PHD does not command RA axis. Only DEC axis is working.
« on: March 07, 2016, 13:24:24 »

Hello,

I hope somebody can give me a hand on this. I have a Skywatcher EQ5 mount and am looking into autoguide.

I have already the dual axis motors, AstroEQ and all the cables, guide cam, etc. Also, I successfully managed to install ASCOM drivers and it is working perfectly. I can move the motors on both RA and DEC axis using the EQMOD controls. The sidereal tracking works good as well.

Now coming to the PHD Guiding 1.14.2 (or PHD2) is where I have the problem. It can identify succesfully my camera and mount, seems to be all normal. However the RA axis is not receiving commands from PHD. The manual output works for North/South - DEC axis - but it doesn't work on EAST/WEST - RA axis. When the PHD calls out the EQMOD, I can manage both axis normally from there. But from the PHD, only the DEC axis.

Then I got problems calibrating since the east/west steps from PHD do not work.

Any help is appreciated.

Thanks,

Marcos
