Build Log

Date	Activities
2015-04-24	Screwed down the main table
2015-04-26	Rebuild Y axis motor plate in OpenSCAD, and lasercut it.
2015-04-30	Printed new guides for the Y axis belt [1] -> A little to big. Screwed new Y axis motor plate into place. Belt a little too loose. Need to place pulleys a little higher.
2015-05-03	Printed parts to hold 2 endstops on the Y axis. Endstops are in place now, but not yet connected.
2015-06-14	Connected endstops to Arduino controller Updated grbl on Arduino to 0.8c (custom compiled, to accommodate for different pin configurations, and homing only on X and Y [2]) Testdrives Problems: Noise on the endstops, triggered e.g. when starting the spindle -> maybe bigger pullups? Right X endstop cannot be triggered, due to size of the z-axis sled

Executing on the machine:
- Universal G-Code Sender - Java, requires rxtx library, on OS X follow [3] to install
- grblgui not tested

- RegRap includes information on what commands are supported by grbl. Also has shorter Cheat Sheet
