Jyers firmware question. So I have jyers installed now, and did the screen firmware as well. Now I have a Cr touch that I am about to install, I understand that I need to do the firmware for the machine, but what about the screen? Does that also need to be done again cause of the bed leaving probe, or is it the same with or with out the probe?.
