Re: Gear Maker-Be aware of these limitations:

Good point. I have another method: - move the gear center to x0/y0 - tweak one tooth/one notch in node editing mode as desired (I usually extend the notch bottom round) - cut the vector at the beginning/end of this tooth/notch segment and delete the vector with the unmodified teeth - rotate/copy the...

Re: Cut multiple node intersections at once

The theory being that you'll get the pockets you want separated by very small space as the bitmap to vector function traces on "both sides of a line". Wouldn't an offset inward accomplish the same thing? Theoretically an offset in both direction should do the job. Unfortunately Aspire seems to get ...

Re: More Koru Fibonacci

I see what you did and the result looks great. Question for me is why not cut it from one piece? Was it material saving or machine size?

Re: Chisels

........But yea, I agree, picking up a top quality tool and using it is very satisfying........ I my case it was rather buying a set of quality tools (the Narex bench and mortise chisels sets) with the optimistic intent of making more handcrafted items. However as it turns out I usually take to chi...

Re: 2 part ? reducing drill deflection and engraver chatter

The anodizing layer is aluminum oxide (aka sapphire) and very hard. A drill bit with a tip tends to wander around until there is enough pressure to break the thin layer (you may notice the powdery substance). Not sure if that can be totally avoided, especially if the bit is long or the machine not v...

Glass/Jar/Shaker Holder

Another one of my simple utilitarian projects. The problem to solve was keeping the most used implements on the table of our 5th wheel trailer while traveling. Kind of annoying to rummage through various drawers and cabinets just to fetch the salt, sugar, maple syrup etc every time you stop. Obvious...

Re: Decimal Precision

Not directly answering your software question, but I used a flatback tape measure for my miter saw: https://www.amazon.com/FastCap-PMS-FLAT-16-Flatback-Tape-Measure/dp/B005O3AWZG.

Has inches and mm and is not too expensive to cut up. I attached it with double sided adhesive tape.

Re: Pocket and inlay issue.

This may be they reason, how much is the diameter error?
If it is, you could choose "conventional" milling direction. This will usually pull the bit (and the machine) to make pocket bigger and inserts smaller. If you do that already, there is probably another reason.

Re: 4th Axis Incomplete Finish Cut

Not sure what PP you are using but on my machine the "regular" G94 post processor (feedrate=distance/min) does not work well when cutting mostly rotation moves because the machine interpretes that as feedrate=degrees/min. If I am lucky it works but often the axis stalls because the commanded angular...

Re: Ridges in v carve

For the physical cut I’d expect that one or more of the old standbys probably apply: .............. [*]the bit doesn’t come to a sharp enough point (i.e. bit wear) a good loupe will help in inspecting the point .............. I found that bits with a rounded tip may leave less prominent waterlines....

Re: Slow feed rates on curves, fast feed rates on straight routes

The "arcs" pp will only help with circles and circular arcs, not with the free-form curves.
You could look into the g-code for a representative piece of tool path and see if that has many more lines than you have control points.

Re: Slow feed rates on curves, fast feed rates on straight routes

Probably the acceleration settings of your machine.
I don't think the Vectric software has anything to do with it.
Check the g-code and you may find there is no specific command to change the feed rate in curves.

Re: First Experience cutting 6061 Aluminum

For workholding delicate metal parts you can try fixturing wax or wax film (Mitee-Grip) . I have not tried it myself but looks promising for small parts, as long as it can be kept cool. My dust collector does not capture heavy metal chips so I take a shopvac to clean up. But aluminum or brass chips ...
