WHY DO I NEED THIS UPGRADE?
Well, if you're content with your mill as-is, there's really no need to quite frankly. We offer this upgrade path to aid in reducing backlash and increase the "smoothness" in motion.
If you have already performed a CNC conversion based on our plans or your own design and still use the machine for manual machining, this upgrade offers a good compromise between the stock leadscrew/bronze nut and ballscrews/ballnuts in that it's more accurate than the stock setup and does not backdrive like ballscrews do.
If you are planning on making your mill cnc-only, we recommend the ballscrew kit (coming soon). This will greatly reduce friction and allow for faster rapids.
WHAT ABOUT THE "ANTI-BACKLASH" NUTS?
There's a trade-off between friction and backlash reduction. In short, if you tighten the nut backlash screws to the point where you can't rotate the screw by hand, you may very well achieve zero backlash, but your motors and your hand won't be able to crank the handles on your mill. On the other hand, if you leave the nut loose (you'll notice play), you can really get your rapids moving fast, but you'll have severe backlash.
We would like to promise truly zero backlash, but in our testing, we were more likely to get repeatable backlash at between 0.003"-0.001". We have found this to be more of a "trial and error" method to "dial in" backlash to a point where hopefully you're happy with the performance.
Sorry, we really would like to guarantee zero backlash, but the best we can promise is that the nuts are adjustable to reduce backlash.

HOW EASY IS IT TO INSTALL?
Pretty easy! The installation takes less than 15 minutes. All you need to do is remove the two leadscrews and the y-axis mounting block and replace them!
We provide 4mm keystock unfiled so that you can better fit them to your handle for a tighter fit.
