PHD2 parameters with heavy load

Post by Bretoc »

Hello
I am new to the forum, and I am having issues with making my NXY work with PHD2.
First, my gear is, apart from the mount, an RC250@f8, a 571C camera (yes it is over sampling by a lot!). The total load is about 20kg, so I added a 5kg CW, positioned roughly at 2/3 of the end of the bar.
When switched off, there is no sign of dec drift, so I guess it is properly balanced on the DEC axis.
Last night, I simply could not get PHD2 to guide (huge peaks on both axis, then PHD2 stopped).
Which parameters would you recommend for such a heavy load?
My guide cam pixels are 2.9 microns, the guide scope focal length is 260mm.
Thanks in advance for your support

Same frustrating problem here, with a much modest load, RC8 and counter weight.
Polar alignment has been a breeze, with the polemaster.
´o way to manage to get phd2 to work, with severe problems of orthogonality reported by phd
Very frustrating.

Did you see any issues with backlash being reported yet measured backlash looks good , I've just posted a new thread today in this group with details.
