Max Stepper

4 AXIS SERIAL STEP MOTOR INDEXER

Max Stepper is a RS232 stepper controller indexer. It was designed to used by programs running under MS Windows.  Its frequency output remains consistent regardless of OS timing.  Commands are sent from a PC serial port to Max Stepper. Max Stepper will send step, direction and enable signals to 4 motor driver boards. E-stop and limit switch signals are brought into Max Stepper to stop motion signals. PC software can poll Max Stepper for e-stop, limit and auxiliary digital input conditions. The auxiliary digital outputs (for relays) and analog signals can be set by the PC. For a complete CNC system you must supply a PC and 4 Stepper Motor S/D Drivers to interface with the motors. Max Stepper will not connect directly to the motors.

MaxStepper News:

Important Note-International MaxStepper units do not include power supply.  A 9 VDC 200 milliamp power supply must be provided by customer.

Important Note-Currently Maxstepper will be shipping with 4 foot serial cables, not 8 foot as described in manuals.

AVI of Gantry Table in motion using MaxStepper (2.8 Megabytes)

The Gantry was moving up to 35 IPM.  The lead screws(1/4" 0.05 lead) provide 4000 steps per inch, so 35 IPM=2.33KHz.  MaxStepper can go much faster than this. Jogging one axis I can achieve almost 100 IPM before stalling due to motor torque and lead-screw limitations.
