Question #: 14173

Question: Hey Patrick, could you get me the set screw size for the Y drive pulley on the VLXL?

Current Solution

The drive pulley we use on the VLXL is here:
https://www.buildyourcnc.com/item/mechanical-Drive-Pulley-!2-pitch-15-teeth-XL

since it doesn't show the set screw size, I will need to answer this question (and update the description of that part) first thing tomorrow morning.

Additional Information:
The set screw size for the 14 teeth 0.2 inch pitch XL drive pulley is an M4 size 0.7mm pitch screw.

Additional Information:
Thank you, Patrick!

Additional Information:
You're welcome!

  • Hey Patrick, sent you a couple more pix if you could check them out. Thank you! Ben

    Will do.

    Additional Information:
    Where did you send the images?

    Additional Information:
    phdrobotics. I think I just needed to run it slower but if you have any ideas as to how to pull that off going faster, let me know. It’s just not completely dialed in yet.

    Additional Information:
    The file that you are using should have the speed associated with each polygon/line/arc/circle. You should be able to select the layer that the geometry resides and change the speed and intensity. Are you using LaserCAD?

    Additional Information:
    Yes. But if I’m cutting a name out of a very thin material, I don’t need to go so slow. That name plate is what happens when I go to fast with a thin material. At the end of every cut point, it tries to move to the next point to fast and messes up the cut.

    Additional Information:
    Not sure if that has to do with the jerk settings.

    Additional Information:
    It's a balancing act. You will need to find the speed that works best and reduce the intensity for that speed. For instance, I typically run about 10 mm/sec to cut .22" plexiglass. You can control the depth of the cut by either slowing the speed, or increasing the power, so you have a great deal of control on how the material is cut.

    Additional Information:
    You might also want to check your belt tightness. See how that plays a role in the outcome.

    Additional Information:
    The Y is a little loose. Great machine! Just need to learn the controls and should work great. How can I switch from leftright engrave to updown?

    Additional Information:
    It's call swing. Y swing or X swing. There is a dropdown field for that in the engrave setting for the layer. Make sure to use swing unilateral so the firing only happens in one direction.

    Additional Information:
    Got it. Couple more questions for you. It’s printing upside down, not sure how to fix that. Also, how many passes does it take for you to get through 22 acrylic On 95%?

    Additional Information:
    Sent you one more picture. Thank you for the help!

  • What are the toggle switch settings on the stepper motor drivers for the .5 in. lead screw 10 tpi 2 turns per inch? Thankyou!

    On the top of the stepper motor drivers is a grid with the appropriate toggle switch positions for the lead screw being used. If it is 2 turns per inch, the proper toggle switch positions would be 01101110. Try this and see if it works.

  • Hi please could you tell me how to work out the size required for the stepper motors ? which kit to get thanks

    The size of motors required for your machine build will depend on many characteristics of the machine.

    If the machine uses a gantry (rather than moving the table bed) and the weight of the gantry (specifically with inertia),

    The mechanics used with the axes, lead screw, roller chain, timing belt or rack and pinion. Generally you will need less torque if using lead screw due to the mechanical advantage, but friction is important to consider.

    If you are building a 4'x8' or larger machine, it would be best to use: https://buildyourcnc.com/item/electronicsAndMotors-3axis-heavy-gantry-elcombo

    Otherwise: this electronics: https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo should be fine for most configurations.

    If you feel that you need extra torque on the z-axis (the z-axis will use a very heavy spindle, for instance), use this electronics: https://buildyourcnc.com/item/electronicsAndMotors-3axis-651-elcombo

  • I couldn't find any information about how to mount the "z-axis lead screw in the book" (Build Your Own CNC)

    The details will differ depending on the type of lead screw you use.

    For allthread lead screws, you will need the 1/2" square nut, 1/2" allthread lead screw, two 1/4" screws and nuts to hold the square nut in place, two 1/2" ID bearings, two standard 1/2" nuts, and one coupling hub.

    Attach the square nut to the nut support using the two 1/4" screw and nuts. The bearings will need to be inserted into the seats of the lower and upper part of the z-axis. Insert the lead screw through the top bearing. Use one of the standard 1/2" nuts and start threading it on the allthread screw just below the bearing. Lower the lead screw to the square nut and start to screw the lead screw into the square nut. Continue until the screw is near the lower bearing. Add another standard 1/2" nut to the screw and keep turning the screw until the screw just passes the lower bearing. Add the coupling hub to the top of the screw just above the upper bearing. Turn the lower and upper standard 1/2" nuts until they are snug against the bearing. If the standard 1/2" nuts become loosened, consider adding another nut to each end against the existing nut to keep them in place.

    For 1/2" acme 5 start lead screws, you will need to use an antibacklash nut in place of the square nut. This nut attaches with a flange using two #8 screws and nuts. The standard 1/2" nuts are replaced by clamping collars.

  • HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

    BYCNC response:

    Milling aluminum is no problem with our machines.

    Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

    The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

    For the dimension drawing of the anti-backlash nut, please contact us directly by phone or email to techsupport@buildyourcnc.com

  • Mach3 USB interface board. Could you please give me the correct wiring configuration for tool prob?

    Depending on the probe that you have, you should have two wires coming from the probe. One of those two wires will need to be connect to an input pin as shown in this wiring diagram (the diagram show the probe connected to pin I4):
    https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf

    The other pin is connected to V-. Please make sure that you have 24V connected to the V- and V+ on that side of the Mach3 USB board.

    The way the probe works is when the probe is in contact with an object, a specific spring mechanism will cause the input pin to be connected to the V- (close the circuit). When Mach3 senses an active low on the input pin, mach3 knows that the probe has made contact (closed the circuit).

    If your probe is used as a Z-Axis zero plate, then the concept is the same, but the end mill is connected to V- and the plate is connected to the input pin. If the plate comes in contact to the end mill, then the circuit is closed and mach3 will sense an active low on the input pin.

  • I trying to setup your USB Controller card. The planetcnc does not load the card, no driver for usb card. Using windows 8.1.

    To install the USB breakout board, there will be no driver to install nor any pop-up will be viewed in your windows task-bar, except only to notify that a USB device has been connected.

    If you have planet-cnc installed it should automatically ask for a license number, which if you don't have you will continue without entering any numbers. Please read carefully since there is a pop-up that can erase the entire firmware on your board, and you will basically have a dead board.

    Please email customerservice@buildyourcnc.com for further assitance.

    Additional Information:
    For Windows 8.1 you need to follow special driver installation steps. Download Planet-cnc software MANUAL and scroll down to that paragraph (without it you will not be able to install and use your board).

  • . I purchased the 5x Greembull recently and was hoping I could get some advice and/or plans for the torsion box and table

    A torsion box is a way to create a dead flat surface for the CNC router. A torsion box consists of an internal grid of wood that serves as the structure and a top and bottom layer sandwiching the internal grid layer.

    Here is an excellent resource on how to make a torsion box.
    http://www.core77.com/posts/26334/A-Look-at-Torsion-Boxes

    Make sure to leave 2 inches or more overhang on the top layer (3/4" thick) to make room for the rails and the chain mounts.

  • For a stepper motor that requires 5.5 amps, would you recommend setting the stepper driver to 5.43 or 6 amps? Better to go lower or higher?

    If your motor spec call for 5.5 amps, it is best to set the driver for the setting that matches that spec, or the next lowest value. This will allow the motor to run within its designed characteristics.

  • Is a cahin driven y axis that is six feet feesable? What is the best setup other than ballscrew?

    The main reason why we chose a chain driven CNC machine is to keep cost down, and works perfectly! It is also pretty simple to setup, so in your application it is feesable!
    We currently have our largest CNC machine (greeBull 6X) which runs roller chain for both the X-axis(12Ft.) and Y-axis(6Ft.).

    In longer lengths the Lead Screw, and Ball Screw will be hard to get in those lengths without any bends or having it perfectly straight at a low cost, and maybe be harder to accomplish.
    Most larger CNC machines, will have to use rack and pinion for the larger lengths, which will have a more complex assembly.
    Both the ball screw and rack and pinion will both run (mostly) on aluminum machines.

  • I need a Rigit Coupling that is 1/2" on one side and 5/16 on the other side.Can you get that for me?

    We sell both coupling hubs that can be created to your specific needs. Which will be here https://www.buildyourcnc.com/couplings.aspx and would be the bottom coupling hub's, not the rigid couplings.

    So essentially you would get the Single 1/2" Coupling Hub and the Single 1/4" Coupling Hub, and etc. for different combinations.
