This project has been forever on my to-do list, and this weekend I finally had the opportunity to start on my "dual controller" Shapeoko3 XXL. I really like the Carbide tool chain and workflow, and I also really like the Estlcam CNC Controller and it's cool collection of controls. Hence I've decided to combine the 2 controllers into a single box, allowing me the on demand choice of either of these great controls. I've decided to leave the homing switches on the GRBL controller and run the ESTL CNC controller without.
My next step is to layout, implement, and integrate the controller board selector controls, so for now I'm simply connecting one board or the other (GRBL or ESTL controller) as the project demands. In addition, I'll be adding a collection of extended manual operators that both GRBL and ESTL support.
