There were 2 versions of the V2E3. One had a 2 line LCD display just like the R2E3. Later ones had a 8 line LCD display. The BOSS series were designed as true CNC machines. The X travel did not exceed the saddle for better support and accuracy. Most were rigid ram.
To be competitive (cheap) the V2E3 was born followed by the V2Xt and the EZTRAK.
These filled a need and specific market. They still have the limitations of the S1STD iron. One must be aware of what one is purchasing.
A guy in Georgia (about 4 years ago) in a optical R&D shop purchased a S1STD with a .0002 DRO and complained that he could not machine to and hold .0001 inches. He could not comprehend why he could not, I gave up, and let the salesman deal with the situation he created.
Near Knoxville, TN I installed a 5 place (to the right of the decimal) Sony DRO on a die-sinking machine at a Phillips plant. I was there to 3 AM machining brackets. Next morning, they fired up the punch presses for the PC boards they were making, the floor started shaking and that last digit became irrelevant.
The very large boring mills that I assemble all use linear scales for better accuracy. This is a given but even linear scales will not get you past physical limitations of design.
