DDCS V3.1 & DD8727T4V1

Patmaz

Hello.

How to connect a stepper motor driver DD8727T4V1 to a controller DDCS V3.1. The driver has a common + input for all PULL and DIR control signals. If you combine all the positive motor control ports of the controller (as in the picture), the motors either do not spin, or several motors are running simultaneously. The driver is OK. Tested with mach3 stb4100 usb board before and after connecting to DDCS V3.1.


Thanks

Hi.

You can not connect DDCS and DD8727T4V1 directly. But you can connect it with additional electronics. How to do this? I'm not sure because manual for DD8727T4V1 is not well prepare, have lack of information and is not perfect. I don't have this electronic. But i try to show how it can be. See my schema bellow.

You can see and test more by using your hand and multimeter.

Generally I not recommend using DD8727T4V1 with DDCS. If you have some more space in control cabinet buy 4 pcs TB6560 Stepper Driver. It's not much more cost, eg. https://pl.aliexpress.com/item/4000458970475.html but then you have not any problems in work.
