I plan on using a modified Dremel 395 as my spindle motor. I have removed the Dremels internal Triac based speed
control as the internal motor is a universal motor that will run on AC or DC. I added a IR LED and a Phototransistor to
the dremel motor to send a speed pulse back to Mach3. I removed the AC power cord and added a 5pin CB radio type
connector on the rear for the 2 wires for the motor and 3 for the speed sensor system(details on that later...thats next).
Hi Zero Cool!
Thanks to share this with us.
This is a really great schematic, I have looked for during 3 days before finding something interesting,
so do you have more info about the IR LED and the phototransistor?
I am ready to order at Digi-key but I don't want to send my order before be sure about the ir led and phototransistor.
I see that the post is almost 1 year old but I wish to have some news soon
Thank you and have a great time
Sly
