The controller was all ready programmed.

It was already programmed, but still needs the jumper pins configured for your particular clock. It ships with all the jumper pins fully populated. Several jumpers will need to be removed to set the exact speed needed for your clock.

This thread also answers the same question and adds pictures. https://www.stevesclocks.com/forum/electric-clocks/silent-shield-board-pin-locations

The default program supports several different clocks with slightly different gear ratios. The jumpers need to be configured for your specific clock. Also, 400 step motors need different jumper settings compared to 200 step motors.

Look for the speed selection table in the manual and make sure the jumpers are set properly for SP10 with the 200 or 400 step motors that you are using.

There is a small typo in the manual. It should look like this:

Okay I figured it out the diagram on page 52 shows 3b on right hand side should be 7b.

The assembly guide at https://www.stevesclocks.com/sp10 has been updated to fix the typo on those gears. This change is so minor that it is not worth printing the entire manual.

There are some new diagrams on page 51 and 52 that might be useful to print just those two pages.
