great recap and wonderful conversion!
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! 😄
What a wonderful, if somewhat underplayed, description of your progression through the conversion and your reasons for doing it. Thank you very much for sharing this.
Thank you for your kind feedback.
With this video the price of every Maho just doubled. Great video. Keep them coming.
Thanks for the kind words.
That is a significant achievement, congratulations! Thanks for sharing!
I got a lot of advice and support from the LinuxCNC forum. Thanks for watching.
There's something incredibly satisfying with the way the machine just selects a gear and goes on to do it's job.
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 :)
There is an argument that people are ruining the stock of otherwise good machines but I think the reality is that those machines would probably have ended up in the scrap yard if someone hadn't bought them. At least someone is trying to save them when they buy them as a project.
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). :)
thank you old tony for recommending this channel
Hi and Welcome. I hope you stay and enjoy my videos.
Over the past summer of 2020 I have built a custom CNC router using GRBL firmware and it was a challenging experience. Your retrofitted MAHO is a very impressive build and I am sure it brings inspiration to us all. I also appreciated the This Old Tony comment, he did put a lot of work into his MAHO too but he had a different vision of how to control his in mind. Once again, great video and very informational.
Thanks for the feedback. Hope you are enjoying that CNC router.
Just amazing ! A great LinuxCNC conversion example. I can't imagine all the efforts you have spent on this project. Anyway a remarkable job.
Thanks for the kind words, but really it is surprisingly simple. Just a fair bit of wiring termination and making config files.
WOW! I have a lot of respect for you, and your project. I learned CNC milling on a MH400 and MH600 back in the mid-nineties. Seeing one of these retrofitted to LinuxCNC is just..wow! Great work man!
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.
Wow, I would have found that intimidating. Well done.
Thanks. I did too. But how do you eat an elephant!
Very nice machine. Great explanation and tour, well done, thanks.
Glad you enjoyed it.
Maho maho man.
They are nice machines.
... I want to be
A MAHO man! :)
This “light touch” upgrade on an already capable, but woefully outdated industrial machine really is excellent!
You’ve learnt bucket loads and got a rigid workhorse to show for your efforts, rather than over engineering an under capable alternative! A wise decision it would seem!
I look forward to seeing more.
Thanks for the nice feedback.
Man I would love one of these old machines in my shop. Love it! Awesome conversion.
It is a pretty cool machine. Thanks for watching.
Great information and well presented, satiating my need for a TOT Maho update and then some.
Thanks. Tony is making good progress, considering his retrofit is a much bigger job.
Your content is top notch!, keep up the great work.
Thanks for the positive feedback.
Respect about the work you put successfully into this project. Now you have a beautiful, capable, working CNC machine in very good condition. Excellent! Stefan
Thanks for the kind feedback, and thanks for watching.
Incredible find, perfect retrofit!
Thanks. I got a lot of help from the LinuxCNC forum.
A very efficient/cost effective upgrade to a very high quality machine. Brilliant!
I fitted my inherent laziness to change as little as possible.
I retrofit a MH 600 C with linuxcnc.
Selling the parts I didn't need from the 432 almost paid for the machine and the conversion.
I'm surprised you still have the original unused parts.
Great job and thank you for the help you gave on the Linuxcnc.org forum.
I guess I never got around to doing anything with them. Thanks for watching.
Its Great that this machine broke down very early in its life, as it seems to be very close to mint. You have the skills to pull of the electrical refit, and really end up with a near new machine. Glad to see you did not start throwing things away, and heeded professional advice. Thanks for the channel. 🇨🇦
Thanks Steve. I was really lucky with both the Maho and the Schaublin. As both have very little wear.
This is amazing. You have done a really good job with this. Thanks for sharing.
Thanks for the kind feedback.
400 denotes the travel on the x-axis in millimeters. Nice machine. I very recently bought a perfectly maintained MH 400 P. Got mine from a school in Belgium. It is equiped with a Heidenhain TNC135 control. Fact is that the Maho and Deckel machines from that period belong to the best toolmaker milling machines that ever have been built. Those german engineers knew exactly what they where doing.
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.
I'm glad you managed to make it work, very cool!
Thanks for watching.
Thank you very much for this absolutely great video. This helps a lot deciding what to buy as I want to buy a CNC mill for my home shop this winter.
Glad you liked it. Hope you make a video of you new mill.
Superb. Well done! What an achievement
Thanks. A lot of help from the LinuxCNC forum guys. They are awesome.
Awesome conversion. Probably could have made 10 episodes out of that. Best of luck!
:) Yeah, That covered about a year of playing around with it on and off. Thanks, you too.
I used this machine and other Maho's for years loved them. Real work horses. Loved programming then especially the looping function. Program a shape and use it for multiple tools
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
You totally improved this machine. You found the perfect hobby machine in perfect condition for the retrofit and thank you for putting linux on it nice job! I love everything about this machine. I respect the sentiment for keeping them original but I believe you've done that what you've removed aged poorly compared to everything else and the new stuff fits in the old spaces. Hard to match those huge servos and that lubrication system on a real machine. So jealous.
Thanks for the kinds words. It sure is a nice machine.
Great.. There goes the used CNC market... ;)
There are a lot of similar machines around. You just have to keep your feelers out. Thank for watching.
Watching further, you did.. Great job...
Thanks.
A truly impressive modernisation.
Thanks. It is a nice machine.
Insanely good job!
Thanks. Glad you like it. It is an awsome machine.
Totally awesome retrofit and repair of a vintage, industrial VMC. I was in the process of buying the bits and pieces to build a CNC milling machine myself when I stumbled onto a Denford Triton VMC for $750. The Triton was also built, primarily, as a student teaching machine or a small prototyping machine. In the case of mine, it was used by an engineering department for prototyping antennas for cell phones and tablets. I totally lucked out as my CNC was made in 2005 and has all modern controls with Omron Servos and drivers and the spindle is a Baldor motor and driver. It also has an 8 tool rotary auto tool changer. All of the ways are the square linear rail type and have heavy-duty ball screws with oil lines to all bearings. Not quite the 2 ton monster that you have but still very substantial. The only dodgy part is the main control board which, if I cant get to work with LinuxCNC, I will replace with the appropriate Mesa cards, all running in a computer very similar to the one in your panel. My control panel is laid out very similar to yours with everything well laid out and marked. Thanks for the great walkthrough and info. Your efforts are truly an inspiration for anyone contemplating building or retrofitting an older VMC.
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.
Great video! Well-paced and packed with tons of info. And for once, a non-horrible implementation of LinuxCNC UI in hardware :)
Thanks. I tried to take advantage of the Gmoccapy Interface. It is very good.
You did well to get this working using hslf of the old gear, well done!
Thanks. I could never have afforded components as expensive as the ones Maho put in, so it made sense to recycle them.
I've been reading your thread on the LinuxCNC forum. Great work and really like the content on your TH-cam channel.
For a short time I worked with the same machine, it's a high quality, rigid and precise machine.
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.
OOhhhhhhh I would love to have one, too in my shop! Best regards Nico from Nico's Projects
It is a really nice machine.
Thanks for running over your machine. That's a fine example of a great design!
I did both the conversion of a manual machine (Bridgeport) and the retro fit of a grand old CNC machine (Shizuoka). I'd agree the latter is the way to go if you are lucky enough to find one.
BTW, the singular of axes ("axe-ease") is axis (axe-iss). Of Latin origin.
Thanks. Yeah, I sound terrible and mince words when recording. Always impressed by people who can talk ittelligbly to a camera.
Wahnsinn was du da machst! Respekt! Abo ist draußen und ich freue mich auf die nächsten Videos. Weiter so!!!
Danke sehr.
Very well done sir!
Thanks for the kind feedback.
Very nice conversion!
Thanks. And thanks for watching.
@9:25 I had almost this exact conversation with my wife not long ago! I recently learned I would be the new steward of a Deckel FP4A thanks to a very generous friend, the machine is in excellent physical condition, but has issues with the controller, so likely going to be a LinuxCNC retrofit; I'm looking forward to what I will be learning in this playlist, thank you for putting it up!
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.
very good video..thanks for your time
Thanks for watching.
Woderfull machine♥️♥️ I love maho millingmachines
It is a really nice machine.
i ve got exactly the same mashine. love it.
They are a really nicely engineered machine aren't they.
Loved this!! I picked up an old chavalier 33 and am going to try an replicate your project on it!
Cool. If you drop me a line through the email address on the channelinfo page, I can send you my consolidated note from that conversion. Maybe helpful.
Great video, and a great breakdown of all the gear.
One day I'll do something similar but for now I need to get moved and my shop setup. Owning a mill that uses 30 international (s13), there is a big benefit to owning 40 or 50 int. That is that the cost of 2 30 int holders or tools, I've seen boxes of 20+ 50 int or 15+ 40 int tooling at the same price! That and if you want to run over 1" or 32mm end mills getting chucks for 30 int is almost impossible. That means that most porcupine milling cutters are out and adding through coolant is harder and much more expensive. When I CNC I'll be looking for either this or bigger.
40 Taper is probably most common, so it is cheapest.
Awesome retrofit! I wish I bought a mill which was already CNC capable and not only 1 axis at a time (like tonys). This looks so much nicer to get running. :D
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.
Excellent. Well done
Thanks for watching.
Great conversion
Thanks for watching.
Excellent!
Glad you enjoyed it.
Thanks for the inspiration! Nice work on your conversion, and I plan to review your build thread.
I have a Dynapath mill that I plan to switch over to LinuxCNC for a number of reasons, all of which you mentioned, despite the fact that it has a functional control on it currently. I like their conversational programming language but I am held back by the slightly flavored G code that it runs, and of course the lack of program memory.
I already have the exact same MESA setup that you have (sitting in a box of parts for about three years now), and I also have the same inhibitions that you mentioned - I have a functional machine, so the last thing I want to do is turn this into a dead ended project. I want to be able to go back to the existing control system until the conversion is completed, so I decided to make header boards to interface everything with the existing DBxx connectors that plug into the original controller. I think the only thing I will do differently is add on some additional MPG wheels, borrowing the genius multiple hand wheel setup idea that This Old Tony came up with.
I appreciate your contributions to the community! Thank you for sharing!
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.
Ive always loves these old mahos
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
Yay a MAHO video :)
I like how you gave a new life to the little MH400!
I love LinuxCNC too. I think the only thing left to do is to convert This Old Tony to Linux! ;)
To be honest... i had to smile when i saw the brick of aluminum you call MPG. xD
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^^
Nice work...!
Thanks for watching.
Congrats for the nice conversion
i would recommend against the 1 mm step on the jog pendant because there are 100 clicks per revolution on that wheel and that is a far distance to travel for just one revolution. in the shop i work at, all the machines have a max step per click of 0.1 mm ant that is fast enough even on the bigger machines
Thanks, good advice. I have been thinking that as well. I need to correct the engraving, but first get it connected.
Cool to see someone running LinuxCNC instead of mach3/4. Open source is so powerful.
LinuxCNC is very very good. Thanks for watching.
Hammer cooles Projekt. Ich habe diese und ähnliche oft im Web angesehen und nun in einem Praktikum die Möglichkeit, mit CNC Fräsen zu arbeiten. Die volle Bandbreite von alter Maho 400... bis zu DMG 5-Achsen. Interessant zu sehen, wie eine solche "Alte" upgegradet wird
Maho haben gewüßt wie mann eine tolle Maschine baut.
Stil a nice video.
I have a similair machine for a year now. A mikron wf 21c. Your conversion was a big inspiration for mij machine. You dit great work with the Linux . Realy nice to see how you dit it.
My machine is running now one New delta servodrives and on eding software.
. Next job is programing the gear box. But now it is running in high gear with a vfd. Keep on the good work. I like your schaupling lathe series. Nice machine to. Maybe a lathe wil be my Next project to🤩
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😁
They're good machines, except when they are fully enclosed, which my father will attest to. They have an MH 800C in a department where he works. I believe the C refers to an integrated C axis in the table which can be either program controlled or moved with a hand wheel. The reason my father doesn't like them is the fact that they put the chip conveyor right in the front of the enclosure, and it makes it so he has to climb on top of it to set up the table. The machine is right next to a wall so opening the side door to access the table from the left hand side is out of the question. These machines were available with extensive automation which could automatically switch the machine from horizontal to vertical with the press of a single button- and this would also automatically cap the spindle hole and switch the tool from the horizontal spindle to the vertical one and vice versa.
There is a thread on Practical Machinist of a guy restoring one of those high spec MH800 with tool changer chain, pallets, 5 axis etc. Way beyond what I did. Thanks for watching.
I red your topic on practical machinist some years back and nice to see you got it running, and with such "low" effort! I made a note of the pics where you are hauling the machine inside, and now laughed a bit about your wife's comments: they don't realize that bargain and lack of functionality usually are in the same package :D
I still run my 600E2 with the original 432/10 control but am always wondering if such modernization would be in order.
I've been looking for machining centers lately, but the openness (I have the same splash guards as you), horizontal spindle and versatility make it hard to let the MAHO go. Versatility in a machining center is sub par unless there is a 4th axis trunnion and/or 5 axis... Perhaps a DMU 50T with hand operated 4th and fifth, but decent ones start at 20k...
Thank you for the video!
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.
My first computer was a Phillips Adam. It had two cassette drives, 48k of ram and no floppy. I wanted the 64k upgrade so bad I could taste it. It came with MS DOS and the text based game Hitch Hiker's Guide to the Galazy. The back page of the OS manual had a form you fill out to buy Microsoft stock. The farthest I got in the game was "You're alone in the dark.". But hey! I learned to code basic.
Nice one. My first contact with a computor was a friend had a Vic-20, with 4Kb of ram.
great conversion. amazing.
i at work uses a MIKRON wf31 with heidenhain 360 ( when i am not working on the Fehlmann picomax60)
i am really pleased to use the mikron (practically a MAHO)
but i always trew the correct oil in the central oiling machanism (vogel). but at one time my boss told me that he heard from some "experts" probable himself, that i could put Mobil Vactra no2 in the Vogel. instead of the correct esso Febis K68 due the fact he could not get this anymore.
well since that moment the SH.T hits the fan. the sliderblocks of the z axis start to bulge where the oil passes true the block it's surrounded by carbon passtrue's they are growing resulting in so called "stick and slip" and makes the machine a heavy-runner resulting in allready two broken sets of tree bearings in the z-spindel bottom bracket and a new slip clutch.
and now my boss also heard from some experts (this time some real ones i guess) that it is practically irreversible by now, duh!
and since a few weeks the x axis is starting to stick also.
i have to rotate the x ballscrew a few turns by hand myself before doeing the start-up reference, or it will run to heavy resulting in unlocking the slip-clutch.
must say that my Mikron does not uses dovetalls like yours but a straight slider system.
so please insert the correct oil.!!!!!!!!!!!!!!!!!!
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.
Great job. Looking forward to see it carve metal.
There are already a few videos in this playlist of it turning metal to swarf.

what an amazing deal!
Yes, and yet it sat on Ebay.Kleinanzeiger.de (german Craigslist) for a few weeks before I bought it.
Really nice!! Only thing missing is a feed hold button on a physical switch!
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 for a really great video. Now I just have to get the balls to update my Huron J2 which has been a big paperweight for far too long!
Good one. The Hurons are serious machines.
I'm in the progress of converting a Optimum MH50 manual mill and everything you said in your comparison is so true. Converting something like a MAHO would be easier, cheaper and result in a much better machine. Unfortunately, an industrial machine is simply not an option if your workshop is located in your basement and all equipment has to be carried down a flight of stairs or two... Thanks for the video
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... :)

Wow great work.
Thanks. I couldn't have done it without the great folks on the LinuxCNC forum.
@@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!
Great stuff. Still trying to convince my Wife I need a mill.
Good luck with that.
Just tell her about all the money u "could" make while staying out of her hair
That's cool you can run a modern brain in this with just a few components. A good deal and a good job!
Thanks. I is nice iron.
Impressive!
Thanks. It is a really nice machine.
It needs one of those amazing retro cd-style coffee cup holders.
Nah, I am not a coffee addict. :)
Great content! Wish I would've found your channel earlier. I run mach3 on my home built machine. Always been curious about linux but seems a bit programming heavy. Any issues post processing from solidworks?
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.
Not so long time ago I updated a lathe with MESA 5i25 +7i76 for simple use with stepper motors, servo spindle and linear tool change. (short video in work on my channel)
The Mesa hardware is really a game changer. Extremely reliable and great LinuxCNC support.
I too love MAHO'S bro
They are well made.
@@RotarySMP everything was extremly well build in europe before getting flooded by cheap asian products
8088 thats awesome x)
I think my car keys probably have a more powerful processor.
Yo @RotarySMP
Watching videos like yours and Tony's always inspires me to spend hours daydreaming about the things that could be made with these tools but my theoretical machining often rings up against one problem: how can a CNC machine do internal splines with sharp internal corners? like on a bicycle casette sprocket?
can a fixed HSS tool be attached to mill and be used as a CNC sharper?
I'm sure there must be an answer and if love to watch a video on that.....
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.
th-cam.com/video/iZMlqXdCOLI/w-d-xo.html
damn old computers boggle my mind
the solution to "not enough computing power" was "just strap 15 of these suckers together"
It is pretty impressive how efficiently old processors were programmed. They could do a lot with very little processing power.
Recently had a MAHO MH800W sell at auction for $545. Looked at it but it was too big. Made me wanna cry
An 800 sized Maho really is a huge beast. I hope it didn't get scraped.
Great job! I am also planning to make retrofit on my Deckel PF4A which is very similar to yours, if not almost the same, but it has also ATC :) Ddid you integrate glass scales in the end with LinuxCNC?
Yes I did. Mine had Heidenhain LS-403 scales, and the Analog-Digital conversion was with a three axis EXE board. It had two dead lanes, so I used two stand alone EXE's from Ebay to interface those two channels.
Probably means its enclosed. I have a 2 car garage, with a mill lathe, and a Haas pallet changing 4axis horizontal mill. I paid about 4000 bucks plus 1200x2 for moving it twice, then had to replace the tool changer board and reprogram it. the y axis and a axis were stuck, and I still need to see if the screws need to be replaced, and the spindle probably needs to be replaced as well. in order to get it in my garage I had to remove the tool changer off the top of the column, along with everything thing else over 8 ft tall. If I put everything away in the garage I can pull the landcruiser in, then pull it out so i can open the door.
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 :)
I remember a thread on practicalmachinist where someone said, so you think you're a real machinist? When it was the last time that you have hand scraped lathe ways?
Well you did that before, just like Abom79 did, not comparing, he does his things and has his talents, you have your own as shown here, In the end I can only say, BRAVO!
Adam is a real machinist. I am aircraft mechanic. I just play a machinist on the internet :)
Thanks for the positive feedback.
Great video! Just curious how you would have hooked up the servos if you didnt have scales? Id like to try a linux retro on a mazak about the same vintage. Btw did you check the power supply before saying chuck it? But i totally agree with you that you made huge improvements over the factory 2.5d cnc.
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.
Hey @RotarySMP. Love what you did here. Also read a lot of your work on the LinuxCNC forum as I am curently busy with my own 600E retrofit. Could you possibly send me your data pack I was reading about on the forum, with all the IPC and OPC pin layouts, etc. This would save me a lot of time and effort. The MH600E seems to be the same as the MH400E wiring.
Drop me an Email though the address on the "About" tab of the channel.

awesome machine , wish I could find a good cheap cnc like that, I got a Victoria u2 horizontal mill with rotary table and universal head. I am in the middle of adding cnc to it. have already got a MASSO controler nema34 stepper motors and drivers for the conversion.
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.
Nice work. I have a Hurco km3p in about the same shape and would like to retrofit it but I am not sure where to start, I'm a manual guy.
Do you have as set of wiring diagrams? That is the most important thing. Does it currently work?
I think the problem with old used machines is the lack of support, spare parts in some cases and so on. At my work I drive 3 late 90's index lathes. They had 1 when i got there and bought 2 more used somewhere. It may take enormous amount of work to get them started and working reliably. One machine had a hard drive failure, another machine possibly had later. They got a retrofit for ssd for each machine. If you have time and interest in such things by all means do it. But a factory that is supposed to run parts I cant understand why they wont just scrap the old machines and buy new. Someone says they cost money but I ask how much does it cost to have to repair the old ones all the time. Especially when we make special stainless steels all the time. If I got the chance to do it I would start my own shop. Been looking at haas, mainly because they show the prices. 100k€ would buy me a nice mill to start with.
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.
VERY Impressive accomplishment. I’m curious as to what types of projects are planned for this machine? Is this a hobby or is it destined to be used as a job shop?
Thanks. There are a lot of really helpful guys ón the LinuxCNC forum which made it possible. This will just remain a hobby.
Good machine maho 400e
Yep. I'm happy with it. Thanks for watching.
We had this model at work. great machine, but the 600 E2 was my favorite.
Way stronger, faster and better handling...
make sure the internal battery is always charged! programming the 1000 lines of parameters is not fun.
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.
I bought a xhc-whb04b-6 pendant for around 100€. That´s an really easy way to have a pendant for linuxCNC. It works great.
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: th-cam.com/video/2eGAj-_dNoA/w-d-xo.html
Any questions? Mail me.
Wow, I can't believe the condition it's in. Do you think there's many more of these floating around the NZ training centre's? That's cheap as for here in NZ.
I live in Vienna. This mill has never been near NZ sorry. I bought it in Passau, just across the border in Bavaria.
@@RotarySMP Yes, discovered that on subsequent videos. This was your first video I've seen. Subscribed.
Hello. Great work. I have Maho 500 and want to do same project. Can you say how you connet Heidenhain ls420 liner scalse to 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.

I later found two channel of my 3 channel EXE were dead, and using two used 601D Exe from Ebay .
if those motors are servo and their electronic characteristics are know u can drive them with 3rd part drive thus interface them with 3rd parts motion controller and interface
I could. But the Indramat works, and was designed for exactly those motors, so why change it? Thanks for watching.
Inspiring. Your wife must be pleased you only have a single car garage.
You know it :)
I'm sure I'm one of many just finding you out via ToT, looking forward to watching all your content.. I have been looking into building my own pendant. Do you like your wheel? Feel, quality, repeatability.. too many options. Had a multi button mouse with wheel, total crap. Make model of the wheel? Do you like it? I'd much rather build and wire my own vs gambling on the many chinesium variants. Also, again new to your channel, looking forward to Linux cnc tips tricks folleys..
Thanks for the feedback. The jog wheel is the ebay cheapy. They feel really nice, with distinct clicks an smooth bearings. Are you using LinuxCNC with Mesa cards? I would suggest building Peter and Toms pendant. Really well designed and implemented.
