True enough. How did you get $50 off?

Oh 50OFF I get it. I'll give it a try tonight. Thanks all.

I have heard, not yet tested, that to cut acrylic with a decent edge you need to have brand new, sharp tooling. And use coolant. I'll be trying that on some 1" clear in the next couple of weeks.

Sounds like your Z axis is not quite square to X and Y.

Well that went off the rails quickly. But thanks all.

So for my $34 I got a DVD with V7 Pro on it. Registered just fine and works very nicely so far. So I reiterate, is the $99 worth it for the V9 Pro upgrade from V7 Pro?

I just picked up V7 Pro on fleabay for $34. Is it worth it to buy the upgrade to V9?

Getting the Y and Z "embedded" with each other like that sounds like a really good idea. Nice.

Cool idea. But what happens when a bearing or ABL Nut fails? Did you make them removable?

No, to clarify. I have 2 rails per axis with 2 bearings each. 4 bearings for axis.

I used 16mm fully supported rails like you describe for all 3 axis of my MDF build. They are only as supported as what they are fastened to. If you slap them onto a 1/4" sheet of MDF they will flex...

gishere, I just made a Touch Plate circuit on my Mach3 router yesterday and now I don't know how I worked without it. Later this week, I'm planning on cutting a nice plate out of 6061.

I was...

Upgraded screws, bearings and higher voltage drivers.

Kind of where I was going. An aluminum plate torsion box will be very stout. Make it happen and you will have a LOT more stiffness. Table too.

Let me preface this with I have built exactly one machine. It works good. But still only one. Take my advice with an aspirin and a spoonful of whiskey.

For a moving table design you sure have a...

Yes. I just finished rewiring mine with shielded and grounded cable. Then I saw "encoders" on ebay for $16 and thought to myself "Self, did you just screw yourself?" But based on the feedback I'd say...

How difficult and expensive would it be to add encoders to each Axis? I have steppers with 1/2 5 start screws. Mach3 controlling.

Does Mach3 do encoders? What kind of encoder resolution is needed?...

MDF machine and I don't cut anything ferrous. Just curious if they have been successfully used for at least limit switches as I have several spares I get for very cheap and would love to clean things...

Anyone had any experience or feedback in using something like these;

Securitron Magnalock Corporation : Access Control Accessories : DPS-W, DPS-M

As Limit and Home switches?

Google Sketchup. Its free, works well enough, and does all the things you are asking for.

Thanks for the feedback. That is kind of what I figured. Thank you again for the heads up. Looks like I'll be doing more research as you recommended and assembling a 40W.

Can anyone tell me about this and if it might be a candidate?

Check the Mach3 website for suitability of a laptop. I know there used to be issues with a laptops power handling screwing things up. Once you have Mach3 up and running you just need the path files...

I found that the motors and power supplies were not well matched. Functioned but still. The motors I have work fine and the controllers do as well. But for higher voltage I think they max out around...

Ok, so I'm pretty sure I do not want to afford a prebuilt laser module. So I'm thinking CO2 tube, power supply, mirrors and focusing head. As far as mirrors and lenses go are the eBay Chinese ones...

New Faraday boxes for the electronics installed.

Got both of these as surplus from work.

Too bad Synrad doesn't have a close out section. I live not far away.

Next big question is can I use Mach3 as the controller software?

Actually it is looking like CO2 is the way to go to get any sort of reasonable cutting Wattage without going bankrupt. Is my estimation correct?

Cool. I'll need to verify what I've got in the Diodes. But I was of the opinion that I got a pretty good deal on them at the time and they all seem to function.

Thanks for the info Dave.

So I'm thinking I have some 100W 808nm (At least I think that was the wavelength) Diodes I bought a year or so back to play with. I think I even didn't manage to burn...

I'd be happy to spend under $500 but I realize that may be unrealistic.
