Re: incorrect dimensions when inverting x axis

good day hood,
there is nothing wrong...nor the machine nor any program
the only change while milling circles after changing X axis is that they are made counterclockwise in stead of clockwise
so with a rather dull milling tool in wood we got incorrect dimensions
we will try to ask lazycam to program the circles counterclockwise to verify (you know is is possible?)

thanks again

Sorry dont use LazyCAM but I am sure you will be able to specify climb or conventional milling.
Glad you found the problem :)

what is your best way to go from .DXF files to G code?
'specify climb or conventional milling' ?????

Depends on your budget I suppose, a lot of people use LazyCAM and I believe Rich has written a manual which should be in the user docs part of the forum.

Climb milling is when the cutter is pulling itself in the feed direction, conventional is when the cutter is pushing against the feed direction.

many thanks hood
yes the incorrect dimentions came from the same .dxf file but when changing X axis the milling changed from conventional to climb or vice versa
we got a difference of 2x 0.5mm = 1mm in multiplex (wood)
so we have to master the milling direction for critical figures. You know an easy way ????
