Good morning,

I made the FocuserPro and it works relatively well.

I found some problems with my motor. The motor I used is NEMA17-PG27.

The problem was due to so many vibrations and sounds when the motor moves
and I couldn’t solve them.

I have decided to insist and build Myfocuserpro2.

My idea is to use TMC2209 or TMC2225, preferable the TMC2225 for using then
end stop detection without sensor.

In my 3dprinter I am using TMC2209 and works very well without any problems
and without sounds and vibrations and it can solve my motor problems.

My doubts came when I try to select the PCB, in the file
myfocuserpro2-designs.pdf I can see:

*TMC2209 *

*PCB *

TB6612FNG-Rev06-Gerbers.zip

*Driver Chip *

TMC2209 BigTree Tech

*Firmware *

myFP2_TMC2209SG-312

*Options *

TP, OLED/LCD, HPSW, SPD, PB

*TMC2225 *

*PCB *

TB6612FNG-Rev06-Gerbers.zip

*Driver Chip *

TMC2225 BigTree Tech

*Firmware *

myFP2_TB6612FNG_312

*Options *

TP, OLED/LCD, HPSW, SPD, PB

But in the Geber Files folder I can see the file
“myFP2-TMC2225_TMC2209-Rev06-Gerbers.zip”

What of the two files I need to use “TB6612FNG-Rev06-Gerbers.zip” or
“myFP2-TMC2225_TMC2209-Rev06-Gerbers.zip”?

I suppose that is a mistake in the pdf file and is the
“myFP2-TMC2225_TMC2209-Rev06-Gerbers.zip”

Another question is if it is possible to use blue tooth or IR with these
drivers. I have read in the forum that can be some problems.

Thanks for that great project.

Regards,
