<\/p>\nHelp me create a modular CNC\/3D Printing control system.<\/p>\n
The details:<\/p>\n
1) Stepper Controller Module
\nWill be based on the A4989 controller and be able to control up to 40v @ 15A
\nWill be easy to connect to main module via 5 pin header (2 Power, 3 Control)
\nMight also decide to have the Microstepping pins brought out.
\nExternal Power up to 40v via Terminal connections<\/p>\n
2) Main Module
\nThe main module will be the brain so to speak. Utilizing a ATMEGA2561 most likely. If not the ATMEGA1281. This will not only boost memory and speed over the original ATMEGA328 but also the pin count. Having a larger pin count will allow for more peripherals. Also the main module will include a nice small LCD and buttons for new features. Some of the features are… MANUAL\/SD CARD\/PC control switching. Setting the MicroStepping if i decide to break them out. And various other settings and information.<\/p>\n
5 axis ready
\nlimit switches ready
\nhoming switches ready
\nextruder\/rotary tool control
\nupgradable\/expandable<\/p>\n
OPEN SOFTWARE\/HARDWARE… schematics & source will be released.
\nmore to come!<\/p>\n
3) Misc Modules
\nThis would include things like… Serial to DB9 for older PCs, Control Modules for manual control of the motors. And other cool things to come.<\/p>\n
