Stepper motors for Torch Table are from Xylotex.
Possible limit switch configuration:
Setting fractional steps on stepper motors:
- 1/4" shaft
- 425 in oz torque
- about 50 W power usage
The XS-3525/8S-4 microtepping stepper motor driver is the perfect choice for CNC retrofitting of desktop and small benchtop milling machines. Connect bipolar wired stepper motors, power, and parallel port signal source.
- Small Size 4.275 x 2.8? inches.
- Drives up to 35 Volts @ 2.5 A/phase
- 4 different microstepping step levels from Full-Step(FS) to 1/8 step
- Filtered & Buffered Step & Dir lines
- Built in DC-DC converter for +5V
- Break-out screw terminals for I/O
Microstepping Truth Table
1 means jumper NOT installed
The XS-3535/8S-4 Stepper Driver is a 4 axis pulse-width-modulated (PWM) current controlled bipolar micro-stepping controller. Each axis drive has a +-2.5 Amp/phase @ 35 Volt maximum continuous Output Rating. The drive circuitry has thermal shutdown protection and crossover-current protection. Synchronous rectification circuitry eliminates the need for external clamp diodes in most applications. Each axis accepts Step & Direction signals, along with 2 jumper inputs to define microsteps per full step.
The board is of 4-Later construction with Isolated Power and Logic supply planes. The drive circuitry has a heat sink attached to allow cooler operation.
