06-Jan-2025 Due to the large size of the main PDF (now 51.5MB) I decided to split the documents into 2 parts. I have always resisted that because I have always preferred everything in one place or document. Part1 is now a completely updated/revised/improved/expanded Basic User Guide and slow walk through of hardware choices which then leads into Part2 which covers mainly firmware and options. By the end of Part1 the user should have a good idea about what Focuser they will build, the stepper motor...
06-Jan-2025 Due to the large size of the main PDF (now 51.5MB) I decided to split the documents into 2 parts Part1 is now a completely updated/revised/improved/expanded Basic User Guide and slow walk through of hardware choices which then leads into Part2 which covers mainly firmware and options. By the end of Part1 the user should have a good idea about what Focuser they will build, the stepper motor and stepper driver, and if they will use a PCB, TZT board or Termial Adapter DIY board. Part1 now...
A continous reboot is an indication that there is an issue with the filesystem. On a boot, the chip looks for a filesystem so it can load and access settings . if the files are missing then it cant boot up so it reboots. OR the other main issue with reboots is that the wifi network it was looking for cannot be found, or the authentication credentials are wrong (IF as STATION). If you program it as ACCESSPOINT - does the reboot go away? Yes - means an issue with STATION credentials using to logon...
01-01-2026 The new focuser project that replaces this one ESP32-Dev-Module is now available. The new project supports OTA and heap more. The problem with the ESP32-DEV is that because of a huge bloat of the Arduino Core for ESP32 it meant that 4MB Flash was no longer big enough. To make the point, just create a minimal program like #include <wiff.h> void setup() {} void main() {} Select an ESP32 Dev Chip and click Verify button in Arduino IDE. The % of program space reported tells you how much the...
01-01-2026 The new focuser project that replaces this one ESP32-Dev-Module is now available. The new project supports OTA and heap more. The problem with the ESP32-DEV is that because of a huge bloat of the Arduino Core for ESP32 it meant that 4MB Flash was no longer big enough. The S3 version is much better, with 16MB Flash, room for OTA and heaps more bells and whistles. Latest Arduino IDE 2.3.7 and Latest Espressif ESP32 Core 3.3.5 supported. . You cannot use the existing PCB for ESP32-Dev on...
Hi Hello, I had to update the firmware of an old focuser that had an IR remote module so that it would work with the latest version of the Windows app. I therefore uploaded it with firmware 338. The focuser works correctly, but as a result, I no longer have the IR remote function. The option does not seem to be available in config.h. Is there any way to get it back? Thank you, Best regards, Didier Papavoine. You forgot to mention what the board type is. Posting your config.h file would help. As well...

29-12-2025 VERY IMPORTANT INFORMATION Latest User Guide PDF is myESP32S3_321_15. Download it first because all references to the PDF apply to v321_15 only. ENVIRONMENT The compiler environment you need to have is Arduino IDE 2.3.7 Expressif ESP32 Core 3.3.5 https://github.com/espressif/arduino-esp32 If you do NOT have this environment now, then upgrade BEFORE attempting to do anything with the firmware. ARDUINO LIBRARIES The project libraries are found in the folder libraryfiles when the firmware...
