The Chinese developed a CO2 laser that was cheaply made solely for purpose of making rubber stamps for your signature for official documents. But I have no idea when they first began making them. The CO2 laser was invented in 1963 and the oldest reference on the internet I can find for someone in the US buying one of these units is from 2008 off of eBay.

Current K40 laser

These things have been around at least since then, and maybe a couple of years before. Pre Pandemic you could get one for about $300. Now they are about $450 and currently are affectionately called the K40 as they are 40 watt CO2 lasers.

They originally came with a control board that only worked with software called Moshidraw and I can find no real timeline for that software development either.  I believe that board was referred to as a Moshi board.  The DIY folks began developing boards for these lasers and that continues to this day.  Until recently I owned my own K40 and while they looked pretty polished the purchaser had to upgrade and mod these things to make them sing.  You almost certainly had to add a control board that was compatible with laser software such as Lightburn.

I’ve written this article before, but it bears repeating, I think.  I just got a new laser, which means  I joined a new Facebook group and I’ve seen this happen so many times from every manufacturers Facebook or Webpage Forum.   A group member will write:

“HELP!  My machine stopped working and I have orders that I have to fulfill.  I am frantic, HELP!”

Please know that I’m not knocking anyone here and I don’t think I’m smarter than anyone else by a long shot.  I just want to point out some observations I have made over the last few years of operating a laser.

If you have bought a laser to run a small business and:

• Don’t know how to troubleshoot your machine.
• Don’t have lots of experience with the machine.
• Don’t have spare parts.
• Don’t have a backup machine
• Don’t have a fellow hobbyist who can help with your orders during your downtime.

Then all I can say, is that you didn’t plan out your business very well.   Lasers are electronic, mechanical, and optical devices.  There is a lot going on there.  They break.  Sometimes WE break them.  If you have a laser and you are just a hobbyist making stuff for yourself and your family then you can afford the luxury of waiting a week or two on parts.

If you are in business you can ruin your reputation in a hot minute by not delivering what you’ve promised.

xTool RA2 Rotary Pro Review

FULL DISCLOSURE – I was provided an xTool D1 Pro with an RA2 Rotary Pro at no cost to review.  xTool has in no way attempted to influence my review. 

I’ve been given the great opportunity to review the xTool D1 Pro and included in the kit was an RA2 Rotary Pro.

There are a lot of videos online that show the RA2 but most of the ones I have seen are familiarization, and unboxing videos.

I appreciate all these reviews and learned a lot from all of them but when I get my mitts on a piece of gear I want to fill in the gaps that others may not touch on and I will discuss Lightburn settings quite a bit in this blog.

Regarding unboxing though……….my kit was missing the small bubble level.  Obviously that doesn’t affect assembly or use of the machine so it won’t affect anything discussed here.  Actually I have a couple of those mini bubble levels around here somewhere so no harm, no foul.

xTool D1 Pro Review

Full Disclosure – xTool provided me an xTool D1 Pro at no cost to review.  They in no way whatsoever influenced this review.  

NOTE:  Almost all my testing is done with Lightburn using the configuration file xTool provides here.

It doesn’t take me long to tell whether something is great, good, or problematic.  In the case of the xTool D1 Pro my conclusion is landing somewhere in GreatLand™.

I’d be remiss in not mentioning that I have considerable desktop and CO2 laser usage and I know just what to do to reveal problems right away.

While waiting for my D1 Pro to show up I began asking people questions and joining forums and groups.  The first thing that hopped off the page for me were people asking “How do you keep things straight?”

STRAIGHTNESS

I’m going to refer to this as an “issue”, and not a problem because almost every laser made, maybe with the exception of industrial lasers, don’t have any immediate method of straightening.   Someone I know owns a D1 Pro and has the honeycomb kit . I asked him to provide me any input before I received my machine and wrote my review.  One of his bullet items was:

“The honeycomb panel set isn’t currently able to be fixed to the machine itself in anyway, which makes it very difficult to maintain square between the panel and the machine itself. “

There are a couple methods for overcoming this issue of keeping things straight.

xTool D1 Pro

FULL DISCLOSURE – I was contacted by xTool and provided this xTool D1 Pro Kit to review.   This is just an initial impression following my build out,  with a further, more in-depth review to follow soon.

XTool D1 Pro

My laser is the 20 watt version with the RA2 Rotary.  It has an impressive working area size of 430 x 390 mm (16.93 x 15.35 inches).  The published Z height is 50 mm (2 inches).  I suppose they had to put some number there but the reality is you can laser an item of just about any height if you raise the laser with the included riser legs or 3D print legs or stack soup cans under the legs. The Z height can be just about anything.

As usual I won’t spend time with videos showing the unboxing or reposting things you can find on their product information page.  If you are looking at this blog and have an interest in getting an xTool D1 Pro you’ve already looked at their page and me re-hashing a picture of the box and listing the specifications (other than the ones I listed just above)  is simply redundant and a waste of your time.   Here on my blog I get something, use it, sometimes in ways it wasn’t meant to be used, and then tell you what I think.

The first thing I want to say about ANY LASER is that you probably think you’ll buy one and start whipping out crafty things and soon become a millionaire, or at least be the talk of the town.  Some of you might.  But most people that buy them have no laser experience, no experience with other items that travel along an X, Y, and Z axis.  They also have limited graphic arts abilities, and minimal abilities to repair malfunctioning electronics.  I basically just described myself at one time, so don’t take that personally.

But I will say this before I start my review.  If you buy ONE machine to run a business, that is a business model designed for failure.  If you are in business you need to plan for downtimes.  That may include owning TWO machines, or having a kit of repair parts.  It might even involve having two computers in case one fails.   Lasers are electrical, mechanical, and optical devices that can break.  Diode lasers degrade over time.  All I am saying is don’t buy one machine, and then run that machine to failure and then declare it to be junk when you have orders you can’t fulfill.  Rant complete.

On with the build and review!
