This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

Additional Information:
I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

Additional Information:
Thanks for the information. Can you let me know the model of the VFD that you have?

Additional Information:
VFD Model # YL600-2S-2K20

Additional Information:
Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

Additional Information:
Does your VFD have a VI terminal?

Additional Information:
No, it does not. The terminals for this VFD are as follows (seperated by dashes "-").

10V-AI1-AO2-PLC-DI5-DI3-DI1-COM
AI2-GND-AO1-DI6-DI4-DI2-FM-24V

Additional Information:
Do you have a PD070 parameter?

PD070 is the main Analog Input parameter.

The options for that parameter is:
0: 0-10V
1: 0-5V
2: 0-20mA
3: 4-20mA
4: 0-10V (4-20mA Stacked)
5: XIA
6: (VI+XIA)/2
7: (3VA+XIA)/4
8: (XIA_XIB)/2
9: Max (XIA, XIB)
10: Min (XIA, XIB)


Additional Information:
There is a PD-00 thru PD-09. PD-07 is currently set to 0.

Additional Information:
It appears that the manual I’m using “Titled YL600” is not the same as your unit. I will check our manuals and find the one that has only PD-00 to PD-09.

Additional Information:
For that VFD, the parameters are P0. The 0 may look like a D on the display.

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.

Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.

WHAT ARE SOME USEFUL MODIFICATIONS CAN APPLY TO THE BLACKTOOTH LASER CUTTER?

The blackTooth build instructions explain how to hook the four LED control panel to the USB breakout but not the Parallel BOB. Turns out it's very easy. Simply wire the corresponding LED cathodes (top pins on the display) to the matching CP- for the X, Y, and Z axises and wire the anodes (bottom pins) to the 5V terminals. For the on/off LED, wire the cathode to the G terminal on the laser power supply and the anode to the 5V laser supply terminal. Also, remove the 5V wire running from the Parallel BOB to the 5V terminal on the laser power supply. It is not needed and will cause the laser on/off light to always be on if the USB cable is connected.

HOW DIFFICULT IS IT TO BUILD THE BLACKTOOTH LASER CUTTER?

The lens is 20mm wide and a 50.6mm focal length (the one included). This lens will stand up to at least 30PSI air assist.

The mirrors are 25mm wide mirrors.

Focal length is the distance from the lens to the material for the laser converge into the best focal point. If a lens is listed as 2". You measure 2" from the lens to the material, this will be the tightest point the laser can go before it starts to re-expand again losing focus.

For our redLeaf CNC computer system, if the computer system section is none response check if you have power coming in from your wall outlet. If a spare PSU (power supply) is available, try replacing and running with the replaced PSU.


Additional Information:
Other considerations will included, RAM module (memory stick), and motherboard. Please verify you have power going to your motherboard first, by noticing if any LED's are turn on. If not Check PSU first.

Additional Information:
Yes there is power to the unit. There is a small green light lit on the motherboard and another green light lit near the usb ports. Usually when I press the yellow reset button, the computer starts, but now nothing happens...

Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.
