I bought my machine 2nd hand many years ago. It has NEMA34 motors with the basic, standard setup and a 3.25HP PC router. I've never gotten the machine to cut reliably. The machine generally feels...
On your average DIY router, you're going to want to run something like 40-80ipm w/ a DOC of something like .02-.05". A little WD40 and a lot of air goes a long way. Air is especially important.
...
Long story short, I don't use it enough to justify having it so I'm seriously considering selling it.

The part is roughly 13"x8.5"x.75". Wood is supplied by a mill that does molding in house so the quality is better than what you'd get at a big box.
I have a project to cut 60 crosses out of hardwood. This is a little out of my comfort zone. I normally machine plastics for signs primarily but I figured why not take a shot at it.
I tried...
The thin plastic is commonly referred to as engravers plastic or laminate plastic. Some people also refer to it as Rowmark (brand name). Rowmark, IPI, and Gemini Duets are 3 of the main...
You can buy 1/2" PVC from Home Depot for $80. Veranda HP 1/2 in. x 48 in. x 8 ft. White PVC Trim-H120AWS6 - The Home Depot Would I recommend it for this? Probably not. I'd use Medex MDF over PVC....
I hate to break it to you, but if you don't have power then you can't get vacuum. 230V and 30A isn't a crazy amount of power. It's roughly the same amount of power a home stove or clothes dryer...

Assuming you're running a DIY machine that is best categorized as a light duty commercial machine, I would think that the black box...
I've done ACM like the OP is talking about. Normally I would profile cut everything with an upcut bit. No ramping. Although I haven't had his problem, if I did, I would definitely pocket the...
Pocketing will definitely resolve the issue. Likely switching to a upcut bit will as well. I can see why you want a downcut. It's going to give you the best edge quality considering you're putting...
Do some research on lasers and you'll quickly figure out why it's a bad idea to make a laser/router combination. The quick answer is dust and laser optics are not friends. Get some dust on the...
The way these machines should home, which is based on what I've read and what I've experienced, is you home to the Y first. Then home to X (both motors will move together). Then home the A slave...
I found the write-up on the website to be incorrect when I installed my own limit switches a 18 months ago. This is what I did on my regular 48x96, which is one of the first complete kits sold. ...
I have a company that wants me to cut a 16"x46" oval out of .04" aluminum. I've never cut just aluminum that thin. It's always been thicker aluminum or thin aluminum laminated to another substrate....
Pretty much used the settings above since my compression bit that I ordered didn't show up today. Everything worked out fine. The edge quality on the ALUPANEL wasn't quite as smooth as I would have...
Hi. I have a couple of "rush" projects and I've done my research but I just want to confirm the settings I'm going to use. Also just wanted to see if there was anything else I should know before I...
All is right with the world, to some degree at least.
What I did:
Mechanically:
1. Cleaned, tightened, and lubrated the drive system.
2. After discussing it the problem with Ahren, I took...
Found some settings in Mach3 through some googling and curious what people's opinions are?
First, my accel was set at 20. I brought it down to 15. Good idea?
Second, changing from constant...
It's definitely losing a step. The amount it moves varies obviously but the machine can jump anywhere between .125-.5in out of square measuring from the bumper plate to the gantry risers.
As far...

Thanks for all the responses. I'm going to move forward with the limit switches as is and spring load them to hopefully ease the brunt of a boo boo if, or should I say when, it happens. I spoke to...
I purchased a used CNCRP4896 machine about 3-4 weeks ago. I've been going through it, learning with it, and cleaning it up. I'm up to limit switches. I bought some NPN Proximity switches and they...
Is there anyway to anodize in another color? Apple uses a grey anodizing on their products which lasers well for example. That seems like the most obvious and cheapest solution if possible.
I...
People have lasered anodized aluminum for years and years. Google it to see what it looks like. Any laser can mark colored anodized aluminum. What you're left with is a whitish mark that isn't...
FYI, anodized aluminum engraves on a laser without any additional coatings. It marks white.
I don't know much about Galvos but I do believe he's going to have a hard time cutting with the galvo unless he ends up buying a very expensive model. You could get two machines, one to cut and one...
Fair enough about the material selection. You should seriously look at Trotec if speed is a concern.
One other thing to mention about Chinese machines, where they lack in rastering speed they can...
If speed is your #1 priority, you have to look at Trotec.
I'm still curious why you're using white acrylic for this kind of work. IPI or Rowmark most likely have an acceptable product and I'm...
First, why are you using acrylic for this when laminated plastic exists? MUCH better choice for this process and is actually considered the norm in the industry.
Second, for raster engraving...
