Ultimaker 3/3E?

[lime orchid]

Any hope of getting my UM3E working with Orca? I saw Prusa Slicer had an S3 profile, but I think they moved the toolhead changer to the other side when they updated to the S series. I guess that profile doesn't want to work with the 3/3E because of the hardware differences, and other issues, like g-code incompatibility. Also, the native g-code for Ultimaker is griffin, at least it is on my 3E, which I don't see as on option in Orca, so that may be a showstopper.

I tried the UM2 profile in Orca, but it didn't work, unfortunately. My GoogleFu found this on the Ultimaker forum:
"The Ultimaker 3 accepts G-code, similar to the Ultimaker Original and Ultimaker 2. However, backward compatibility has been broken, so it’s no longer possible to run Ultimaker Original or Ultimaker 2 G-code on the Ultimaker 3. If you’re using a different slicer than Cura 2, you’ll need to include a specific header in your G-code files for the Ultimaker 3. Keep in mind that while the Ultimaker 2+ Connect and S series also accept G-code, the files are converted to a .ufp format by default, which includes material information and metadata2. If you encounter any issues, make sure your G-code files are compatible with the Ultimaker 3"

Soooo... I guess I'm stuck with Cura? Which isn't horrible, but I'd rather use a single slicer for both of my printers in the shop, and Orca is just easier to use, IMHO.

My other printer is a BL X1E, which gets a lot more use, since it's significantly better in pretty much every way. But, I still print PETG and PA CF&GF parts on the UM3E. Because it's slow, it ends up making parts pretty strong, and the thing is actually very accurate, which is important for tool jigs and whatnot. It's been upgraded with hardened feeders/nozzle and magnetic bed, too, so it's still pretty useful.

I'm the one who wrote the Ultimaker S-line printer profile for PrusaSlicer. I did not include the UM3, because there isn't much information on the UM2+ connect and UM3 machines online. I think that the 3 and 2+ use the griffin gcode which is a slimmed down version of the normal Marlin gcode. The toolhead change is activated by just T command on the Ultimakers (as all printers should) and I would expect it to work similarly on the UM3. You'll need to confirm that the printer bed size is the similar to the UM3 though to avoid any collisions in the start Gcode.

The ultimakers also produce super sharp corners, I can tell you. I have access to a UM2+ connect and it blows away X1C in sharpness.

I'm the one who corrected the volumetric speed limits for the UM2/+ and I can confirm the UM2+ uses Griffin, but I cannot help further, only a colleague owns an UM3 but I can't get access to it, too little time for these experiments.

Thanks for the info, guys. I’m afraid my knowledge of gcode is limited, and what I do know is more for our CNC machine. There are a lot of similarities, but I’m hesitant to experiment and end up breaking something.
Parts for the UM3/3E are getting expensive, so I’ll probably retire it when it breaks down again.

The UM3 did indeed use Griffin, but to my knowledge it wasn't as locked down as when the S-series came out. IIRC it was as simple as copying and pasting the Griffin header into your start code. I went ahead and sliced a file using the default UM3Extended settings in Cura 5.9. Here is the resulting header produced:

Hopefully this helps get you on the right track!

Edit: I forgot Daid posted a bunch of helpful info around the time of the UM3's release: https://community.ultimaker.com/topic/15555-inside-the-ultimaker-3-day-1-gcode/

Personal project would be a gcode post processor

Used to like Cura. Now don’t

So does the the UM2 profile work for the UM3/UM3E? with flavor change to Griffin?
