Thread: Chinese Laser issues

  1. #31
    OK so you press the z axis button you get a whining sound and the table does not move up or down Correct. So I would check and make sure the Belt/chain is not slipping or has fallen off the drive train, check the motor to see that it has enough power to turn the 4 screws that the table moves up and down on.
    You mentioned ajusting z axis acceleration , I'm un aware of this adjustment as Like I said its a manual adjustment you push an up or down button to make the table rise or fall. No speed adjustment seems necessary

    How does the acceleration setting for the Z differ from the X and Y? Write down what it is now and increase it in the software settings. That setting helps the stepper motor overcome any dead weight it needs to move. It would be worth a phone call or email to the Ray Scott crew to get some of the settings off the machines they sell. It would be only a starting point. To high a setting and it might jerk or make the starting movements to rapidly. Too low and the motor won't move. The motor rate as steps per mm is also a factor. This is assuming the motor is not turning, if its turning and the table does not move look for loose belt/chain or something else slipping.

    Thanks for the info. I have reached out to Ray, just waiting to hear back.

    Thanks again

    I received some info from Rabbit Laser on the z axis movement issues. They asked me the following info on the amplifier.....


    As for the z axis, what is the amplifier set at inside your laser machine? If it's not set correctly, there might not be enough or possibly too much power. Please check the dip switches on your amplifier. Then look at the front to figure out the amp draw. Please let me know the amperage.


    Can anyone let me know where this amplifier is , what it looks like, and what dip switch setting changes I may need to make to fix the issue ?


    Thanks

    Like Bert says, just call them. I am sure they mean driver but who knows??

    He's referring to the stepper motor driver. Some call them amplifiers. They should be in your electronics compartment somewhere near the board you just replaced. They are typically black boxes with wires plugged into them. Here is what mine look like at this dropbox link. (forum is not letting me upload it, probably too big...)

    There are dip switches on the driver that set the amount of current available to your motors as well as the microstepping of the motors. As Ray says if the motor gets too much current or too little current it may not work properly. Typically there is a grid printed on the driver that show the relationship to the dip switches to the current settings.

    That said, I can't tell you what they should be. Ray likely will be able to tell. It depends on the motors. Look at the switches and match that to what is on the table on the driver and give that info to Ray.
