I want my touch plate to work with my Proxon MF70 CNC machine, which is connected to rhe GRBL arduino shield an operated frem Estlcam.
it works well, but i cannot get the touch plate function to work from Estlcam.
i connect the two touch plare wires to GND abd SEL pins on the GRBL board, but it is like Estlcam does not "see" this input.
Anyone knows how i can set this up in Estlcam, i have bere in the section where i can configure inputs, also for "prope" which is what Estlcam calle the touch plate function, but i do not understand how to adress the specific SEL pin on the GRBL board, from this setup section.
can anybody help?
