China CNC 6040 - Setup

[Gary]

Hi All,

I have just purchased and set up my China CNC 6040.  Although Mach3 reports the X, Y and Z data is changing, none of the motors move.  They are all correctly locked up when the power is turned on.  I have tried a couple of old XP based PC's with standard parallel/printer ports so I think I am transmitting the data OK.  I took the case off and can only assume that the yoocnc-450JKB (breakout) board has failed.  Is there a simple way to test the output of my parallel/printer ports and generate test inputs to the 450JKB to check the motors move?

Cheers

Gary

hmm, the 6040....

Is it this one:

First the supplied controller is a death trap - the 100V for the milling motor is derived directly from the mains and therefore is potentially lethal.
My one had off centre couplers which caused the stepper motors to jam - they would move, but skip frequently and when I loosened the mounting bolts for the stepper motors the motors moved around - fortunately new couplers are readily available.
while I did run the original controller for a while, fortunately it blew itself up before it killed me fairly early.

so you need to get a new controller anyway, and you may need to change the stepper motor couplers as well
