This Arduino Uno compatible controller is wired conforming the GRL v0.9+ standard. The controller can be used with the GRBL firmware and with EstlCAM. + +## Features + - The PC is fully electrically isolated from the CNC machine (optional). + - All inputs protected with clamping diodes and resistors. + - Probe inputs have a 100 Ohm / 100nF low pass filter to suppress spurious triggering. (Filter values may be experimented with.) + - 3.5mm Jack for spindle / laser / hot-end control + - 3.5mm Jack input for 2 probes. + - Serial interface fed out the back (TTL, not protected). For people in a hurry: CP2102 and isolator ICs can be left unpopulated. + - Standard 6 pin ISP programming connector fed out the back (not protected). + - Some juper block for IO-config + +Alvast een leuk plaatje: +![PCB Render](images/render2_composit_web.png) \ No newline at end of file
