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.

Hope this helps

 

Updated the build model and video on this build, enjoy

 

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

 

Yes you can @jesse heffley
Have a look here at some examples
Arduino stepper tutorials
Hope this helps

 

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.
Mark

 

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

 

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

Hello @finalcountdown
Yes you can build this same actuator system using a Nema 23 motor setup. You can even build it the same way with the 20 mmside of the V-Slot on end as shown


The only thing needed to change really would be the Nema 23 Motor Mount Plate and the
and the Gt3 20 tooth timing pulley

Here are a few other quick examples that this Nema 23 plate could be used


Hope this helps

 

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

 

I would look into Arduino single axis driver examples
You can also use the Arduino to control DQ542MA drivers as well.

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