@Morlau Hi I am considering a Troodon. You have used one can you offer any insight? How fast is it? What are the shortfalls?

Good day kitedemon,
Troodon is a good printer but 3d printing experience is mandatory. Unfortunatly, there is not much information from Formbot regarding printing operation and trouble shooting issues. As an exemple, I am still loocking to understand some of the color code on display after 6 months. Levelling process is easy, when changing extruder assembly, and must be followed step by step. Printing speed is related to filament type. Wifi work perfectly. You can visit Formbot web site and download documentation and you will see what I am taking about.
Other than that, I am still very satisfied of printing quality, printing with many types of filament (PLA, PETG, ASA, Wood, Nylon).

Hope that help !

I looked over the manual, the menus look ov early complex. Thank you for your insights! I have been considering a Voron kit or Troodon. Thank You!

Hello Morlau, I just bought a troodon 400 and and am looking for some help in getting my first print down. the first mother and child figure printed perfect from the user sd card, but I haven’t been able to have any success yet from my own stl files off cura.

Good day JamesQ,

Can you give more information (pictures) concerning your failed print ?

Unfortunatly, I do not use Cura, I slice with Simplify 3D that work pretty good with my Troodon

You can learn Cura in details and others from

There are excellent video courses regarding every steps of 3d printing with different slicer.

Let me know about it…


Hi Morlau,

I have been using my troodon for quite a few months and have had really great results. I decided to upgrade my hotted to a copperhead which has also been good. That being said, I have not made any changes to the printer configuration. ie max temp, etc. Any help with changes I should make would be helpful. I did a PID Tune and got a warning about temperatures possibly reaching 470 if heating tube left on.

I’m also experiencing a z seam gap which wasn’t an issue with the V6 hotend.

Any advice or resources would be helpful.



Hello Albear, there are upgrade that I did on my Troodon :

  • Installed a DDE ( Direct Drive Extruder)
  • Always use Steel extruder .4 or .6 mm
  • Installed corner angle brackets to reenforce the frame resulting reducing vibration

Also, I used Simplify 3D as a slicer

Take note that PTFE tubing start to melt around 270*c

Hope that help !


Hi @albear welcome to the forum

For some reason that error message comes up on the Troodon after you run the pid tune, Its listed as an error but I think its more of an FYI

I have done some work with Formbot on there firmware. If you notice the Troodon firmware is no longer available for download. they have withdrawn it with a new release coming shortly.

I believe the FYI message will be addressed.

I have seen a lot of these machines and I do have to say they are pretty rock solid.

Thank for the reply!

I’ve had some really great prints over the last few months. The upgrade to the copperhead was a bit of an adjustment. Had to lower value in linear advance.

I was looking at where they’ve posted RRF 3.0. Was contemplating upgrading but sounds like I should wait for Formbot to post.

Thanks again for the reply.


Hey @albear

RFR 3.0 is not quite there yet, have to be careful with the upgrade as well it’s not standard Duet gear under the hood, it’s a custom board and screen with, unique connector cable. In the config files, there are a couple of differences in there that I am not sure would convert to RFR3

I agree, let formbot do the upgrade and verify the config.g before you install it.
