Overview of the three basic steps and speeds & feeds for cutting Cast Acrylic on the Sainsmart 3018 PROVer and other smaller CNC Machines. We will also review Measurements to find the thickest part of your acrylic, Using Carbide Create Pro to generate your G-Code, and editing you G-Code to go back to your home position, Hint: Add X0.00 & Y0.00 to your G-Code. And as always feel free to comment or email me if you have any questions.
For materials I am using a nominal 5mm thick CAST Acrylic, EXTRUDED Acrylic gums up the bits on these machines very easily. CAST Acrylic has a HIGHER MELTING POINT, where as EXTRUDED has a LOWER MELTING POINT. Also I am using a 30 Degree 0.1mm V Bit for the detail work, and an End Mill (You can use any Size in the 0.8mm to 3mm set) I also use the Tape & Super Glue Method to hold my material in place.

So many thanks for this video. And others based on doing this. I am just about to start, very excited. BTW? your method of masking tape and super glue is very clever, but looks messy and very expensive. Look up a product called "Kip Duoband". It is double sided masking tape. German, I think, so you may need to import it but man it should be so much cheaper, easier and less messy.

@D.E.Hammer Год назад

Your Welcome and thank you for watching. I have moved on to double sided tape. While super glue and blue tape are fine for smaller cuts, it does become cumbersome and messy on larger pieces. I have a several different brands of double sided tape, and they are not all created equally. I even tried carpet tape and that was a disaster in both the stock material moving and gumming up the bit.

You cannot edit the default tool library. But you can create a personal library & create your tools in there. Copy & Paste works from existing library.

@LVA_DESIGN_LAMPS 3 года назад

What is your finish allowance and stepover for the 3mm cutting bit? And when I'm changing a tool in carbid create i need to fill in 2D Speeds and Feeds and 3D Speeds and Feeds, but are the Feedrate and RPM the same for 3D and 2D speeds and Feeds?

@D.E.Hammer 3 года назад

So for step over I use just under half of the bits diameter. So 3mm bit I would use 1.45mm or 1.4mm. Remember that the step over is only for when you pocket or 3D, so it will not effect your cutting/contour. For 3D, those will very from your 2D. I only played around with 3D for a little bit, and am still in the process getting my settings for that. The 3D settings will not effect your Cutting or Engraving they are just for when you use the 3D carve option. As for allowance, last time I checked they were about 0.05mm.

@D.E.Hammer 3 года назад

Yes, but that is handled by the software. I personally draw all mine out in illustrator so I have a Vector file to work with in the CAM Software. Others convert a Raster Image to Vector with software. So it would be up to you to get the image you want into a file format like SVG that your CAM software can understand. There is also Laser etching photos OR if you had a STL file you could do a 2.5D Carve with the right software.

Hey, when I try to engrave acrylic sheet. It doesn’t come out clean. Like the edges are rough and small but thread like acrylic coming out. What should I do? Thanks

@D.E.Hammer 3 года назад

So I would get this when engraving when I was using the V-Bit, and I go to far down OR the bit was getting dull. By switching to a Spring Loaded Drag bit you should get rid of all of that. If you can not get a spring loaded drag bit I would cut a piece of sand paper down to about 1"x1" then fold it in half. Get a small container of water, and soak the sand paper in it. Then take the corner and go in the details and Carefully run the corner in the groves. Its not fun or easy. I would also confirm you are using Cast Acrylic.

@LVA_DESIGN_LAMPS 3 года назад

How is the noise when engraving the details stuff, is it very loud?

@D.E.Hammer 3 года назад

With the stock spindle it is fairly loud, but nothing in comparison to a more high end router or spindle. Would not recommend for an apartment with out sound proofing. I do wear protective ear ware when using, but that is because I damaged my ears from one to many heavy metal concerts in my youth.

Yep thats very important factor.....which few people ever mentions..all acrylic is not same....cast acrylic is more easily machinable...extruded is not..and cast acrylic is a lot more costly than extruded...ive had ok luck machining polycarbonate but its not as clear as acrylic....alum is similar...6061 alum cuts nice but some other cheap made alum / alloys just gum up bit ...i tried doing a cutout on a cheap chinese alum/alloy plate from inside a lcd tv and it gummed up so bad it wasnt machinable..

There are several other ways you can do this. You could use Inkscape which is free to create a vector image then save as SVG. You could use EASEL or Carbide Create (Pro) to make a design then save it as G-Code. I do have a video where I show how I make a vector image and save as a SVG in Illustrator. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dLTPEqxXfoA.html
