General Mach Discussion / Different speed in material and above

« on: September 13, 2016, 06:02:26 PM »

Hi guys,

Im into aluminium engraving.  I must engrave a lots of letters (words) on big aluminium plate and some of letters are very far from each other.
My question is:

Is there any option in Mach3 where I can set up that my CNC machine go faster when it is above material and slower when it is in material ?

For example I want 1200 mm/s when my mill is into material I want to engrave and 2400 mm/s when it is above material (mill is going to another letter).
Whit that I would be able to reduce my time a  lot.

Thank you !

General Mach Discussion / Problem with round letters

« on: January 08, 2016, 07:11:46 AM »

Hi!

Im drawing in CorelDraw, than I create toolpath in ArtCAM which I use on MACH3.
Im using EndMill 2mm.

Mach 3 settings:

Velocity: 600
Acceleration: 140

My problem is that machine causes those weird errors on round letters like you can see on pictures.
Some of letters like ''D'' are perfectly shaped in the other hand there are lettery ''O'' and ''F'' with those errors.

I tryed changing velocity and acceleration  but problem stays the same.

Does anyone know how to solve this problem ?

Please help!

Thanks
