Pks-digiplan sd2 driver IC help please

[i2i]

The Triac does use the sd2 drives on the x and y axis, and an sd3 on the z axis. This is on models up to the early 90's, and then they changed them to the sd12/13 drives.
Is your Triac one of the green ones with the open frame or a mixed white and green one?

[asto]

Yes right! The green one.
But painted Grey.
An old open machine from the 80's.

i2i...Do you want to sell any of these boards?

cheers

lovely machines the old ones i prefer the 3 phase spindle motor to the dc motor on the newer models, but such a shame they came with the r8 spindle nose. The newer ones have a 30 spindle that allows the bt30 tools and an atc.
Now a mod to use the r8 spindle and convert it to a 30 taper and atc would be handy.
My stock of cd20s are to backup my 2 Denford Quatros and my easiturn, they are quite hard to get hold of and that's not going to get better, so sorry i'll not be parting with any.

My apologies if i came over a bit high handed in earlier posts.

i2i, just as an independant observer, you did not come over as "high handed" in your posts, just as someone who knows what he is talking about!!! G.

...My Triacs are not R8 machines I have two of them. One was built in 1985 and the other 1987. The newer I bought from G and m tools but Z axis failed after a while.Thought it was the stepper motor and replaced that with new Sanyo. Then I found the L298 dead.
Replacing this IC was not that easy in double sided board.

Sorry about the first picture. It was not taken from my machine. You were right.

cheers
