Hello,
I have a problem with my WMD30/BF30 RPM display, in which it stopped showing the RPM values. I have checked the circuit board "cesx 1101-28", which is common in many versions of machines i.e. G0704 and all small Chinese mills.I cannot understand where is this problem coming from. I am also attaching a small video showing how it all started. The machine is still working as before but without any RPM display. Can anybody help or have had this issue?
