Warco Major CNC build log

[Robin Hewitt]

I do like making things difficult for myself, but when it comes to the firmware I become a control freak. If it doesn't do what I want it to do then I want to reprogram it down the USB rather than fudge it. Nothing quite so reassuring as having all the source code :whistling:

Stepper drivers, phase controller and pendant connect with RJ45 patch cords to keep everything neat and tidy, lots of buttons and well buffered I/O for everything I could think of.

The limit switch and tool touch inputs are designed so I can short them to ground via an LED and get a visual check at the far end of the wire. Three FET's to drive the suds pump, quill lock and something I haven't thought of yet. A socket for one of Gary's jog encoder do-berries, a main motor kill switch to keep me safe while setting up, fuses on board and an input to tell me if 12V goes away. If the 5 volt fuse goes then it's goodnight Vienna so no way to monitor that.
