Ive been using an earlier version of MyFP2 with no problems for the last 3 years then last night i couldnt move the focuser beyond 10,000, always been able to move to 20k. Cant see anywhere to change this or why its happened. I got by changing the position to 5k to allow autofocus to work.
Firmware version myfp2L293Dmini, 300
Thanks!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
What you can do is the following
Start Arduino IDE. Does not matter what file is loaded.
Connect controller via USB
Open Serial port, set speed to 9600.
(assuming stepper motor not connected)
All commands start with colon amd end with #
First change maxsteps to a large value
In comms protocol pdf the command to do this 07
Type the command
:0725000#
press enter
to check use this command
:08#
which show reply with
M25000#
next set focuser position without moving the motor, to 20000
:3120000#
and to see the new position type
:00#
and the reply should be
P20000#
Now set the position where you want it be, and then end with
:48#
to save this config to eeprom in controller
Any issues let me know.
Regards

Most times - when position cannot be changed is becaise the new position is either greater than maxStep.
