3-axis bipolar microstepping motor driver with integrated joystick control!
- 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.
- Full, half, quarter, and eighth microsteps switchable with onboard dipswitches.
- Simple, accurate current setting by means of standard 1/4w resistors.
Resistors plug in (easy to change, no soldering).
- 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.
- Parabolic ramping algorithm on joystick control for higher motor speed and silky smooth acceleration. Can be enabled/disabled via onboard dipswitch.
- 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 configurable to any percentage by means of standard
1/4w resistors which plug in.
- 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.
- Expansion connector header for connection of additional interface
circuitry if desired.

Ahhh Yeahhhh!!! The first cuts with the Arcsin controller!!!
The dual drives are almost ready to go. Now you can run 2 motors on the same axis!!
Prototype 2, this is IT!
Prototype 1 is looking good!
