See here for the Feed pot problem - are they enabled in the software ? http://www.denfordata.com/bb/viewtopic.php?f=2&t=3623 Yes, they are enabled in the software. I even tried to disable them and tried to change feed rate via software, but the axes didn't move anyway. The signals from the potentio...

I tried to uninstall the software I was using (VR Milling 2.31) and installed VR Milling 2.16. Then the motor started working, but the brake is still not working. Then I jumped the cables to make the brake work. Now the Z motor is working fine. However it only works when I activate the brake manuall...

The Z brake has been removed and the problem with the Z motor remains ? When I removed the Z brake the motor started spinning and then stopped. What do you mean by this? Was the motor attached to the machine? If it was did it drop under it's own weight? Yes, the z axis has dropped. I put a block of...

Have you removed the brake from the motor?

Yes, I have.

Can we just verify what your problem is and what you've tried now ? The Z axis motor sometimes spins but then stops ? No, it never works. But it used to work before, it stopped working after I had to press the "Guard close" button. The Z axis has been run from a different axis drive and the problem...

Martin wrote:Can you connect the Z axis to the X or Y axis drives?

If you press the secret home button you should then be able to run it.

Exchange the drivers you mean? I did that already, exchanging the X axis driver with the Z axis driver.
Even though I wasn't able to move the Z axis.

I would try and disconnect the motor from the mechanics of the Z axis and see if it then works. Check the mechanics of the z axis with the motor removed can you turn the screw and move the axis without the motor fitted? I did that already, it does move correctly without the motor. I am able to turn...

This is the history of this issue: http://www.denfordata.com/bb/viewtopic.php?f=47&t=3878 It sounds like a power supply or wiring problem Possibly related to the supply for the Z axis brake or the pneumatic solenoids I'd be tempted to disconnect the brake, solenoid caps and Z axis stepper. Disconne...

I can't remember fitting a brake to the Z axis on a Triac. Are you sure it is not a Triton? - Yes, it is a TRIAC for sure. I am attaching a picture of it and a picture of the motor with the brake. Motor.jpg Triac2.jpg If it does have a brake then it sounds like you make have a broken wire going to ...

Also feed rate shows as if it was in 0%, no matter how I move the potentiometer. M03, M04 and M05 don't work. I used the secret button to home all axes, but it didn't solve any of the problems. There are times when I connect with the machine and it recognize the two potentiometers, but when this hap...

Hi, my name is Mauricio. I once posted a topic about some problems I was facing during routines in VR Milling software. Before I could fix it, the machine (a TRIAC NS PC) stopped working. I was having some issues with the Z axis. I believed that the problem was the motor and tried to buy a new one. ...

Is it possible that by solving the current problem the machine will start working fine?
I tested the motor without the break, does it make any difference in the tests?

Ok, I tried to swap the X and the Z axes drivers.
The Z axis continued to be the problem.
So I got the Z axis motor tested.
The motor itself was working, however when I applied 6V it was consuming 5A. The specifications say that by applying 84V it should consume 3A.

Hi,
I removed the break and tried to move the z axis. Even without the break the motor didn´t run.
It only makes a shrill noise. After removing the break I am able to rotate the motor by hand.

Hi,
Yes, I tried with the power off.
I am posting the pictures of the motor.

Ok, now I tried to take off the belt and turn the pulley alone and it worked.
The problem is in the motor. Is there some kind of break in the motor that might make this?

I tried to pull the pulley by hand but it didn´t move.
What about the other errors that are happening? Any idea?

Hi, The secret home button worked. However it didn´t solve my problem. Each time I connect the computer with the machine something goes wrong. Sometimes a message "Drive is not ready" shows up when I try to home any axis (or when I try to move any axis, after pressing the secret home button). Someti...

However every since I had to press the "Guard Close" button in the milling machine it stopped working the Z axis. I meant "ever since", not "every since". That time I pressed the "Guard close" button to make the software connect with the machine. After doing this the z axis stopped working. When I ...

Hi, Thanks for the EEPROM tip, it worked fine for the turning machine. However every since I had to press the "Guard Close" button in the milling machine it stopped working the Z axis. Any idea why did it happen? Oh, now I can connect using 57600 baud rate in both machines. But the milling machine i...
