DAMN,

My A3977 controller is still a few months away.

> Hi All,
>
> PMDX is finally ready to release the
> PMDX-150 stepper motor drivers that
> we have shown prototypes of at earlier
> shows. The PMDX-150 single board concept
> has been repackaged as single axis boards
> and a motherboard.
>
> Key features are:
>
> Based on the Allegro A3977 microstepping chip.
>
> Current from 3/4 amps to 3 amps (with fan cooling).
> Current set by dip switches.
> Step pulse polarity is dip switch selectable.
> Auto idle current reduction, with dip switch enable.
> Opto-isolated step, direction, and fault signals.
> Step and direction are ground referenced and designed for
> easy drive from laptop or motherboard printer ports.
> The opto-isolators do not need a 5 volt power source.
> Single motor power supply voltage, no logic supply needed.
> On board, self resetting fuse.
> On board power supply filter capacitor, no external
> capacitor needed when using long power leads.
> Over-temperature shutdown and lockout.
> Overvoltage protection for spikes and back EMF.
> Protection against spikes from unplugging motors with power on.
> Push button test to run motor without computer.
> LED to indicate activity and fault conditions.
> Seperate pluggable terminal strips for motor and interface.
> Designed to allow panel mount with direct motor connecter access.
> Supports micro-stepping and step multiplication.
> Eight micro-step, A3977 native
> Quarter micro-step, A3977 native
> Half step as 4x multiplied eight micro-step
> Full step as 4x multiplied quarter micro-step
> Priced at $65.00 each, limited quantities available at
> the Cabin Fever show. Full production in early February.
>
> A motherboard/power supply, the PMDX-130, is available to
> simplify wiring and packaging. Key features are:
>
> Holds up to four PMDX-150 boards.
> Has Centronics style parallel port input connector.
> Allows mounting of input connector and motor connectors
> directly though your panel.
> Accepts 12 to 24 volts AC and converts to DC suitable
> for powering PMDX-150 boards.
> Alternate version available for use with PMDX-120 if
> you populate the 20 pin ribbon jack for the step/dir
> outputs of the PMDX-120.
> Provides interface signal when any PMDX-150 faults or
> if power is removed by shutdown or emergency stop.
> Provides power for DC fan.
> Pricing to be determined, available early February.
>
> We will also be showing a complete boxed unit at Cabin Fever.
> It has a case, motherboard, PMDX-150s, power transformer,
> switch/circuit breaker, emergency stop switch, a fan, and
> an accessory outlet controlled by the emergency stop switch.
> Pricing to be determined, available early February.
>
> PMDX and the Chesapeake Area Metalworking Society will be
> supporting a CNC demo area at Cabin Fever. We expect several
> CNC mills and a CNC lathe to be up and running. There should
> be examples of TurboCNC, EMC, and Mach2 on display.
>
> Looking forward to seeing you there. Please forgive me if
> I do not respond to questions until after the show, as I
> will be working from now until then to be ready for the show.
