i have a question, yesterday while carving a couple of dimensional military medalions, one on the xcarve and one on the open builds lead1515, the lead doesnt seem to to circles very well i started then final cutout on these and the nxcarve just as smooth as ever but the lead seemed to be jerky and slow. both files were created in vetric vcarve one saved as .nc and the other saved as gcode and sent to then apropiate machines
in that file there are 18000+ lines of average length 0.27", though many of them are much smaller. the circle is also not particularly accurate, the previewer shows a rather kinky edge. can you tell the software that made the Gcode to output arcs instead, or at least not output lines that are shorter than bitdiam/4 ? It takes time for the controller to process each line, and if they are relatively short it takes longer to process the line than to cut the segment, and then the machine runs slow (or in other words, the 8 bit 16mhz microcontroller in the blackBox is struggling with the sheer volume of lines). to contrast it for you I have attached some Gcode from SketchUcam for a circle the same size and depth, assuming a 1/4" bit. this is only 470 lines of arc segments and will cut much smoother on any machine. (and even this segment count can be reduced, see gcode2.nc) cut it on some scrap and see for yourself.
It was 1/8 bit dia., well I guess I got som learning to do. In vetric I told it to create a boundary vector and use it for the outline. I have created circles and had it do the same. In fact every circle I have tried or cut it has acted this way
Are you using the Openbuilds post processor for Vectric? docs:software:vectric [OpenBuilds Documentation] Alex.
I have had this issue with both post processors, I’m going to run a test on Monday using both .nc and code from vetric and open builds cam
Gentlemen, This morning I ran a test and want to thank you for your help I believe I have the issue solved> I need to be sure when i save the file that I save it in open builds and not in xcarve, while most files run just fine from nc circles get lumpy and jerky, they also take more than twice as long to carve. Again thank you very much for your help.
