We have had the 5 Pro for about 3 months now and we are coming across an issue with the software. It wont read and execute some of our common cursive fonts and the V bit leaves furrowing in the middle of most lettering or logos we cut. In most cases it wont cut in a straight line and will cut going in and out taking the project twice as long. We are also getting less than stellar support from Carbide staff making this very frustrating. Anyone have any suggestions?
What e-mail are you using on support@carbide3d.com (let me know in a PM and I’ll look up your tickets).
The direction of cut is an NP-complete computer science problem known as “The Traveling Salesman” — in short, it’s not possible to have a general purpose algorithm which always calculates an optimal solution which runs quickly enough to be interactive.
The V tool leaving fuzzies can usually be addressed by running a second clean up pass at full-depth.
Could you post one of your files and a photo showing how it cut?
If a 60 degree bit is useful I bought the Groovee Jenny from Cadance Manufacturing. It works great with no clean up. It is a down cut bit and cuts cleanly even in pine. You might try that bit so save time in clean up.
Unfortunately the nature of wood is the grain has different directions. During a CNC cut the bit travels in multiple directions. So to help mitigate that try some dewaxed shellac (Zinnser Universal Sealer) on top of the project to help harden up the surface. The problem is similar to petting a cat. If you pet from head to tail the fur lays down. If you pet the cat from tail to head the fur gets all out of wack. This is similar to cutting designs in wood. Going along the grain the fibers are supported. Going across the grain the fibers are less supported and tend to get fuzzies.
If you are getting a furrow in between your simple vcarve carves look closely at your vee bit. Sometimes they can become chipped and have a rounded end instead of a point. I have a 20 degree bit that was manufactured with a rounded tip and not a sharp point. Also you may need to clean your bits because resin from certain woods build up and make more resistance and thus more heat. The heat is released into the natural product that is wood and can cause more fuzzies. I use Easy Liner Adhesive Shelf paper which you can get at Walmart and other big box stores. I use the shellac and then press down the shelf paper with a J roller. That gives you more support on cross grain cuts on wood. Time is money and running project twice takes time but may also be required to get a good result. I dont think it is particularly an issue with C3D. Cutting wood on any CNC can have these issues with wood. There is oramask in several versions but I have not had as good of success with oramask as I have had with the adhesive shelf paper and the shelf paper is much more accessible to buy.
