Operation that will allow the tool to go "outside" the material

Hi, reasonably new to all of this (15 days into the trial). I have a 50x50x~10mm Aluminum square stock that I want to take ~47x47x2mm off of, starting from a corner. Short of “lying” to the software about the workpiece size, are there any operations that will allow this? The pocket will get me close but so far all the operations won’t let me “clean up” the open edge on the two sides. I understand the risks of letting it just run off anywhere. I just finished doing an oval cutout of a rectangle, and it warned me that the tool path would go outside (just), but it completed the operation. In this case, it won’t simulate the operation. I’m certain I’ve overlooked something, but am “stuck”. TIA

hi have you tried : turning off ignore out of bounds

this is what i get with out of bounds off

Or you can add a Profile operation using Along Line.

…… Duh… no I didn’t… I’ve much more experience with Lightburn and Fiber / Diode lasers….. The thought didn’t occur to me, given that perspective…. The other PC that’s attached to the CNC must have that turned off…. Thank you!

morning

but that would over shoot by half the diameter of tool at the end of the profile and ruin the defind line, wouldn’t it as tool goes to centre of node ? correct me if wrong

it doesn’t like profile along line, I did try the others prior to posting but the same error messages.

no worries , we have all missed the basics at times, just need someone elsse to remind us

MM is so much like LB, as far as general settings go which is a huge help

yep, I just stuck my foot in the CNC waters with a Genmitsu 4040 Pro and trialing software. I think MM will be the primary choice for my early entry and familiarity with LB. The others appear to be a longer learning curve relative.

looking at your screenshot you have squares in various layer colours , is this correct or is it my eyes.

if so why is that ? are you thinking of it like LB where you have to create new box for each toolpath

They are on different layers for organization, I had imported the a DXF from Freecad was thinking through the sequences. boils down to two LOL once the this issue is solved.

to me that is def warning bells for me , as the squares may look aligned on screen they never are correctly on material and your cuts can end up not being aligned

it does take bit of getting used to after using LB

1 drawing, apply diff tool paths to same drawing

assign diff paint colours to each operation

turn them on in preview

My first project I used no layer / colors etc, it worked fine. I wasn’t actually sure what the layer function would do given how it appears to organize.
