I finally got sick of diddling around with diode lasers , bit the bullet and got a k40 .
I must say wow ,why did I wait so long . I love the power .


I might need to modify the pcb , not sure if its best to supply the 5v vdd to the a4988's from the pokey [as it is now] or to supply it from the 5v supply from the k40 supply . its seems to work ok either way

I kept the pokeys out of the k40 box so I can use it in the 3040 mill

Hi Jim:

  Thats great!. Always nice to see another laser online. I love the power too, so much I now have 3 lasers in total.
( 14 watt, 36watt and 48 watt).

  Would it be possible to post the schematic of your interface board? This is one of the projects a lot of people
end up looking into over time and the more info we can archive on making a k40 run on a pokeys the
better.

Great work as usual...

here is a schematic of the latest revision , I did the pcb with diptrace and can make the files available on request
the procedure is not difficult the part no's for the connectors is in the k40 bob  post by , glennd
