Vince,
Thats to bad
Maybe you can find a scematics on this forum.
So maybe that you then can build a board for your own.
Else,
You have to wait for the Skyko's.
I assume you do have already the amplifiers?
Then we are on the same line :P
I'm in the same stadium. And Rutex is sleaping for several years now.
I hooked up my machine to a MEI card for 4 axis interpolated motion now.
We keep on waiting...
I received a message from Richard at Skyko that he had just got back from vacation. I tried to reply to his email several times and I keep getting the bounce message:

Are the pixies ready to sell yet ??? I have been in skyko web page, but there is no new information.
My Pixiw 100 boards shipped today. I should have them by the end of next week.
Vince
Hi Guys,
I just received the new Pixie P100 boards from the pick and place company (who does great work btw!...I have hand soldered several of these boards before and it is NOT fun). They are testing out great and I have plenty in stock now. Sorry for the long wait, next time I will try and order more before I get too low.
Thanks,
Rick
I received three Pixie 100 boards and hooked them up to my Servo Dynamics drives. I am able to rapid all the axis at the same time at 200 ipm smooth as glass. I could probably go to 300 ipm, but the mill is still up on 4x4 blocks waiting for a move. They saved me about $400 over replacing the SD drives with a step and direction drive.
Vince
Okay!
That sounds like music to me!
What encoders do you use?
I posted this on another thread, but it has merrit here about Pixie drives:
I have been getting more into the controls now that the machine is running well. The Pixie cards can all be wired together so that when one faults, they all fault. I decided to wire them this way for safety. For instance if the Z axis faulted when it was supposed to retract, the X or Y axis could crash the tool. The Pixies can also be wired so that when you reset one, they all reset. I did that as well. I mounted a lighted switch on the control panel so that when a drive faulted, the switch would light up. Pressing the switch would reset the drives. I needed some way of having the Pixie light up the switch. I found the solution at http://www.cncbuildingblocks.com They have a 8 relay board that will take a TTL signal and control a relay. In addition to the Pixie being able to fault each other, any of the fault signals can also supply a TTL signal at the same time. The relay board arrived yesterday and I wired it up like the manual said and it worked the first time. My lighted switch had a 120V light so that is why I needed the relay.
After playing around with it, I found that I had another problem. If the servo drives are enabled and the Pixie’s are faulted, the motors will creep. I thought about it over night and when I woke up this morning I had the answer. If the Pixie TTL output could drive a second relay, I could use that to tie into my EPO circuit which disables the servo drives. It also has the added benefit of shutting down the VFD that is driving the spindle.
After work tonight I wired in another relay to the Pixie fault output and tied that relay through the EPO wiring. It all worked. Now if a Pixie faults, it shuts down the spindle, servo drives and lights up the switch.
Vince
The Pixie *does* have an enable output to the servo amplifier that can be configured active high or active low. When the Pixie faults it will toggle this enable line to disable the amplifier (assuming your amplifier has a ttl enable/disable input).
Did you get the Brushless motors to run? If so do you mind telling us what you are using. I bought some of the same 1Kw motors thinking I would use the Rutex 2030 drives, but I am waiting to see if they are going to stay in business or not. I currently have DC servos working with the Rutex 992H drive and am content with there operation.I have found hands down the best source of motors and amplifiers to be ebay - if you know what you are bidding on. That surplus center deal on the Sanyo motors was also nice, but those don't come around so often (I only bought 6 of the 1kw motors)

I try to contact with skyko for pixie p100 but I can't. I saw Rutex's R991H High speed servo motor drive - analog output. Is it compatible with mach3? I have sanyodenki drive waiting for retrofit.
I have been trying for several weeks to contact Skyko but all my emails get bounced back. I received my Pixies (which are beautiful) but I was after a wiring diagram.
On the other hand, you have to give the guy a break. This is a sideline that he really does not make any money on, but, just does it as a service to the CNC community. I'm sure that after he gets whatever he is working on resolved, that he will join us again and Pixies will flow once more. Patience is a virtue.
