Jazz, those two videos are not very informative. No data about what "Clive Analog" or AM882 digital is using for motors, power supply or anything. Also, in my opinion, milling air is pretty pointless, if you want to show speed you should run rapid passes, not milling imaginary material. Yes, you say it went from 8m/min to 15m/min so that is good, but still not really say everything about the change, other than you swapped the drivers and the new ones are probably considerably more expensive than the old ones, but which were the old ones?

Yes, I am using 5mm screws and I am not sure you are right about me being far from the speed limit. Perhaps it is possible to drive them a bit faster, but 10m/min is a very good speed, no doubt about that.



Yes, in theory the speed limit is 35m/min for my Y screw (16mm dia, fixed one end 650mm apart, 5mm pitch, 7053rpm limit) but that is just the theory with an imaginary motor and no friction, no nut and a perfect screw, no eBay products, no vibration.

I have no doubt in my mind that digital driver is better than my old analogue driver is, but it is more a question of how much better and why than "it is better because I say so". ...and yes, I knew when I bought my DQ542MA drivers that they were copy of Leadshine drivers, so nothing new there.

There is also a difference in build quality. The machine in your video looks MUCH better build than most other machines I have seen, so of course, that is a huge advantage as well, but none the less, I KNOW that most eBay and DIY machines are not as fast as mine, even if I am not into the speed race and don't care much about bragging, but it is a fact that majority of DIY and eBay machines end up in the 4-5m/min maximum speed.
