Product Description

Description

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.

Please view our on-line documentation for full details.

Here are just a few highlights of the KStep:

  • Quad 240W Microstepper Amplifer
  • Plug-n-Play with KFLOP/Kogna
  • 16X Microstepping
  • 5A @ 48V Max
  • Super High Efficiency 17 milliohm MOSFETS
  • Opto Isolation
  • Mixed Current Decay
  • 500K steps/sec
  • Regenerative Voltage Clamping (1KW peak)
  • Includes 1 Opto Isolated Analog Output
  • Includes (16) 12-24V Opto Inputs
  • Includes (2) 30v @ 0.1A Opto Isolated Drivers

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

I designed and built a 5-axis hot wire foam cutting machine for a project at school. I am a mechanical engineering student, so C-Code and motor control was obviously not my speciality.
However, I still chose to buy the KFLOP and two KSTEPS, and I am extremely happy with my choice.
The documentation on the website is very complete. Each time that I had a specific question, Tom answered to me within an hour with THE solution to my problem.
The KSTEPS are running like magic. They produce almost no heat (Contrary to the normal Drives that I tried before).
In hot wire foam cutting, it is very important to have constant speed during machining. In the KFLOP settings, it is possible to adjust a «smoothing» parameter so the speed is as constant as possible. My motors are running so fine, it's like a melody when they change their frequency during the machining of a complex shape!!
Here's a video of our final machine:

I am currently completing my post-graduate work and I constructed a 3-axis milling machine as part of the scope of work. I initially purchased a motion controller and stepper driver that was recommended to me.
Initially it ran well and then the USB connection would disconnect and when re-connecting miss commands in the Gcode. There was no support for this product so I was stuck.
I then did investigation and came across the Kflop and Kstep. I wrote numerous e-mails to Tom asking question after question as I was nervous and worried that perhaps I was missing something with regards the other board. The pre-sales support I received was amazing.
I eventually bought the Kflop and Kstep once I received the funds from the university and all I can say is... Wow!!
The stepper motors run cool, the functionality to setup the hardware is great and the software KMotion and KMotionCNC is so easy to use.
I would highly recommend Dynomotion products. Excellent products and best in the industry support.
Thank you!! You saved my project!!

If anyone gives this product less than a 5, it is because they do not understand the technical aspects of this technology. No manufacturer makes anything even close to the capability and versatility these boards are capable of. Yes they are complex, however the rewards are great too using Dynomotion products. The quality of this product along with support (manuals and Forums) is superb!
I use Kflop, Kstep and Kconnect boards and they are worth every cent.

Very good experience with their KFLOP and KSTEP. The quality of the products is superior and the software is very user-friendly. I also got the best customer support I could ever asked for.

I'm old. I've dealt with all types. This outfit is the best ever. #1 by a mile.
I bought a KFLOP and a KStep to retrofit a router table. They provide limitless potential and cost much less than other alternatives. Every obstacle was caused by my lack of understanding. Support and product are flawless.
