Try as I might seems like the signal strength isn't there.  plenty of 5 volt power and set only the 1st port to power also the second.  Could this be a stepper driver problem?  Ordered a BOB today, my old C-10 stopped after adding a 4th axis.  Thought it could be a resonance problem but more likely not.  Ordered gecko steppers to replace the Keling K5056-D and the K-8070-D.  Also thought it could be a recent recent windows 10 upgrade.  All lights are correct.  The ESS pings. 
Any thoughts?
