For squaring, I had good results with the 'five cut table-saw sled test' https://www.youtube.com/watch?v=RZ_nzvYEZ-4, https://www.youtube.com/watch?v=oCwQn40GsVs

For my tests, I made a fence along...

The 'digitizer master.dxf' above works for me. Anything you see posted that downloads from MegaUpload is forever lost though.

The pen holder pdf appears missing, but likely the same as this...

I usually surf youtube for clips of others cutting new materials. Here's one for Poly that may be useful - VELOX CNC router cutting plastic - .500" deep with 3x3 machine - Polycarbonate - YouTube

Onsrud has an online tool with suggested bits/feeds/speeds for plastics- Plastic Routing - Router Bit Search and Shopping Cart

Try Waterlox. It's Tung oil variant with high solid content. I'm not sure about non-US availability though.

Here's a great example of what you can do with the HF DC. Adding a primary with a Thien baffle and a pleated filter works wonders.

Single flute bits can get you closer to optimum speeds. Cutting with a high rpm just wears out bits because they heat up too much.

Very cool tool.

A few questions:
How do you save the results? I know this is reaching, but can you save as a vector file?

Also What does the 'Scara g' field control? I assume it's dpi, but...

Have you tried swapping out the switch? I had something similar on mine, and I think my switch was bouncy or on the way out.

My theory was that it triggered and opened the switch, backed up...

Mariss,

I'd sincerely appreciate if you could put the smoke back in the bottle. In the off chance that it's truly toast, hopefully you can find it useful as a field example, but please feel no...

Good to know. I'm surprised and disappointed that Gecko didn't put replaceable fuses on these.

I'm not sure what he did to start the downhill slide, but he ended up rigging a doohicky with more...

I pulled some numbers off of the Vortex chipload chart (http://www.vortextool.com/images/chipLoadChart.pdf) and my router manual for my feed+speed chart. As it took me a good hour, maybe someone else...

The previous owner had the output hooked to an automotive relay (for headlights) and it was limping when I bought his kit.

If you're going to use the output to control your router, I strongly...

I'm not yet sure about their cnc longevity (I'm a recent cnc convert), but MLCS is running core box and v groove sets for cheap (5@$35) right now. They have served me well for normal router work.

Are you thinking of a plunge ogee? Amazon.com: CMT 848.191.11 Plunge Ogee Router Bit 1/4-Inch Shank, 3/4-Inch Overall Diameter, 7/16-Inch Cutting Length: Home Improvement

You can do the PS3/Xbox controller mod to add the last two and the E-stop. Run the X/Y/Z/A on one input, then touch on another. If you home A separately, that would use a third.

I think this is a great idea and one for my project list. I saw where someone had made a zeroing jig with a piece of copper pipe embedded in a chunk of Lexan with a centerpoint in the middle, but...

Hey Gerry, did you make or buy your cam clamps?

I'm new to CNC, but I did figure out one time-saving tip for 8020. As the slots are 5/16 wide, if you want to run limit switch wiring/etc down the...

Stranded isn't usually used for cabling runs but for sections that get moved often, like patch panels, cnc routers, etc. If you look carefully at the wires in the plug, you can usually tell if it's...

I'm using Cat5 and these BOB's from cnc4pc for my Z plate and it works just fine. (G540/Mach3)

If you're running Cat5 that will flex a lot, check that it's stranded cord.

Ditto to Ross. If you're on a budget, get a HF dc, then a 1micron bag, then cut and add a Thien baffle.

If you want to skip to the end, I did the full out mod like this guy did: Harbor Freight...

That jig is definitely going on my list of projects. This was just for quick, temporary attachments.

I've been lurking on here for the past couple years, but finally found an opportunity to buy an FL200 style cnc router locally off Craigslist. As it was already assembled, bolting additions on...
