General Mach Discussion / Drill chuck reference on lathe table!!!

« on: March 10, 2020, 12:24:49 PM »

It seems with out switches on mach 3 turn you can not restart your machine and have a reference home.  I do not have a tail stock on my lathe.  So when I want to drill something I need to have something to bring back the tool post to proper x axis to be centered.

In researching switches it seems that they can be less than accurate unless you spend alot. 
This a hobby for me.  The closet thing I have been able to come up with is getting the drill post centered and making that machine cordinate x0 z0.   When I restart the machine the machine cordinates are the same as when you turned the machine off.  If I get the machine coordinates back to zero it seems to be at center.  This method requires you never change the machine coordinates.

Any ideas on best way to be able to call back the drill center?  Would home mechanical switches be OK ? 

Thanks in advance

General Mach Discussion / Mach 3 rpm readout in mach turn pro not going back to zero with no movement???

Just got Mach 3 and have been setting it up. On the lathe I got the adjustments to where the spindle rpm seems to be correct with the readout. 
The weird thing is when you turn the spindle off the rpm readout goes back to 60 to 150 never to zero.  Was watching a video and his lathe and mach 3 where doing the same thing as mine  Is this a problem or is there a fix?  Been all over the net but could not find anything.

Thanks Tom
