My son ( computer knowledge ) and I have been trouble shooting most of the day.1. With no USB or Ethernet cables attaches Laser head travels normal and laser will pulse correctly.2.With Ethernet Cable attached Laser Head travels correctly and pulses but can not connect to either RD Works or Lightburn.3. Ethernet Cable disconnected and USB plugged in laser head more or less grinds in travel and laser will not fire.4. Substituted the USB cable and same results as above, subed the ethernet cable and same results above on 2 computers.5, Do you think could be bad RDC 6442S-s controller?
Any ideas what is wrong or what next to try?
