Greetings all;

Back on the 2.5.2 branch for all machines now, and I have the lathe now 
handling a G33.1 move as if the spindle was a servo, sort of.  A reversal 
of direction now synthesizes a full stop before the reversal is responded 
to.  Slow, but it works.

Two more things I want to do:
1. If I can find a spare pin on the parport, I want to auto-switch the 
braking resistors via a relay so that a much lower R is used for stopping 
from the lower speeds, a resistor safe for 1500 (spindle rpms) isn't very 
effective at 300 rpms.

2. Set up a choice of homing sequences, one for a normal, cuts on the far 
face turning tool, and one that inverts the X homing sequence for 
calibrating a boring bar.  And establishes the two different sets of 
HOME_OFFSET because a different set of contact faces on the gauge are used.

It occurs to me that some sort of dual home buttons might be generated, 
where clicking on one executes a filename associated with that button in 
order to do the actual homing moves for a normal turning tool.  Clicking on 
the other would run a different file, with reversed moves for X, and 
different HOME_OFFSETS for both because that uses a different set of 
contacts on the gauge.

As I am setup now, I have to stop LCNC, and relaunch it with a different 
.ini file just to do a boring job, a wee bit unhandy.

An added advantage would be that this homing method would allow fine tuning 
the HOME_OFFSET's by editing the loadable file, many times faster than a 
complete shutdown, edit the ini file & restarting LCNC.

Is this do-able now?  If not, perhaps it could be discussed while everybody 
is in Wichita?

Thanks.

Cheers, Gene
