Hi Dave,
have you heard of a "PE Sync" problem with the 12T/47T ratio ?
I came across this thread where he mentions it and therefore has gone for a 4:1 ratio.
I know its been mentioned that this mod will work without any modification to tracking rate in eqmod, but I'm keen on using PEC as well. not sure if this is going to be an issue.

Can you please clarify.
found the ratio's of the spurs
- stepper gear (12 teeth)
- transfer gear (36 teeth)
- worm gear (47 teeth)
and the 47T/12T has the same effective reduction, but not sure what this sync issue is.
Cheers
Alistair
