FAQs / Homming against work piece
« on: August 15, 2011, 03:24:00 PM »
Hi All,
I have been playing with Mach3 for a while now and have the homming and limit switches etc working correctly. Something that does bother me a bit is, how do I zero my CNC router against the work piece?
E.G. I have a square piece that has been cutt using a table saw and is of the correct dimentions, say 400mm x 450mm. I want to cut a circle in exactly the middle of the piece and is located "about" 50mm on the X and say about 50mm on the Y, in other words, the article is not at the homming potitions. My G Code is set according to the dimentions (400 x 450) I have and my tool table in Mach3 is preset with the tool diameter (6mm) etc.
How do I get the tool at exactly 0 on the work piece (about 50mm away from physical home) and with this I am assuming that Mach3, knowing the diameter (6mm end mill) will auto calculate a -3 offset to cater for the tool diameter?
Thanks for your help and great product!!
Kind Regards
Quentin
