### Question #: 13539

Question: Does the 2in flexible strip brush also come in 4in lengths for the bristle?

Current Solution

At this time, we only have 2 inch bristle length. How would you apply the 4 inch bristle? Would it be used for a CNC machine, or another application? We might be able to supply this longer bristly length if we can see a good market for it.

• What should the "glue groove" width be for flexible strip brush?

The width and height that we have on our brush piece for our cnc machines, is 1/4" width and .30" depth , the length is dependent on your specific dimension of brush and the design of the brush piece.

• for 2" Strip Brush per inch what is the dimensions (Width, High and thickness)

The strip brush overall height is 2 inches, of which 3/16 inch is backing. The strip is 1/4 inch wide. The diameter of the bristles is 0.01 inch.

• What is the dimensions and material of the spine on your Strip brushes?

The strip brush is .2 inches (5.23 mm) wide, so a slot of that width or slightly wider will work. We use a .25 inch groove and use glue to adhere the strip brushes in our dust shoe.

The material of the bristles and the strip that holds the bristles are nylon.

• If I order 19ft of the 1/2" lead screw will it come in three 6'5" lengths by default? This is what I need. Thanks

No they will not come in that length as a default, we would contact the buyer to ask specific lengths due to the total length purchased.

However if you order the 1/2" lead screw we can get them cut to the specific length you require, by contacting us here or call us at 281-815-7701.

• Does the VLXL kit come with absolutely everything you need to start up?

The Vertical Laser XL Laser Cutter comes with everything but the hookup wires and heat shrink for wiring and the tools you will need to assemble the machine and wire the electronics. You will also need a blower/vacuum to evacuate gasses in the cavity of the machine, and a compressor to provide air assist at the nozzle. 4 conductor motor cable is supplied. Water and air tubing is supplied along with the structure, hardware, mechanical parts, electronics, and chiller.

The wiring will require strippers for insulation removal at the tips and a soldering iron to solder motor wires to them motor cable. Screw drivers and hex wrenches will be needed.

Assembling this kit is not for the faint of hearts and a ton of patience is necessary. It is a very entailed process that will take a bit of time to complete. If you have any reservations at all, please consider the assembled version.

• What settings does I use for controlling the spindle in StepCon/Linuxcnc?

LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

In the VFD parameters:
PD001: 2 to accept RS485 commands
PD002: 2 to accept frequency comands
PD163: 1 to RS485 slave address:1
PD164: 1 RS485 baud rate 9600
PD165: 3 8bit, no parity, 1 stop bit

Make sure LinuxCNC is also set accordingly:

The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

In the options step of the stepconf wizard:
- Check the Include Halui user interface component.
- Check the Include custom PyVCP GUI panel.
- Check Spindle speed display

You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
net spindle-cmd-rpm-abs => vfd.speed-command
net spindle-cw motion.spindle-forward => vfd.spindle-forward
net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
net on motion.spindle-on => vfd.spindle-on

The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

Under the custom_postgui.hal file, change this line:

from: sets spindle-at-speed true
to: net spindle-at-speed => cfd.spindle_at_speed

setp vfd.enable 1

When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

• Are there any other manuals for the VFD that comes with the 2.2kw spindle?

We have manuals for the VFD rather than the spindles. Can you specify what issue you may be having so we can help you better?

I am having trouble wiring the VFD. (From the wall outlet to the VFD) I think the manual or setup guide on your website is wrong. The two diagrams show two different sets of terminals on the page.

Also, do you have a video or other documentation on programming the VFD? Your videos and documentation looks like it only covers the 1.2kw version. Are the two different spindles from different manufacturers?

• Does the VLXL feature an air jet for clearing carbon from the cut?

The VLXL does not come standard with a 1600 CFM air blower, but we do have them available.

• if I order the aluminum rail seperately does it come pre-drilled with the the mounting holes?

We can drill the holes for you. Just give us the desired measurement from hole to hole (on center). The drill size is 5/16" and the hole will be centered between the inside curve of the aluminum and the start of the curve at the edge.
