### Question #: 12222

Question: What wire gauge should be used for the 36V 8.8 amp power supply

Current Solution

Most of our power supplies allow for a 9 amp current draw.

For the Neutral, Live and earth ground, wire gauge for that level of current is 14 for relatively short cable lengths. Increase the gauge for longer lengths past 25 feet.

For the DC 24V output terminals to the drivers, 20 gauge is fine. If the power supply is connecting to only one driver, increase the wire gauge to 14.

What gage wire should I use from motor to driver

• WHAT LENGTH OF MOTOR CABLE SHOULD BE USED WTIH THE BLUECHICK V4.2

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.

• My machine stopped today (after many fun filled hours of operation in the last 3+ years). I suspect the 36V 8.8 amp power supply as there is no power to the stepper motors. Is there a breaker to check, or do I need to get another power supply? Should I assume the stepper motors are OK?

Your deduction of the power supply at fault is probably correct. When you attempt to power the power supply, check the V+ and V- (COM) with a multimeter on the DC setting. You should measure 36 volts.

If there is no voltage on the V+ and V- (COM) there should be a fuse inside the power supply that you might want to check. Also, while you in there, check the electrolytic capacitors. Electrolytic capacitors have a finite lifespan much shorter than other components and are often the cause of many problems with all electronics.

Please let us know what you find.

• THE GANTRY MOUNTED SPINDLE WATER COOLER PUMP THAT I PURCHASED DOES NOT OPERATE NO MATTER HOW CONNECT THREE WIRES TO TWO WIRE POWER SUPPLY.

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.

If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

• WHAT SOFTWARE CAN BE USED WITH THE BLACKTOOTH LASER CUTTER?

If you take the standard parallel cable BoB (Break Out Board), then you will need control software (Mach 3 or EMC2) and CAM software to make your G-Code (such as CamBam). Personally I use CamBam and Mach 3, they work beautifully but don't expect to turn them on and know how they work out of the box. Give yourself a few weeks to get familiar with the basics. CamBam is VERY powerful software for it's price. I'm surprised how much I keep learning on what I can do with it...I highly recommend it if you want as much control as possible.

Mach 3 + CamBam as a bundle costs \$310. EMC2 will give you a free replacement for Mach 3 and is exclusively for Linux.

If you use the USB BoB, it will cost an extra \$75 + \$75 for the software. This is an all-in-one package so no need for Mach 3 or CamBam.

For etching rasters (jpeg, bmp, tiff, non-vectors, photos), I highly recommend PicEngrave. It has been a labor of love for the past 9 years and John has done a wonderful job with it. It easily compares in quality compared to software that is in the \$200-\$300 range. John's software runs \$40 and can be found here: http://picengrave.com/ (don't let the modest website fool you, this stuff can do amazing things). DotG and the Mach3 engrave plugin are two other options and instructions can be found on Dustans page in the gallery on buildyourcnc.com website.

Well, I've never tried particle board. I would stay away from MDF since it is pretty terrible to breathe. You can use standard ply.

• WHAT IS D.O.F OR DEPTH OF FIELD FOR THE BLACKTOOTH LASER AND LENS?

Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.
