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.).

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:

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.

CAN YOU RECOMMEND WHICH CNC MACHINE TO GO WITH FOR CUTTING MELAMINE AND MAKING KITCHEN DOORS FROM MDF. ALSO DO PROVIDE TRAINING ON OPERATING SETTING UP SHOP PRODUCTION USE? THANKS
All of our CNC machines can cut melamine. If your application (kitchen doors) requires large cutting area, then I would recommend the following machines:

- greenBull 4x (4'x8'), 5x (5'x10') or 6x (6'x 12')

- greenLean 4'x8' vertically oriented CNC machine

- Or our Fabricator Pro 4'x8' metal CNC machine

Can a CO2 CNC laser machine be used 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.

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.

WHICH MACHINE SHOULD I BUY, THE GREENBULL OR BLACKFOOT?
The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?
The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

Would you be able to provide .DWG/.DXF files instead of .NC files for the CNC Routing Machine Kit Version 1.3 please?
These files are no longer available. We suggest purchasing a kit, like the blackToe, or blackFoot as these kits are far more rigid and perform much better.
