Send it to me, I am brave supid enough >:D
Yvan256:
This file should cut four J22B and four J22N plates, using a 1/8" end mill, in 9.7mm thick material (cut through 9.950mm, requires a spoilboard underneath your material, I use this setting for 3/8" MDF) with 1mm passes, with plunging cuts (I need to re-add ramping cuts in the new code).
There's only four kinds of G-codes used in my files (G21 to set system to metric, G00 for above-material rapid moves, G01 for all cuts and G28 at the end to send the cutting head home) because my CAD needs to stay compatible with RML-1 which is more limited. All curves are converted into lines. No speed codes are used so anything you set in Mach3 or other should stay set for the whole cutting operations.
Home is assumed to be to the left/front of the material, with the zero Z being the surface of the material.
The breakaway tabs are "ramping cuts" so I'm not sure they're long enough in the current file, be careful.
Please air-cut first, make sure you're wearing eyes protection and please make a video of it. ;)

Hey Yvan,
Downloaded and ran your file. I dragged it to the desktop and tried opening it inside Mach, but it didn't see it, so I renamed it as a ".TAP" file, and it loaded fine. The aircut was a success and it behaved as expected.
I will pick up a 1/8" endmill this week and cut some material (yes, I will make a video).
It took 24min to cut a plate at normal speed and cranking the feed rate upto 300% it only took 8min (makes sense).
The program actually produces a catchy tune when the steppers are cutting the holes and turnung up the feed rate during this portion of the code was pretty cool.
Good work so far buddy...I will report later on in the week once cuttin bit is purchased :cheers:.

Thank you for the feedback.
When you say 24 minutes per plate, do you mean it would take around 3h12m to cut all eight plates included in the file? It seems incredibly long, considering my MDX-3 didn't even take three five times that long.
I'll be adding a few things, like add a dead-zone when dropping the cutting head above the material, ramping cuts, etc. They could be ready before you purchase your end mill, so once the optimizations are done I'll make a new post with an updated file.

Yes Yvan, if no changes to your file are made, it would take 3h12m to cut all 8 plates. 300% increase to feed rate is as far as Mach goes, but from my own experience with routers and MDF, I would say, I could drop cutting time from 8min by another 2 or 3 minutes and still safely cut all 8 plates. That puts a total cutting time of around 40min. How fast do you want to see them cut?
Question...where (when) is cutting speed generated? I know in Artcam express, when I select different cutting tools, before I generate code, each tool has a feed rate listed beside them (suggested rates anyway as they are user defineable).
I will wait for your optimized code and aircut a potion before cutting real wood.
