Hello
I tried this night to do a PEC with the CPWI software.
Do you need a camera connected to the CGX-L mount to perform a PEC?
I gave impulses to center the star but the green bar after 15 minutes to continue and nothing happened.

Good day

Hi!

 

I gave up on training with CPWI.

 

Try Celestron's free PEC Tool.  You can read and save what the current PEC curve is that way (it's stored in the motor controller of the mount, not CPWI itself).  Installing it needs compatability mode, but the program runs just fine once installed.  The program hasn't been updated in years, but it may still work with your mount.  It's free to find out!

 

Even better, PEC Tool lets you average many runs and keep the overall drift in place as well.  That's much better when doing it by hand.  Add a few runs this full moon, then a few more next, and so on.  CPWI doesn't average and removes the drift.  Once you average a few runs, save the average to a disk.  I needed CPWI training to run at least once, for some reason, for it to know there is a PEC curve (that could have changed with newer versions of CPWI, but you have already done that).  Replace the CPWI curve with the saved one you did using PEC Tool.

 

You don't need a camera with PEC Tool, but it automates the whole thing.  I used the ST4 port when training with PHD2.  I couldn't get ASCOM to work, but I had the ST4 port on my camera.  I suspect the ASCOM issue was the type of pulse I sent, but I didn't dig into it very deep because I had the ST4 port anyway.

Re-Install, but select Compatibility Mode, and use Win 7.  Installs just fine.

FWIW, you do need to have guiding running before starting the PEC training.
