Direct link! 07/08/2010
Ive finally got a direct link from my mind to the machine. Salome is a wonderful CAD program for Linux. It may be the only one that can do 3D as far as I can tell. But it seems to be a great free solution. pyCAM turns that 3D model into a series of gcode commands. It seems to be slow for even simple shapes such as a one inch cylinder but I may be able to fix that by working with some settings. Then we have Edward Fords Processing sketch that sends the gcode one line at a time to the arduino and lastly the arduino is running grbl, which translates the gcode into steps and direction. Its all coming together. Im currently running through a set of tutorials to learn how to make objects in Salome. SInce everyone in the world loves pictures heres one of pyCAM processing that cylinder and one of the object created by the first Salome tutorial. Dont be fooled that took me forever to crank that little fish thing out. :)
pyCAM finally finished the 3 tool paths
457 seconds (7min) to process the rough path
15273 seconds (254 min or 4.24 hours) to do the semi-finish
and finally for the finishing tool path.....
21224 seconds or 353 min which turns out to be 5.9 hours.
So all in all it took 36954 seconds or 616 min or a whopping 10.26 hours! All that for a 1 inch cylinder. Wow. Make sure you dont mess that up cause it'll be another 10 hours to try again. Its the best Ive got for now but Ill be looking for alternatives unless that turns out to be a normal thing.
Couple of Pictures 07/03/2010
We've managed to get all of the motors hooked up and ready to go on my dads machine with the exception of the Z axis due to some coupling problems. That should be simple enough to fix and we made our first cuts sending one command at a time through cutecom. The last two pictures are of 4 hours of processing tool paths on my EEE pc. Not the power house of computing as you can see. Now for the pictures!!!
