Cubex Trio with Rumba and Marlin

Sat Aug 08, 2015 2:47 pm

Hello,
I hacked this Cubex (terrible software, expensive cartridges), and tranplanted a Rumba board + reprap display, with Marlin firmware.
Fans, lights, extra relays for the endstops, everything working nice.
I am almost done with configuring 1 extruder extruder 1, the left of the 3), purging, going over the cleaning lip before printing.

But to get my other extruders dialed in, especialy for the cleaning / changing extruders, i was hoping someone can help me ;-)


Anyone the same configuration?

Open for questions, and ready for answers ;-)

Awesome! If you could provide a few pics and maybe a quick instructional, I'm sure that would be really helpful to many who want to turn their expensive CubeX/CubePro 3D printers into actually useful printers!

At this point I would just run through the standard RepRap calibration process

as yours is basically a repstrap now : )

Congrats! I wouldn't even mess with the priming and cleaning lip--I don't do it anymore on my cube-pro. As more and more people go thru this process, it becomes a more compelling way to turn this expensive paperweight into a useful printer! Any photos or documentation you can post would be much appreciated!

Give me a couple of weeks, And i will document the transformation. At this moment i am still fine tuning ;-)
Once my first extruder is perfect, i will try the dual extruder wizard.

2 steps forward, 1 back ;-)

In the process of levelling the Z, i broke my first printhead. Want to change the 3 heads anyway, E3D is my favorite!!
I was almost ready printing 2 colors, used the profile Printrbod duo with HB, and tweaked it to get it succesfully working.
I am leaving on a holiday for the next 3 weeks, the project will have to wait..

But, as it prints now, 0.1mm layers, it is already beatifull, this printer rocks (solid)!!!

Update:
Printer is running fine now,

Electronics:
-Rumba Board with full graphic display.
-The 2 Y motors are wired parallel, on 1 stepper output, works fine, rest is default, 1 output, 1 motor.
-Extruder lights and fans are wired parallel, of fan 2 output, they switch on when 1 extruder is above 50 degrees.
-Parts cooling fan is wired on fan 1 output.
-Heatbed (220V) is connected true a solid state on the default heatbed output of the Rumba.

Nozzles:
-Designed adapters for the use of E3D V6 on the extruders. With a spring around the shaft, so calibration of the nozzleheight is easy.
-Tried a combo of E3D V6 and E3D V6 light version, did not work optimal, you can't use the speed advantage of the full V6 version, (software only allows 1 speed for all the extruders), so changed to an all E3D V6 full version, works much better.
-Have to add, i removed extruder 3, just to reduce weight, and probably will never use it.

Software:
There is no Cubex profile for a Rumba / Marlin combo, so i had to build one myself. Had a lot of things to tweak, but in the end, works, super with 1 nozzle (more is a problem, explenation on the bottom of this post)


Overall:
-Removed the waste box and its 2 mounts, because the nozzles are to low, and can collide.
-Mostly feed the filament directly in the extruder; the pipes running true the machine are not so easy to use ;-)
-To remove filament, i always push out 10mm, followed by a retraction of 100mm, works fine.


To Do:
-drill holes (4.2mm) in the bottom part of the extruder, so the filament guide of the E3D can go up to the extruder wheels, needed for reliable flexible filament prints.
-Look for a solution to use a longer cable so i can put the display in place of the Original (now the cables are 30cm, not longe enough, and longer cables give a lot of problems)
-Program + wire an output of the Rumba for auto switch off.

And i have 1 issue with 2 color prints, which i think is a S3D related problem.
The second nozzle is not retracted after the purge, so you get a mess on the first layer from a leaking second nozzle, while first nozzle is printing . Once past the first layer all is well, oozeshieId an primecube works ok. I am not alone with this issue, i found a possible workaround, but had no time to test it out.

It was a lot of work, but in the end, the printer frame makes it worth it.

Great work! Definitely making me consider throwing a different control board onto my CubePro...

The hardware of the CubePro family is really high quality so it's great to hear that you are able to get beyond the insanity parts of the design. I blog about the CubePro and have 3 that are essentially huge bricks right now. So, I am VERY interested in the details of your conversion for publication for other languishing CubeX/CubePro users.

Sorry, but i left the Cubix about a year ago;-)
Was a nice piece of hardware. But in the end, the 3 heads on the same Z height where to difficult to master.
Went to an ultimaker 2+ mk2 and now also an ultimaker 3. Gone are the days of tinkering.
