Importing STL File Problem
So i have some files I have made in Solidworks that are 3D files that I saved an as STL file. I can get them imported into ArtCam, but when I try to run the 3D toolpath it does all of the processing of the toolpath but it doesn't complete it how the file should look. There are saw teeth like marks all over the sides that should be straight and others that aren't cut out fully. The bit I'm using is a 1/4" upspiral flat bottom bit for both passes as the machine I use, a Probotix Fireball Meteor, doesn't have a bit change and I only know how to get it to do 1 bit per program as I am still new and learning CNC'ing.
Any ideas on what I can do to get this to turn out right would be greatly appreciated.
Thanks in advance,
Dan

Re: Importing STL File Problem
You could also save it as a DXF, then use lazy cam.
proper planning prevents piss poor performance

Re: Importing STL File Problem
Hello,
These saw marks are usually caused by the step over. I usually use a larger step over for roughing then take the step over on the finishing path to as little as possible (depending on how long the job would take.) If that doesn't work, i guess you are using the raster option? give the offset option a go and see what finish that gives? you could also change the angle of the raster offset and try that.
Please post your results would be interesting to know the problem.
You may also want to have a read through the machine relief guide which can be found here: http://moodle.tcaps.net/pluginfile.p...ine-relief.pdf
Just to make sure you have everything set up correctly
Cheers
George
