at 80% (200 mm, with the correct yellow eyes).

This is a model I have had since MMU1 beta-testing. The original designer (linked in my post) prepared a special model for us to test. Unfortunately, that model contained an amount of damage (mainly inside-out triangles) which I managed to put right (not fix). At the time, we were asked to keep the model to ourselves and not distribute the STLs.

I had several attempts to get this printed with MMU2; this was the best one, and with the Prusament Pink, it really does look exceedingly good 🙂

I now have a pre-release alpha KISS version which allows >4 extruders, but 32-bit only, so I had to hugely reduce over-sampling to get it to slice.

The model only has 4 STL files, but with KISS, it's easy to assign individual meshes to extruders, so the two eyes are now assigned to E5 (yellow) and my fingers are well and truly crossed 😉

Re: Successful MMU2 prints

Hi there, just a post here to say many thanks to all you the menbers that help people, I read a lot during the 4 past day, because I was depreciate about the MMU and all the problem I have, now it's work as I expect (for two color ...) and it's not a big print but it's the first, and I want ta say many thanks to newguy , PJR , wayne.s4 , khalil.n , daniel.a6 (and all other) for all the helpfull you have been .
And this is my custom thing > https://www.thingiverse.com/thing:3242979

3H print (MK 2.5 ; 0.2 layer ; both Dailyfill PLA), first final print! ^^

Print Lizard tonight, see him tomorrow ...or no!

Re: Successful MMU2 prints

nice color choices. black and gold almost always look cool

Re: Successful MMU2 prints

Here's the big one 😀

200mm tall, 5 colours, 64 hours 22 minutes.

Prusament: Ms Pink, Galaxy Black
Fillamentum: Red Purple, Fluorescent Yellow
Plastika Trcek: White

Same model as before

Re: Successful MMU2 prints

Most impressive Peter. 2 day plus, 5 colors. Has to be other a 1000 filament changes?

I thought kisslicer only did 4 colors?
