Question #: 13895

Question: What profile do I use in VCarve for a BlackToe?

Current Solution

The blackToe is a CNC Router based on standard CNC Routing and milling actions. If you are referring to a profile machining operation (where the path follows the inside or outside edge of a polygon, line, arc or circle) then the profile is actually more a function what you want the CNC router (blackToe in this case) to do. A profile expects a specific end mill in the spindle and requires the specifications of the end mill in the profile operation.

If you are referring to profile to mean "post processor" or specifications (profile of the control) for the g-code interpretation for a specific control program (like Mach3), then you will need to set the post processor in VCarve post-processor to the control program you are using.

Please provide more specific information here so I can delve in a bit deeper.

  • What is the footprint of the blacktoe 4x2?

    The footprint of the optional blackToe table, is from its most outward points (73" inches x 34" inches) and for the gantry itself (36.5" inches width x 17.25" inches length x 29.5" inches height).

    Additional Information:
    Thank you. Let me ask a clarification question.From this description, can I presume that the 4x2 router kit can be attached to a torsion box-like table that is 73"x34", has a two inch overhang, and four inches of space below the overhang, and that the fully assembled unit will fit in a space that is 73" long by 36.5" wide (with a little bit of clearance, of course)? If I have extra space in the long direction, can I get longer rails and extend the table?

  • What settings does I use for controlling the spindle in StepCon/Linuxcnc?

    LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

    The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

    Additional Information:
    After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

    Additional Information:
    To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

    Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

    In the VFD parameters:
    PD001: 2 to accept RS485 commands
    PD002: 2 to accept frequency comands
    PD163: 1 to RS485 slave address:1
    PD164: 1 RS485 baud rate 9600
    PD165: 3 8bit, no parity, 1 stop bit

    Make sure LinuxCNC is also set accordingly:

    The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

    In the options step of the stepconf wizard:
    - Check the Include Halui user interface component.
    - Check the Include custom PyVCP GUI panel.
    - Check Spindle speed display

    You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
    loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
    net spindle-cmd-rpm-abs => vfd.speed-command
    net spindle-cw motion.spindle-forward => vfd.spindle-forward
    net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
    net on motion.spindle-on => vfd.spindle-on

    The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

    Under the custom_postgui.hal file, change this line:

    from: sets spindle-at-speed true
    to: net spindle-at-speed => cfd.spindle_at_speed

    and add the line:

    setp vfd.enable 1

    When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

  • I purchased Mach3 from buildyourcnc dont know what verson i need to use in VCarve as the processor. There are 8 2/3Mach listed

    You will probably have post processors like the following listed:
    Mach2/3 ATC Arcs (inch)
    Mach2/3 ATC Arcs (mm)
    Mach2/3 Arcs (inch)
    Mach2/3 Arcs (mm)
    Mach2/3-WrapX2A ATC Arcs (inch)
    Mach2/3-WrapX2A ATC Arcs (mm)
    Mach2/3-WrapY2A ATC Arcs (inch)
    Mach2/3-WrapY2A ATC Arcs (mm)

    If you have an Automatic Tool Changer, use the post processor with the ATC in the name. For most applications and if you don't have an ATC (automatic tool changer), use the Mach2/3 Arcs (inch) or (mm) post processor.

  • My question about motor tuning for the blacktoe in Mach 3 was for the aceleration and velocity settings what are the recomended settings

    In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

    The steps per inch is dependent on the microstepping:
    Steps/Inch for the x and y
    Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
    Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
    steps/inch = 3200 / 3.5 = 914.28
    This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

    Velocity:
    Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

    Acceleration:
    Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

    The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

    Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).
