My Best Project...Until Now

An automatic tool changer for my CNC router was on my "I want it" list for over a year. Now it's done, and I love it!
I assume the question will come up where I got the tool changer. I bought it from Stepcraft.com

Hey Marius. What's the toolchanger used by this build? Is this a universal solution or only available for the Hammer-Spindles? EDIT: Oh, I spotted it - it's a stepcraft one. I'd love to have one of those for a standard spindle - but I guess I would have to spend the extra 400€ for the mechatron one.

@@MariusHornberger Would you mind posting your code for the big tool length probing somewhere? I have been dealing with this exact problem for some time now and your solution is brilliant. I am using a completely different controller so the code will definitely be different, but having a place to start would be amazing.

Amazing project. Little note from a dev : You didn't need to make the distinction between a big tool and a small tool. You could just always make the big tool move even for small tools. It doesn't matter for a small tool if it makes the big tool move.

[@fuzzybeverage8887]

I was thinking the same thing

[@S___________D]

Marius went swiss calibration on it haha

[@ohyou_6599]

My thought on it was if the tool changer were to fail, the large bit removal movement will throw the bit at the workpiece and damage it. Doing separate movements reduces the risk as a small bit movement will just leave the bit behind in the holder safely

[@Stevie_evie]

Yeah I thought that too. Also wondered why he didn't put a round plate that's as wide as his widest tool on top of that measuring 'button' then the tool will always push down on the plate, which in turn will depress the measuring tool

[@spambot7110]

​@@Stevie_evie i'm guessing he doesn't wanna mess with the actuator of the measuring button, since if you increase its width, you're increasing the off-axis force beyond what the designer intended (also then you'd have to figure out how to attach it)

Others might disagree, but I think they simply build the best type of a society. Japanese are very similar. Like Germans of the Far East. English and French too, but they are kinda tired of having sovereignty and self-determination, so unfortunately both of those groups are on their "way out" (not much more than a couple of hundred years).

[@gaffalover]

I just watched this video yesterday and really enjoyed it. Today I am watching the previous video with your automatic Dust shoe. On 12:50 you mentioned having trouble with the Finder Relays controlling the pneumatic valve: Now with said video about the dust shoe I saw you connected the valve directly between the relay - this is has caused premature wear on the relay contacts. When the Relay turns off and disconnects the Coil from supply, the built up magnetic field in the coil collapses and since it has no where to go induces a Voltage to itself which could reach hundreds to thousands of volts causing a spark across both of the relay contacts. These sparks burn away the plating and the contacts itself, leading to switching issues. The solution to suppress this should be a flyback diode, or VDR connected to the coil. Your new SSRs do have these (next to the NPN Transistor on the diagram), but I just friendly wanted you to know - maybe for your next upgrades... :P Source: State-certified technical engineer.

[@MariusHornberger]

Thanks for the hint!

[@peterkuhlmann426]

Hmm why don't just actuate a limit switch with the gantry and shift the tool rack via pneumatic?

[@kevlar952]

For measuring larger diameter tools, the CNC machines that I have operated (Specifically a HAAS VF-2) will rotate the tool opposite the cutting direction while offsetting to the side as you mentioned in the video at 26:12 as it approaches the probe. This method ensures that the lowest cutting surface contacts the probe and is used for the tool length offset. It will also approach the probe a second time at a slower feed to ensure an accurate measurement.

[@Subsonic-cd2en]

This is some next level engineering. Watched the whole thing because it was very interesting and well done. One note about your final test however - your before ATC cut was a one sided cut - the bit was not cutting a slot it was cutting on an edge. Your after ATC cut was cutting a deep slot. You actually expect the cut quality to be better in that scenario - the bit is essentially supported on both sides by the material leading to very little possibility of chatter. It's much more load on the spindle, but it should be a great surface finish. I have no doubt that it's much more capable now, but it wasn't an apples to apples comparison. Regardless, amazingly well done!!

[@mikeworks-woodworkingcarpe9377]

Marius, this is absolutely amazing. Out of curiosity though, for how you set up different movements for different sized bits - why not just have the tool holder move up high enough to reach the end of the holder only, then move out of the way but for all bits? As in, the movement programmed for your surfacing bit, just use that movement for all tool holder changes. I suppose the only disadvantage I can see is it taking a tad longer for standard bits.

[@MariusHornberger]

The way things are now came from the order I wrote the code. The big tool routine would work for everything

[@Infrared73]

@@MariusHornberger I was wondering the same thing. Essentially the case for the larger tools was added after the fact. I assume the trick with length is also tied into that code which makes it a bit more difficult to streamline. Not enough benefit to do it.

[@Dingbat217]

@@MariusHornberger I was wondering how the big tool routine knew when to stop probing the length of the tool when it tries to detect one of the flutes on the tool, did you tell it the min length of the tool or are they all sort of the same length so you know when to retract and look for one of the other flutes? Oh and that stop spindle and lift it above the surface routine could do both things at the same time so you could speed that up a bit too! :-)

[@DanteYewToob]

I felt that “cool…” lol We’ve all been so deep in a project that you can’t even really celebrate when it finally works because you’re exhausted and sort of irritated that it took this long to finally work… so the most excitement you can muster is “Oh.. cool.” hahaha I had that reaction recently when I changed my own tire on my motorcycle and had to align the wheel and tension the chain and everything myself with no experience, half the tools I needed and no motorcycle stand… I was bleeding, sweaty, exhausted, bruised and when I finally saw everything aligned perfectly I literally went “Oh.. nice.” and I dropped my tool on the floor and went inside for a “snap”.. that’s a snack nap.

[@justinc2633]

[@jeffoz1233]

Excellent as always!!! Just a thought: If you used the "big tool" movement in your software for "all tools", then you could simplify your tool table (where you tell the software if the tool is big or not) by not needing that attribute. All of the tool changes would now be the same. Thanks!!

If you have 3 outputs on your board, you could multiplex them (maybe?) so that way you have 3 bits you can play with = 8 possible controls.

[@Paul-rs4gd]

Cool idea, but it would only work if you only ever needed one output activated at a time. I wondered whether you could use the time dimension - essentially doing a single or double click on an output to provide two signals from each output. It's a kludge, but it might avoid a lot of mechanical complexity.

[@stevenvokoun7639]

A few years late at this point, but I had the same idea. Maybe have one output dedicated for the most important thing (Tool changer?), then multiplex the remaining 2 bits for 5 total outputs. The dust collector can use some type of latching relay so it can work with a temporary pulse, and I do not see why the movement and compressed air would ever need to trigger at the same time.

[@andrewwilliams3394]

With CNC milling/router machines their Achilles heel has always been the time it takes to do a tool change (machine has to return to zero position, do the tool change then return to the cutting position) so machine tool manufactures use travelling tool changers which move along the the machine the same as the spindle does, to avoid this problem. Being in Germany i am sure you will be familiar with Elumatic profile milling/router machines which use travelling tool changers. On a machine like yours a travelling tool changer is not necessary as the distance to travel is short and not too time consuming but on an industrial size machine in a production setting where time is money a travelling tool changer is a god send. Maybe a project for the future!! Keep up the good work, i love this type of videos, i have been a NC/CNC machinist for 55years and the advancement of technologies in that time have been staggering, where will it all end.

Brilliant project and the cut quality with the bits is amazing now - can't wait to see the control arm project. Also, while the 1:5 lever arrangement is impressive I'm just curious why you didn't go with an electromechanical version - I know you said that you had a lack of outputs on the controller but if you are moving the gantry back to change bits anyway then a simple microswitch would have lost you only a few millimetres in cutting space and you could have controlled a stepper motor or servo or air piston. That said the mechanical version that you can up with is pretty impressive and works great.

[@Zimbob2424]

What you can do for tools that are not in the tool rack is leave the last slot open, then when a tool is needed that is not there, have the program bring the tool changer back but out of the way, with the tool rack forward. then you drop the tool into the empty slot, after which you will signal the tool changer that it is there and can continue. and at that point also let it know if it is big or small.

Great work! There might be a flaw in the measurement of big tools, the cause can be seen at 27:08 - the tool might rotate due to one of the measurements, which may cause the measurement at the so far known lowest location to differ in case of a huge rotation.

[@phinok.m.628]

Nice... Not entirely sure what the small tool move is for, if the big tool move works fine for all tools. I probably would've also used the one pin you had left over to control the tool changer and tool holder movement, by signalling something to a little micro controller which controls the actual tool changer and tool holder, or something like that. Mainly cause I'd probably be too lazy to build such a complex 5 to 1 move out mechanism. :D But pretty cool project. Definitely quite satisfying to watch it change the tool.

[@gregrdodd]

Thanks

[@2Eblom]

Trumpf's toolchanger does something similar, but their software desides what tool is needed for the job, the software reads the tool specifications from a database, decides where in the tool holder the tools should be placed to achive the shortest runtime for the job. Newer models reads a barcode/QR-code that tells the machine what tool it is and the set length of it. On the older machines you have to put in the tool length manually when loading to job, it's been many years since I worked with Trumpf 500 and 6000.

You could share the dust collection control channel. You don't need dust collection when changing tools. When you want to change tools, clear the head from where the tool rack will move to, then turn off dust collection, which will also move the tool rack in reach.

[@frankclaus3775]

26:02 My initial thought was to attach a thin plate on top of the sensor and thus increase the surface so the bigger tool wouldn't miss the sensor. Of course it would only try to contact the sensor after blowing some air on the sensor to make sure it's clean. Your solution of course also works. Awesome job by the way. :)

[@tomcushing3619]

I see that this is a year old, and you've probably already thought of this, but just in case... Use the "Big Tool" subroutine as the standard. Just do it for all the tools, eliminating several lines of code. Install a plate on top of your tool measuring device that is slightly larger that your largest tool, then eliminate the "Large Tool Measuring" subroutine from the tool measuring process.

[@mytuberforyou]

I used to try to design everything like this, with a bunch of cam surfaces and fiddly mechanical adjustments that were subject to debris, drift, and misalignment. Today I would handle the extension/retraction of the tool table with either a couple of air cylinders that drove it right up to a hard stop, or servos, rather than relying on the precise position of the gantry. A single acting air cylinder can drive it to position and it can return via spring tension, and honestly a pair of cylinders and a solenoid are ultimately less expensive than dozens of hours trying to figure out kinematics and build the necessarioly precise parts.

7:56 I absolutely enjoy watching your videos. You do incredible work I can just imagine how proud your parents are. Very intelligent and smart. Did you go to college for engineering. Looking forward to see what you do next.

Wonderful work, great great video. My favorite quote from the video: "[...] I don't know how to describe it, it's amazing. Especially since it also works!"

Your mechanical solution was way more satisfying than a stand alone limit switch firing a solenoid for the pneumatic option. Well done

Dear Marius, another tech improvement would be etching (chemically or CNC) a unique vertical bar-code number on the body (shaft) of every tool, a small scanner on the moving tower could scan all the tools positions upon power up and find every tool bar-code number, a table in the software will do the rest. So no matter where you put the tools in the rack, the machine will identify them. Vertical bar code means every bar-code stripe will be all around the tool shaft, easy readable. Code39 or Code128 are good candidates and very easy to decode.

Inserting a nozzle that blows air on the tool before the new coupling to eliminate any residual dust would be a real touch of class!! Wonderful realisation, great.

the movement of the tool changer could be easily done by 2 stepper motor and 2 switches. one could be at the end of y axes to start the motor and other on the changer side to stop the motor at desired position, or it could have 2, one for each motor for perfect alignment. also big tool movement could be implemented for all tools so the movement for large tool wont need to huge, just until the y switch is off and the tool changer would be out of the way. anyway great project, i wrote this for anyone who try to build something similar

Marius, ich schaue deine Video´s fast seit deinen Angfängen. Mit diesem Video hast du dich mal wieder selbst übertroffen. In so jungen Jahren, soviel technischen Wissen und Können, echt Klasse! Gruß Markus

Your y to he first guy making tools I watched all g to he way thru your videos and copy them all Your a real Gem

[@sinotnasinotna5861]

You are just so talent with everything! I hope one day to open your big factory and be the sponsor for other great minds! KEEP UP!

You could just get a really big compressor tank, maybe one with a broken compressor and then hook up an cheapish to okay working compressor- maybe it can't keep up 1:1 with how much you use, but that's usually not a problem with enough capacity. That's what we've done- it's a huge tank but only cost 200 dollars (the thing is probably 7 feet tall, huge)- we hooked up the cheapest home depot compressor to it, took half a day filling it the first time and now you can use that thing all day without the compressor, then just top it all off when your done if you don't want the noise. Very neat project! I can't wait to build my CNC machine! Learning laser cutting/engraving first.

Solid state relays are versatile. Relays and solenoids can shock your equipment unless they have a diode across the coil. Be certain nothing will be damaged if a wire comes off and touches metal.

re: cleaning Marius, may I suggest you build a "cardboard dam" around your projects? It's like an inside-out cardboard box with the top cut off and the bottom pieces folded out to rest on the table. I've been using them for years to keep the chips at least on-the-table. The walls only need to be as tall as the "chip throw."

Ich war bisher nie ein CNC Fan - aber das ist einfach der Hammer. Gratulation zu dem tollen Projekt und dem Ergebnis
