SRT Gearbox : August Update and news
🕑 Added 2025-08-23 06:13:47 +0000 UTCThis month, it’s a minor update, which doesn’t really reflect the mountain of work completed over the summer.
The update boils down to:
No Turn fix: the upper bearing lip (highlighted in blue on the image) had been missing since the last update. If your gearbox is already printed, you can replace this lip with an M5 washer.
Seq holder RHD: a small piece of plastic was sticking out.
Body2 get rid of a feature that was canceled below the carriage
Major cleanup work on my side to remove duplicate functions, fix errors, and completely reorganize the source files in order to… archive this project.
Yes, indeed, we’re reaching the end of the road for the V10. The 3D part is finalized. There are still a few improvements to make on the firmware, but the project has finally reached maturity. That doesn’t really show in this update, but cleaning up all the files takes a huge amount of time—and it’s a necessity for the future.
I can already hear some saying that the end of V10 means the beginning of V11. Not really. There are too many ongoing projects right now to start developing a V11, and I don’t yet have enough ideas to justify one. Well… I might have a lead… but that’s something we’ll have to discuss together.
Meanwhile, I’ve mainly made progress on two projects:
Competition Control Box: added support for the 6th actuator, and a complete code overhaul to allow configuring the control box directly through the Arduino IDE serial monitor. Basically, we’ll be able to communicate with the box just like with the driver:
Send P to display the parameters menu (set max travel, margins, connected motors)
Send F to display the functions menu (calibrate, test, etc.)
Send D to display all saved parameters
It might sound a bit abstract, but the code is structured so that at every step, the user is guided with clear instructions on what each command does.
GT Tensioner: I’m continuing the first driver tests. At first glance, the P1 will still remain more refined (more responsive/accurate/silent). I hope the GT V4 will be ready by December.
As usual, the 3D files are available here for PRO contributors:

RHD mod Body2 still has the unused feature cut out. I didn't see the model for the lid. Also , the print orientation of the sequential holder (RHD) doesn't match the body. So the cover looks odd against the texture of the body. Both of these issue are minor, but i thought i would mention it incase it was an oversight. I've really enjoyed the SRT V10 journey. Keep up the good work!
