If you are using the rev10 board then you have to have the input pins configured to 'pull-up' if your probe completes the circuit to GND. Check out the PDF Manuals here http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45

What really peaks my interest, is how much detail a person could get into that part if it were anodized and dyed black, and you had, say, I dunno....a cnc laser or something.   If I could somehow justify the cost, I would most definitely like to have one!

Just think of it in terms of 'handbags' and 'shoes' and how many = 1 laser, then do a trade.  ;D

Hi Rich,

You may want to return to your thread and replace the description of exactly how your inlay work is done.  ;)  It would be most helpful for others that follow.

It seems that the posting relating to exactly how it has been done has been deleted ???

The reason I asked about the material is that on the photo above it looks like there is some transparent layer between the numbers and the background.

I think it's the lighting Dan. All the tests were done on the same piece of scrap but if the earlier pic was taken inside the workshop it may have been with flash.

Just for ref.    Top right is original M10/M11 : Top centre is B0/B1 : Top left is first revision of M10/M11 : Bottom left is final revision of M10/M11.

OK Sam spill the beans - How did you get that much swarf from one little engraving ??  ;D

Very nice though.

A lot of people are using the C10 - What is the problem you are having ??

Hi Gordy,

I think you need to look at your GCode syntax and check that it is all Mach compatible (GOTO is not good).

(If your machine stops at the line GOTOZ2.0000 now it would have stopped at that same line last summer).

Hi Dan,

That is just a piece of scrap MDF I used for testing.

There are quite a few problems associated with using an axis direction pin which crop up from time to time and eventually become a real pain.
As mentioned earlier the software polled EStop does not change the state of a direction pin but it can turn off an output thus using an output gives an added safety feature.
Feed hold, if it ever has to be used, creates another issue when motion stops with the laser still on - easier to handle an output than a direction pin here.
My B axis DRO can, in error, somehow get to a -1 step position then the B0 command that is supposed to turn the laser off actually turns it on - another B0 command does nothing to turn the laser off - only the separate commands B1 and B0 will turn the laser off.
At initial power up the state of an axis direction pin is not always guaranteed.
There are a few other issues as well so overall using an output for switching is far far preferable.
