Thanks for your kind words Tony.

@@RotarySMP OMG Tony is here!!!111 Thats the chance to tell him LinuxCNC is THE shit for MAHO's! ;P :D

@@surmetall5596 Tony has a lot of experience with Mach.

@@RotarySMP of course he has! But he want's full closed loop with glasscales, he just doesn't know yet. ;)

Literal first thought when watching this "I wonder if This Old Tony has seen this?"...and of course he has! 😄

Thank you for your kind feedback.

Thanks for the kind words.

I agree. It would have been a huge shame if this one were scrapped. It probably cost the same as a Mercedes in 1985, and has done very little work (won't ever wear out in my old folks home for industrial machines either). :)

They are nice machines.

... I want to be A MAHO man! :)

I got a lot of advice and support from the LinuxCNC forum. Thanks for watching.

Thanks for the kind words, but really it is surprisingly simple. Just a fair bit of wiring termination and making config files.

Thanks. I did too. But how do you eat an elephant!

Hi and Welcome. I hope you stay and enjoy my videos.

Thanks for the feedback. Hope you are enjoying that CNC router.

I got lucky there that my mate is a professional programmer, and worked with me to understand how it works, and then wrote the software. Of course I am now in for a lifetime of little milling jobs :)

Thanks for the nice feedback.

Glad you enjoyed it.

Thanks for the kind feedback, and thanks for watching.

It is a pretty cool machine. Thanks for watching.

Thanks Steve. I was really lucky with both the Maho and the Schaublin. As both have very little wear.

Thanks for the feedback. Did you also like using the Phillips 432? I have only heard postive feedback on them.

@@RotarySMP I liked it because I had nothing to compare with... 😀

@@bernhardschuepbach4533 :) I feel the same way about LinuxCNC. The only other control I ever used was TurboCNC.

Thanks. Tony is making good progress, considering his retrofit is a much bigger job.

Nice score. That is the same machine which This Old Tony has isn't it?

Yes, I believe so.

@@thatdutchtoolboy1994 Will you keep it original, or also retrofit?

I´m going to keep it original because the machine is in great condition. Near mint, I dare to say. Besides, with the Heidenhain TNC 135, you can do some very cool stuff.

@@thatdutchtoolboy1994 Good choice. I would not have retrofitted if I had any good chance of awaking the 432. Unfortunately I had no manuals for it, couldn't find them (I believe Heidenhain bought the rights to it, so they are available on the Heidenhain website under a different name) and shot gun trouble shooting with old ebay graphics modules would quickly exceed the cost of a retrofit, without any guarantee that would fit the problem.

Thanks. I got a lot of help from the LinuxCNC forum.

I fitted my inherent laziness to change as little as possible.

Thanks for the positive feedback.

I guess I never got around to doing anything with them. Thanks for watching.

Thanks for watching.

:) Yeah, That covered about a year of playing around with it on and off. Thanks, you too.

Thanks for the kind feedback.

Thanks. A lot of help from the LinuxCNC forum guys. They are awesome.

Glad you liked it. Hope you make a video of you new mill.

Thanks for the kinds words. It sure is a nice machine.

Thanks for that feedback. Shame I never got the Phillips 432 running, as I have only heard positive experience with them.

@@RotarySMP I guess some commands though are far easier on Linux CNC. E.g. for "Nuten Fräsen" (like straight holes), you have to calculate the starting point using the tools radius, but on other features you can input the middle of the feature

@@johanness6545 LinuxCNC as I have it install has not conversational programming, so I need a CAM software. There is a LinuxCNC plug in called NativeCAM which provides conversational programming. The Phillips has a great reputation for it's conversational codes doesnt it. LinuxCNC does support standard G4x tool offset codes.

@@RotarySMP Ah okay. I was talking about an old Heidenhain, which may be inferior to the Philips

Thanks for the kind feedback. I think the problem with buying a used VMC is that it is rather daunting, with a large physical presence and large uncertainty. Retrofitting is mentally easier, as it is a bunch of individual projects. The danger is that it can nickel and dime you to a huge sum of money, maybe without ever providing the performance built into the industrial machine. I look forward to your video on your Denford! Mesa Hardware is oustanding, as is the support on the LinuxCNC forum. Mesa engineers are active there.

Thanks for the feedback. I was lucky to get this with a dead controller.

@@RotarySMP yes, you got really lucky with this good lightly used example! The coincidence is that the machine I worked with was also a uni machine with little use. Too bad I couldn't buy it, it was traded in for a more modern cnc.

@@neonalon I bought this one from a Farmers son, whi had some connection with the HWK Passau. It was in Ebay.Kleinanzeignen for a few weeks.

@@RotarySMP Nice, there are some good machine deals to be found there for sure! (bought a Swiss manual mill with accessories, ex-R&D facility there for a steal,, but now I'm left wanting a CNC as well)

@@neonalon CNC mills open up a lot more creative possiblitiies. I know you can can do nearly anything manually, but the required accessories get excessive.

Thanks. I could never have afforded components as expensive as the ones Maho put in, so it made sense to recycle them.

Thanks. It is a nice machine.

Thanks.

Thanks. Yeah, I sound terrible and mince words when recording. Always impressed by people who can talk ittelligbly to a camera.

Thanks. Glad you like it. It is an awsome machine.

There are a lot of similar machines around. You just have to keep your feelers out. Thank for watching.

Thanks. I tried to take advantage of the Gmoccapy Interface. It is very good.

That is awesome! Does the FP4 A have three separate axis drives?

@@RotarySMP yeah, it can do 3D milling like helical paths and thread milling, the original owner used it for milling injection molds.

It is a really nice machine.

40 Taper is probably most common, so it is cheapest.

When I started this, I had little clue about the MAHO model designation system. I did a fair bit of trawling through practial machinist etc to work out what I was looking. It sure made the retrofit easier to not touch any of the mechanical stuff. Thanks for watching.

Thanks. And thanks for watching.

Thanks for the kind feedback.

Cool. Drop me a line through the email on my channelinfo page, and I can send you my consolidated notes.

I am glad you got something out of that. If you send me an Email (see my channel info page) I can sent your my collected notes. While not directly applicable to your Dynapath, there might be something in there of use to you.

Thanks for watching.

It is a really nice machine.

Glad you enjoyed it.

Thanks for watching.

Danke sehr.

They are a really nicely engineered machine aren't they.

Thanks for watching.

Thanks, good advice. I have been thinking that as well. I need to correct the engraving, but first get it connected.

It wasn't the most creative CAD model/tool path I came up with :) Thanks for watching.

@@surmetall5596 Yeah, you and Peter posted your awesome handwheel design just after I machined my brick. I have been tempted to just go with yours, but am too stubborn for my own good sometimes. :)

@@RotarySMP Why don't combine both options? You don't have to print the handwheel-case, just use the perfect PCB from Peter in your Brick :). You talked in your video about cables and stuff.... Peter's PCB only need a simple Cat6-Cable and you are done! It's designed for LinuxCNC its really easy to implement it.

@@surmetall5596 I am thinking about it. I already wired up the pendant for discrete wiring, but need to decide whether it is easier to finish wiring the Maho like that, or switch to Cat 6.

@@RotarySMP Haha^^

Thanks for watching.

Nice one. Are you going to modify and use the gearbox comp my mate wrote?

@@RotarySMP i think we program only 4 options. Dan we have enough options for good use of the machine. But we wil see houw easy it wil program

Do you have a VFD as well as the gearbox?

@@RotarySMP yes a 5.5 kw yaskawa vfd. . It is a dahlander motor . 2 speed. We wirered it on the 3000rpm coil. Now we can do moore than 4500 rpm on the spindel at 60 herz.. orginal its a 4000 rpm spindel. I have on my youtupe a smal film of the machine. Later i wil make a beter one😁

On mine, I have a sticker on it for 68 weight way oil, but the manual says 220 weight. Since it sits unused fo much of the time, I went with the 220 weight oil. Figuring this wont fall off the ways as fast. Not problems with it so far.

It is an awesome tool. Shame I never got to experience the Phillips 432.

@@RotarySMP yup. Yours dident work? They are next to impossible to get parts too. I avoided them when i was looking to buying a cnc mill at first but People did not recommend them because of the part shortage. I bought a old mazak mill. It did work but I never liked the mazatrol m32. But I have machined alot of parts and made alot of money 😁

@@nikolaiownz Mine was missing an enclosure door, and one came up on Ebay.de. I think they are now old enough that many get parted out, so partsso up up used.

@@RotarySMP i am looking forward to see yiu making chips on this machine. I think you made the right choice not retrofitting an cheaper mill. 👍

@@RotarySMP i just bought a brand New dmg mori cmx 1100. Oh man what a dream machine

Feed hold is a a soft key along the bottom of the screen when in the mode to run a program. As I duplicated all those soft keys with physical buttons, I have one.

Thanks. It is a really nice machine. It took me a while to work uot what to do and implement the switch to LinixCNC, but an experience industrial electrician could have probably done it in about a week.

I have been following your retrofit on the Zerspannungsbude. This is the absoute best Chinese mill retrofit every. Respect. Then again, you just need to hire these two guys when you get your MAHO... :) kzfaq.info/get/bejne/jd1zh6ed3MqooZc.html

@@RotarySMP my neighbor works for NASA doing electrical work... I need blackmail him into helping me repair an old milling machine lol

@@lxkhn The danger there is he gets grossed out by the quality of industrial wiring and redoes it from scratch :)

@@RotarySMP you are not wrong!

Good one. The Hurons are serious machines.

Yes, and yet it sat on Ebay.Kleinanzeiger.de (german Craigslist) for a few weeks before I bought it.

Nice one. My first contact with a computor was a friend had a Vic-20, with 4Kb of ram.

Good luck with that.

Land cruisers get claustrophobic if locked in an enclosed sapce (like all cars). It is much safer to keep them in their natural habitat, and save shed space for more important things, like dicking around with machines :)

Nah, I am not a coffee addict. :)

They are well made.

@@RotarySMP everything was extremly well build in europe before getting flooded by cheap asian products

As this is just a hobby for me, if the MAHO wouldn't run, it would make no difference if it took weeks to fix. I can definitely see it is a difference calculation if it has to make you money. Then again, on my mill, there were four different gremlins. - One dead EXE channel -One unreliable EXE channel - A loose or oxidised edge connector on the relay board - The dead controller graphic. Since I addressed each of these, the machine has been dependable, even if I go a month without turning it on. The advantage of a retrofit, is you really understand the machine, and can easily trouble shoot it.

An 800 sized Maho really is a huge beast. I hope it didn't get scraped.

No internal battery issues on my one anymore. The HAL and Ini files of LinuxCNC are backed up both on another computor and the cloud. Thanks for watching.

Hi and Welcome. LinuxCNC is far more powerful and flexible than Mach, but therefore requires more effort to set it up. They community is excellent with fantastic support. I have never used solidworks, but doubt there are any issues, LinuxCNC has stayed very true to the original RS-274 definition of G-Code, so it is easy to tweak posts processors for it.

I think my car keys probably have a more powerful processor.

Adam is a real machinist. I am aircraft mechanic. I just play a machinist on the internet :) Thanks for the positive feedback.

The Mesa hardware is really a game changer. Extremely reliable and great LinuxCNC support.

Yep. I'm happy with it. Thanks for watching.

I think old 80's and early 90's industrial machines come up pretty often for very low prices, especially if the controller is shot.

Do you have as set of wiring diagrams? That is the most important thing. Does it currently work?

Unfortunately, doing things the easy way doesn't seem to be my MO. :) Is there a standard linuxCNC comp to interface with it?

@@RotarySMP made a video: kzfaq.info/get/bejne/aMt3dM1exMqyn3U.html Any questions? Mail me.

I have a shaper head for the Maho. www.forum.linuxcnc.org/12-milling/33035-retrofitting-a-1986-maho-mh-700-c-in-nz?start=420#114567 I dont have a CNC rotary table (yet, will get to that sooner or later), but with my manual rotary table and the shaper head, splines are doable. You could do the shaping with the Z axis and a fixed tool in the spindle, but on a dovetail way machine like the Maho you'd wear the ways pretty fast. With a linear bearing machine I wouldn't hestitate. Did you see Blondihacks video last month on cutting key ways? I made up a simple hand lever shaping attachment for cutting keyways on the lathe, using the old mini lathe top slide. Something like this. kzfaq.info/get/bejne/n8B9n9SJyamzfH0.html

Part of the "problem" with tuning using the HALScope is you can zoom in further and further to ridiculus resolution. I initially tuned it to never exceed 1µm dynamically, which resulted in very low accel. Once I zoomed out a bit an accepted larger following errors, I was able to increase the accel about 10x. I use a contour shuttle pro for video editing, but just need to finishing wiring up the pendant for the Maho.

My overshoots are pretty bad. As in .1mm@1000mm/m. Do you happen to know what acceleration rate you ended up with in the .ini? Mine is 6 at the moment. Thanks.

You cant run this set up open loop, as the analog servo motors have no encoders or resolvers for position feedback, only tacho's to return speed to the driver. The glass scale encoders are necessary to close the position loop. You could do like TOT and replace the DC analogosservos with servos with encoders, and only close the loop back to the drivers, but then you loose the direct measurement of actually position, auotmatically comensating for belt stretch, thermal growth etc. Glass scales are not expensive, and you can input TTL signals directly into a Mesa 7i77.

I dont know the LS420. Mine had LS403, but most Heidenhain scales of output an Analog 11mA sine wave, so you need an EXE to convert the signal to TLL Square waves. I posted my wiring diagram of how I hooked up my EXE's to the 7i77. forum.linuxcnc.org/12-milling/33035-retrofitting-a-1986-maho-mh400e?start=220#101581 I later found two channel of my 3 channel EXE were dead, and using two used 601D Exe from Ebay .

THanks for that advice. I had noticed it, but didn't think of this. My old Olympus only has 30P. The new Panasonic has a wider range of frame rates. If I set it to 24P, I won't be able to use the Olympus for B roll within the enclosure etc without loosing its audio.

@@RotarySMP I am assuming you are in somewhere with a 50 hz power supply? You will find it only really noticeable under fluorescent mostly. Some edit software will allow you to throw all different frame rates in the timeline and still output at whatever FPS you need so you can mix and match. If you shoot at 24fps you might get similar strobing but less noticeable so try 25. what is the Olympus you have?

@@RotarySMP Also look in the menu of the Olympus you might see a strobe reduction or synch scan type setting possibly underneath the shutter menu with 50 Hz and 60 Hz settings.
