3-axis Bipolar Microstepping motor driver with integrated joystick control!
Proudly Engineered and Manufactured in the United States of America
Yes, it's back! The Arcsin is now smaller, faster, packed with more features and now comes with a chassis/heat sink to cool and protect all of the goodness inside!
Arcsin features:
- 3 axis bipolar microstepping motor driver.
- PWM (Pulse Width Modulation) technology.
- 20Mhz onboard microcontrollers for precise digital control.
- Fixed off-time current chopping. No bulky series resistors needed between the controller and the motors.
- Jumper selectable full, half, quarter, and eighth microstepping.
- Output current adjustable with plug-in resistors.
- Fully integrated digital joystick control for accurate positioning of the cutting head. All three axes of the Arcsin can be run without a PC for testing and/or motor spinning.
- Joystick speed potentiometers for each axis, or you can jumper them together so a single pot controls the speed for all three.
- All DMOS H-bridge power section delivering 3A per phase continuous(6A peak) at up to 48V.
- Idle current reduction after 5s of no step activity.
- Thermal shutdown @ 155 degrees Celsius.
- High speed Optoisolators on step/dir signals to reduce signal noise and protect PC.
- Separate power planes for logic and opto supplies that can be jumpered together or split for ultimate noise suppression.
- Onboard 5v regulator for Logic-supply.
- Ribbon cable connector for additional slave driver when 2 motors are needed for a single axis.
- Direct parallel port connection.
- 30Khz max step rate.
- Optional C axis step/direction outputs.
- Opto-isolated 12v @ 1A spindle motor and coolant pump output transistors.
- Home, limit and Estop inputs, all opto-isolated.
- Heat sink integrated into chassis.

Arcsin FAQ's
I just had to include a shot of the finished Arcsin running my Shrapnel 3-axis CNC milling machine!
It has been so much work to get to this point that now I can't remember if I built the Shrapnel to showcase
the Arcsin features or if I built the Arcsin to showcase the Shrapnel!
