Question #: 14276

Question: Which controller(DSP or FPGA or other) is best for CNC machine for G code interpreter operations?

Current Solution

It's probably better to use an FPGA or a microcontroller that is clocked (provided by a crystal oscillator) fast enough to simultaneously output pulse trains for the number of axes you intent to drive on the CNC and to provide for other processor operations, like spindle control, processing inputs from the machine and other outputs you may have (mist, coolant, etc.).

Additional Information:
Hi,
Thanks for the information.
Some CNC controllers having both FPGA & DSP. Is there any advantages? What is the role of DSP in this case?

regards,
Naveen

  • Which electronics package is required for the CNC machine from the book designs?

    The book design uses all NEMA 23/24 motors which can be found here:
    https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo

    I recommend the Mach3 USB option as you will be able to use the USB connection for control.

    If you are planning to build from the plans developed by the folks over at Woodsmith Magazine which is loosely based on the book design, use this electronics package:

  • do you sell plans for big machine with chain driven and how much its cost as dxf file which i can cut using cnc

    The plans or DXF files are not offered. We sell the machines as kits or fully assembled. The kits are very well priced and will most likely cost less if materials and labor than working from plans (this comes from feedback from many customers that built similar machines from plans).

  • I want to build my first CNC machine for PCB manufacture. I wish to manufacture at most A4 sizes. Which CNC kit do you recommend?

    The blueChick would be the perfect machine to iso route PCB boards. The A4 size is 8.3x11.7 inches and the blueChick is 12x36 inches. It's a bit larger, but you would be able to route many more PCBs. I would also recommend getting the 1.5 kW or 2.2 kW spindle for the blueChick since you will want very low runout to make the isolation routes (kerf) between traces very thin.

  • What is the best way to determine speeds and feeds for machine and bit longevity?

    The speeds and feeds are generally based on the amount of flutes that are being used per pass and how hot the end mill is getting when milling.  You want to use as much of the flutes as possible on single cuts.  Make the deepest cuts you can to increase the life of the tool.  For instance, if a tool that is 1 inch in cut length and the depth per pass is 1/4", then only that 1/4" is being used for the cutting.  The 1/4" tip of that tool will wear faster.  
    Make sure the feedrate is as fast as possible without a cost to the edge finish.  This will keep the end mill cool since there will be minimal friction as you are always cutting into fresh cooler material.  
    Use the end mill manufacturer's chip load for the tool to determine the starting feed rate.

    Feedrate (IPM - Inches/Min) = Spindle RPM x # of Flutes x Chip Load
    See each end mill for the chip load value.

    If your machine cannot achieve these feed rates, reduce the spindle RPM using this formula:
    Speed (RPM) = Feed Rate (IPM) / (# of Flutes x Chip Load)

  • which machine is capable of doing hardwood skulls & faces, more than just a flat surface engaving.

    Our CNC machines can be used for a variety of setups and projects, and is not limited to just the flat surfacing. However dealing with more complex designs and projects with a complete 3D object then the requirement of a fourth axis might be necessary. Also doing your project in a manner where you engrave/cut it in pieces and glue them together similar to a companion cube that a customer made (https://buildyourcnc.com/tutorials/Example-customer-blacktoe-companion-cube-portal) could be another method to use.

  • What precision do the CNC machine have, for instance the 12’’ x 36’’ x 3’’?

    Our machine that matches those dimensions, the blueChick, uses roller chain for both X and Y axes, and a 1/2" 5 start 10 TPI lead screw for the Z axis. The precision is generally related to repeatability and we have not does extensive measurement of these tolerances. The resolution is set at better than 1000 steps per inch.

  • Would any of your CNC laser machines be appropriate for welding of thermoplastic materials?

    That is a good question. We have not tried to weld thermoplastics using our CO2 Lasers. It is possible since the laser outputs a heat source and at the right intensity and speed, the thermoplastic can be heated and melted rather than instantaneously vaporized and off gassed. I have done research to see if CO2 laser can weld thermoplastics with positive results.

    Our CO2 lasers are typical of other laser cutters on the market, so if their literature, or examples you have found, successfully weld thermoplastics, then ours will probably be able to as well.

    In some cutting test with different speeds and intensities, the kerf has welded back together; however, this was caused by an unintentional process rather than an intentional one.

  • I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

    The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

    Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

  • Which machine would be best suited to cut intricate patterns into sheets of metal?

    The machine that we sell that can cut intricate designs in sheets of metal would be any of our CNC Routers/Machines.
    https://buildyourcnc.com/Item/milling

    The main consideration would be the size of the cutting/engraving bed you will need. We have CNC Machines with routing areas ranging from 1'x3' to 6' x 12' or longer.
