Deine Videos sind die bisher besten über die MPCNC und selbstgebaute CNCs an sich! Vielen vielen Dank dafür! Du hast mir beim Design meiner Eigenen sehr weit geholfen, indem du die wichtigsten Punkte der MPCNC angesprochen hast.
Another well done video! I've built one even smaller, ~12x8 inches and I'm really impressed with how well it can handle aluminum. I especially like your enclosure. Those chips are EVERYWHERE!!
that would be a great improvement of stiffness but i guess that's how it'll loose the point of project -see how far a well constructed printed cnc can push..
First i have to say I'm impressed how well it cuts given how light it is. Have you considered regrinding (or having it ground) the spindle taper? 0.02mm might not seem like much but compared to your feed per tooth it is. Have you tried measuring vibrations on different parts of the machine? At what frequencies do they occour? Also about stepper motors, without encoder they don't really have any torque untill the shaft is deflected from requested position. As far as i know microstepping doesn't really affect it that much. It just changes your expectations. Deflecting the shaft by 1/16th step is much easier than deflecting 1/4th of a step regardless of microstepping used.
Thanks for the good feedback. I though about regrinding, but considering how well it cuts aluminum even with that runout I think I am going to postpone it till I have to do some other maintenance like changing the bearings. There are several acceleration sensors in my drawer that just wait to be mounted onto the MPCNC ;) Yea, according to my dial indicator the movement is accurate to 10-20micron, which is equal to 1/8 - 1/4 microstepping. However I always saw microstepping as a way to make the movement smoother. (The current with 1/16 is close to a sinewave while with full steps it is a square wave). However these TMC drivers allow 1/4 with 1/256 interpolation, which should combine the advantages of both. I am going to try that, thanks.
Well done sir - I am about 30 hours away from finishing all the printed parts - but due the caronavirus all my orders are still in processing and none have shipped - ordered 3 weeks ago - see how we go
Hi! Your modifications are great! Do you still have the file for the Tube Holder angle (for The Minimal Quantity Lubrication) at the back of your centerpiece?
I initially looked at this but after thomas sanladerers experience I went with the rs-cnc32, seems to be more rigid and I’m just about to post my 1st design to thingiverse for a dust shoe that is fixed on the z axis like that for a shapeoko
PhatPizza It’s a shame that Thomas’s experience has influenced people away from the MPCNC. He didn’t follow instructions, didn’t do even a basic level of troubleshooting, and didn’t respect the license that he agreed to. Then complained like a petulant little child that nothing worked. I lost all respect for his technical opinion that day.

Hi, your project inspired me and I want to do the same. Though I just want to cut some plywood, acrylic and sheet aluminium for the time being. Any recommendations for a sub $300 USD spindle to use with this? im in south america so aliexpress would be nice.
Some of your mods are nice. Thanks for sharing! It's just... I couldn't help myself form wondering why have you made your CNC out of plastic, but a cover of nice aluminium profiles? Should it be opposite?
Ball Slide Rails....with wipers, end of swarf problem....More accurate too, more expensive yes. So is constant cleaning of those tubes and bearings...I would not have used those tubes and carriages...IMO.
How did you connect UART to your ramps board? Mine came with preinstalled resistor at UART pins underneath. (2208 with ramps 1.5) do I need to add another resistor to the TX/RX pin? Or could I just use the RX pin as I already got a resistor added by the manufacturer (bigtreetech) thanks a lot
Do you think that 600x600x75mm will be much less rigid than yours ? Thinking about making it a little bit bigger but i'm a little bit concerned about rigidity. It will be cutting aluminium, carbon fiber and sometimes some thin steel sheet.
Very nice update. I especially like the electronics enclosure. I have been having trouble with my Raspberry PI on my 3D printer. It is mounted near the printer control board. You mentioned that adding the chokes cut down on problems that you were having. Is there anything special about the units you used and besides the wires to the stepper motors, are there any other wires that you would add these to?
There’s nothing special, just regular clip on ferrites. Additionally you could also twist the wires of each phase of the stepper motors to further prevent any interference.
Good work! I had a bad experience with GX16 connectors on my stepper wire lines (bad contact spoiled many details on my CNC table). And because of MPCNC rigidity i wouldn't call it milling machine, it's better to call it router/plotter and so on. BTW, what about to make a table with a little slope to get chips in a one place, and to drop chips in container? I think plex is not good for wooden chips because of static electricity, that get chips on plex
Thanks for the feedback. So far I have only referred to the MPCNC as a router, haven't I? I think one would need quite a steep slope to overcome the friction between the chips and table and also remove all the places where they could get stuck. Not really worth the effort in my opinion. I am not doing lots of wood but you're right, static electricity is a problem. But it can be solved with compressed air ;)(thanks to the wheels I can push the CNC outside for that) .
Great work! Can you control the spindle speed from gcode on this setup? If so, was it straight forward using the RAMPS board, or did you have to do some special solution to get it working?
@@leonbrauns what about using a little servo motor to control the potentiometer for the router speed? After all, you have an Arduino Mega in front of you 😁 Just an idea 💡 I love your MPCNC, it made me decide to finally built my own ☺️ Thank you so much!
Thanks for the videos , they are perfect..really . Since I was following the design and its improvments , you have used 15mm belt to avoid stretching problem and we saw this in earlier videos but in this one I see that the pulley's width on the motor looks bigger (wider) than the belt driving on it , have you changed it back to 6mm belt ? and if so then why?
I think the spindle is most important. Using the right end mill probably comes second. I don’t think my modifications play a big role for cutting performance.
@@leonbrauns One more question, do you have any cheaper spindles that can still haul aluminum like yours for a cheaper price and possibly 120V? I've seen the Dewalt 660 cut through aluminum pretty good but you have lots of experience with this stuff.
2 Questions, if you worry about chips on the rail, why you haven't install vaccum?? the second question is, why not print part PETG for highly loaded area to prevent creep like that
A vacuum just doesn‘t get away the chips fast enough. Especially when deep slotting aluminum an air blast is pretty much the only option. PLA is stiffer than PETG which helps to increase the rigidity.
Do you use normal arduino mega or ARM 32bit mega ? Because I use ramps 1.5 + mega with TMC 2208 UART and it gives me TMC CONNECTION ERROR - can’t figure out how to connect them via UART for almost 2 months now
Brauns CNC thanks, I tried following his steps, but he is using fresh version of marlin. Did you use fresh marlin too? Or ryan’s github preconfigured versions? (If so which one please) Many thanks!
I am using the preconfigured version for Ramps with dual endstops. Setting up the TMC2208 shouldn‘t differ from the stock version, at least I can‘t remember anything special.
These cuts are incredibly impressive! I would love to know if you have had any success cutting steel plate or flat bar (3mm or greater) and what you have done which really makes your MPCNC stiff, (other than what was covered in the other videos)? I have constantly struggled with the stiffness in the z-axis in my MPCNC.
Here is a very early video of this machine cutting 4mm thick steel: ua-cam.com/video/b7sWCtK2WhM/v-deo.html There is nothing that I haven’t shown in the videos that could make any significant difference to a common MPCNC.
@@leonbrauns ooh! I must have missed that video. Thank you for your reply. your videos have been really helpful in troubleshooting my MPCNC. (like why the Arduino kept randomly crashing) Keep up the amazing work!
It heavily depends on the material and size of the parts. By leaving some extra stock and slowly getting closer to final dimensions while measuring after each pass it's possible to achieve
Thanks for the update, that solved a lot of my questions! My other questions are, the 24V powersupply you use for the drivers is 6A ? or should I get higher / would you make a detailed electronics guide? Thanks
The 24V supply is 75W (~3A). I have often read that one should choose a power supply with a current rating around the sum of all the rated currents of the stepper motors (~10A in my case). However I haven‘t had any problems with mine so far. There is already a lot of information about electronics out there, I don‘t think I could add anything useful.
Yea, thinking a bit more about this the sum of all currents makes sense for those (often small) stepper motors which can be driven by just a transistor with a constant voltage. It isn‘t applicable for pwm stepper drivers like we use on the MPCNC. The required power should rather be calculated by PhaseVoltage*PhaseCurrent*NumberOfMotors with some safety margin.
Hello, I’ve a big Triton router 2.2 hp and my question is : do you think it’s possible to build a CNC for such a big machine ? What will be the practical issues for such a big project ? Do you think that cutting aluminum is an option with this build ? Thank you for any info and directions !… My Best.
I looked to adapt a big engine on the MPCNC and it is not obvious, because of the weight ... The structure is good but not at all to support large powers ... But do like Brauns CNC, machining aluminum parts is possible with a normal version and then making, for example, a new CNC accepting large constraints.
