Hi Jim,

I think I use my mill the opposite to you - so on mine the quill feed just has some crude 1mm divisions so I use the head fine feed which has 0.05mm divisions for precision work.  So I have the dro for the position of the head and will continue to use the quill for drilling when I'm not fussy on depth.

With them being magnetic do you have to take care with mag bases?

Only had half an hour of play time in the workshop tonight but can already see the benefit of the graphical display - picture below shows using the PCD function - you can set the start and end angle and it updates the picture to show your entered parameters.  So I entered a start angle of 25 degrees and end angle of 360 degrees with 8 holes - as you work through the holes it updates the display so you can see where you are - surely much less chance of lulus!

Hi Simon

On the very rare occasions that I have used magnetic bases I can't say I noticed any interference with the mag tracks on my DRO. I would be surprised if such a thing did occur given the close proximity that the read head has to be to the track in use.
Nice display, wish I had one of those.  You will, I am sure, have realised that in your run through of the PCD function you have ended up with unevenly spaced holes because you omitted to add your offset starting angle to the final position. (or is it subtract - no matter, your lovely display will show you when you have it right  ;) ).

I do like that ability of the graphical displays but sadly it looks like my next mill won't be getting one as the machine I am looking at already has a Topaz display with Spherosyn linear encoders  :whoohoo:

All I need is to find the space for it  :slap:

You could always buy a better display than the Topaz which would take the scales ;)

Got your heart set on that one then :cartwheel:

PS Do you think I will get a finders fee

Quick at what?

And what's this about a new mill - Sexy is barely bedded in surely?

You don't want one of those, no use for through holes as there is no clearance hole in the table :LittleDevil:
