Enco 9x20 build - Steppers not moving!!

Hi everyone!

Trying to get my conversion completed with this Covid-19 vacation!!

Got the machine built and just finished up the cabinet - wired up the steppers and they are not responding. I believe they are getting power as they lock tight when power is turned on.

Pretty sure this is the stepper kit I have - bought it 3-4 years ago: www.automationtechnologiesinc.com/produc...6050-stepper-driver/

Here is the wiring diagram I used minus the "Y" axis: www.automationtechnologiesinc.com/wp-con...014/09/ALLDriver.pdf

I did wire in a relay to start and stop the spindle motor and it does work as it is supposed to so i assume the 25 pin cable is good - i did ohm it pin to pin and it checked good.

Can you folks look over the attached pictures? I probably just missed something stupid and keep looking past it as I troubleshoot.

I do have a CNC retrofit mini mill also with LinuxCNC that I bought already built and have used for years - so I probably understand just enough to be dangerous!! LOL!

Thanks, Jeff

I am trying to add more pictures - they were too large of file sizes!

Bear with me....

Yes, the motors are locked when power is on - once you turn off the power you can turn them .
No latency error.

Okay, driver dip switches are set to 2 micro steps (switch 5 off, 6,7 and 8 on) - changed both X & Z stepconf to 2.0.
Changed step time and step space to 10000 in stepconf and it didn't get the motors moving.

How is the BOB being powered as looking at pic3 I only see one lead going into the power on the BOB

If i interpret correct you can set the 'commons' of your outputs to either gnd or 5v plus eventually pullups. Try to measure if your outputs have signals on the bourns.

Clive,

In the bottom left corner is the 5V power supply - I wired it according to this diagram www.automationtechnologiesinc.com/wp-con...014/09/ALLDriver.pdf

Am I missing something else?

Thanks, Jeff

Mike,

Are these "commons" on the BOB between outputs 2&3 {X axis} and 6&7 {Z axis} ??

How do I check them? I have a multimeter- assuming they will be 48VDC - when do I check them? When attempting to move the axis?

Thanks, Jeff
