sorry Snow.

1. no tried again with a different file.
2. yes, cut, then frame. its a time lapse.

I did some testing tonight and all is good until i zero off the laser pointer.
The code i'm using for this is
G92 x0 y0/ G0 x-2 y 104/G92 x0 y0

Is this code wrong?

Also, everything is fine, until I zero on the laser pointer. 

Hi all 
I need to order a 7i73 and shipping is $90 USD to get it to Qld Australia. This may be the unavoidable cost but I can't justify it for a $49usd board.
I'm happy to wait a couple of months if necessary and combine freight with others ordering from Mesa.
If your considering ordering and would like to combine our orders and split freight costs PM me. 
Cheers Brad.

Fixed the link formatting.

Not sure what has happened to that link? but it still works?

Hi Stenly, I bought these Signal converter . They cost a lot more than I wanted to spend but at the time I thought I was going to get it going quicker. Approx $130USD each. The Aikron ones might be worth the gamble. Or if you are more tech savvy than I am currently then the ones jochen has linked would be a option. Here is their reply to my email for the ones I bought.

"Your calculations are very helpful.  The HEIDENHAIN LS 486C has a 20µm resolution glass which, as you correctly calculated, will produce a 10Khz signal at 12m/min.  I have attached a data sheet showing the federate limits of each interpolation version for your reference.  You can choose any interpolation option from 0.5x to 5x.  The 5x interpolation model (SA 1872) will provide you with a 1µm TTL output signal. "

In all likelihood they just have the chip jochen has linked

Got it to build. The install script, as far as I can tell it doesn't bring in libclothoid3d and libscurve
When I did that manually (path here forum.linuxcnc.org/38-general-linuxcnc-q...orm?start=170#323932) and copied that to the empty directories the code builds.
