"I own onecnc xr2 expert with 4th axis, and featurecam 2.5d which includes 4th axis. I also owned onecnc lathe and replaced it with featurecam lathe. It seems to me onecnc is skimping on 2.5d and focusing on 3d and hoping nobody will miss the 2.5d stuff. The only
2.5d pocketing toolpath was horrible in one cnc. Want the software to change a feedrate around a corner or have a second roughing pass cut only what is needed to cut, no way! How about cut a pocket with multiple islands efficiently, not possible in one cnc. A lot of the modifications in the new version of xr3 were already in more established cam systems anyway, so if you want software that's always playing catchup to the other guys go with onecnc. It seems to me that simple stuff like the ability to handle multiple fixtures should be taken care of before moving to 3d development. I was programming most simple jobs by hand because onecnc wasn't that good at 2.5 parts which make up the majority of the work at my shop. It makes no sense to me to make a model of a 2.5d part when I can just program it and go in featurecam and get better toolpaths."This is actually just the tip of the iceberg on this crapware.
