General Mach Discussion / Re: Touch probe to Point Cloud
« on: June 28, 2011, 02:42:08 AM »
Hi Mac,
The point cloud issue has been looked at by many members over the last few years and really it has all just fizzled out.
If any member has had success then he has not posted the results and full details of his project for others to follow on and develop / refine the idea further. This is all bit of a shame really but considering the mode of operation with the G31 - to get any degree of resolution the probe has to be tiny and the stepover small. Most Z axis are slow and it could easily take upwards of 12 hours to get a reasonable point cloud for even an extremely small piece of jewellery. In my opinion, with the present technology, point cloud it is just not a practical proposition for Mach3. However, there are other ideas out there and a small 'pecker' type head providing digital position may be able to increase the digitizing speed 100 fold and this could change the whole ball game.
Mach3 is quite capable of running a purpose built digitizing head but this is a solution for tomorrow not for today so unlikely to satisfy your boss, sorry.
