After a lot of reverse engineering, testing, and late nights, I’ve finally completed the first working retrofit control board for older Epilog laser machines that keeps ALL original mechanics intact.
The main goal from day one was:
- No hacking up the factory harness
- No destroying a perfectly good machine
- No replacing motors, rails, optics, or mechanics
- Keep the original high-quality Epilog hardware
The retrofit board plugs directly into the original Epilog harness using the factory connectors. No cutting or modifying the machine wiring loom is required.
Even the factory rear panel connectors line up correctly with the retrofit setup to keep everything looking as factory as possible.
The system interfaces the original Epilog mechanics with a Ruida controller using custom modified servo drives running custom firmware specifically developed for the Epilog platform.
The board also includes provisions for an onboard Raspberry Pi for things like LightBurn Bridge, remote access, monitoring, future integrations, etc.
Current status:
- Original mechanics fully retained
- Factory harness plug-and-play
- Rear factory connectors line up correctly
- Ruida integration working
- Motion control operational
- Custom firmware running on modified drives
- Raspberry Pi integration provisions onboard
- Minimal additional wiring required (mainly drives + Ruida connections)
The idea behind this project was to save older Epilog machines from becoming scrap due to failed or obsolete controller boards, while still keeping the incredible mechanical quality these machines were built with.
A lot of retrofits out there require gutting the entire machine. This does not.
Still refining things and doing long-term testing, but the first board is alive and working.
Boards, pricing, installation information, and links should be available shortly. I’ll continue posting updates, testing results, and progress as development continues.

Bad video, I know — I’ll get some proper photos and a better demo video up within the next 24 hours.
Would love to hear from other Epilog owners interested in retrofits, repairs, or keeping these machines going long-term.
