    Hi, I am new member in this forum.
    I have question about this actuator.
    Can I build this actuator with 3000 mm stroke ?
    It's possible ?
    Thanks

    Possible, yes. Whether it will be well suited to your needs is another issue. Belts stretch and this may have an impact on usability.

    For the Eccentric Spacers, what size should I get?
    6mm or 1/4"

    As the wheel kits come with 1/4" standard spacers, most purchase the 1/4" eccentrics to match. If you go with the 6mm eccentrics you need to purchase matching 6mm standard spacers for the opposing wheels.

    Has somebody count the price for this project already? Thanks a lot.

    Hi,
    Is there a practical limit to the length of the belts? I'd like an X-axis of 1000mm (or close to it). Is this too long for a 2mm belt? If I used a 3mm belt, that would be better I guess. But is this within usable length guidelines? I will mainly be using this for hotwiring foam (so almost zero effort required) but also to rout 3mm MDF.

    Thanks,
    Duncan

    You should be more then fine with this @rtfm and if you need more tension you can add one of these Timing Belt Tension Torsion Spring to the belt to take up any extra slack that may be there.

    I'm having trouble finding a way to power my motor. can anyone tell me which wires are positive and which are negative?

    Hello Jesse,
    The motors are steppers motors and require a stepper motor driver board.
    There are a lot of drivers to choose from out there.
    Have a look at the
    xPRO Controller - All in one 3 axis motion controller
    TinyG - All in one 3 axis motion controller
    Gshield - a shield for the Arduino control board
    Sparkfun stepper divers - Single drivers for steppers
    Hope this helps

    Can we use the arduino uno r3 for that?

    Hi
    I'm curious about the payload capacity of this linear actuator bundle.
    What's the maximum weight attached to gantry plates?

    Hello @wwwrrry we are in the process of having several of the OpenBuild Actuators tested for limits and accuracy so that we can share this information with the community.
    as soon as we have completed the testing we will post the information to each of the bundles part page.
    Thank you.

    Thanks @Mark Carew
    I also saw there's a new bundle going to release "V-Slot™ Linear Actuator Bundle (Lead Screw)"
    Is this kind of lead screw linear actuator provides a higher load capacity? My estimated loading is just 3 kg.

    Also, can I replace Nema 23 stepper motor with other motors with higher torque easily?

    Glad to help @wwwrrry
    Yes lead screw driven actuators will be stronger then belt driven actuators.
    Yes you can as long at the mount accepts nema 23 you can add a higher torque nema 23 motor without a problem. One thing to keep in mind is the shaft size of 1/4"
    If your motors have a different size shaft you will need a flex coupling to mach that and the 8mm lead screw size. If the stepper shaft for your new motor is 1/4" then you will be fine with the flex coupling that comes with the bundle.
    Hope this helps

    I'm having trouble programming the motor, how many steps are required to make one full revolution?

    Hello @jesse heffley
    With our stepper motors 1.8 degrees full steps are 200 steps for 1 revolution.
    Have a look at these easy to use steps per unit calculators in the Resources they make figuring out these things really easy.
    Hope this helps

    Ok, we tried 200 steps but it's still acting strangely. The motor isn't making a full revolution and it doesn't go the right direction sometimes, is this probably a problem with our connections?

    I believe that is an error in the drawing. The intent of the drawing is to show the various motor mounting possibilities/systems and it looks like as that was the focus, the belt attachments were not fully (and properly) drawn. The belt at the front would attach just like the one at the center.

    Hi,
    I am trying to lift a load of 40kgs which are supported by a pulley and a counterload(which is also 40kgs).
    So not much of a load in the motor as I have a load balancer however, I am not sure about the inertia.

    minimum lenght is around 2meters.( I guess I can extend it).

    Could you please let me know if this bundle would be suitable for me using the Nema23 motor ?

    Thanks for your reply.

    Really appreciate it.

    Is it possible to customise the bundle kit before ordering?

    The only thing I found to change was the stepper motor(include/don;t include).

    And would this carry the load that I explained above when combined with the Nema23 motor?

    Do you recommend any driver for this motor?

    Do I need to upgrade the belt? Would this be strong for the load I am trying to lift?.

    And does it only work in x&y axis? Can I safely use it in Z axis?

    And what would be the minimum increment?

    Still haven't heard back from you.
    Could you please confirm if the nema23 motor and the supplied belt with the kit would be sufficient to carry 40kg load?

    Thank you.

    Hello

    You can go thought the parts list on the bundle page : V-Slot™ Linear Actuator Bundle (Belt Driven)
    To add the parts you need to the cart. We are working on a more flexible custom cart on the future that we hope we make the ordering process much eaiser.
    V-Slot™ Linear Actuator Bundle (Belt Driven)
    Qty. SKU Description
    4 20 Low Profile Screws - 25mm
    2 60 Double Tee Nuts
    2 90 Aluminum Spacer - 6mm
    4 115 Low Profile Screws - 8mm
    1 200 GT2 (2mm) Aluminum Timing Pulley - 30 Tooth
    2 226 Eccentric Spacers
    4 480 Delrin Solid V Wheel Kit
    1 550 Smooth Idler Pulley Kit
    1 570 Idler Pulley Plate
    1 575 Motor Mount Plate for Nema 17 Stepper Motor
    4 675 Cable Ties - 4" (4 Single Cable Ties)
    1 175 Aluminum Spacer - 3mm
    1 935 V-Slot Gantry Plate (20mm)
    4 815 M3 Socket Head Screws (4 Singles)
    470 GT2 Timing Belt (Length Varies by Option Selected)
    V-Slot V-Slot 20mm x 40mm (Length Varies by Option Selected)
    1 775 Nema 17 Stepper Motor (Option)

    If you are wanting to use the Nema 23 motors you will need to upgrade to the gt3 belt/pulley because these pulleys have the needed 1/4" bore (nema23 stepper shaft size is 1/4")
    GT3 timing pulley 20 tooth - GT3 Timing Pulley - 20 Tooth
    GT3 timing belt - GT3 Timing Belt - By the Foot

    The honest answer is that we do not have this answer yet. At present we are having all of our actuators tested off site for a fair assessment so that we can provide all the necessary specifications for Builders.
    As soon as the information is available we will publish it on the Parts product page. We thank you for your understanding

    You could use the Planet CNC board and your driver of choice
    CNC USB controller Mk3/4 (4 axis)
    Planet CNC has some here - MotorDriver 2.5A - 32 - Planet CNC
    but there are many drivers out there you can wire to this board.
    These DQ542MA are very nice - 1pc DQ542MA CNC NEMA Hybrid Stepping Stepper Motor Driver 50V 4 2A 128 Microstep | eBay
    But it comes down to personal preference here.

    Hope these answers help to point you in the right direction on your Builds.
    We look forward to seeing it shared here on OpenBuilds so we can all learn
    Thank you

    Thank you very much for your reply.

    With the drivers, I will not be using it for a CNC machine. More like control(up,down) and the set length travel & return home using arduino.

    Any advice on a driver that I can use with arduino? There is just a lot of options out there which confuse me.

    How long would it take to ship to Australia?

    Really appreciate this site. Great work!

    I would look into Arduino single axis driver examples
    You can also use the Arduino to control DQ542MA drivers as well.
    help with wantai DQ542MA stepper driver for arduino

    This should help too

    Thank you for the kind words @finalcountdown
    We have a big revamp in the works that should make OpenBuilds even better! :D
    Thanks again and have fun with your Builds
