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.

You can use a compressor to unclogg the water lines of the spindle. We use this method and it works every time (so far).

It seems that the water cooling lines inside my 2.2KW spindle are clogged. Is there a way to unclogg them?

The best way to determine the cutting speed is to determine this with respect to the edge quality you desire. This recommendation generally comes from the major end mill manufacturers.

The feedrate (travel speed) should be determined by the chip load of the end mill, the number of flutes, material of the end mill (Solid Carbide, HSS - High Speed Steel, Cobalt, etc.) and the RPM of the spindle. You will need to see the manufacturer's specifications of the end mill to determine this information.

Formula:
Chip Load = (feed rate IPM)/(Spindle RPM x Number of Flutes)

or

Feed Rate IPM = Chip Load x Spindle RPM x Number of Flutes

Once you find this information, apply this to the material at the full depth of the end mill. If you find that your edge condition is aberrant, pull back on either the speed, or the depth per pass. If the edge condition is acceptable, then push the speed higher until the edge condition starts to deteriorate in quality and then pull back to the accepted level.

Using this method, you will be able to reduce the wear on the end mil which will be the most expensive consumable on the machine.

If I am cutting 18mm MDF with 6mm cutting bit (so 6mm pass), what can be the maximum speed rate of cutting and spindle speed of router?

Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

I am looking at purchasing your 2.2 kw water cooled spindle. I'm assuming it comes with the VFD. I have a rotary phase converter in my shop. Are these spindles 3 phase? And if so, can I bypass use of the VFD and control the spindle speed by the CAM software instead? Or is the VFD an absolute necessity to use on the spindle?

The blackTooth's 40 watt laser tube can be cooled with simple tap water. A bit of anti-freeze keeps the tap water clean and free of algae. The cooler the water, the better output you will get from the laser. A great source of information can be found here: http://www.buildyourtools.com/phpBB3/viewtopic.php?f=8&t=3452

Yes, all of the spindles come with collets. The collets have a 1/4" (6.35mm) bore for end mills that have a 1/4" shank. The ER specification is different for the 1.5kW (ER-11) and the 2.2kW (ER-20).

According to the supplier of the 2.2 kW spindle, the safest operating speed for the spindle is 6000 RPM. The supplier also stated that theoretically, the spindle can operate from 0 to 24,000 RPM. I am continuing a dialog with the supplier to delve deeper into understanding the configurations and ramifications of such configurations for operations outside of the safe boundaries into the "theoretical" ranges.

You can actually set a current limit in in the VFD using the programming process and the specifications in the manual that came with your VFD. You can expect the spindle at 220 Volts AC to draw (using the standard formula):

For Volts, I will use 230 as the range is generally 220 to 240.

Watts = Current * Volts

Can also be written as:

Current = Watts / Volts

Current = 2.2kW (2200 watts) / 230 volts

Current = 9.6 amps

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets.

You can also use the plans from Woodsmith magazine to build a larger machine.

The greenBull CNC machine kit can cut as thick as a material as you desire depending on the reach of the end mill that you provide the machine, if it is a straight vertical. The reason for this is that each pass is incremental (multiple passes at a certain depth per pass). For instance, if you need to cut a 2 inch thick piece of wood, you can make, say 3/4" passes until the target depth of 2 inches is met.

The depth per pass, feedrate and RPM will be determined by the material: wood, plastic, metal and will also be determined by the end mill that is used for that material. Selecting the appropriate end mill is very important. Feedrate and RPM is important to make sure the end mill is as cool as it can be during the cutting process.

Spindles are generally covered up to 1 year after date of purchase. We do not repair them in house, but we do work with our manufacturer to replace defective units. Generally if you have a defective unit covered under warranty, we will issue a replacement.

Yes, we do that with our machines. You can use the rail blocks to serve as the alignment mechanism. If you have a slight misalignment, the block will not pass that joint. Make sure you use the same rail from the same supplier.

If you would like to replace a router that outputs a relatively low HP (horse power) such as the Bosch PR20EVSK or Dewalt 611, both having about 1-1.25 HP, the 1.5kW spindle would have more than enough power and will also provide constant torque where the routers are unable to achieve. The 1.5kW spindle outputs 2 HP and is water cooled to keep the dust out of the air!

The 2.2kW Spindle has many advantages over a standard router such as the Porter Cable. The most obvious benefit to the user is the significant reduction of both dust and noise.

I am interested in buying the 2.2 kW spindle. Does it run much quieter than a 2 hp Porter Cable router? You also mention a pump with a bucket of water. How long until the water is too warm to cool the spindle?

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.
