I suppose 32 Volts from the transformer was a bit close to the 40 Volt max for my home made stepper drivers because today there was the inevitable mains voltage surge :eek:

It was like the bridge of the starship Enterprise when the Klingon disruptor hits, the steppers stopped stepping and smoke started pouring from three very defunct driver chips :(

Luckily I had bought three commercial stepper driver boxes (a Gecko by any other name would small as sweet) and a pukka power supply so I won't be down long. Nearly finished wiring it in, have to rewrite my program a bit.

I shall miss being able to save the stepper coil info for next time when I exit the program but I suppose you can't have everything.

Not a clue what you are talking about:confused: ; but shame about the surge. On the up side you get to use them lovely Gecko’s.:wee:

Hi John

Not Gecko's, something that looks like Gecko's :)

It's all together, can't decide if it looks like a Christmas tree or a mouldy bolognese, have to tidy that wiring up.

Code rewritted and I was just excercising it. Max forward to max reverse 5 times in a row. It goes clonk when it changes direction, think I must be over-running the acceleration table :confused:

Nearly there :)

They look like MSD drives I use from Motion Control Products.

Do you have a delay between direction changes? I have to finish tuning my X axis and am using a 100ms delay but want to get that down lower.

Good ol' Motion Control Products. Bit surprised when I rang up to buy, they didn't seem to know how to sell :confused:

No delay, I use an acceleration/decelleration table which sets maximum speeds when it is close to either end of the traverse. Only problem is, it doesn't seem to be working...

...yet :)
