Hey All.

I have a Syil X4. It is a 2013 model and has never made a single chip! The spindle control has been blown out since it was new. When I finally got around to fixing it, Syil didn't sell parts anymore. I tried having the board rebuilt. No Joy.

Stephen at DMM set me up with a DYN4 Servo Controller and a servo motor for the spindle drive. I bench tested the DMM hardware. It all works. Then I installed in the Syil Mill. I can run the spindle using the DMM testing software, so everything is powered up correctly.

I made the connection to the Syil Controller per Stephen's directions, which are as follows:

So the connection is:
Controller P/A into DYN4 Pin 13 AIN+
Controller Gnd into DYN4 Pin25 AIN-
Controller Gnd into DYN4 Pin1 Gnd
Controller DIR to DYN4 DIR+ Pin 22
Controller Gnd to DYN4 DIR- Pin 10
The analog from the controller will control the spindle speed, the DIR output from controller will control the spindle rotation direction.


Pics attached of the ribbon cable at both ends.

The result is that I cannot control the spindle through the Mach 3 software. I can control all 3 axes on the mill, so I do know that Mach3 is talking to the mill. I can't help but think there is some settings in Mach 3 that aren't set up correctly.

Can any of you Mach maniacs guide me through a list of settings, or some such?

Thanking you in advance for any help,

Best,

Chris E.
