KStep — 4-Axis Microstepper Amplifier for KFLOP/Kogna

Click for large photo.

KStep is a KFLOP/Kogna expansion board designed specifically for plug-and-play stepper motor control. With only a motor power supply, stepper motors and the KFLOP/Kogna+KStep you have all you need to start controlling 4 motors (or 8 with 2 KSteps).

This ease-of-use also comes with high performance, high efficiency, and additional 12-24V isolated I/O expansion sufficent for most applications. Although it is possible to use third-party stepper or servo drives with our KFLOP/Kogna controllers, KStep provides complete connectivity with a single ribbon cable connection, easily mounts to KFLOP/Kogna with standoffs, and gets the most out of our software. In addition, KStep's ultra low resistance MOSFETS eliminates the need for special cooling and heat sinking. This setup reduces cabling and wiring and puts everything you need into a nice footprint. KStep really is a culmination of many customer requirements in one expansion board.

Software:

The main strength of Dynomotion's products is the comprehensive level of software support. From the flexibility of the low level programmable FPGA logic, digital signal processing routines, real-time multitasking programs, host motion control libraries, interpreters, compilers, .NET interface, examples, mach3 support, servo tuning and analysis tools, and supplied host applications.

Example Applications:

Most anything using 200+W Steppers
CNC machining:

Mills
Lathes
Brakepresses
Grinders
Spinners
Routers
Saws

Robotics
Automation
Camera Control
Pick-and-place
Data Acquisition

Example Input/Outputs:

Size 23 Stepper Motors
Stepper Motors greater than 5A are ok, but current is limited at 5A which is generally not a problem
Simple sinking 24V Limit and Home Switches
Spindle controls with 0-10V analog input

Not to be used with:

Supply voltages lower than 12V and higher than 48V
