### Question #: 13438

Question: What CFM capacity fume extractor is necessary for vertical laser?

Current Solution

• What is the acceleration limited to with the laser tube vertical?

With our new Laser/Spindle Combo Head for our greenBull, we kept the acceleration the same and had no issues at all with the tube (regarding chipping breaking etc.). So there is no specific limit to the machine (take into affect the weight of your gantry and the overall output of your motors), but here is the setup we have now:
(with a custom greenBull gantry (4' x 8'))
X-axis
SPI: 910.069
Vel: 400.02
Acc: 12
Y-Axis
SPI: 911.023
Vel: 400.02
Acc: 18
Z-Axis
SPI: 1632.653
Vel: 79.98
Acc: 5

• What are some good ways to control the vertical laser from a Linux machine?

There really isn't any good way to use Linux when using a traditional Laser Controller. If LaserCAD worked under the Linux OS, then that would work.

Would you like to know an alternative to use Linux using maybe LinuxCNC? There are ways to do it, but you will find yourself deep in g-code and out of the box wiring configurations, most likely.

Alternatively, you can create a dual boot scenario and put Window on the other part of the hard drive. This way, you would be able to run LaserCAD.

You can also "attempt" to use LaserCAD in the wine environment, but I have a feeling that will probably not work.

We're a small family-owned electronics and hardware manufacturer, using LinuxCNC already for milling. Dual-boot into Windows isn't a sensible option -- it would greatly reduce the utility of the machine. I have more information about our use case in https://buildyourcnc.com/FAQ/13985.

Ok, fair enough. Then let's get into the details on how you can use LinuxCNC to operate a Laser machine.

Do you have an idea what controller you will be using? Parallel?

My first inclination was to use LinuCNC with the parallel interface board. Of that's the answer, then we might want to just add to the LinuxCNC discussion that's starting to firm up at https://buildyourcnc.com/FAQ/13985 rather than duplicate the information here.

I'm open to other alternatives and am happy to hack; we make PCBs and cable harnesses as a business, so that's not a limitation either. One answer might be to use one of the open source controllers that are starting to show up.

My turn for phone typos. ;-) I meant to say "If that's the answer, then..."

Good idea. Thanks.

When a direct solution is realized on buildyourtools, I will post it here.

• Can your 4' x 8' vertical laser/engraver be built with a 4th axis for engraving cylinders (baseball bats)?

Absolutely, between the ribs that make up the structure, there is room to add other peripherals like an 4th axis.

• When will 100W or 130W lasers be available for the vertical laser system? What will be the price point? Ballpark figures at least, please.

100W and 130W lasers and power supplies can be equipped now, but we will have to special order them. Price point for the 100W will be estimated \$150-\$200 more than the 80W, and 130W \$250-\$300 more.

• What issues will a user need to be prepared to solve with the vertical laser that they wouldn't normally see with a horizontal bed?

I personally haven't noticed any issues with horizontal and vertical (slanted). If there is no backing on the vertical laser (something behind the workpiece), then the parts do tend to fall out. Just keep something behind the workpiece.

On a horizontal bed, you may be able to get a bit of a better vacuum hold down, but with a machine the size of a 4'x8', there really isn't a great way to get vacuum hold down, and I haven't seen the need for it anyway.

• 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.

• Is there any precision or accuracy difference between the vertical and blacktooth lasers?

I will address the two separately (precision and accuracy):

Precision (repeatability):
This is most closely related to the resolution. The blackTooth uses the same mechanical drive (timing belts and pulley) of the same ratios and specifications, so the two machines will be the same in this respect.

Accuracy:

The output of the machine (the final physical work) matching the input given to the machine (the design data or instructions for the machine to product the physical work. This has to do with both resolution and how well the machine will hold up over time and through environmental changes.

With that said, both machines have very similar attributes in mechanics and structure. The overall structure is made of MDO (Medium Density Overlay) and has a very low coefficient of linear expansion with regards to temperature change, so accuracy will not be affected in any appreciable manner over time with the two machines. The Vertical Laser XL does use more industry standard rails to hold the heavy gantry, but this will be differ appreciably since the blackTooth will exhibit rigidity by virtue of its size.

It really is best to consider the application and size as the main aspects of deciding between these two machines.

Hope this helps.

We're looking at getting the vertical so we can run both large and small jobs on the same machine. It sounds like running a small job on the vertical (using a positioning jig) would provide results at least as
good as running the same job on the blacktooth. Does this sound about right?

• am interested in purchasing the 80 Watt Vertical Laser XL 4'x8' Laser Cutter and Engraver, what material depth can it cut?

The Vertical Laser XL's 80 watt CO2 laser tube is capable of cutting lighter material such as wood and plastic at up to 1/2" or 12mm.

• What is the wiring configuration for limit switches on the laser controller?

If you are using the AWC708 or equivalent laser controller, the limit switches will connect between the EL input terminal and the GND terminal in normally open (NO) connection. Most limit switches can be connected as NO, or normally closed (NC).

For instance, a limit switch for the X- limit will be connected from the ELX- terminal to the NO connection of the limit switch, then a connection from the GND terminal on the laser controller to the COM connection to the same limit switch.

• I have a double engrave in y_swing mode in my vertical laser machine

When engraving with the vertical laser, use unilateral movement for the y-swing. Unilateral engraving will allow the firing on the laser in one direction.

• Can the leangreen vertical laser be adapted to attach a spindle as well?

At this current time we only have the laser hybrid available for the greenBull. Due to the weight that is on the z-axis for the greenLean and the spring load, we have not tried retrofitting it just yet.

However, with enough skill and patience anything is possible. Please let us know if you try this and any lessons learned along the way.
