Finally, after some changes the final I put my final assembly in the
picture and video.
For me the more complex problem has been the motor vibration.
I have put same insulator in both sides of the motor and the base is
insulated by some rubber rings.
Although with this, the noise is audible. I hope not to have vibration in
the focuser. In my previously version the ocular vibrates in high speed. I
will tell you then I test it in a real session. Now I hope that the belt
insulates the transmission of vibration.
That I have noticed is that when moving the motor outside of the telescope
tube, the noise is really low. The tube is acting as a noise amplifying.
Hi Julio
Looks good. In real operation vibration should not be an issue.
here is why,
When autofocusing, the focuser is moving a short distance, not whole revolutions. Then stopped. Then an image is taken. Then the FWHM is caluclated, the next position determined and this sequence is repeated till best focus is achieved.
So the focuser is actually not moving when an image is taken.
In addition, myfocuserpro2 has a feature called DelayAfterMove, which can insert a time delay to allow for the motor to fully settle after a move. The manual contains more information on this.
Thanks for the photos and video. It is looking good.
Regards
Robert

I am thinking about passing to myfocuserpro2 because it has interesting features.
I tried to do some weeks ago but I saw that this new version doesn’t permit to have at the same time IR and Bluetooth (I tried with the firmware myFP2_DRV8825HW203_290).
When I take pictures I use the focuser connected to my PC by Bluetooth, but in visual sessions I don’t use the PC for focusing and I use the IR remote control to change the focus position.
Another option is to use the mobile phone, but the backlight (at minimum) is too strong and blind me every time I use.
In the myfocuserpro I can have at the same time Buttons+IR+Bluetooth. Is this possible in myfocuserpro2?

ESp32 is complete new hardware, so no not possible.
I had just checked boards in myfocuserpro2
// DRV8825HW203_FIRBT https://aisler.net/p/UGHLNFJC for infra red controller
This should be able to do bluetooth and infrared at same time.
I need make adjustment in firmware.
If you have this board I can send you new firmware to try

Yes, now I have this firmware and I and using IR+BT+Buttons without problems.
But for ussing the new functions of myfocuserpro2 I need to install the FP2_DRV8825HW203_290 firmware. Is this correct?
With the firmware Focuserv176_DRV8825_HW203_IR.ino, I installed the windows aplication for myfocuserpro2 and it did't work.

Don't worry about that.
All seems to work ok and Now I prefer to have all the options.
If in the future I need the new function I will think to change to myFocuserPro2 firmware only with bluetooth or (IR+USB cable for the PC).

You cannot use IR and BT together. Because they use same hardware pins on Arduino. This is function of 3rd party libraries being used.
However, esp32 version of myfocuser pro can use infrared and also wifi. It can also do bluetooth and IR at the same time.
https://sourceforge.net/projects/myfocuserpro2-esp32/
It is in beta test now. here is video

Thanks Robert,
For the esp32 version, Can I use the hardware I have but only programing with the new firmware?

ESp32 is complete new hardware, so no not possible.

What board do you have? let me know and I will look into it.
Thanks Robert,
I have the option: PCB REV4 DRV8825-HW203.
I attach the PCB picture.

In myfocuserpro
This board should be able to do both IR and BT at same time.

myFocuserPro - v1xxx firmware, Windows App v1xxx, ASCOMDriver 1xx
not compatible with myFocuserPro2
myFocuserPro2 - v2xx firmware, Windows App v2xxx, ASCOMDriver 2xx
You cannot run firmware v1xx using v2xx software
If you want to use v2xx software you must update firmware to v2xx
