[Emc-users] encoder

2008-07-08 Thread Terry
Hi I have an axis with 50800 counts per inch. This gives me the proper amount of travel but in the wrong direction- I am only turning the screw by hand  When I use a negative 50800 it is correct.  Will this cause me any problems or should I flip the A and B around? Thanks Terry Msg sent v

I use some Belden control cable left over from a lighting project. It's 10 or 12 conductors of 24 ga stranded wire. It doesn't melt near as bad as Cat 5 or phone wire. You might check with sound and lighting companies around town to see if they have any scraps. A 10' piece will last a good while.

I have been using CAT-5 wire to solder up perfboard circuits, but the insulation melts back. Does anyone have a favorite wire for perfboarding? -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal

I would like to display the axes positions in larger numbers, and possibly with an inch/mm toggle. I made an X position pyVCP element on the AXIS display, but it doesn't change with Touch-Off. Can anyone give my a head-start on how to make my pyVCP position match AXIS' position display? My lathe_p
