From what I can tell, the stock firmware for the Troodon isn't even available for download anywhere. The firmware for their other machines is provided via zip files hosted on a variety of file hosts (some on drop box, some on google drive, etc).
Also, Vivedino/Formbot appears to be a very small company. It looks like their entire lineup aside from the Troodon uses the same marlin motherboard.
All of this combined makes me think that perhaps a 3rd party designs boards for them. If that's the case then they may not even have someone who could provide help with firmware.
