YuanKanJu Ethernet Smooth Stepper with C25

I purchased the ESS Smooth Stepper CNC control board to replace a similar (competitors) board to control my CNC router. I was having ongoing connection issues where the board would loose communication with the PC. Very frustrating in the middle of a job with a 15 hour run time. So far I am quite happy with the controller, a few problems with getting the ethernet to communicate initially, but about what I expected. Had a question that I posted to the forum and received a prompt answer from Warp9.

This is the third unit I have purchased, and they all have performed without problem. Documentation is complete, but does take some searching to find some of the details, such as register numbers. Overall very satisfied with the unit.
