Hello,

I bought the Onstep Blue Pill PCB.

 

What firmware version do You recommend to download?

https://github.com/h...nStepX/releases ??? Or some other ?

 

If the one I provided, where to download the firmware for Wemos Mini? I found, that in older versions there was a "addons/Wifi" directory in the .zip file, and there was software for Wemos D1 Mini. I do not see such a file/directory with the Wemos software in the files downloaded from the link.

 

I found page: https://onstep.group.../main/wiki/3915

Firmware for Onstep Blue Pill (and not OnStepX), has folder "addons/Wifi". Where is firmware for Wemos D1 Mini for OnstepX?

unfortunately you bought an obsolete board. OnstepX won't run smoothly on the bluepill because the microcontroller has too limited flash memory (128K).

You would rather upload Onstep (4.24 is the last release if I'm not wrong).

I have built 3 bluepill boards and even if onstepX won't run on them  they are great. Just stick to OnStep.

Refer to the onstep forum for further questons. It is a very active one. Howard Dutton, OnStep author, and many other members are always ready to help.

If you really want OnStepX my suggestion is to check the Fysetc E4 board.

The Fysetc E4 board is very easy to set up. You can even load the firmware from a web browser with basically just a click.

OK, I've assembled my board. I had already purchased the elements.

 

Downloaded OnStep-release-4.24

 

Changes in the Config.h file, change anything else?:

#define PINMAP                        STM32Blue
#define BUZZER                        ON
#define BUZZER_STATE_DEFAULT          ON
#define TIME_LOCATION_SOURCE          DS3231

#define AXIS1_STEPS_PER_DEGREE        28728.9   (from configurator)
#define AXIS1_STEPS_PER_WORMROT       25600     (from configurator)
#define AXIS1_DRIVER_MODEL            LV8729
#define AXIS1_DRIVER_MICROSTEPS       128
#define AXIS1_DRIVER_MICROSTEPS_GOTO  4         (is it good???)

#define AXIS2_STEPS_PER_DEGREE        28728.9   (axis 2 it is copy of axis 1)
#define AXIS2_DRIVER_MODEL            LV8729
#define AXIS2_DRIVER_MICROSTEPS       128
#define AXIS2_DRIVER_MICROSTEPS_GOTO  4

You can use OnstepX following this tutorial https://onstep.group...main/wiki/32784

------

If you want more performance and future proof buy RobotDyn STM32F303CC (Same tutorial talks about it)

or with a little modification buy a more powerful GD32 Core. GD32F303CCT6 information is here https://onstep.group...turns/102770806 (look for George comment about not connecting 5V pin)

change anything else?

Yes,

I you end buying GD32F303CCT6 (a.k.a. BluePill Plus). I have the solution here https://onstep.group...epill/110449123
