I need help interfacing my windows XP machine with th grbl shield and an UNOr3 with a grbl Chip. I have all the parts to go but I dont know how to setup my computer. Yes I have read all the grbl and wiki sheets and they dont help.
I would like someone to say "plug this here, type this here, do this and that" so I can get this going.
I have a CNC machine. If you're DIYing your own, it's not a simple plug and play. You're in for a world of surprise if you think it's that easy as buying the parts and hooking them up together.
I bought a ready-made CNC with it's own motor controller, hooked up via LPT port to a Windows computer. Then I'm using Mach3 software to control the CNC machine. The Gcode is generated by another software (forgot the name, EasyCAM or something like that), which takes a DXF version 12 file, which is created from/exported via AutoCAD software.
I draw the plans in AutoCAD, export to DXF, import DXF into EasyCam, assign tools, depth, cuts to each path/layer, export Gcode, feed the Gcode into Mach3, click Start and off the CNC machine works.
I have no idea how you're going to do all that CNC using an Arduino and some shields only.
Once you have the CNC running, you're still not out of the woods. You'd then have to figure out the proper cutting speeds and depth for each material type you want to mill. Expect to break a lot of router bits (at a cost of $25 to $50 each) as you're experimenting. Then you need a bunch of miscellaneous stuff, fixtures, jigs, etc.
Do you think this is easy?
