    Re: Stepper motor- increasing speed rotation

    How much voltage are you using on it?

    Your motor has a relatively high inductance, which will limit the maximum speed that you can get from it, especially because your driver is limited to only 50...

    Re: 1911 Gun Grips

    By any chance would you still have the link to the model that you found?

    I may take a look through sites such as GrabCAD to see whether they may have any such models, but a pointer to the one that...

    Re: TB6560ahq 4 Axis board cooling fan

    With the series fan hookup that you described, the only potential problem that might arise (as far as I can imagine) would be to the fans themselves. It is unlikely that you would damage the driver...

    Re: TB6560ahq 4 Axis board cooling fan

    While it might "work", it is probably not a great idea, especially since your two fans are not identical and so their electrical characteristics would differ.

    As the article mentions, fans are...

    Re: TB6560ahq 4 Axis board cooling fan

    The IC described in the datasheet has built-in thermal overload protection, which means that it will shut down if the device gets too hot.

    While it's likely that the part used in the TB6560 driver...

    Re: TB6560ahq 4 Axis board cooling fan

    I do not have my TB6560 board with me right now, so I was working from memory that the 12 volt regulator did not have a heat sink.

    If your board has a heat sink on the regulator, then that is...

    Re: TB6560ahq 4 Axis board cooling fan

    I would not recommend doing that unless you can first add a good heat sink to the 12 volt regulator IC on that board.

    Just going from memory, the 12 volt regulator on that board is used to power...

    Re: TB6560 driver x VFD

    My interpretation of those ratings is "maximum rated contact voltage and current".

    The relay is not providing power, rather it is capable of switching power (supplied by some other source), as...

    Re: TB6560 driver x VFD

    It is difficult for me to write instructions that are more simple than what I wrote previously.

    I think that it should be safe to control the VFD with the relay terminals.

    But you will have to...

    Re: TB6560 driver x VFD

    My interpretation of the 36V/7.5A was that those were maximum ratings of the relay contacts, and not that the relay was supplying those values.

    The relay on my board simply has "dry" contacts that...

    Re: TB6560 driver x VFD

    I'm not certain, but it is possible that the Forward Run input can be switched by a relay, where connecting that terminal to ground turns the spindle on, however that is just a guess.

    That...

    Re: TB6560 driver x VFD

    No, it is not rated to directly switch that big an electrical load.

    However your spindle is probably designed to be driven by a VFD which would typically be powered off of a 220 volt AC line, and...
  15. Re: Does the LMS solid column conversion kit make a big difference?

    Could you possibly post a photo of the X2 part/attachment that you are describing? I'm not sure that I am following your verbal description of the part.

    Re: Stepper Motor doesn't spin but makes noise

    No, I have no experience with the Marlin firmware.

    Do you have access to an oscilloscope (or to a friend who has one)? It would let you at least determine whether the firmware is actually sending...

    Re: Stepper Motor doesn't spin but makes noise

    What I was trying to get at was to see if the G-code interpreter and the stepper driver electronics were working properly (by issuing a simpler G-code command).

    If that is the case, then the...
  18. Re: GRBL with unipolar Steppers Information required

    Yes.

    GRBL does not care whether it is controlling a bipolar driver or a unipolar driver. It will work with both types of drivers and motors.

    I have used GRBL to drive a Linistepper.

    Have you also tried issuing a G91 for relative mode and then something like a G01 X20 Y20 to see if there's any movement?

    A few comments:

    For the second (Y-axis) motor, if it is a 5-wire motor designed for unipolar hookup, you will not be able to use it with the EasyDriver. The center taps of both windings are shorted together, so you...

    Re: Stepper Motor Kit

    If your signal source can drive the optoisolated inputs of the KL-4030 directly, then you won't need a breakout board.

    According to the manual at http://www.kelinginc.net/KL-4030.pdf each signal...

    Re: GRBL Connecting Arduino UNO TB6560 Driver

    There are at least a couple ways to hook it up, but this should work:

    - EN + Stepper Enable / Disable
    - EN - Ground
    - CW - Ground
    - CW + Direction X (if you're using this driver for the X...
