I'm fairly new to AP and INDI as well with just a few questions...
How does PEC training in EQMOD work? I've tried to enable training but without any result. Also, will it help smooth out guiding? Guiding error is averaging 0.5" per night.
Also, is there a how-to for setting horizon limits correctly?
EDIT: Looks like Horizon management is not documented there. Well, hopefully someone who used this functionality can explain it in detail and I'll update the documentation accordingly.
Hi,PEC training works the same way as with the handcontroller. Guide on a star, engage PEC training and the firmware will wait for the mount pass the worm indexer and then records the resulting speeds in the EEPROM of the motor microcontroller. When it has finished (worm indexer) it toggles a status bit and you can see in the INDI Control panel the status of PEC training becoming green (whereas it remains busy/yellow while training). I've never tried myself however.For horizon limit just slew to the points along the horizon you want to set and hit the Add current button. The order of points is significant as Horizon uses a linear approximation between them. When you have finished hit the Write File button (saved in ~/.indi/HorizonData.txt which you can manually edit also).
I have never seen PEC training in INDI EQMOD either. I just assumed it was either never implemented or wasn't possible. It certainly would be nice if I could do that, and maybe use PecPrep with it.
My HEQ5 Pro should support it.
PEC/PEC training is enabled in INDI EQMod for mounts which supports it, EQ8, AZEQ5/6, EQ6R too apparently. It is a motor controller firmware feature, the INDI driver just sends the corresponding commands to start/stop PEC/PEC training and don't then bother about it. It makes me think that this firmware PEC+guiding may not be a good idea as the firmware changes the motor speed unconditionnally, so some guide commands may be lost. There may have been some discussions already here.
