Greetings from a newby--- please help :(
« on: November 10, 2008, 07:39:12 PM »
So i bought a mill.. all types of software and man, who would have thought it would have been this difficult (ha)

anyway, I am using Meshcam to generate tool paths. When i bring them into Mach3 it says Unknown word where unary operation could beline0

I am confused.. this is the code it has produced... where am i going wrong?

You used the wrong post processor in MeshCAM. Make sure you choose the Mach2-Inch or mach2-mm post.

Lotsa stuff in there that is not G-code.  It's a mish-mash of G-code and non-G-code.  Specifically, the following words are NOT G-code:

Tool#
RAPID
LINE
FEED

MeshCAM should offer different posrt-processors to output G-code to suit different machine controllers, and there certainly should be one specifically for Mach3.

Okay, well- we have code now.. but i ran it and this thing-- uhm.. it dont know where it is.

I referenced the zeros so that they were in the bottom left of the stock.. and well.. the thing started going toward -Y rather than +y.. frustrating.... to say the least.

Do the axes move the right direction when you jog?  Are you aware that movement is based on the tool, not the work?  i.e. - moving -X will move the tool to the left, or the table to the right.  Moving -Y will move the tool towards the front of the machine, or the table towards the back of the machine.

How about posting your updated code?  Sounds like you're close...

yes, they do. They werent, but the do now. I fixed that.


The machine starts out and looks like it is doing well.. Then it Zeros, plunges (I assume this means -Z) WAY deep then starts again but in a ridiculous spot that cuts right through the section it just cut.. THEN tries to go deeper.. The whole part is only .145 thick...


I emailed the code to robert...

I will also add that i am running this on a p3 700mhz. The computer runs well, and does not seem overwhelmed by the software at all... infact, compared to the video tutorial from deepgroove.. i think its faster that what ever he was using.. (at least at opening the program)


Night one-- bummed. Hopefully, tomorrow will bring new light on it..

thanks for all your help= but i have to sleep.
