hi i did search on google for slicing software. i try to contact open source slicing program Cura. i could not get hold of software designer, only sale and maybe tech support.
i could not find slicing software where head feed -extruder feed can be set CONSTANT. second , in all slicing software that i see the max step up (z direction) distance 0.05 of inch. that is rigid. 0.05" is good for plastic but not for mig welder that i use. Yes, slicing software will be good to use , it is very close , but as they right now i can not use them. if some one know slicing software where max step up in z direction can be set up to 0.4 " and i can set extruder feed constant, let me know thank you aram On Sun, Mar 11, 2018 at 8:36 AM, Gene Heskett <ghesk...@shentel.net> wrote: > On Sunday 11 March 2018 05:54:08 Andy Pugh wrote: > > > > On 11 Mar 2018, at 06:03, a k <pccncmach...@gmail.com> wrote: > > > > > > i want reverse tool path. > > > > No, you don’t. > > > > A reversed tool path will still put the tool outside the part > > material. > > > > Just use a 3D printer slicer and configure your machine with a dummy > > extruder axis that does nothing. > > That to me, still doesn't quite get the job done.
