Having some issues with setting milling direction on my CNC chamfers. Using a trace operation, and when the offset is set to ‘none’ changing the milling direction with the ‘conventional’ checkbox works as expected. However as soon as I add an inside or outside offset to the trace (something I need to do for a chamfer) the milling direction checkbox has no effect on the toolpath. I included a simple chamfer in the workspace below. Clicking and unclicking “conventional’ to change milling direction, doesn’t change the path direction. With an non-zero index all trace paths are counter clockwise no matter what I specify.
The issue is not only for trace. Outline operation are often backwards, but at least they change with the ‘conventional’ checkbox. Roughing operations seem to work properly.
Hi Stewart! Thanks for the advice, I switched to version 4.3.0 and indeed now the buttons for ‘conventional’ work to change the direction on the trace milling paths with offsets. This is great, but there are still some issues. The trace with a (positive) outside offset and conventional box checked, give a path that moves in the clockwise direction. Which for the outside of a part is the climb direction, not the conventional one. Trace operations with (positive) inside offsets have the correct polarity of direction. You might want to look at the outline operation also, as it suffers from the same issue as the outside trace operation with an offset, ‘conventional’ box actually gives a climb milling direction.
I included a workspace save from 4.3.0 that shows the milling paths going in the wrong direction.
Nice! All the tool paths that I tried this afternoon on 4.3 build now have the correct milling direction. Should I keep using the 4.3 branch for this, or will this fix be transferred to the stable build?
