Would like to purchase variation of Blackfoot 4'x8' , I would like to leave out the structure, add two 1/2"-1/4" couplers and switch to 1/4" drive sprockets for the X axis, and finally use two 3/8" drive screws instead of one 1/2". How should I proceed?

The dimensions for the #40 drive sprockets will be 1.835" radius tooth to tooth , .575" from teeth to teeth, 0.600" / 3/5 ID, 1.249" OD.
Now the idler sprocket dimensions (same format):
Radius ttt: 2.963"
Fttt: 0.535"
ID: 0.600" / 3/5
OD: 0.825"

I am designing/building a cnc plasma cutter and I would like some info on some of your parts. Would it be possible to get dimension and/or drawings (or models) of the #40 drive and idle sprockets?

If the machine is not moving when you use a control program to control the electronics, there could be a many reasons this could happen.

First, make sure that you followed the electronics videos: https://www.buildyourcnc.com/CNCElectronicsandWiring.aspx

The computer sends pulses from the conmputer while the control program interprets the g-code. These puses from the computer should be received in the correct form from the breakout board, or interface. Make sure that the step low active is enabled if the pin is connected to the CP- (PUL-, or STEP-) and the 5v is connected to the CP+ (PUL+ or STEP?+) at the driver.

I'm trying to test cnc with Mach 3 as it says in the book. When I send the g codes, nothing happens. I occasionally hear a bump from the machine, but there's no real rhyme or reason as to when it will bump. What could be wrong?

You need to either call us or email us, and provide the name you used when you ordered, so that we can find your order, as well as what parts you are missing.

Hi, I need the lead screws and bearings for the 4' x-axis, the 2'(?) y-axis and the 1'(?) z-axis as specified in the book 'Build your own cnc'. I am not sure which to order on your website. Thanks

Currently we do not have that modification kit, our set up is fixed for our greenBull only modification kit we have for this model is the long z-axis kit(Designed for Foam cutting).

I am building your "Green Bull' 6 foot wide kit and I am at the stage of attaching the motor and drive chain. I would like to know if you have an modification kit available to put the 1/2" ACME screw on the Y-axis?

You can get them from us. Please send an email to sales@buildyourcnc.com with your order information, or call our customer service line M-F 9-5 at 281-815-7701.

Working on GreenBull 5x10 assembly and I am missing one 1/2 rigid coupling for installing the X axis motor and chain mounts. I am also missing the two 1/2 drive sprockets as well. Where can I get these items?

If you are using shielded wire between the motor and driver, the shielded portion (the reflective jacket within the insulated portion of the wire) and any spare wires, or stranded wire should all be grounded and be inserted into the GND terminal on the driver.

When using shielded wire from driver to stepper motor, where should I connect the shielding? Should it be ground on transformer or something/somewhere else?

For setting up home proximity sensors on the PoKeys57 board, it's typically recommended to use the designated limit/home terminal or pin. This is because these ports are specifically designed for connecting limit switches or proximity sensors used for homing.

If you've already connected your sensors to the limit/home terminal and they're not functioning properly, here are a few troubleshooting steps you might want to consider:

Check Wiring and Connections: Ensure that the wiring to the sensors is correct and secure. Sometimes a loose connection can cause issues.

Sensor Configuration: Verify that the sensors are properly configured in the software you're using to interface with the PoKeys57 board. This could involve setting the correct sensor type (NPN or PNP), and ensuring the software is looking for the homing signal on the correct pins.

Test Sensors Individually: Disconnect other inputs and test each sensor individually to isolate the issue. This can help determine if the problem is with a specific sensor or the board itself.

Firmware and Software Updates: Ensure that your PoKeys57 board firmware is up to date, and that you're using the latest version of the control software.

On the pokeys57 board should I use the limit/home plug or just the block next to that plug form setting up home proximity sensors? I have them on the plug now and can not get them to work.

You should apply a spoilboard to the top surface of the machine. The bed of the machine is not intended to be used as a spoilboard.

3. The bluechick spoil board appears to be a structural member of the machine, how easy is it to replace. To start, I would assume that would be cheaper than buying your spoil board planner.

How do I wire up multiple E-stop to breakout board, does each E-stop need there own pin? If not since there are only 4 screws on stop 2 for no and 2 for nc do you just splice the wires together if your only using 1 pin? Thanks

What do I do if I didnt recieve the y-axis rails, z-axis rails, or the roller chain for my bluechick (rollerchain)?

Here is the answer to your first questions regarding the blueChick motors:
https://buildyourcnc.com/FAQ/9024

The shipping of the blueChick CNC will depend on if the machine is assembled or not. There is a duty for international orders, but I am unsure of the cost in other countries other than the US.

Thanks

I have a project very similar to cnc machine. I need 3 lead screws of 1.8 m with all set (supports, bearings...etc). and 3 NEMA 42 motors that I can connect with. if those are available, I need the information about shipping to Oman or UAE.

John Parent,

We are currently waiting for rails to come in as they are out of stock. We appreciate your patience. Please email customerservice@buildyourcnc.com and let us know if there is anything we can do.

hi, i ordered a bunch of stuff from you, the payment went through, it's been 3 weeks, any word on shipping date, I ordered 6 linear rails with block and some sprockets

The recommended total length of motor cable should be 15 feet for the blueChick v4.2

Z - 6 feet
Y - 5 feet
X- 4 feet

20 AWG 4 conductor

If your drivers will be positioned farther from the machine, you may need longer cable.

I have NEMA 34 motors for a GreenBull 6x12. After 2 weeks of use, my Y axis motor has developed play in the front but not rear of the motor. Is this a motor defect or has something come loose somewhere? Thanks,

We currently cannot release or sell any plans at this current moment! We apologize for this inconvenience, however if you email us at customerservice@buildyourcnc.com. We can help you get the current parts you will need, for a fully functional 2.2kW z-axis assembly.
