Hello everyone, I really did not want to write this but I am really at my wits end with the system that I purchased from kelling - I purchased the 1200oz nema 34 cnc 72v system, from the get go it has been nothing but problems, the first thing that went wrong was that the power supply never made it to me and I had to contact kelling to send me a replacement unit- okay I can deal with that,
I was finishing the machine that all these parts were going on. I then started to review the wiring schematic- these things are a way below acceptable -after trying to find a phone number for kelling and few emails that provided little help I am ready to send this package back.
the customer support for this product really needs help.
I was planning originally to use these on a few other retrofits but I am reconsidering that option.
