Hello @ndng28, welcome!
@Autonomous created Bosch 1617EVS tool mount for low rider 3 and seems to be getting great results on their LowRider 3 (LR3).
Regrettably, I didn’t see autonomous’s LR3 build until after finishing mostly-assembled my own LR3 project with the Makita recommended by the docs. I happen to have a hefty Bosch 1617EVS too, and just assumed it was too heavy, maybe it still is for the MPCNC Primo? Hope that helps, cheers!
