Question #: 14950

Question: [4'x8' CNC Machine (blackFoot)] I have a Blackfoot and have a question about the power supply. I currently have a 36V power supply and my machine bogs down, would a 70V or something like that help, or will that blow up my machine? thank you!

Current Solution

I would first check the mechanical parts to ensure smooth motion. Is your machine bogging down during cutting or jogging/rapids?

You can increase the voltage to gain a higher speed for rapids/jogging, but make sure the driver can handle this voltage. There should be a max voltage on the driver label.

If the bogging down is happening during cutting, either reduce the cutting depth or switch out the drive and motor for the axis that is giving the problem.

I'm interested in getting the CO2 laser & Spindle for my Blackfoot - I currently have just the router mount. Do you sell complete kits or can you advise on what I need? Thank you
Yes, if you want a laser on the machine, I would highly suggest that the laser be mounted on a separate gantry, similar to the following image:

You would need to develop the gantry structure, but you can use this thread to work out the design with my guidance.

You will need a laser tube, laser power supply, laser controller, mirrors, mirror mounts, lens and nozzle. You will also need some mechanical parts and some motors, drivers and power supplies for the drivers and the controller.

I have a Blackfoot that was purchased in 2017, after the purchase we moved and I haven’t been able to find room for it... would you be interested in buying it back or trading for something smaller. The Blackfoot and computer have never run but I did purchase it assembled. Thanks in advance, scott
The blackFoot uses the same electronics and motors as the blackToe (2'x4') machine. The only parts that change are the gantry horizontal structural parts which may be relatively easy for you to change. We can send you those parts if you are interested in a smaller unit.

I am having trouble connecting the cambam program with my Mach3 to my 4X8 Blackfoot CNC machine. Where can I get help on this issue. Have had my machine since 2015 and have not been able to use it. Thank you
CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

Hi, question about blacktoothv2 laser engraver, what is the cutting area of the laser machine as I don't have clue how big it is, and are you’ll just use it like that ore it’ll have a moving Z axis, waiting for video 5, interested how it will progress. It’ll be very useful if you’d mention some dimensions during the installation. Thanks and keep up good work
The lasing area for the blackTooth v2 is 20" x 24" or 580 x 600 mm.

The dimensions for the machine in general will be on the main product page when the videos are completed.

Thank you for the kind words.

On the blackFoot 4'x8' CNC machine do you have the instructions under one file that I can download, I want to print them out and make notes as I am building the machine.
WE don't have an actual file that contains the instructions for the machines as they are a part of a larger database file that is queried during the product page's rendering in the browser. The best option would be to print the webpage on a printer and use that as notes.

I know this will not provide larger images, but you could use the paper version to write your notes while assembling the machine using the larger images on the website.

I purchase blackfoot cnc machine 4.1 resecentily cnc mech 3 upectedily plunging.I will cut one part and its fine the second I notice that it upectedily plunges and I dont have clue.. please help.
If your CNC Router is plunging unexpectedly, it may be stalling in the upward movement. Check your velocity and acceleration for the z-axis. Recommended values for the blackFoot/blackToe CNC routers for acceleration and velocity is 80 ipm for velocity and 7 to 20 for acceleration. Test at the lower values to see if that helps. If it does help, then increase the values until the problem happens, then lower the values.

If the acceleration is too high, there may be a stall at the beginning of the axis travel because the motor cannot compensate for the inertia of the axis assembly. If the velocity is too high, but the acceleration is low, then a stall may happen at the motor's top speed.

I HAVE ONE OF YOUR SMALLER STEPPER MOTORS RUNNING MY X AXIS BRIDGE CRANE AND IF IT IS MOVED TO FAST THE MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?
Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you
I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

I have wired up my 110v VFD and my 2.2Kw spindle and I get an E.Lu.5 code. My wiring is correct and the parameters are set to those for the VFD according to your website I found in a previously answered question from someone here. Any help would be greatly appreciated, thank you!!
The E.Lu.5 Error code on your VFD is related to Low Voltage.

The recommended action is:
- 1. Check whether the input voltage is normal. (the voltage from the wall/breaker to the VFD)
- 2. Check whether there is a sudden change in load.
- 3. Check whether there is any phase missing.

Unfortunately, these three recommended actions will probable require an electrician to test the line going into the VFD.

I purchased the spindle cooling kit with power supply. and was wondering if you have a diagram on installing or a video. thank you
The 12V power supply has 3 terminals for AC in: N, L and earth ground. The output of the 12V power supply has 2 DC + and - terminals. Cut the connectors off of the ends of the fan and pump wires. Strip the red and black wires of both units. The fan will connect to the 12V power supply red to the + and black to the -. The pump will connect in the same way, but the white is not connected.

I have a Blackfoot 4x4 v2 chain drive. my Y plate is broken . do you sell just the Y plate or can I buy just the Y plate spec plan? I love this machine Its great. my name is Jeff Krug I bought the complete package and electronics from you guys. thanks
Sure, email me at customerservice@buildyourcnc.com and I will send you a replacement for a minimal fee. I now use HDPE for that part. The HDPE holds up much better.

[311] I am looking to use this type of thing with a pipe for theater. Where the pipe can be lowered and it would have electrical and signal cable inside. Is this good for that or should I look at something else?
This would totally work for that application. This cable carrier is used for any object that needs to move and carries some electrical or tubing within it. This cable carrier is great for cable management where you want to make sure the wires and tubes are in a position that you set, not where the wires and tubing want to go.
