help with mastercam for solidworks

[charlieb]

hi,

i've been trying to make solidworks for mastercam work on our multicam 3 axis router for some time now. for those of you who run routers you might be interested to learn that router rmd's are not supported. our reseller didn't mention that when we bought the seat. buyer beware, i guess i should have noticed. to be fair, our reseller, nw technical products, is pretty good otherwise. it turns out that there is an instruction sheet bouncing around cnc software tech guys for turning a mill def into a router def. ok, thanks, that's close enough, i can work with that. so i did the 33 step dance 3 or 4 times with no luck. my reseller gave it a shot and i was able to load my router disguised as a mill. nice work, nw tech. here is the problem: every time i post an nc file and run it i get an error at the router that says out of bounds by some amount. i've followed the tutorial steps to locate the part in solidworks to mastercam, but for some reason it's outputting an orign that's not matching up with my machine. x5 posts run fine. i pasted small samples below and attached full files. we are running mastercam 5x for solidworks with solidworks 2011, if i'm missing any other helpful info, please let me know. we run x5 for all of our parts now.

Do you use a user created origin (G55 on our Pacer/AXYZ) on your router? If that's the case, don't you have to specify in the code that you're using that G55 origin? I'm just throwing something out here, I'm not sure at all. Heck, our router is only a month old and I'm still trying to figure out the best way to run things on it lol

 

For example, here's a segment of code that I know works that I just ran on our router (not from MCam for SW), notice the G55 called out to be used:

 

N100 G20

i'll look into that, thanks. i guess i was wondering if there is anything obviously fatal in the sw to mcam post- maybe a clue that the conversion from router to mill didn't work properly. i've not spent any time to speak of looking at g-code and have no expertise. when i compare the good and bad posts i nothing jumps out at me. do both posts specify origins in the same place in relation to the router's origin? should i post something else to help answer this?

thanks,

charles

I'm pretty new to programming in general, but with the router, you can set multiple origins, correct? While with the mill it just reads the single set origin (I think). And I've noticed that tiny little imperfections in a post, or quirks with your controller, can cause weird things to happen even though the code reads right.
