RE: GIPO - Canon EOS R8 - 2.5mm
Hi, I went through your videos again and noticed that the holder I’m using doesn’t provide a good connection between the cable and the board (2.5mm jack) 🙂
Link to the model: https://www.printables.com/model/1016997-prusa-gpio-hackerboard-cover/files
I’ll be redesigning it! 🙂
RE: GIPO - Canon EOS R8 - 2.5mm
Check the file MK4_GPIO_Cover_R2.stl which I am talking about in the video 🫡
RE: GIPO - Canon EOS R8 - 2.5mm
Btw... The correct position is G1 X241 Y170 F10000
I made a mistake in the video. 🫣
With some cameras I had to trigger the focus first so maybe try this G-Code instead:
;Time-lapse - start M262 P0 B0 ;Pin 0 as output M262 P1 B0 ;Pin 1 as output G1 X241 Y170 F10000 ;Park on possition G4 P500 ;Wait 500ms M264 P1 B1 ;Trigger focus M264 P0 B1 ;Trigger shutter G4 P300 ;Wait 300ms M264 P0 B0 ;Release shutter M264 P1 B0 ;Release focus G4 P500 ;Wait 500ms ;Time-lapse - end
RE: GIPO - Canon EOS R8 - 2.5mm
Thank you so much! I’m using manual focus instead, so I removed the focus-related parts of the code 🙂
;Time-lapse - start M262 P0 B0 ;Pin 0 as output M262 P1 B0 ;Pin 1 as output G1 X241 Y170 F10000 ;Park on possition G4 P500 ;Wait 500ms M264 P0 B1 ;Trigger shutter G4 P300 ;Wait 300ms M264 P0 B0 ;Release shutter G4 P500 ;Wait 500ms ;Time-lapse - end
RE: GIPO - Canon EOS R8 - 2.5mm
I am using the manual focus too, but I still had to trigger the focus pin. 🫡
The cable trigger works like the real button the camera.
There is also "half triggered position" which serves as focus position. 👍
RE: GIPO - Canon EOS R8 - 2.5mm
It still won’t take any pictures for some strange reason.
See the attached images—I'm using the same code you provided, with focus enabled.

RE: GIPO - Canon EOS R8 - 2.5mm
If you have any ideas, please let me know! 🙂
RE: GIPO - Canon EOS R8 - 2.5mm
Does the camera reacts when you try these steps?
RE: GIPO - Canon EOS R8 - 2.5mm
Hi!
I solved the issue by testing with a different 3.5mm to 2.5mm adapter, and it worked! It seems the original adapter was faulty. The camera now responds to the shutter command you provided.
Everything is working perfectly now, and I just want to thank you again for your dedication and detailed responses—they truly make a difference!
RE: GIPO - Canon EOS R8 - 2.5mm
It's nice to hear that it worked out in the end 👏
I'm looking forward to some nice time lapse videos.
RE: GIPO - Canon EOS R8 - 2.5mm
Hi!
Here you can check out some of my timelapse videos! Most of them will be Prusa-only—I missed open source, so I sold my X1C 🙂

A huge thanks again for your help! The timelapse videos are 100x better now!
RE: GIPO - Canon EOS R8 - 2.5mm
They look amazing! 😉
Good job ☺️
RE: GIPO - Canon EOS R8 - 2.5mm
Thanks! I'm trying to develop a workflow that makes it easy to create nice timelapse functions and allows for writing a checklist of what needs to be done, etc.
I'm working on a local .html file with checklists for everything that needs to be included. I can share it later if you're interested—I’ll probably upload it here 🙂
I'm also working on a profile where I've tweaked various settings to achieve better results (in my opinion), and I can share that as well.
Thank you again!
RE: GIPO - Canon EOS R8 - 2.5mm
I created a checklist helper; it's still in the early stages but already has some cool features like auto-generating G-code and prompting questions to verify completed tasks. Let me know if you have any questions!
RE: GIPO - Canon EOS R8 - 2.5mm
That look amazing!
Could you post it on github as a gist afterwards so that we can make it a public tool using https://gistpreview.github.io/ ?
I would make a video on it and recommend it to everyone 😉
RE: GIPO - Canon EOS R8 - 2.5mm
Thank you, if you see anything that needs to get added or changed let me know!

RE:
Hey again!
I've tested various profiles and settings and found what works best for me. Occasionally, but very rarely, I experienced a layer shift in the Y-axis and noticed that the circular purge tower didn’t always stick properly. After making some adjustments, everything has been running perfectly!
I’ve saved the settings as a .3mf file for others to check out.
Big thanks for your first video—this wouldn’t have been possible without your help!
