grbl32's Issues

Expansion board for grbl32

Dear friend. How can I order an expansion board for grbl32 or for ordering in JLCPCB?
Thanks.

How do we compile for an already existing board? With all the pins mixed up.

Just to get your attention.

If found a really cheap Bluetooth enabled laser engraver.
I got mine for 115 euro inc shipping.
I'm currently sorting out the PCB.
I've got some STM32F10x info on my:

Directory case mismatch.

Git clone of the repo seems to name the directory "Src"
Makefile defines it as "src"
On case sensitive filesystems this causes the build to fail.

Step pulse width not correct

Measuring the step pulse width with a logic analyzer, pulse width varies from 2.5 to 5.8 μs instead of the 10 μs specified in defaults.h

different speeds between X and other axis

Hi,

i have an issue where the X-axis can achieve almost 100khz on the step pin, but all other axis a max of 4khz. if i combine the x-axis with any other then the movement is also 4khz.

Is there any config or codechange that could affect this?
