Agree fully with beanflying :
HOPE THIS ADDS PERSPECTIVE:
Placed this order with them 2 days ago
Upgrading controller existing K2cnc 4' x 8" CNC router
Poor quality factory wiring, connectors , controller and switches ,crudely implemented Power supply. Minimal documentation
Will be adding VFD & spindle later as well as numerous as yet speculative functions
Upgrading to Ethernet interface and a well documented modular expandable upgrade path is the goal
Should note that machine is otherwise well and cleanly built around 2009, beyond initial setup up was barely played with and built with industry standard components exclusive of the toy like controller and power supply .
Will be reused:
4 Gecko G320 DC servo drives
4 CUI devices AMT103-V encoders
Will at least initially use their recommended low cost software UCCNC
Note that this invoice does not include the numerous required RJ45 terminated cables , other wiring , connectors , power supplies etc .
I was very impressed with the rapid response and quality of the pre purchase technical support . However I was provided with a full parts list by them that was comically inappropriate , inaccurate by omissions , quantities and even some pricing .

Drawing supplied by CN4PC is almost identical to the generic upgrade configuration I had decided upon , exceptions will probably be confined to the fan and power supplies .
This is obviously not the most economical solution available
