Original + with dual extrusion

Original + with dual extrusion

Hello, I added a second extruder from the Original update kit. Therefore to use Cura I have to set it up as an an Original with the heated bed, and change the position of the end stops on my printer Original + to the Original position specs? At the end instead of at the start? Or can I do a custom setup to tweak Cura so I don't have to change anything on my printer?

Thx

What upgrade kit do you mean? The dual extrusion upgrade kit for the Ultimaker Original? Don't use that one on an UMO+! The temperature sensor is different (thermocouple vs. pt100 on an UMO+) and if you use that heater cartridge which is made for 12V iirc with 24V you will heat with four times the power, i.e. with 160W (good way to burn down your house).

Actually the heater is 19V (umo) on umo+ it works but gives a weird PID. And ofc everything else is on the spot. Also you cannot use 2 different PIDs on old-zero-updated umo/umo+ firmwares. So.. Long story short, think about moving to a mark 2 with um2 hotends and probably a small china clone um2 screen to use tinkergnome firmware directly (but ofc china clones are bad quality, but the real deal is 80€ for a um2 oled screen)

I have 2 of the same UMO+ temp sensors. They seemed to work fine in Cura's UMO setup test.

No one even answered my question...

So, therefore to use Cura. I have to set it up as an an UMO with 2 hot-ends and the heated bed, and change the position of the end stops on my printer UMO+ to the UMO position specs, at the end of the build volume space instead of at the start?

Yes. Check the extruder 2 offset so it match yours and that will be the data you will need to edit to calibrate the printer on Machine Settings.

Endstops, that's something that don't matter on Cura, that's handled by the machine unless you have install some modifications.

Also, OFC you don't need to do the silly printer check it does when you install a new profile.

Thanks.

But for calibrating, zeroing print bed, the end stop is in the wrong spot is in the place for the preset UMO profile and there is no option to add a second hot-end to the preset UMO+ profile. Have to create a custom profile? Or zero with the UMO+ profile then skip all that when I set it up with the UMO profile?

Cheers

Indeed skip all that auto test stuff.

Why would you need to zero with one profile? The start sequence is what will run the home sequence etc.

Indeed you could add a second extruder editing the json file of the umo+ but that’s something I never done, I use s3d.
