The M.A.R.S. Kit
Set up your fixture one time and stop chasing your zero.
Zero it once.Every cut lands in the same spot.
Modular fixture system for repeatable desktop CNC setups — precision hardware with electrical isolation, multi-phase workflows, and HeliosForged integration.
Software & materials require a free account. See terms for restricted-state ordering.
Join the next batch
M.A.R.S. kits are made in batches. Join the waitlist and we'll email you when the next batch opens. Current lead time is 4–8 weeks; longer if parts or equipment are delayed.
How M.A.R.S. works 
-
Mount it.
Bolt the fixture base to your mill's table and lock your part in place. The base stays put between jobs, so you only do this once.
-
Probe it.
Find your zero off the fixture one time. After that, every setup starts from the same known point.
-
Run it.
Run your program, flip or swap the part, and keep going. Every side lines up without re-indicating.
