The basic circuit I have in mind would look something like this.

Change your limit switches AND e-stop to active low. Reconfigure Mach input signals accordingly. (You may need to use pull up resistors to +5V (not +12V) on each of the limit switch and e-stop inputs).

This stuff is the other way round - black on the outside and white in the middle.

Hi Dave,

Could have saved you a lot of work if you lived in the UK. I've just taken my mini mill out of its enclosure which is now awaiting the scrap man.

Regards, Tweakie.

Brilliant machine and expert programing, I just pity the poor old electrician trying to get  his wires down that conduit.

Hi Dave,

I assume you mean the pencil.

The tag is 'Trafolite', which is an engraving laminate - this one is white on the outside and black in the middle, you just engrave through the outer layer and bingo. Its available in all colors and color combinations. It must be known by a different trade name in the US.

Regards, Tweakie.

A really silly thing.

First the engraving in Trafolite then profile cut to shape. Pocket milled the pencil then inset the piece.

Has anyone done anything more useless than this ?.

General Mach Discussion / Re: Software to convert Dxf to Gcode, aka CAM. Recommendations wanted

I use CamBam for dxf to GCode - it's also extremely good at creating the tool radius offset paths. Easy to use and fully supported by active forum and it's Free.

Teak, being a particularly oily wood, does not take too kindly to double sided sticky tape - so I thought that the vac table would hold it better. Unfortunately the teak blank was not flat enough and moved during the first (particularly savage) cut. Luckily the through hole (just below the letter E) can be easily filled and the job was completed on the reverse side using double sided sticky tape after all. Let this be a lesson to me.

This is nothing special but I thought you guys may like to see the photo's.
