Stepper motor module not reporting settings

[bsculley]

The stepper motor module provides an I2C interface to GRBL. The '$$' command is supposed to return all the settings, but all I am getting is:

$$

$0mnoing seek, mm/min)
$21=100 (homing debounce, msec)
$22=1.000 (homing pull-off, mm)
ok

This does not include the steps/mm ($100-$102) settings without which the module is useless.

Maybe I have a module with downlevel firmware, but I have no idea how to upgrade it, or even if it's possible. Any help will be appreciated.

step/mm not $100-$102, try test this https://github.com/m5stack/stepmotor_module/blob/master/Firmware%20for%20stepmotor%20module/GRBL-Arduino-Library/report.cpp#L146

Ok, I see from the code that X, Y and Z steps/mm are $0, $1 and $2, but when I send $$, I am not getting the list indicated in the code. Only this: $$ $0mnoing seek, mm/min) $21=100 (homing debounce, msec) $22=1.000 (homing pull-off, mm) ok Apparently the code running on the device is not the same as what is shown in the link. Is there a way to reflash the stepper control module?

Tx buf not enough, so some data is lost.

Ok, thanks. But the code referenced is a part of GRBL, not part of the Arduino sketch. How can I apply any changes to the stepper controller module? Is there a procedure to reflash the stepper controller?

sorry, reflash step controllers is not yet supported

[bsculley]

So how can I make it work?

Hello, what changes do you want to apply? if you want to change the steps you can solder the jumpers on the board to change the step modes (there are 3 different modes)
