Re: Tool length compensation

Thanks. I have a z homing plate so that is probably easiest.

Re: Testing and calibration

Dual Y motors is a very important upgrade. Before I upgraded mine, the racking was so bad it was almost unusable. Really loosening the vwheel pressure helps a bit.

Tool length compensation

Has anyone bothered? Or do you just rehome Z between tool changes? Just want to know best practices before trying a multi cutter job.

Re: Setting start Z height

I have a Z home switch wired as two alligator clips. One clips to the cutter, the other to piece of alum angle (3/4 or 1"). Place the angle on the work piece, jog so its close and press home Z. My home is configured to adjust for the height of the alum angle. I'm using LinuxCNC not grbl. From what I...

Re: Dual Drive Kit?

I'd like to be able to buy the upgraded motor plates. I plan on turning the spacers out of aluminum myself.

Re: What building materials you keep at home?

I bought a bunch of M3, M4, and M5 socket head from boltmax.com. Very reasonably priced and shipping seemed good. Arrived quickly too. Having a bunch of alum angle is really useful too. Usually 1/8". 1/16 can flex. Amazon seems reasonable but I have prime for free 2day shipping. I got a sheet of 3/4...

Re: Which electronics to use

I'm using LinuxCNC on my Shapeoko with a 4axis Easy-CNC driver. I'm really happy with it. It is much more capable than grbl. Probing works well. Spindle control should be easy, although I haven't tried it yet. I thought the build.log parallel port driver board had opto isolators, but I haven't looke...

Re: Digitizing probe + UNO ?

LinuxCNC uses G38.x for probing. Looking at grbl's gcode.c on github, it doesn't support that gcode.

You you're simply trying to set z height, you could wire it as a z limit/home switch.
