Last night running a program my partner realized the control which is a heidenhain tnc 151 was getting drenched by coolant ( kool mist flood water based) and it didn't seem to like it much now just after drying out with compressed air and contact cleaner it will home itself go over the axis points but no buttons work to put it in different modes. Were having some faith that it just needs to completely dry (overnight). Has anyone else experienced something similar? if it doesn't come back to life does anyone have one for purchase?
