Is there an I/O pin on the xBuddy board for triggering an external camera?

I recently came across a blog post about filming time-lapses with Prusa 3D printers, written by Prusa Research.

The post describes how to write custom g-code to send trigger signals to a camera after every layer is finished. While it covers older models like the Prusa MK3, I couldn't find information related to the Prusa MK4.

Specifically, for the Prusa MK3, one should send trigger signals through pin 73, and pin 20 for the older machines.As far as I know, the MK4's xBuddy boards do not have Raspberry Pi pin headers. This leaves me wondering about my options for the MK4.

I'm faced with the following questions:

  1. Do xBuddy boards have any other undocumented I/O pins that can be utilized for this specific case?
  2. Or should I resort to using Prusa Connect for time-lapses?

I am eager to hear from fellow Prusa users who may have experience with this. Thank you!

They do have some extra undocumented pins. The problem is they are undocumented, so nobody knows what they are.

I asked Prusa and they wouldn’t tell me, but said they would released schematics of the board. Unknown when that will be though.

Considering Prusa research's recent moves regarding to open sources, I also think that they will not release schematics anytime soon.

I will try Prusa connect instead.

Thank you for sharing your experience.
