Gestalt Data is very limited and no obvious previous work has been done
I have been digging since almost four hours for details about making CNC plotters there is hundred of tutorials but all using grbl with Arduino uno, I almost found nothing about Gestalt even in the Fab archive, the MTM website also gives no details, the repo of Gestalt have example codes and design files but no clear instructions that I could understand:( Those people http://archive.fabacademy.org/archives/2016/fablabtrivandrum/machine_building/team_1/index.html made a plotter but they used Arduino mega and ramps, is this a pass !!! I don't think. This instructable: http://electricdiylab.com/diy-mini-cnc-plotter-machine/ uses an arduino code with stepper and servo library along with a code in processing software that imports Gcode and interpret it to arduino uno, I don't know if we can use this with software servo and software stepper libraries on Attiny I will still try to explore more. just wanted to share so you can Add on
