General Mach Discussion / Re: Z-axis Auto zero wiring

Hi Dan,

The 'auto tool zero' is accomplished when the touch plate(which is positive) is pulled to zero when in contact with the tool. Therefore your input pin 12 has to be pulled high (this can be accomplished by changing the jumper X5 on the C10 board).

CNC4PC do give instructions for setting up and using auto tool zero with the C10 here:-  http://cnc4pc.com/Tech_Docs/C10R10_USER_MANUAL_V2.pdf

Thanks for the suggestions / ideas - anything and everything is appreciated. I have just so much learning to do here.

Hi Dan,

Yes it does have a draft angle because the beam converges from the lens to the exact focal point whereupon it diverges again. I am currently looking at ways to improve this situation either by using a lens with a greater useful focal length or multi-pass cutting at reduced power with Z movement resetting the focal distance on each pass.

The edge finish is not perfect with some vertical styrations similar to a bandsaw cut but at least it is polished and so looks acceptable - I need more practice and experience here !.

The picture was taken with flash and the acrylic is on a sheet of brushed alluminium - Quite a nice effect I thought !.

I will post some more pictures when the camera battery has been recharged.

By way of an update on this project:-

The DRO struggled to display the tube current a low power settings and has been replaced by a retro moving coil panel meter straight out of the 1960's. A new scale was engraved with the laser and a suitable shunt fitted to calibrate the meter.

   

This is my first attempt with cutting acrylic. The red is 2mm and the clear is 6mm thick.

Hi Sam,

I export as HPGL (which is where the arcs become the many straight lines) then convert this to the GCode with a simple converter program.

Seems that Rhino is looking at a different file or getting it's data from the registry settings perhaps.
