using with esp8266

[assegid]

Can someone please provide simplified instructions on how to use this library with the esp8266 board on a Mac and Arduino IDE? Will it work at all? I think I read somewhere that boards other than AVRs can only be used with windows?

I there.
This is not a library (although it might be possible to convert it into one).

I recommend using VSCode and PlatformIO extension.

But you can build the code using Arduino.
Follow these instructions and install the ESP8266 boards in the board manager.
Select the LOLIN WEMOS D1 board
Open the uCNC.ino sketch
To use the configuration for the Wemos D1 board modify the BOARD line to:

#ifndef BOARD
#define BOARD "esp8266/boardmap_wemos_d1.h"
#endif

Also comment the line in build_opt.h or simply delete that file (this is a file specific for STM32 builds but seems to cause a build error under Arduino)

You should be able to get the code compiled like this

I made the changes you suggested and the code did compile in Arduino. But where can I see the pin assignments for the Step and Dir lines? I assumed that assignment can be made using the boardmap_overrides.h file that can be generated using the web tool. But when I did that compilation fails with the error on the #include "boardmap_reset.h" line. Is it ok to just comment out that line?

Also note that the default pins for that board are defined in this file

[Paciente8159]

Did you add the files included in the zip to the project?
That file does not exist in the default project. It's generated by the web builder and must be added.

The Flash size difference should explain the odd settings values.
This latest version of µCNC prevents any motion or action with invalid settings loaded that is why it was always in locked/Alarm mode

i think that difference is because I am using the D1 mini pro which has 16MB flash. The only way to change that is by selecting D1 R2 mini, which I did just for testing purposes. I was actually surprised that the IDE allowed me to upload the program by selecting D1 R2 instead of D1 pro, but it did. Nevertheless, the result was the same; stuck in Alarm state.

Then you can choose your board again.
Try uncommenting this setting

uCNC/uCNC/cnc_config.h

Line 128 in 785c014

// #define RAM_ONLY_SETTINGS

Remeber you will loose all your settings each power up/down

[assegid]

That did not work, but uncommenting lines 388, 574, 577 and 580 did it. Thank you so much for your help!!!

[Paciente8159]

Ok. I bet line 574 did the trick.
By the way did you changed this line?

uCNC/uCNC/cnc_config.h

Line 55 in 785c014

#define BOARD "avr/boardmap_uno.h"

If not you are probably loading arduino uno pinout under your overrides.
Later I'll check if that is the problem
