Can you give me more information aabout the system: wiring between stepper motor and driver controler, and with arduino pins and webcam (schematix picture if possible) and how start and stop the system.
However when using OpenPHD2 2.1.3a I was getting errors "ascom driver failed checking slewing" every time a guide pulse is sent to the mount?!?!? and I have to click the OK button on the error box that pops up.
Apparently a fix was added in OpenPHD 2.3.0 which allows PHD2 to ignore this type of error. When I upgraded to 2.3.1 the error still pops up but I now can guide. My challenge now is getting PEC working.
