I love the way simplify 3D works. Im not an expert but even so it seems soooo easy compared to my home built cnc router built on tinyG controller (modified GEBL I think). TinyG is a great controller but not many options to control it. Chillipepr is about your only option and you have to be online to use that which is annoying. OpenBuilds got started with some nice control but alas it supports nearly everything except TinyG. Obviously they want to sell their own hardware.
I have checked out so much software and Simplify3D is the Best out there. Just wish we had it for other cnc operations.
