I will upload PCB new for RE now.
PCB now here only for OLED with Rotary Encoder, DRV8825 HW203 layout https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/DRIVER%20BOARDS/BOARD%20PCB%20DRV8825%20HW203%20OLED%20RE/
OLED connect to I2C connector J2
Home position switch connect to JP15
Rotary Encoder connect to JP17
Push buttons connect to JP8 and JP9 and if using push buttons short JP10
LED's connect to JP2 and JP1 - if using prewired 5V LED then short JP5 and JP6
12V Power on off switch to JP7
Connect 12VDC to JP4
12V Power LED RED connect to JP13 - if using prewired LED then short JP14
Buzzer connect to JP3
Power On Reset Switch connect to JP12
Temp probe DS18B20 connect to SV2
JP16 wired to RS232 connector
I had to make new DRV8825 part but I think all is good now.
Cheers

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Just noticed problem - should leave Push Buttons off board. Not a good idea to have push buttons when using rotary enocder. So I will make change to board and upload version with no push buttons.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
What size drill bit do you recommend for drilling the holes in the board?
Hi Mark
I recommend 0.8mm for all holes,and 1mm for 10A10 diode, LM7808 and header pins.
Best wishes for your build.
Cheers
Robert
Thanks
Which PCB version I can/must use for FULL, DRV8825, Rotaryencoder, OLED, Homeswitch, Tempprob?
You can make stripboard
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/DRIVER%20BOARDS/BOARD%20DRV8825_HW203/BOARD%20DRV8825_HW203_RE/
and use this firmware
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/CODE%20ARDUINO/DRV8825_HW203_F_OLED_RE/
If need PCB, then none now with that combination. Only stripboard
If want PCB will need to design new board, maybe few days.

Robert

Firmware is same as link before but only for this new RE PCB.
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/CODE%20ARDUINO/DRV8825_HW203_F_OLED_RE/
Could use this new RE PCB board without RE with this firmware - leave RE components off PCB - R11, R12, R13, R14, R15, C5, C6, then use this firmware.
Focuserv250_DRV8825_HW203_F_OLED.ino
Only FULL option supported.
