OK... so I believe I have upgraded everything required for the L6.2 upgrade.? I installed the L6.2 firmware on the circuit board, updated the HC to latest, updated Gemini driver to latest, update ASCOM to latest, and flashed my servo chips with the PIC kit with the latest .hex file.
I'm running an Edge 14 on a Losmandy Titan mount, using an ONAG, so with the 0.7X reducer, my guiding F/L is 2737mm.?
After the firmware upgrades, I tried getting away with not having to re-calibrate PHD2..... no way.? So, I started re-calibrating, and the first few attempts wound up in failure.? But, I wasn't seeing movement of the star for each calibration step.? So.... I increased the number of pixels per step, saw movement, and got a pretty good calibration.? The number of steps per axis were both in the teens, expected rates for both RA and DEC were extremely close, and orthogonality was OK.... previously with L5 I had a calibration of 1.0 or less, this time I got 2.9.... the axes looked perpendicular to the naked eye, but the value was a little high.? I can probably try again and do better for orthogonality.
But, my comment is that for each time I ran a calibration, and it was probably more than 5 times, the plots of the steps were exactly on the axes.... no deviation.? Makes me kind of wonder if that relates to the encoder resolution improvement.
My real question is this:? I recently ran PEMPro with L5, and uploaded a nice PEC curve to the mount.? My thinking was that the gears have not changed with the L 6.2 upgrade..... so would the improvement in encoder resolution necessitate my re-running PEMPro, or it would not make a difference??
I do have the newest version of PEMPro that handles L 6.2.
Thanks so much.
