Ultimaker Mark2 - The Smart Dual-Extrusion Upgrade

Yes it works but you need to change the text in the .cfg files that you put in the variant folder.

 

This is for the 0.4mm nozzle:

[general]
name = 0.4 mm
version = 4
definition = Mark2_for_Ultimaker2
[metadata]
setting_version = 6
type = variant
hardware_type = nozzle
[values]
machine_nozzle_size = 0.4
machine_nozzle_tip_outer_diameter = 1.05
speed_wall = =round(speed_print / 1.25, 1)
speed_wall_0 = =max(speed_wall - 10, 1)
speed_topbottom = =round(speed_print / 2.25, 1)


and you can find the other details you need to copy from the Ultimaker 2+ files in the same folder for the relevant size nozzles. No need to reset, just close, change and relaunch.

I got the nozzle switching happening smooth now using Mark2 Firmware.   I just had to edit the nozzle offset to 18mm  and set the docking position to X=225.8  Y=180.4     nice and smooth now.

next step is editing the Mark2 files / profiles to work in Cura 4

 

UM3 conversion :-)

Looks great - any plans to sell upgrade kits? 🙂

"setting_version" for the variants is now 7

I think, that's all -  "cura.log" gives you more hints, if it doesn't work.

Thanks Tinker !   no plans to sell any kits,  it's not very practical I guess.

The only thing I needed was 2   sets of the 2+ extruders   which I had from doing the originall Mark2 conversion. and 1 UM3 head with the cores.

 

I just printed the 3D model from the Git hub for the Nozzle shift lever bracket.   used the location from the UM3 cad model  to drill my UM2 side wall for the bracket.

 

I totally gutted the UM3 head lol.  I removed all of the IC's and the resistors,  then I manually jumper wires form the core contacts up to the main cable header.

and of course the Z- sensor is non operational.   ( super easy to level the plate anyway)

 

At the end of the day what I ended up with is a :

UM2+ Mark2   with quick change CORES   🙂

Great work!

Just for interest (and as I plan to do something similar on my UMO) - where have you changed the docking position - in Cura or Marlin?

Currently I have also issues to understand, how the z-switch/hight modification is done, but I guess thats another story...

Any hints appreciated... 🙂

The Mark2 Firmware handles all of that.  I adjusted the docking position from the Ultimaker OLED display,  that menu allows you to set the X & Y position   to move to.   It turns out that the same motion to dock and un-dock the magnetic 2nd head also works great for flipping the lever on the head to lower or raise the 2nd CORE

Sorry if this is not the correct place. I have got to the wiring stage and am having some issues. Could someone help or are there some images of the mark 2 board installed I could look at? Thanks. I have checked again and it seems that the wiring pictures do not load for the bottom half of the wiring steps. Is this the same for all?

I documentation recommends HTPLA (GreenTec/PlaTec) but I have no idea what that stuff is or where to get it.

 

Has anyone else used ABS?

 

I am printing out the Mk2 parts in ABS (fully enclosed) one at a time, as I know there is some shrinkage, and wonder if it might cause the magnetic functionality and or fit to fail.

 

Alternatively, maybe PETG is better? I do have some MakerGeek Raptor HTPLA but read that HTPLA warps during the annealing process?

 

Advice and material successes? Prefer to use something more durable than plain PLA.

 

Cheers

I would stay away from GreenTec/PlaTec for mechanical parts that are subject to force in any way (based on my own experience). It has very good resistance to heat, but that material gives in (softens) after a while. How long depends on the amount of force it is subjected to.

The Mark2 instructions has the feeder located on a bracket near the back upper left corner.

 

Why is that?

 

Can the feeder and stepper simply be installed lower, mid back left using the existing holes (or drilling ones if not present)  and opposite the first feeder on the mid-right side? I use a top enclosure and it would seem that the feeder/wires/bowden tube would end up arching much higher up above the top frame so might not work well with enclosures?

Upper left was chosen to reuse the holes there, as UM2+ does not have the 2nd feeder mounting holes. You can mount it at the same height as the 1st feeder on the opposite site if you want, there is no reason against that.
