Digital Readout Question
<< < (5/5)
Jasonb:
I ditched the cheaper scales that were on my mill this summer and am a lot happier with the glass scales. The cheap ones would often show an error when switched on, have flat batteries and towards the end the x axis had a nasty habbit of adding 0.200" to the reading part way through a job.

One other problem I found with the remote readouts is that they have a handy magnet so you can mount them easily, the downside is that if you machine iron castings on a regular basis as I do then this magnet draws very fine iron dust inside the display box and causes problems with the readout.

I bought a 3 axis display but just the X&Y scales, will be getting the Z axis in a couple of weeks at Sandown show as I have something comming up where I want to use the Arc function to put a radius along the corner of a part. 

The other thing with the proper DRO readout is the ease of things like PCD drilling and spacing holes along a line. I don't think their is anything wrong with using a DRO, its a case of where do you draw the line - only use a traditional vernier calliper or a digital one, etc
