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.

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.
@RotarySMP
@RotarySMP 4 года назад
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, 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.

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.

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.

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.
@RotarySMP
@RotarySMP 4 года назад
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.

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!

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.

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.

Did you have any issues tuning the servos with the scales? I did a pretty much identical swap with a Cincinnati mill. Scales, 7i77, touch screen. I love that you can retrofit them like that without cutting a wire. But after days of tuning, I haven't been able to take out overshoots at high speeds. Eventually I gave up and just ended up dropping my acceleration pretty low. Way lower than it can be. I'm debating about switching to encoders on the servos to see if that helps. You did a great clean conversion. Thanks for posting it. By the way, out of all the pendants, I like the simple Tormach Jog Shuttle Controller . You can find the non tormach rebranded one for a $20.
@RotarySMP
@RotarySMP 4 года назад
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.

Very inspirational vide you did incredible job. I have a 600e late 80s from an engineering university not many hours, was thinking of doing a conversion after seeing yours, but the thing is in working order but the parameters have dropped out (dead backup battery).

I believe those punch codes can be human decoded. I am sure it is a slow and somewhat painful business, but you should be able to get your parameters back off it. I have a print out of the constants for my 400E. Not sure how helpful they would be for you, but if you email me (check the "about" page of my channel), I can send you a scan. Since I also have the punch tape, I could scan the first couple of feet, which would give you tape and constants, so you could practice your decoding. Otherwise contact DMG.

@RotarySMP

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 wrote some python userspace code and made a PyVCP module for it which was a headache both times. Would you mind sharing the way you went about it? Cheers!

The FP42 is a solid beast isn't it. A friend who is a professional programmer wrote a linuxcnc component for me. It is all in the Github, including a flow chart of how it works, a simulator, and a full description in the wiki. github.com/jin-eld/mh400e-linuxcnc/wiki

@@RotarySMP I just stumbled across your video again and shamefully realized I never said thanks for the code. So thanks! 🙈 I've got my gear changer working on the Deckel but it's very cool to see how other people did it. Cheers!

I will be very interested to hear how you get on with the tool setter. I got one of those years ago for my linuxcnc powered desktop mill. I wired it up and got the inputs hooked up to the hal, but never really progressed beyond that, through lack of need rather than anything else. Since my spindle is an ER collet based system, all tool changes are effectively manual. I tend to break jobs up into one program per tool, giving me the opportunity to do the change. I hope to avoid this in future, having the software semi automatically set the offset using the tool setter, all from the one program. I did try and find out if this was possible, but never really got very far. What's your intended workflow? Great looking machine by the way. I hope to have the space for something like that one of these days...

I was doing the same till recently. Also havent been using the tool setter. But starting a couple of weeks ago, I started taking advantage of the 40 taper and hyd tool changing, and set up all the tools for a program in advance. I still did it with a 16mm cylinder, but am meaning to finally bring the toll setter into the work flow. Gmoccapy has an automated touch off at tool change function built in. Yeah, the Maho is a great mill. I got lucky their.

Ah sounds like I need to give Gmoccapy a look then. I have just been using axis, which at tool change locks the UI until you complete the tool change; obviously not very useful if you need to jog the machine and touch off! Thanks again...

I have a maho 1000e that i want to convert. I'm stuck at the gearbox of the spindle. Would it be wiser to replace the gearbox with a vfd?
@RotarySMP
@RotarySMP 3 года назад
Does the 1000E also have a 18 speed gearbox and a single speed 3 ph motor? A friend of mine is a professional programmer, and helped me to implement the gearbox control in LinuxCNC: github.com/jin-eld/mh400e-linuxcnc/wiki Read through this, and contact me with a PM on practical machinist (same user name) and I can supply my retrofit notes. Modern CNC machines tend to not have gearboxes, and just run a 3Ph motor and VFD. But to span the high speeds, and also the high torque at low speed, they typically have huge (30kW and up) motors.

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?
@RotarySMP
@RotarySMP 4 года назад
Thanks. There are a lot of really helpful guys ón the LinuxCNC forum which made it possible. This will just remain a hobby.

Hello RotarySMP, what was the Heidenhain controller on your MAHO 400, and if your wife have complain about the Maho I have some free room in my workshop😉👍👍
@RotarySMP
@RotarySMP 4 года назад
I wasn't a Heidenhain. It was a Phillips 432. The only Heidenhain components are the linear encoders and their A/D convertors.
