Thanks guys, and yes that's exactly what I meant


I had pretty much decided on servos for that very reason but spending 3 times the amount, eats into funds that could be used to kit out other items. Still, I'd much rather spend on getting it right from the outset.


I'll definitely check out the Delta servos. Speaking of purely stepper/servo accuracy, one thing I saw but was not sure of its real world significance... with DMM, the encoder is 16bit (65,536) but max accuracy is 14bit (4000). Whatever it is, it'll probably exceed the machine's inherent precision**.

Panasonic servos are also a good choice, and I would use Panasonic over Delta

That's a misconception everyone has the 14 bit accuracy has nothing to do with the Encoder Resolution and most don't offer this spec, as it can be confusing, it referrers to the spacing of the Encoders division's and has no affect on the true 16Bit (65,536 ) PPR

Most Encoders fall into this accuracy range, unless you want to pay mega amounts of money, but this has no affect on the encoder rated resolution of 16 Bit in this case
