Re: T-Slots or peg holes?

This sort of clamp looks like a good option instead of wedges.

Re: Inaccurate Z depths when running straight line tests

This is not related to your original problem, but one thing that I noticed about your Gcode, is that if you are running a Quiet Cut spindle from Inventables. Then your spindle speed is set way too low at 1000 rpm, (M3 S1000), try setting it to something like 12,000 rpm and you should get some better...

Re: L5R Card Guard

Cool! looks like I have some experimenting with v-bits to do.

Re: L5R Card Guard

Using a V-bit when engraving or carving allows the machine to lift out along the corners and intersections, making it possible to reduce the effective radius of the cut, resulting in finer details. I get that bit, but wouldn't you use a ball or end mill to rough out the pocket and then finish off w...

Re: L5R Card Guard

Pretty good indeed for a couple of hours work.

Whats the reason for using a v-bit to carve out the pockets?

Re: CNC facilitated bribery

Thanks Gadgetman, I haven't really re-tightened or re-squared my machine since I built it. I think you might be onto something with using weights to damp out vibrations. Any advice on suitable spindle speeds with the Quiet Cut Spindle?

CNC facilitated bribery

After spending all the time & money to get my SO2 up and going, I thought it would be politic to get the kids on side ;). So my first big project was a dolls house and matching furniture.

Re: Acessing A5 pin for probing when using gshield

Actually, on closer inspection of the 2nd photo, I did, just what bengtec did, except that I used female headers instead of male.

Re: Acessing A5 pin for probing when using gshield

Your photos gave me an idea. I didn't want to desolder the Arduino header pins. So I took a female header block, stuck its pins into the existing analog header block and bent them to a right angle. I then insulated the exposed bits of the pins with some heat shrink. The results look similar to your ...

Re: Acessing A5 pin for probing when using gshield

I suspect you're right. But using a shield with all the headers seems like a bit of a waste for only 2 connections
