General Mach Discussion / How to import 3D files for 3dworks

« on: June 28, 2012, 12:37:14 PM »

Just getting started with the program and moving on to 3d design.. except I have no idea where to start.

Does lazy cam interpret a dxf file to 3D works for gcodes? If not, does anyone know where i would be able to find a program that translates a 2D design to 3D dimensionality?

Does AutoCad do this for me if I save it as a .DXF and then open that with lazy cam?

I did change the native units to mm to cm and then back to mm just yesterday, that might have messed it up.

The motor drive is going at 5 units per 20 mm (i just measured this out with a ruler). The mill table is 14 1/2" X 16" in size. The voltage I'm not sure about, I think it was 12V though?

Okay I have mine set at 2000 steps per rev and it is 1.8 degree stepper.

I don't know if I make any sense because I am very new at this and do not have any prior knowledge to computer programming.. but I think something maybe wrong with my hardware then because the units of my x.y.z axis are fluctuating to different numbers..

ex:

I had my gcode set to
g1 x50 ... it would go to ZeroX: +50 correlated to my table 

then after I changed my velocity of each axis selection in my "Motor Tuning and Setup" ..the zeros changed in position to the table..
what used to be programmed as g1 x50 position on the table went to ZeroX: +30 instead of ZeroX: +50

It worked! Except its getting stuck when the feed rate is set too high now.. is there a problem with my motor?

Also.. my units in my x,y,z axis keep changing randomly to different numbers than what I originally have, is it because I'm changing the velocity of my motor? Is there any way to keep that number constant so my gcodes are still correct when I work my machine? Now I have to change all my units on my gcode..

sorry, I'm such a noob.

I have a CNC mach3 mill machine running at 200mm/min.. It seems pretty slow? I'm wasn't sure because I haven't been able to program my machine any faster than what I have now.

Thanks Hood! That makes more sense. I'm able to change the speed of it now to however I want.

 Is a feedrate of 200 is the fastest?

Hi,

Getting to know the machine better!

However, now i'm trying to mess with the speed of the machine (Kernel Speed). Could someone explain to me what exactly does increasing/decreasing the feedrate actually does? Because I've changed it to F200... but the actual speed of the machine doesn't increase of decrease unless I click the (+) and (-) on my program run..

Thanks Alex this worked too!

Is there a way you can rewind the machine to make it go backwards starting from g1 x0 y-2 while changing the zaxis to -.5 increments instead of having it start over from g0 x0 y0?
