Work in a different quadrant?
« on: September 01, 2016, 04:43:45 AM »
All of my stuff up to now has been done in quadrant 1 with home at bottom left.

I have a part to make with work on both sides so the front will be in Q1 but the back will be in Q4 with home at top left.

Is there a way or setting to get the tool path display to show correct? At the moment the job is hanging off the bottom of the screen :)

Not really sure what you are meaning but I would have thought setting the XY zero position correctly for the part would do what you want.
I tend to have my CAM use lower left for zero position if it is a square/rectangular part or if it is round or has a central hole or boss then I may use that as my zero position.

Hiya,

yes i usually go bottom left but that won't work when you have to work both sides of a part and the features need to align - the bottom left becomes top left when part is flipped over :) (flipped along the X axis)

I'm just trying to get a good hold on what is going to happen when i finally get to make the parts i need, been drawing and cam'ing it in Fusion360, then reading the code, figuring out just what its doing, luckily F360 writes nice code :)

But when i load into my Mach simulator (laptop, no motion) the part is below the cross-hairs which is correct, i can drag it up but do a regen and it disappears again ;)

First thing I would say is when flipping a part it is often good to have a fixture, that can be as simple as utilising bolt holes or pockets or whatever.

I still dont get what you mean though, surely if you have lower left as zero on one side, you set the machine zero to that position and machine. You then flip the part and zero is now upper right you just rezero on the upper right corner and all should be well.

I presume the code you have for the zero being upper right has all zeros for X and Y?

Hmm, complex :)

Side two is first - it just has three counterbores, zero is top-left (Q4)
Flip horizontal - side one, zero now has to be bottom left (Q1)

X remains, Y is flipped from top to bottom.

This will only ever be a one-off and i don't normally do a fixture unless its the only way to go.

It will work just fine, its just the tool path display has to be dragged up from way down below the line :)

Toolpath should not need dragged at all.
Got a pic of the part?
