I see, i just wired it by the standard wiring diagram but i can see where the db25 would be benificial. I am currently using the acorn power supply 5v terminal and sharing it between the drives but the db25 will supply its own 5v. I will order one and do it that way. Are there any other benifits? Thanks for the schematic Marty, I was not understanding why i needed the db25.

Oops , misread the schematic. It doesnt supply 5v at the db25 and still uses the acorn power supply, so what would be the benifit? I will still have screw terminals on the db25?

Can you PLEASE post a picture or make and model of your drives? And or a link to its manual so we can better make a suggestion.
I gave an example of a schematic. you may NOT need an external power supply. Until we know exactly the make and model drive you are using, can't help you much more.

Marty and Keith are correct, those stepper drives need to be wired to the DB25 to work reliably. You need a breakout board and the drives wire to it. Here's a link to a breakout board from Amazon.

https://www.amazon.com/gp/product/B073 ... 1965d6ae5a

You wont need to wire up the enable line as 99.9% of the time stepper drives are enabled by default.

And here is a link to the wiring diagram https://www.wantmotor.com/Content/uploa ... -SS880.pdf

Funny i just noticed that they show a breakout board as well. My paper print from 2 years ago doesnt have a breakout board just wires. :?

Here is a link to the manual:
https://www.hobbytronics.co.za/Content/ ... gramme.pdf

I would wire
DB25 STEP1 to driver +Pulse
DB25 DIRECTION 1 to driver +Dir
DB25 COM (pins 18-25) to Driver -pulse and -Dir

Do not connect the ENAble at this time.
Wire ONE drive and motor and test If you get expected motion, than wire the next driver and test...and so on.
Do this ON THE BENCH first, not in a wired cabinet.
Shawn pointed you to a breakout board you can order.

Max step frequency according to the manual is 200k do not exceed this in Wizard Setup
Make sure you set the dipswitches correctly on the drive for micro stepping

Any reason that i cant use this one? It has wires already and wont take as much space, I will have to relocate the acorn board if i use the board style i think.

You didn't attach anything or provide a link.

Thanks Marty I apreciate the help! When i bought this kit 2 years ago they had very little info , just a simple wiring diagram with no db25 and no manual at all. I wired it up using info i found on drives that looked the same at the time and have actually used this setup to do a couple of jobs and cut out the boss cntrl panel from cnc12 samples with no issues, guess i have been lucky. I will get a breakout and wire it as you said. Do you see any reason that i couldnt use this instead of the board style?

You can use the DB25 cable with flying leads. Provided you connect the leads CORRECTLY
Suggest you make a small spreadsheet or chart with the DB25 pin number and color and match it to the Acorn Function on its DB25 and then a column to where you will land those wires on the drives. To make sure you keep things straight.
