Change Trigger State of Endstop

Hi,

I'm using nanodlp shield v2.1 with a optical endstop switch. How can change triggered state of endstop? Now the endstop works inverted....
Thanks

Re: Change Trigger State of Endstop

You can change it using Default state on the machine settings page.

Shanin, can you tell more specified tip for this like with picture, because it seems pretty often problem, or is there already somekind of "usermanual" for setupping?

The same problem with NanoDLP controller board.
My Z_min endstop triggered normally and open if I place an object in the lightbeam of the endstop.
So how can I make it to work opposite?

Default NanoDLP controller board support NPN and not PNP, using PNP require firmware change.

Yes exactly it's all clear, but how to change NO to NC in the firmware?
How to change the line
Z_MIN_ENDSTOP_INVERTING = true

That's my question.

P.S. On CNC machines(Mach3) it's simple to invert. But I don't get how it work's here and why it's so complicated.

I can provide hex file to flash it but to flash it you will need to both make sure driver being recognized on your os and use arduino tools or avrdude.

This board with simple atmega 2560 so it's no problem to flash it.
But how it's possible to invert z_min in hex file?
As I understand that I need configuration.h file to adjust this or not?

he is making the modification for you and sending the compiled hex file that you just need to flash. I find this process cumbersome, all we need is the source code. Marlin is under GNU GPL license, so he is actually required to release the code.

Marlin source code is intact you can use it, if you do not need help to compile it.

Re: Change Trigger State of Endstop

can you share your configuration at least? and pin config I guess?

Okay! It's great to get hex file with inverted z_min. For now it's all I need to finish my printer.

Re: Change Trigger State of Endstop

And this thread is dead? No miracle ? hex file with inverted z_min, configuration.h file, pin config or something ?

the board is basically a standard ramps with the D8 pin set to -1.
