Re: [CAD_CAM_EDM_DRO] Bridgeport Series I verse Series II CNC Refit Candidates

That twin head machine is pretty unusual. How does it control the Z
axis? Does the Series 1 have steppers (big finned monsters) or has it
been retrofitted with servos? If it has steppers then allow for the cost
of new servos. The original steppers are slow and have an unhealthy
appetite for Geckos. By your description it probably has been
retrofitted with a different control and so will probably have servos.

Condition is important. Wear is very expensive to fix. Have a look at
the ways. Is the chrome smooth and shiny or can you still see the frosting?
