Here's our plasma steel cutting setup...
Autodesk Autocad 2018 (Design, save as DXF file) -> Airsoft Lazycam (Load DXF, add leading, get gcode) -> Mach3 (Auto calibrate motors, set home, zero and table size, load gcode, start cut)
Here's our problem...
Units are quite literally hit or miss. I'll set a rectangular cut that's 12" long and 6" deep and it will cut perfectly. Then, I'll load a washer with a 4" diameter and it'll cut it at 2.5". I'll re-calibrate everything and load the same code for the washer, and then it'll cut a 6" oval. I'll re-calibrate again, test with the rectangle and it'll cut 6" x 2.5"...
If someone could tell us what we're missing/doing wrong/not looking at, we'd greatly appreciate it as we're about to sell the whole setup!
If you're curious -->> HP laptop well equipped, geko g540, shielded wiring, only utilizing x and y cuts (nothing fancy), rail system with rollers (no belts).
