So, in the last month, did you discover that the issue was?
Just curious.

Let's start with the basics because they are often the problem.

I will assume that the mill is on a workbench or stand.
I would just fabricate a pan and sit the machine into it.
Perhaps 48 inches wide, 30 inches front to back with a 3 inch lip in front and...

How is it when cutting other products?
If your laser is cutting 1/4 inch acrylic or solid wood easily, the machine is probably working fine.
Plywoods can be tough to cut.
Some of the glues used...

The ShopBot understands G-code also.
It just looks at the suffix on the file to figure out which one to use.
For the most part, if you are using the included Vectrics software, only a few...

Just out of curiosity, how can anyone "hate" the software that comes with the FSL?
What sort of problems is he having?

A true 40 watt (33 inch long) tube should run a maximum of 16 to 18 ma.
Anything more will shorten tube life much faster than it will increase cutting speed.

Mine started by losing a bit of power (10%) and it also made a slight noise like bacon frying.
Five hours later, it was down to 50% power and one hour after that down to 10%.
My experience is that...

There are several methods that you can use.
First, zoom in so you can see the tangent points of the lines.
Highlight the 3/8 inch circle and then position it by using the arrow keys while holding...

Unless the drill is very sharp, there will usually be a small amount of tearing in wood, making a slightly large hole.
Check your feeds and speeds, and perhaps slow the drilling rpm down a bit.

I took a look through my old computer files and could not locate Version 4.01.
There was not much reason to keep older copies in that most updates were not reversible.
Once you flash to Version...

It just happens that I bought my FSE 40 watt in Jan 2011.
At the time, the machines came with Version 3.52 of the software.
For machines running XP, there was a fairly time consuming set of...

If you are brave, there are several websites and You Tubes with instructions for adding an external battery to your existing chip.

Hello again, Phil
I agree that an engraving machine is the proper device to use if one is engraving. Unless the part to be engraved is 4 feet long and weighs 60 pounds. Then the engraving shop tell...

I pulled out my notes from the conversation with Onsrud. I told them 6061 T6 and 0.022 depth. They suggested 0.004 as a chipload. With a 60 degree angle and 0.010 tip, the engraving should be about...

Hi Phil.

Hello Umesh,
Any chance that you are building a Mirror-o-Matic?
