Tool changer print completed, UM3 print to start soon.
-
Well I already use Cura 2.3 and choose our "UM2 tool changer" profile in Cura that's all. However not sure about the firmware download. Newer Cura releases were quite restrictive there. To download our enhanced (Tinker-powered) firmware I use an old Cura release.
-
Like they say nowadays "it's in the making". Intend to print it on the UM2 tool changer and the UM3. But it's a long print, so be patient.

Daid starts talking about the forum again, I had to read this immediately I also have the font issue. It's a display resolution thing. On our retina imacs and macbooks the font looks nothing but great. But on "standard" displays ... :( Line thickness is simply too thin, so antialiasing doesn't work well there.

Just wanted to share. I've been printing PVA for more than 50 hrs now with the 0.4 mm nozzle without any issues. For PVA that's remarkable. 40 mm/s @ 0.15 mm layer, 190°C Don't know if it's due to the internal geometry or the comparatively low printing temperatures. -
@rasputin, do you have a step file? If not, something like this https://grabcad.com/library/housing-twin-cylinder-head-1 (might be a little overcomplicated
-
So just to see what the expectations are: Please suggestions for dual extrusion parts, which you think the UM3 will print well (or already did) and you'd like to print on your "old" UM2(+) as well.
-
Toolchanger print. Extruder 1 prints with the standard print head (like single extrusion), extruder 2 picks up the additional head.
-
This is usually where the fun - or frustration - starts, PVA on top of PLA. Really like the way Cura 2.3 generates the PVA support.
-
They don't wipe but cool down and heatup is quite fast and the timing is controlled by Cura. That means the new nozzle should reach extrusion temp exactly when it's going to be activated. I did most of the prints on the UM3 without a prime tower or ooze shield because I simply don't like that stuff. However for being on the safe side UM recommends a prime tower.
-
I've been comparing UM3 and UM2 tool changer for a short while now The UM3 offers a lot of stuff the UM2 never will (wifi, camera, bed leveling, huge linux brain, high temp print cores, ...). But if you focus on print quality it's a tight race. You can even use the same slicing settings in Cura. Just switch from UM3 to the tool changer profile and print it on the UM2.

@neotko, wow less than 1 sec, can you read my stuff before I actually post it
-
Hi guys, UM2 and 2+ owners, don't worry. I'm pretty sure Ultimaker won't leave you behind.
-
Hmm, I'm pretty sure they would have told me if they are going to use it.

It's been some time since my last post here Finally, Ultimaker announced a new printer which most likely will feature more than one extruder. So, just to fuel up the excitement some prints made with the UM2 tool changer add-on which ofc should be doable with the new Ultimaker as well. ... the tool changer project will be continued in a few weeks (btw, I don't work for Ultimaker product development)
-
That's what I did with the Rocktopus I posted in the UM3 release date topic. 0.8 mm black, 0.4 orange. But printing time for dual extrusion parts will often be dominated by the number of tool changes and the necessary time for reheating, priming or wiping.
-
Well, perhaps you could talk to them. And if you don't need an out-of-the-box solution but are willing to invest a few hours of work in your UM2 there are options.
-
Huh not sure, but I remember someone reporting that it's working.
-
Single extrusion will just work as usual. This dual approach doesn't require any modifications to be made to the standard single extrusion setup. That's really one of the most charming features. If you leave the 2nd printhead and its docking station in place you'll loose about 25 mm printing space in y direction. But it's a click on/off mount, so you can easily remove it and use the full printing area. You don't have to read this entire topic. There will be detailed explanations, a BOM and all required files available here in the near future. Mixing an old UM2 feeder and a 2+ feeder is not the easiest way but possible. As far as I know this requires gcode with relative e values and resetting steps per e with every tool change. Tinkergnome should know more about it.

Maybe, if you get the amount of silicone right after several trials. This idea is more an option for tinkerers who like to play around with silicone. But I like its simplicity.
-
That's a really cool idea!
