I have had so much pleasure from my cnc. Big thanks to all of you that helped. But yesterday was one of those days when the writing was on the wall for one project.
I turned a bowl with a wide edge and wanted to carve a pattern around the edge and a carving inside. I used one of the free 3dvector objects.
Glued the bowl to a block and fixed it to the bed. Surfaced down to the required thicknes of rim and then put in a 6mm end mill to rough out for the internal carving. Forgot to reset the zero and managed to plunge 12mm deeper than the craving was supposed to be. Got annoyed and pulled it back. Checked th file to make sure it was not a fault in that and rerun the file. Gues what i forgot to do again...........................
So finally got it roughed out and put in the only 2mm ball end i had and remembered to zero. Ran the file and the end mil broke. Oh joy. Re-did the file for 3mm ball end and completed the carving. Put in the v bit for the top carving and somehow lent on the page down and pushed the bit right through the edge of the bowl. Got myself together and started to run the edge file. Bet you cannot guess what I forgot to do? Plunged 12mm into the plate with a 12mm vbit. Finished the edge and decided that its all your fault.!! Fancy letting nutter like me loose on a cnc.
So I went to put it back up on the lathe just to blend the carved centre to the outer rim and found that I had cut the holding rebate to small. Oh well nicest firewood you can get!!
On the plus side I have cut some beautiful lithophanes in Corian, only a few holes Honest.
