Slew problem


wa1vta01452
 

I have posted about this before. The DEC is running much slower than RA in slew mode using my laptop with ascom. I had changed EVERYTHING in the hardware twice now with no success. This morning I set up for bluetooth with the Android app and lo and behold, the DEC slewed just fine this time. I wonder if someone can take a look at my config.h to see where there may be an issue. I left off all below axis 2 since I am not using anything below that. The mount is a G11 and I am set up with TMC2130s with the 4 soldered jumpers.
Thanks,
Tom
