Hello everybody,
I am a french user of the syil SX3 cnc kit and as some of you I have troubles with stepper drivers and spindle upgrade board.
the syil's documentation is quite poor on the electronics part of their kit.
This post only to point out ( specially to Greg - "greolt" ) that a very good source of informations on the web site
http://koeiners.nl is no more available (unfortunately the site is not active since months)
Best regards.
