Wiring Stepper Drivers

[artistinfla]

I just purchased the Acorn_REV4 CNC control board. I am going to to retrofit a Chinese 6040 CNC.
I have 4 DM542T stepper drivers that I would like to use. this is a 4 axis system with a rotary axis I plan to use

I looked at the wiring schematics provided and only saw Leadshine and Gecko driver wiring diagrams
The schematic for the DM542T is available at https://www.omc-stepperonline.com/download/DM542T.pdf
It has a PUL+ PUL- DIR+ DIR- ENA+ and ENA- as does the LEADSHINE_DM_856 and 870.

Should I wire it the same? PUL- to step(x) DIR- to Dir(x) and PUL+ and DIR+ to +5V No connection to ENA+ ENA-?
I will be using 36V for the drivers.



I am just trying to make sure I read up on everything before the board arrives so I am ready for installation and testing

Thank you

Mark

Use the Leadshine schematic that shows your step & direction connections to the DB25 header

I am not using the DB25 connector. Am I wrong in assuming the DB25 port is the same as the H2 and H3 headers?

Better for you to use the DB25 connector with an inexpensive DB25 Male breakout board. Amazon sells them for about $12

The DB25 connector and H2/3 headers operate at different voltages. They are not the same. There are numerous threads discussing the differences.

Thank you. From the video it seemed that the db25 was just a compatibility thing for the gecko driver and others and that they were the same pinout


Thanks
