Title: PEC and VSPEC
Post by: pterodyne on August 07, 2018, 20:48:19
Tom, as always thanks for your time and dedication to this project!

Something I haven't messed with yet, but plan to now that my Titan mount is astroEQ based:

Because our AstroEQ mounts have various and different worms/gears/pulleys/ratios and microstepping modes, does eqmod PEC routines work as expected?  What if anything should change about the workflow as described in the VSPEC manual?

Thanks for suggestions!

Hi Bryan,

PEC functionality in EQMOD should work correctly with the AstroEQ.

The config utility calculates an "sVal" which corresponds to the number of worm revolutions per mount revolution. This is reported back to EQMOD to allow for PEC period to be calculated. The same process as is used by Skywatcher mounts.

Kind Regards,
Tom.
