For a nicely done rotary table/stepper configuration see http://www.mandalaroseworks.com/product/stepper_relocation
The Phase-II rotary table (6-inch) is not bad quality and was occasionally on sale at Enco. No idea where to get one cheap now. I would love a low-profile tilting table for use with my 6-inch 4th axis. Any thoughts on the, currently out of stock, Grizzly T10221? Suggestions for a cheaper and available alternative? > -----Original Message----- > From: Gene Heskett [mailto:ghesk...@shentel.net] > Sent: Friday, May 25, 2018 12:48 PM > To: emc-users@lists.sourceforge.net > Subject: Re: [Emc-users] rotary tables, was Home switches. > > On Friday 25 May 2018 08:41:42 TERRY Christophersen wrote: > > > Table toward you and to the left is machine home. > > 4th axis on the right hand side of the table. > > This is how most machines are. > > > Which direction/angle is the motor sticking out?
