First complete job … completed
I finished a little Air-app to stream complete jobs to the Grbl and render the result. This is the first “full scale test” running some 7000 lines of sample G-code I scrounged from this thread on CncForum. The Air-app feeds g-code to the microcontroller one line at a time, while the microcontroller generates the steps and feeds them back to be simulated in the Air-app. Everything seems...
A matter slicer for any CNC
Discovered the Cricut via Ladyada the other day. She points to this instructable where Instructables user opendous makes solder masks using the “lowly” scrapbooking machine. I don’t need yet another machine sitting around the house, but I see that Cricut sells affortable blades and blade housing ready for CNC action. I’m ordering a Cricut Deep Cut Blade Housing to add foil...
Last major feature in place: Helical motion
After completing the support for helical motion, the project has reached the point where it is theoretically feature complete. It supports all common g-code that I have seen in the wild. It does lines, arcs, helical motion correctly at the designated feed rate. Grbl now uses a simple buffer mechanism to decouple the production of stepper pulses from the computations of steps. A couple of very...
