Might want to add some movement locking switches or some sort of "dead-man" type switch to the MPG cube. I'm sure it's mostly fine, but I'd be worried if any freak vibrations on the table causing an MPG to move when it shouldn't. Or worse; something goes wrong and the cube is knocked off of the table, it hits the floor, the mpgs spin and send all the axes in random directions, your work is ruined, your tool explodes, the spindle is slammed into your vice and bends, and worse; you have to bring your router back while you spend a few months fixing the Maho.

The difference in surface finish is most likley because one of the sides is climb milling (nice side) and The other side is conventional milling. I suspect it wont go away compleatly, unfortuneatly.

That ballnut replacement @5:18... Is it me or the crunchy sound also matches up with the metal wire harness grinding against the plastic tube rings... There is also a solid ground groove from the contact grind in the plastic tube...

I think that the crunching noise on the Y axis ball screw nut is caused by a misalignment, it makes that sound only when the bearing block is going towards the machine, that causes to bend even more and to destroy the ball screw nut

Don't worry about dove tail ways unless you have to hold .001 tolerances I operated a nc bridge port in the 70s with dove tail ways. no big deal Since then I operated and maintained 14 different cnc's . 13 had box ways, and I could hold .00005 tolerance on grade 2 titanium on a Takasawa lathe . We had Mazak mills and Lathes and Yams too.The only machine with ball ways was a Swedish drill press with 54 x 72 in travel. Are you Canadian because you work in metric? I still have not changed over. The ball screw clicking could be that you do not have double ball nuts face to face preloaded apart. This eliminates any backlash and some ball nuts takes one directional load only. The ball screws were anchored at each end with double angle contact bearings . to keep the screw from flexing. We would take 2in thick 304l stainless plate clamp it on two inche copper parallels so it would not slip also to allow for the chips to clear the cut.Chips and heat are your enemy! Drill a 1in hole thru the plate and use a 1 dia x 2.25 in corncob end mill all the way thru the plate . 200 rpm and 2in of feed full depth to make this plate into a doughnut shape. Did this for 39 years. Corn cob cutters are the best,1st rule of milling always climb cut, 2nd rule of milling always climb cut, 3rd rule of milling never conventional cut Use double ball nuts face to face preloaded and double angle contact bearings at both ends of lead screw. Have a good day.

Where did you get those gas shocks? Need a pair for my 100 year old mill. The table weighs around 500 lbs at least. Needs help going up. Have to buy a 2hp motor just to move it. Got a car steering wheel on it now. The base the table rides on is huge. The table 32inch and can move 38 inch left or right because of the huge base it's on. And no the ways aren't over tightened.

Hi Old Tony, when you cutting a cycle cw the mill behaves like conversational milling because the left side cuts more material, and when cut a cycle ccw the mill is behave like climb milling because the right side cuts more material, I thing this is the reason you see different finish in the s type groove

It's hard to tell with Chinese knock-off EtherCat stuff...I've heard good things (cheap) and horror stories (had to replace after a few months, weird firmware bugs, motor bearing failures etc.). I'm sure Tony will tell us if it's breaking down over time. It's always suspicious when you see this stuff being hawked on eBay, AliExpress, etc. Hopefully it will all work great for him. Thanks for nice video!!

Weren't you having issues with the y axis essentially right after you got it? Could there be a underlying issue with the u axis that's causing the ball nut to break?

Fantastic video. A bit more on servos.. Not all of them have batteries. The reason that servo has a battery is because it has an absolute encoder (this is how it can "remember" its position through a powercycle.) Some servos, like Allen-Bradley servos, use an incremental encoder but rely on the controller to maintain reference. In the machinery I work with on a daily basis, German paper converting equipment, there are many servo-driven elements. Since they're using incremental encoders, we have reference sensors on particular parts of the machine that the controller uses to "home" an axis. I've recently started watching your videos regularly and I'm really impressed with the amount of information you're relaying to the audience. I've learned a ton from you and I really appreciate the content. I've decided it's time to get a mill myself and stop using the ones at work for home projects. Originally, I wanted to get a CNC mill but the more I watch your videos and a few others on IRitem, I think I'd be better off getting a manual mill and adding CNC capability. This video may very well have catalyzed that idea. Thanks again for the great information and the laughs!

those are tapered gibs your y axis has there those can tighten up under motion if they have some play. now they should have either one screw pushing on either side which is a system that pretty much eliminates play in the gib but most of the time, for ease of use, they have one screw that fits into a groove to push the gib in and out ant if some part of that is worn the gib has some play to tighten up under load and screw up a ball screw in one way only

gliding ways can also work in rapid back and forth motion pretty well if they're lubricated enough, which they likely are in this case. still, scraping the ways can go a long way in keeping the oil on the ways under rapid motion. don't worry about the geometry, it should be finde the way it is and just a few crossing scrapes every half an inch is enough for those chonky guideways

A bit of pointless trivia here: The "RAL" in all the color codes (like RAL6011) is also German for "Reichs-Ausschuss für Lieferbedingungen", which loosely translates to "Imperial Committee on Production Standards". It goes back to mid-1920s Germany.

I never got to work on CNC lathes, my boss's father was an expert at the factory across the road though (always envied him a little for that), though they were from a different era. That switchboard... that's the sort of thing I could see myself ripping out and replacing with something beautiful to look at.

Haha, that power cabinet needs some work my friend, you can get better quality power supplies that aren't enormous o.o (ex; Cosel PCA series, Meanwell EPS/EPP series) Oh man, cheap pvc insulation on them copper wires.. I'd have used silicone R/C wire instead, more heat resistant :O Servo motors just have a encoder for replying back the actual movement, although on your Z axis you have a belt.. those can break or move around. I suppose the same thing could happen with a coupler. Trinamic makes some great stepper drivers that can perform microsteps, as well as detect excessive friction by measuring inductance. After watching this for awhile, I think you should pull a Ave, and just buy the smallest CNC Haas with the auto probe tools. :P

Auto tune on most Allen Bradley servos cause them to buzz trying to get perfect position. Usually need to turn it down a bit to stop the noise. Few grand for that system is cheap compared to that for just one motor.
