DO YOU GUYS SELL THE POTENTIOMETER FOR YOUR LASER SYSTEM BY ITSELF

Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

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.

HOW CAN YOU ENHANCE THE BLACKTOOTH LASER CUTTER?

check your in-going power and make sure that you have a good neutral connection. Frequently the issue is not the power supply but the power coming into the power supply that causes the problem. There is a chance that the power is good coming in but there is a loose neutral connection and that causes it. This is the neutral connection that runs all the way back to the panel in your home.

Yes, we have the optional table for the blackToe, but we need to fabricate it, which only takes one day. We generally reserve one week for the total fabrication and packing of all parts.

DO YOU HAVE BLACKTOES WITH TABLES?

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.

Yes, the greenLean can do the same type of machining as any other 3 axis CNC machine or CNC router. With 3D machining using a 3 axis CNC machine, 3D carvings can be done; however, no undercuts can be carved as the end mill (carving tool) is constantly perpendicular to the workpiece.

A 4th axis headstock and tailstock can be added to the machine for more precise 3D carvings and the greenLean can have these 4th axis units mounted within the structural ribs.

We don't offer those drive pullies with a 3/4" bore at the moment. We can supply them if you are willing to wait. If so, what is the pulley pitch, how many teeth and the width of the belt.

HOW DO YOU CONNECT THE INVERTER TO AC?

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.

HOW CAN COOL THE LASER TUBE?

Change PD001 Source of Run Commands to '1'
Change PD005 Max operating frequency to 400hz
Change PD004 base frequency to 400hz
Change PD003 Main frequency to 400hz
Change PD006 Intermediate frequency to 2.5
Change PD008 max voltage to 220v
Change PD009 Intermediate voltage to 15v
Change PD010 Min voltage to 8
Change PD011 frequency lower limit to >100hz (120hz to start)
Change PD142 7 Amps
Change PD143 2
Change PD144 3000

Note: PD001 had to be changed back to 0 to allow for keypad control.
Note2: I had to reverse U and V to get the spindle to go forward in FWD. (reverse any two wires, u&v or w&v for example)

HOW DO YOU SETUP THE SPINDLE INVERTER?

These tubes are rated for 18mA. The power supply is able to push up to 21mA. This is a very dangerous thing to do. If you are pushing the tube beyond 18mA you will cut it's life by QUITE a bit.

What is the model number of the laser controller?

Additional Information:
Hey - the model number on the laser controller is
AWC708C
S/N:708014243

Additional Information:
Do you need any additional information here? I really want to get going on it this weekend!

Additional Information:
Sorry about that. If you are referring to the CN1 and CN2 connector, I don't believe it is needed if it didn't come with the connector. The components that we send to the customer is the same package that is sent from the manufacturer of the product. I would try connecting it to the CN1 connector of both units and test the interface (control panel).

Additional Information:
The manual for the AWC 708 shows the two ports CN1 and CN2 connected, but that may just be for thorough documentation if the CN2 is needed for some reason. Do you have a copy of the manual or know where to find it? If not, I will put the document link here.
