No motor movement

[cncman172]

Those travel limits are soft limits. Look at your pin config page and make sure no inputs are assigned to limits

On page 5 of this thread you had lights and movement.
What happened?

[Kutton]

The green lights were just momentary lights.
I don’t see any limit or soft limit configured.
Could the controller be bad?
Never ever have had movement.

I just looked at your wiring diagram and you only show 5V going to those drivers. Did you wire the main DC power to the servos right next to the stepper motor connections? The supply is usually 24v or higher depending on the drivers

Yes I have 24 volts going to drivers could go as high as 48 but haven’t found a reason.

Show a picture of the power supply and the connections to the drive

Kutton, do you have experience with CNC conversions, basic electrical background?
It seems as though you are struggling quite a bit.
You never posted pictures of the machine, or shared details of your machine. The control cabinet wiring etc...

We can't "SEE" your machine, we don't know how you have it wired. The more information you can provide the better we can help you.
Until you follow this post, I'm not so sure we can help get you going:

I would back WAY up, uninstall CNC12, reinstall it fresh, then put Acorn on the bench with its power supply, establish communications with the CNC PC and Acorn. If all goes well there....

Put ONE axis drive on the bench, one motor on the bench and nothing else. Connect the motor drive with its power supply, connect the stepper motor to the motor drive. Power up the power supply to the motor drive. Don't connect anything to Acorn yet. Does the axis drive power up? Does the motor energize and the shaft lock? If so, THEN connect the axis drive to Acorn using the appropriate schematic for your drive (Leadshine maybe?)

Then bench test that ONE drive and motor. IF you have problems with this one motor, show us how you wired it and which schematic you used. Lets get one motor working on the bench first. If that one motor drive and motor works, then swap in another drive and motor pair, test it, then swap in the third? drive and motor pair just to make sure all your drives and motors are functioning. When you know Acorn can turn your motor, then connect all 3 drives and motors to Acorn XYZ step/dir signals and test all three ON the bench, not on the machine. When you successfully have all three motors turning on the bench, then take careful note of the wiring and THEN mount them to the machine....

Excuse my frustration, but you can clearly see MANY people trying to help you. I just don't see enough information to go on to do that for you.

Kutton,

I am suspect you have a loose power cable or a missing common cable. As Gary and Marty suggested a few pictures would really help the people on the forum who are willing to help you get your machine moving.

You posted pictures with no RED leds on the drivers which seems to indicate to me they might not have any DC power. If you have a voltmeter that could be very useful in troubleshooting your machine. If you don't have a meter do yourself a huge favor and go to Home Depot and pick up a multi-meter for about $20. Then you can measure voltage, AC/DC, continuity, power, resistance, etc.

I designed and built this Cnc
I know you are frustrated with me, but this machine was running under Mac3. Was looking for a more dependable controller and software.
I reinstall software and got to square one. All I am looking to move is my x axis. The recast will be easy to configure.
My only problem is with step and direction on motor controller.

[cncman172]

Kutton,

If you had this working on Mach3 it should be an easy transition to get it to work on Acorn. There is a possibility you have a damaged Acorn that is always a possibility. When you power up your system do you see flashing lights on Acorn and when you start the CNC12 software it comes up with no errors? It is just really difficult to help people when those trying to help can't see what you are working. It would be like telling someone how to read a book who is blind.

Can you hook up your parallel port for Mach3 and get the X axis moving. That will verify your Drivers, Motors are still working. Do you have a meter? You can run some tests with a volt meter to see if Step and Direction pulses are coming out of Acorn. If you have a scope it is even better, but there are steps you can take to determine what is wrong.
