Comix for Crankers
Start with an apt file, end with Emc motion
Begin by opening a terminal and be familiar with where your files are located
You must have apt360, postp, and vapt installed for this to work
At the prompt, enter
apt /apt360/examples/squareTJP-1.apt | /vapt/vapt.py
I know thats a mouthful but try it & adjust for your locations & example choice
The file was processed, and appears graphically in the vapt window.
At the same time, some gcode was produced. Lets look at that.
Open your text editor, then open the file squareTJP-1.tap (in your current directory)
The extension is .tap becuz traditionally, nc machines used paper tap(e).
Run EMC2 and load the .tap file ( use 'any' in the file selector dialog )
We got a problem in the gcode. The 'post' doesnt follow the emc specs (yet).
But it's a tiny error, and we can 'hack' it by interactively asking emc what it wants.
This technique only address the 1st error that emc reports.
Here, I guessed that emc didnt like the % at the beginning, so I whack it :)
Another small problem to hack...
The program didnt have a feedrate, so lets add F50. before any coordinated motion.
( G00 doesn't need a feedrate, because it uses Rapid velocity. )
We're close to the end of the file now, so most is ok.
The end of the file is missing a conclusion, so lets add M02.
Woohoo! it's all loaded and no complaints!
and it runs! using open source cad & open source cnc
kudos to the authors of EMC and APT360!
