Description

What’s makes the HobbyCNC EZ Board Kit different than others?

  • HobbyCNC EZ is easy to assemble as part count is very low. Lessens chance of assembly errors.
  • 36VDC maximum input gives a very wide margin to help prevent damage with voltage surges.
  • Smaller footprint for EZ installations.

HobbyCNC EZ Board Specifications:

  • 3 Axis Unipolar Chopper control.
  • Individual OR simultaneous control of 2/4 Phase Stepper Motors.
  • Accepts 5, 6, or 8 wire stepper motors only. 4 wire types are not usable.
  • 36VDC maximum input voltage, 12VDC minimum input voltage. 24VDC Minimum Recommended Voltage.
  • 3.0 Amps Maximum per Phase, 500ma (.5A) minimum. Each axis adjustable throughout this range.
  • 1/1, 1/2, 1/4, 1/8, and 1/16 Microstepping.
  • Step and Direction Control.
  • Built In Protection Circuit to help against blown chips on stepper motor short or open connections.
  • 3.6″ by 4.8″ double sided with top silkscreen and thru plated holes and lead free solder PCB. (RoHS compliant).
  • Power On Reset.
  • On board voltage regulation for 5-volt logic with 24VDC cooling fan from motor power supply.
  • On board connections for home and limit switches with 10K pullup resistor provided to each. No need for a separate “break out” board.
  • Minimum of components to make assembly fast and easy!
  • Works with Step and Direction software such as LinuxCNC, DeskNC, TurboCNC, Mach3 etc
  • RoHS Compliant
  • Compare product features

We recommend a 24VDC to 36VDC power supply rated at 8A minimum. Higher voltage power supplies are NOT recommended!

What power supply do I need?

We recommend at least 36 Volts DC, and 3 amps per stepper motor. For a 3 axis board, a 9 Amp supply minimum, for a 4 axis board, 12 amps minimum. Never exceed the rated input voltage for the HobbyCNC board.

Is a special cable required to connect to my PC?

Yes. This is VERY IMPORTANT. You MUST use a 25-Pin, M-F, all wires, wired straight through. This is typically (but not always) a parallel printer cable. We sell a 6 and 15 foot Parallel Printer Cable that is tested and works!

My PC doesn’t have a parallel port

You will need to get to the equivalent of a parallel port somehow to secure the required “Step and Direction” signals. There is more detail in the FAQ Options to a Parallel Port.
