[Grbl_Esp32 Issue#615] Endstop About GRBL HAL

Issue #615 | 状态: 已关闭 | 作者: topogigio | 创建时间: 2020-09-26

Hi,
thanks for your great job.
I’m trying to test endstop, I double check pin assignment and hw change status on esp32 pin.
I don’t thing that’s an issue, but for me doesn’t work, what I miss…
How can I configure separate enable motor for each axis?

My machine conf file at the end.
Regards
Andrea

You can map up to 2 switch input per axis like…

“C++ #define XLIMITPIN GPIONUM17 #define X2LIMITPIN GPIONUM2“

They are linked together in firmware. You will only see the X axis switch triggered in the status regardless of which switch was triggered. It is the same as wiring 2 switches to the same input assuming you wire them correctly for N.O. and N.C modes.

Thanks for prompt reply, Pn:X and other axes are showed when I pressed each endstop.
Btw, notting happen when motor spin and I press correspondent endstop.

Endstops will only stop motion during homing and when used as hard limits.
