Five minute job - Modifying a chuck back plate

When you arrange your next trip to greece hit me up before coming for places and if you want to see cnc converted mahos and lathes similar to yours.

Even in an industrial setting, jumpering the e-stop is sometimes still the safer option. bypassing a particular sensor and clearing the fault in manual mode vs putting on a wrench that could crush your hand or come around and smack you when you release the brake.

[@RotarySMP]

Thanks for the feedback on that. I did a few maintenance shuts at a particle and plywood factory with my Dad while I was doing my aircraft mechanic apprenticeship, and was impressed that industrial plants are much better at worker safety than the aviation industry.

@@betaich Especially as the cooler temperatures now take away the excuse...it is too hot for casting.

[@ikbendusan]

the haimer is fairly easy to take apart. there's some springs inside that connect the gear train with the probe tip. the top of the probe (inside) has a ball that rests in a socket. i crashed mine badly and deformed the socket where it didn't contact the top of the socket immediately so it was way off. my dad bent the pin (presumably the one that holds the long spring that goes across the back of the dial mechanism) that connects the rod to the gear train to get it to read 0,005 mm under, which is fine. it's possible if you crash it even worse that it won't read at all. so either the connection to the gear train is interrupted (perhaps previous owner dropped it?) or the ball socket is damaged beyond repair

[@RotarySMP]

Thanks for the feedback I'll have to tear it down and check it out.

[@cavemaneca]

For a machine like this, usually you'd have a way to manually move an axis with the power disconnected. That way you wouldn't need to short anything in the control panel to get it moved off the hard stop. It's probably more of a pain than you'd want to go into for the Maho but it's worth keeping in mind for CNC conversions that you will eventually want to move an axis unpowered.

[@RotarySMP]

There is a hex drive on the end of each motor. I use this if I trigger the Y end stop. But Z also has a brake, so you need to take up the weight on the drive hex, and then release the motor. The MAHO was originally configured like that. I find it easier to just jumper it. This is the second time I have needed to do it.

[@vonSaufenberg]

​@@RotarySMP Like I said in my other comment this problem is common on Machines that have this layout. Hermles have a Button in the electrical cabinet that enables you to bridge the end stops and move out of it. Although you shouldn't have to manually move the axis back when you accidentally run into them during use. My Hermle has 2 end stops, one for E-Stop and one acts as a soft stop that stops all movement in that direction and will only allow you to move back out.

[@RotarySMP]

@@vonSaufenberg Linux CNC has software soft stops, but the issue is that the index marks on the linear encoders are very close to the ends of travel, so you dont need much beyond to E-Stop.

[@jFloRED]

Well it’s about goddamn time the MaHo 🤦 comes out

You went to Naxos a second time this year just to rub it in that we won't be going this year either... Oh and thanks for getting a shot of the Delos in there. We would usually be going there in a week or so... But with it being such a pain to get back to the states right now and the better halfs mom decided to have another small stroke... But thanks for putting up the clips to make me sad....

[@RotarySMP]

Sorry to hear of your MIL's stroke. Hope she recovers without permanent effects. I think most EU states have now restrictied leisure travel from the states, due to the 4th wave. I hope you can get back to Naxos next year. The people I talked to there said that the season started late, but that they had plenty of tourists from mid July till the end of august, so I hope they got enough business to get through the years.

[@theinfernalcraftsman]

@@RotarySMP Thanks. She is back at home and doing well and so far ok on her own which is amazing at 90. We have no problem getting to Greece but getting back we need a test that the US approves and just don't don't want to mess with that and a few going to greece have been spot tested and their tests got mixed up and they were quaranteened 2 weeks even though every other test was negative... We do our vacations starting in mid september. Far less people everywhere easier to non rev and a better experience. I would love to live on Naxos the weather is so much nicer. It doesn't get hot or cold there... Gotta get back there and put some cash into their economy.

Nice to see the trouble shooting stuff. Hopefully you don't have to do to much more. Great video once again.

[@RotarySMP]

Thanks. Shame I blew out the exposure on the wiring diagrams. Sorry about that.

[@Malnash014]

Just a thought on the ring light and anti-rotation bar setup, would it be worth making a custom bottle where there is a thread set in to in the head of the bolt to screw the anti-rotation bar into so you can leave the ring light attached all the time and just screw the bar in - Might be a cool 'mini' project :)

[@RotarySMP]

That is a good idea. I think the ring light wires are going to break if I keep removing it.

[@tomjagiello5119]

I think this video shows really well the prep you need when doing CNC work, it's not as simple as slap a block of steel in a vice and hit go. Also, do you ever do commission jobs? I've got a very simply ali part to cut with a couple of mounting holes and it would be perfect for the Maho 🤘

[@RotarySMP]

I don't take any commercial work, as I have neither the time (full time job, family and part time youtuber), and I dont have the skills to get work done in a sensible time frame to be able to quote a reasonable shop rate. Sorry. Thi job is for the mate who wrote the LinuxCNC software component which controls my gearbox switching. Yeah, I really notice on the manual lathe how quickly you can whip up a spacer , but how much more systematic the approach is to do things on the CNC mill.

[@vonSaufenberg]

I don't think bridging the endstops to release the E-Stop would get you thrown out because it's exactly the way Hermle dose it on the UWF series. They even have a button that you hold so you can move out of the endstop. The brake on The Z-Axis must be slipping allowing the table to slide down over time. Its a really common problem on these machines.

[@azenginerd9498]

Adding a parallel jumper button someplace (control station) sounds like a nice return on investment...

[@RotarySMP]

There is already a switch on the MAHP panel for that Axis. Good idea, maybe I can tie it into this LinuxCNC control.

[@than_vg]

Hey there, thanks for the video Regarding your spot drilling: if I am not mistaken, the idea is that the spot drill has a wider angle than the drill itself so that the drill's tip can find its way in the stop center and, well, center itself. So, spot drilling deeper than leaving just a cone defeats this purpose, as well as using a 90 deg spotting drill (if I can estimate correctly from the video, if not, please disregard this last note) BR, Thanos

[@RotarySMP]

Thanks for that input. I hadn't thought that through. I buy 90 spot drills so I can also chamfer the edge with the same tool, but it makes total sense what you are saying about using a wider spot angle than the drill point. Must remember that nexttime I buy a spot drill.

[@than_vg]

@@RotarySMP 👍 (does a 90 deg spotting drill chamfer nicely? Impressive...)

in an industrial situation whatever gets you to make more parts again is ok. Even if you have to jump some e stops. It's not but it is.

Since the bolt doesn't take much load could you drill and tap the bolt you use to hold your light and reduce the thread size of the bar for the tapping tool?

Yes, that is a good idea, as the ring light wires will sooner or later break if I keep doing this.

Nice place for holidays - I envy you :-) Good job going swiftly through the "Murphyan" hurdles, that always appear before one can start productive work.

Dumb beginners question…don’t you have issues with it being badly balanced now, shouldn’t rebalancing be done to ensure a smooth(er) rotation ?

Lathe chucks turn too slowly, and the whole system has enough mass that such minor imbalance is irrelevant.

As the sign on AVE's machines say... "THIS MACHINE WAS BUILT BEFORE SAFETY". There are no interlocks, no machine in operation lights etc. I have not disabled anything, other than temprarily jumpering that limit switch. There is no way that the MAHO complies with modern safety standards. Not interlock on the door, not PNOZ watching the E-Stop chain, no warning labels etc. I am never selling it.
