I just tested the myFocuserPro2 with the Jasem fix. The joystick number of steps follows perfectly the relative position setting and, cherry on the cake, the backlash is taken into account. It seems to me that it was not the case with the precedent solution.
Great thanks to Alan and Jasem
I appreciate your efforts to improve the joystick operation.
My feeling is that it should be nice if effectively you could use the set relative step. In that way each user could set a number of steps according to the gear reduction of his focuser system.
But maybe there is some drawbacks to implement this solution...
Thanks Alan for your reply.
I do not realize what that represents in terms of coding but the ideal would be to have something like in ekos/focuser, that is buttons with the possibility of choosing the number of steps.
This feature is not essential but could be convenient when observing at the eyepiece.
First, many thanks for the great job you are doing by developing this driver.
I am presently doing tests of a myFocuserPro2 connected to a RPI3B+/stellarmate 1.4.4 as server, the client being Kstars/Ekos on a laptop running Linux Mint (~ Ubuntu). The results are very good. I just would like to report a strange behaviour when playing with the joystick.
As I already use a joystick to manually move my HEQ5Pro mount, I thought to dedicate 3 of the free remaining buttons to also control the focuser. The buttons (in, out and abort) react reliably but the amount of steps when I push them, in or out, is "huge" and not constant, variyng roughly between 60 and 80 (~ 2 times my CFZ !). As it now stands, the joystick feature appears to be not really usable.
If I change from full step to 1/4 step mode, the number of step is multiplied by 4, which makes me to suspect the command sent is a time pulse and not a number of steps. Am I right ?
I didn't find any place in the INDI driver menus or Ekos/focus where to manage this parameter. Maybe the joystick support is a part of the driver development which is not yet finalised.
Thanks for bringing me some light.
It seems to me this behaviour is frequent in other drivers and cannot be regarded as a bug nor an annoyance. In my opinion, there is no clear interest having this box filled out, as the value is already set in the left one at the connection.
Great thanks to the developer(s). I hope this driver will be included soon in the stable indi library.
Sorry, I did'nt pay attention to the Indi release numbering.
Ok Jasem, thanks for your feedback. I was misled by the indi web page regarding this focuser that suggests that the driver is available.
This is my first post.
I read carefully most of the threads on this forum since few months. In fact since I installed a RPi3b+, running Stellarmate as server for my astronomy equipment. I learn a lot and most of the time, I find answers to my questions. thanks to all for that.
I just received a "myFocuser Pro2" from Robert Brown in New Zeeland and I would like to test it, first via Kstars/Indi device manager and then, directly via ekos.
My problem is that I do not find the driver in the list of the focusers, even after having updated Indi... Probably I missed something
Thanks for your help,

About meAmateur astronomer since long time, I am now retired and I start again observing after a few years interruption.
My telescope is a Skywatcher 200/100 installed on an HEQ5 mount. Recently I upgraded this mount with the Synscan GOTO kit and I finally replaced the remaining gears by a synchronous belt/pulley system (Rowan kit). I am pretty happy with that combination, not perfect for sure but greatly improved by the two kits.
In parallel, I installed on the mount a Rpi3+ operated by the stellarmate OS. All of it is controlled by a Linux Mint PC.
