Re: AP V2 driver, move axis command help.

Hi Andy,

I believe that the MoveAxis rate is limited to 999x in firmware. Try using 4 degrees instead.

[Edited Message Follows]

I am having a weird issue with the AP V2 driver. Currently I use the version v5.21.01. The mount is a Mach1
GTOCP3 with the V chip and I am not using the hand controller.
This happens with both SGP and NINA. If I connect the mount and I try to nudge the mount with the direction keys
in either software the mount will not move at the requested speed. I think the software is issuing a move axis
command to the mount. I have the move rate set at 5 degrees per second.

When I push the button I see the custom tracking rate in the driver window change to 1195.7233, that is either in
Dec or RA depending on which button I pushed. However the mount will only move in the requested direction at
the sidereal speed instead of 1195.7233x.
If I move the mount using the buttons in the driver window, then it will move at the correct speed set in the driver

Since this happens with two different programs I think it may be related to the driver, unless I am missing
This has not been an issue so far but now I am unable to use the three point polar alignment routine in NINA
because the mount does not move fast enough between points. It does it at the sidereal rate and that would take

Maybe there is a setting int he driver that I am unaware of? Any help will be greatly appreciated.
Thank you!
