[Grbl_Esp32 Issue#47] Hard limit causes crash when using SD Card About GRBL HAL

Issue #47 | 状态: 进行中 | 作者: gflaser-au | 创建时间: 2018-10-28

Hard limit ISR calls mc_reset, which calls file close if streaming gcode from an sd card file.
close attempts to take a lock which causes the crash (can’t take a lock in interrupt context).

Unsure how best to attack this, but it would be nice to gracefully recover so a software reset could be issued to bring the machine back to operating state once the hard limit switch has been cleared.

Currently requires a hard reset / power cycle to recover.

I will think about this. I agree you should be able to recover from the keyboard.
