Hello everyone ! I’m sorry to have to ask for that… I had made my Mpcnc, my board is an Rambo 1.3 and flash with this firmware https://github.com/Allted/Marlin/tree/MPCNC_Rambo_T8_16T_LCD/Marlin
I had buy and 3dtouch (similar and not perfect 3dtouch copy ^^ ) but I had a big problem…
I had correctly ( I think ) connect it to my board but it’s doesn’t work… anyone had an idea why ? ( I think the problem is from configuration.h or configuration_adv.h but i’m a begginer and french,I don’t understand all ^^ )
Thank you very mush is you can help me !!
Not sure if that screen works with rambo.
the screen is not a problem… But Z min is doesn’t work 
Is the 3d touch like the bltouch? Marlin needs to be configured to send the servo output to control it. Pretty much any instructions for configuring marlin for a bltouch should work. You don’t need/want the bed levelling parts though.
thank you for your help ! I fixed the problem,Bl touch was connected to the wrong pin on rambo,sorry !
