[Grbl_Esp32 Issue#187] Allow jogging with door open

#1 – bdring 于 2019-08-11

I can look into it. This is the type of thing I don’t like to deviate from regular Grbl on though.

Yeah that’s a bit tricky I understand. Thinking about it a $$ setting will be ideal. So for exceptional case it is possible to completely disable the door switch and run the machine open. It’s better than a physical switch, less accessible for not initiated users.

I think it is best to stay with the current Grbl rules.

Can you solve the problem with wiring?

– A key switch that overrides the door circuit?
– The door only interlocks the spindle?

Yep I can solve the problem in a hardware way. I can add a relay in parallel to the one use for spindle enable so that the door switch only work when spindle enable is turn on, so when a job is running. To override this feature (in case we need to work with the door open) I can add another switch in series with the relay.

So yeah It’s doable, just asking why “grbl” has potentially made the choice of not allowing the user to configure the door behavior so that it is possible to jog the machine with the door open.
Maybe It’s a good idea to open an issue on the grbl github. So that this project stay in line with the original grbl project.
