Shipping is more like $30USD for the driver board alone. $60USD for an entire package including 3 or 4 steppers, driver board, wire, switches, etc.
Nothing we can do legally to reduce your tax...

Just get the "package" as mentioned above. All included except the transformer and case. Links on our product page

Our PRO boards have MUCH less hiss than the older 4AUPC boards. Allegro has done their homework on this.

Patrick,
Not quite accurate. Also, it was made very clear to me, that I was not to exceed the 10A
limit or again, smoke would roll. The transformer voltage you intended to use will smoke the...

Sale has ended.
Thank You for your support.

The HobbyCNC Pro board does NOT require a BOB!

This wouldn't be the driver board kit you claimed you never rec'd is it?

WHY would you need a power supply for a driver board kit you claimed to PayPal you never received? Or is this the replacement we sent that you also claimed you never received?

You're incorrect!
The $280 is for a "PACKAGE" and the $214 is for driver board and steppers ONLY.

How much did they save?, about $40.00? How much will it cost them in "Bad Advertisement"? The board was bought about two months before....

I guess jhowelb forgot to let anyone know we did...

You also missed our post about our internet connection being ripped from the house in the last snow we had.

Enjoy.

Folks,
Our Yahoo hosted support group is the best place for timely replies. I have to answer the same questions twice as many get posted here too.

We will rarely check this forum in the future....

I'm going to guess you missed MY post on our support group about our internet connection being ripped from our house along with the 220VAC service? Just now getting back to normal.....

Nope.
Reread the step about the voltage check before installing the chips. It gives a clue as to what components to check. LOOK very carefully for poor solder joints and/or bridges.

Between 12 and 42VDC input MUST show 5.0-5.2VDC at the +5VDC pad.

Bobby,
Look closely at the "minus" sign. I'll bet it is a wavy line signalling AC. I've attached a PDF and a JPEG that shows the rectifier "pinouts". It is a sectional cut from the package wiring...

John,
To refresh your memory. (I've bold faced the driver boards)

John,
The "REV2" is the older design. The REV1 board is our newest release due to newer chips available.

You're free to do as you wish.

John,
On 8/19/06 you ordered a HCNCPRO kit with steppers. This is the REV1 board. Our latest release with newer drive chips (23pin).
On 9/27/06 you ordered our 4 axis 4UAPC board. This is REV2. ...

The difinitive lesson:

http://www.cs.uiowa.edu/~jones/step/

We recommend a 24VAC 10A transformer be used in all cases, 3 or 4 axis. We find the 10A cheaper than an 8A here in the States. This allows upgrading to a 4th axis in the future. 13A tranny is NOT...

Have you looked at the HobbyCNC UK Transformer thread in our forum here on the Zone?

U5 the LM317 controls the +5VDC. Maybe you have a solder bridge that overloaded it. Or maybe simply a component failure.
Private mail us your address and we'll send a free replacement.

Turn it off and then on again. The chips MAY have gone into "protect" mode. A copy/paste from the instructions:

"If the driver does enter fault protect mode, then cycling the power off and on...

Same performance can be expected as with the SLA7062M driver boards (4AUPC)

Added features of the PRO board are:
Idle current reduction after 10 seconds of no movement for each axis. Can be...
