Arcsin Proto 2!

HOME

Arcsin basking in the sun. These proto pcb's are first rate quality and I am thoroughly impressed. Thanks PCBFabExpress!

 

Arcsin heatsink was milled on my IG-88 cnc mill under the control of an Arcsin board!

 

We've really put a lot of thought into this board and I'm sure you will agree that it absolutely rocks!

 

Want to see how fast you can spin your steppers? The Arcsin max step rate is nearly 32Khz in 1/4 step mode. At this rate, you can see that the motor speed is ~2400 rpm. This test was run with a nema23 triple-stack 300oz/in motor.

 

You can see on the frequency counter that we're driving the Arcsin at nearly 32Khz.
