Thank you very much again Jim! I know the difference between resolution and precision. The pieces I use to produce have a +/- 0.02mm tolerance and this is possible with heavy high precision milling...

Thank you for your reply Jim! What's the best precision a mini CNC router can achieve?

Hi,
This is my first post here after a long time. I'm looking for information about mini routers precision. I wonder if thess machines can work with precisions better than 0.005mm. Also which...

Hi,
I partially solved it. It seems HeeksCNC converts the original objects (imported from a .step file) to STL format temporary files and calculate paths using those files. I imported the objects...

I know this is an old thread but I'd like to know the differences from the accuracy stand point. Can a router achieve the same level of accuracy as a good router when machining plastics (i.e....

Hi,
I'm trying to use HeeksCAD/CNC for generating toolpaths and G-Codes but there's something wrong because toolpaths are below the solid surface in certain...

It seems ball cutters would give a better finishing, probably 6mm diameter should be OK. What do you think about to use or not to use layers? How many layers for going from 4mm to 0.1mm?

You're right! Acrylic seems to be OK for single reeds. In the link below you'll find an audio clip (me playing on one of my hand finished prototypes):...

Here's a different model (easier and faster to machine but maybe less effective):

What do you think about this design?
https://dl.dropboxusercontent.com/u/10755828/Reeds%20Development/vacuumtable-1.iges. (2 holes should be drilled on X:200.5mm Y:0.0mm and X=-200.5mm Y:0.0mm for...

Thank you for your reply.

Thank you very much for your advices. It seems the vacuum table is the way to go. I try it with glue and double face tape and both affected accuracy in the Z-Axis, however I didn't have any issues...

Thank you for your reply Andrew! I need to mill first and then cutout each piece. I'd love to be able to do everything with a laser cutter/engraving machine but AFAIK laser machines are not accurate...

Hi,
I need to machine pieces like the one in the picture in acrylic (PMMA, Plexiglass).

In you eperience, which would be...

Thank you for your reply. I thought the same but just wanted to know if this could be possible in the future. This video is impressive but there's no info about Z-Axis accuracy....

Hi,
This is my second post here. As all we know laser cutters/engravers improved a lot during the recent years. However, are the current laser cutters able to mill small (80mm x 20mm, height: 3mm)...

Hi,
This is my first post here. I'm working on the development of a piece which needs to be really thin (~0.3mm) at a certain point. The material I'm considering to use is polycarbonate which I'd...
