Hi Matt
I am in Sydney, I'm after a 40volts 600VA toroidal transformer or like you, 2x 300VA... Can tell me where you found yours? and also what kind of outputs it has. I found this on ebay but I am not sure if they are suitable: Toroidal 300VA, 40-0-40Vac It is centre tap 40-0-40 output. There are two modes of connection. Mode A (Series for Double Volts) 3.3 amps Mode B (Parallel for Double Current) 6.6 amps thanks, Francis by the way, I bought the motors from MS they look great. http://www.mechmate.com/forums/showthread.php?t=2214 |

Hey Francis,
Sorry, not sure how i missed your post. I bought my transformers from Altronics. http://www.altronics.com.au/index.as...=item&id=M5535 I'm no expert in transformer wiring, but I didn't think a centre tap winding will be sufficient. When you parallel the windings you need to connect the two starts and two ends of the windings, but thats not possible on a centre tap as the start/end the two windings are connected. Good to hear your happy with your motors. Can't believe you're using such are large module rack! |

HI Again
Hi Matt,
sorry about all the questions, Could you indicate details of the stepper motors you are using? How are they going for you? About at the stage to order stepper motors. Looking at MotionKing 34HS9801 however should consider suitable steppers from another source. Any comments on source, part number approx. cost, delivery issues? Feeling godd bearings arrived this morning. steel parts are cutout but not bent yet. thanks Graeme |

Thank for that Matt, our USB to RS-485 converter's should be here any day now. And when feeling better I can finish wiring up the BOB's and everything else I can build the coolant flow sensor circuit.
And I forgot to say feed the fly pigs. (I got a lot to do) |
