hello folks so i have a issue maybe it can be solved i have several of these probotix controllers on these mini 4 axis mills. they are in a workshop for teaching students how to set up program and run cnc machines. now im no stranger to cnc controllers i have my own set up at home. now the controllers work and move the machine but on start up of the cnc usb software it brings up the serial number and serial code all this and asks for a registration code. is there anyway i can get these codes as i have i 6 of these machines. i do not know when the school purchased these or what deal was made. but the students had been told that theses machines are broken and wont even turn on which is where i came into this problem. my friend is the teacher for this school hes fairly knowledgeable about most things shop but nothing machining for cnc related and well you know how the rest went. im including pics of the breakout boards from 2 different boxes to help maybe shed some light on this for a possible fix. if my friends school credentials are needed ill have him contact you directly we really just want to get this going to teach the kids something new and interesting... thank you for your time..
