Here are pictures of the test cut that I did to really put the CNC router to. Goal was seeing how well it cut and what the result would be from the required ability to:

Not lose steps (position loss)
Run at speed
Finish of work


It passed pretty much cleanly with only a few problems with the Ethernet card and that is being dealt with by Smooth Stepper and I have to say that they give very good support. Due to the few minor issues I was able to truly test the positional memory of the machine as had to restart cuts at a few locations.

The item below was cut under the following conditions:



Rapids where at 8000 mm/min Velocity with Acceleration of of 1250 mm/sec^2
Cutting was done at 950 mm/min and plunges where done at 850 mm/min
Bit was a 60 single spiral flue engraving endmill from Sorotec.de
Cut time was 2 hrs and 43 minutes plus time for starts and resets.
Material is smokey translucent acrylic that is 10 mm thick
Deepest cuts are i believe to be about 5 mm.


So here is the pictures. 68786879

Hope you enjoy and I will try to remember to take some video when doing other cuts.

That acrylic isn't backing it's actually the material it's cut into.? . . . .Looks like aluminium at first glance doesn't it.!!

Got it as off cuts from a company in Livingston out in the Industrial park out there. I would have to go back through the receipts to give you an exact name for the company. 10 mm thick stuff and got it rather cheap.
