Fare enough ! G202 it is even the though the specs look the same

But reading it a second time I do like those words
"Short-Circuit Protection" .
I was looking at the features of the 210 "Full-step, Half-step, 5 and 10-microstep Opto-isolated step / direction" not that it meant that much to me

With the Campbell breakout board would you request the Combo?

?
As for the scope well here it is:
I was a design engineering draftsman some years ago that used Microstation as a design tool with some 3 D modeling work ( need some refressing ,still have all the hardware and software)
I am involved ( getting back in as I now am older ) n historic motor sport and all the parts are hand milled, folded or turned in Aluminum.
Some of the parts are no longer available or worn out so making them is my next option. I would like to try lost wax casting ( CNC milling the investment mold from wax and then casting the piece )
I know that I could mill say the cam covers and dry sump from solid Aluminum always an option but its the cast look that I am after. I could also look at milling a reverse mold of the cam cover which would allow me to vacuum form a carbon panels positive from it. All work could be milled from jewelers wax blocks before being used as a die or real working piece before forming. I cannot see myself making parts larger than this.
Since there are parts available I was looking at somehow

digitising existing parts into Microstation or back into G code model then importing back into CAD as a wire mess or solid model ,tidying / sharpening the part up ,adding or fixing the breaks and faults and then finally milling the wax original ready to be zircon coated , burnt out and cast in RZ5 alloy. Well that the plan. Simple isn't it
