Lol loved this video. Great job with the therapy cut scenes it completely took this to the next level and was really entertaining!

[@InheritanceMachining]

Dude the therapist segments got me rolling! Way to commit! Home built CNC tables are almost a right of passage in the maker world these days. Looking forward to the rest of the build!

I was just thinking this. I only just stumbled on this channel looking for printnc content and assumed you had at least a couple 10s of thousands of subs from your production quality and sensibility. Definitely keep at it mate.

[@bwcdevices3028]

Your note about the X axis roller face plates just saved me about 4 hours work. Thanks Buddy !

[@j.hankinson7803]

Thanks for posting. I appreciate your humour as well, nice touch. I’ve watched your PrintNC video series and was glad to see your wife appearing as your sanity check instead of that fancy therapist. This really is a great CNC to use. The rigidity is superior to much more expensive commercial machines I think. Steel = much better than aluminum extrusions. I eventually changed to closed loop stepper motors since their prices came down last year and they are much cheaper than servos. They have really improved my precision and power.

[@W4TRI_Ronny]

Instead of paying for therapy I build machines and watch KZbin! Thanks for being my Therapist! Top work!

[@ChristophLehner]

That's how we roll 😅

[@gordonh2223]

this takes 'DIY it instead of buy it for 3x the time and money' and turn it up to 11. Incredible

[@MP-mu1kw]

Your knowledge and training in machine building coupled with having access to industrial grade machines and great communication skills all your videos are a Masterclass. Many of us would like to build machines with high degree of accuracy, but to gain or have access to such machinery has become almost impossible where I find myself here in the UK. I guess the same is happening in your neck of the woods, all the smaller metal fabricators are shutting down too. Thank you so much and keep bringing us new solutions to problems.

[@keithwins]

this is fantastic, the therapy bit is hysterical. The workmanship and thoughtfulness of the build are apparent.

Your videos are hilarious. I hope you make more again, especially the 3D printing ones.

[@newmonengineering]

I built a similar contraption out of emt and 3d printed parts and a dermal tool. It engraved things pretty well, took me about a week total to design and print everything. Took another 3 days to put it all together and work out the steps per dimension. But your looks much stronger. Good job I know the work involved it making one of these things.

[@ChristophLehner]

Sounds like a MPCNC? Or did you design it also yourself?

[@newmonengineering]

@@ChristophLehner designed every connector the whole thing. I just went to home depot bought a few things and started designing, printing and assembling. I assembled the whole week. This was in 2017.

[@mariusj8542]

I know one thing for sure. I need to talk to that shrink. This is the same rabbit hole I went down. I was just helping a friend with programming some simple python code for a sensor head to a machine. I suggested nonchalantly that we could probably just 3D print som parts( never touched a 3D printer before), and just buy a a few sheets of aluminum and make some holes. Now one year later I have built 2 3D printers for ABS with enclosures for the parts, learned Fusion 360/ CAD/ CAM, and just finalizing a home build cnc machine for cutting the aluminum. Learned react framework for front end development, brushed up on c++ coding, written a custom made gcode parser, and will probably be stuck with this side project for the next 10 years. And that surface grinder you talk about, last week I just thought I needed to start sourcing some parts for building it, because you know as well as me, everybody needs a grinder.😂

[@celiturbo]

Now that you can cut some metal, all that plastic needs to go, super easy cut quality gains right there. Cant even think about the machine flexing when your screws are rubber mounted. Put a indicator free end of screws and pull 10kg on the spindle, I'll bet you find over half of your deflection. Enlarging the hardware bolting the base frame together and adding nuts inside rather than just threading into the tube, adding backing plates or large washers inside the tube would help, same on the gantry. Tight fitting bolted in plugs in the end of the gantry might reduce a little twisting. A second bearing block on the bed rails would help keep the gantry upright. Cheap granite/slate from old billiards table or counter top for a base between the frame and spoilboard would make everything way stiffer and help resist chatter even if it does deflect. If you get rid of the plastic you can then work out the resonant frequencies and take that vs number of tool flutes to know which spindle rpm to avoid or even which rpm will help to cancel it. Shocked it cuts as well as it does for all the sins in the design, interesting start that could be done with a small 3d printer and very basic hand tools though.

[@ChristophLehner]

Thanks.for.the comment, indeed i plan to upgrade the printed parts, but you know christmas is arround the corner, so i can't have any downtime 😅

[@donataso6366]

Damn, It feels like this whole thing was made about me :D Not exactly the same things (apart from me building a printnc), but the thought flow is how I live day by day, month by month, year by year. Oh yeah, I needed 15 and 20 degree wedges for knife sharpening. I'm building a CNC mill capable of milling structural steel now. And don't you dare tell me that I could easily make them from 15 mm acrylic sheet offcuts that I have by simply using a file.

[@donataso6366]

[@GGGG_3333]

Sir you earned a new sub. loved the content 👍

[@mattchristie3057]

Thanks for the wonderful series Chris. Quick question: I noticed your killer welding skills in the laptop video; did you considering welding the rails on or using welding in any parts of the assembly of the PrintNC? Wondering if it'd be a quick shortcut to bypass the repeated drilling/tapping, while also providing increased rigidity? (at an extremely marginal level)

[@ChristophLehner]

thanks! no i'd stay away from welding, it will wrap no mather what. i'd take a somewhat flat steel beam over a more solid welded connection.

[@dennisbuns]

Quality content, I'm considering on making one myself but I don't have enough space at home. Maybe I need to make a wrecking ball first... Hmm

[@mikekinney8467]

Great video. Nice build. Links to the other open source projects? I'm surprised you didn't build a shredder for your aluminum cans to melt down in the furnace to make the alum parts.

[@ChristophLehner]

Hahhaha 😂I did start out melting cans, but you get so much dross, it's more economic to cut up aluminium wheels

[@johannesobernoeder1156]

01:43 - Hold on a second! How is the connection between ball screw and frame not a structural part? Some deflection will occur underneath the bearimgs, which need to take the axial loads. Also the plastic endcaps (seen here as connection to the z-axis) are getting bent due to high load on the ball screw nut. Also I am a bit curious about the holder for the stepper motor which needs to withstand up to 3 Nm of torque. Nevertheless, I have no doubt, this design will work in wood. Also aluminum should be no problem. But you will not get the highest precision which could be achieved. Replace the plastic parts with steel or at least aluminum to stiffen out those weak points. You can even mill those parts on your own and repeat those plastic pieces. Afterwards, you will definitively notice the increased stiffness , performance and precision!

[@ChristophLehner]

you're right, the faceplates, which holds the ballnuts are a weakpoint. In the future, i plan to mill the motormounts and faceplates out of aluminium.

[@MP-mu1kw]

I would like to build one of these machines for accuracy and wondering if I should consider getting maybe 5mm thick steel tubes and ground the surfaces where the linear rails get fitted. I know you have access to industrial grade machinery but you didn't do it and your thoughts on this will be greatly appreciated. Thank you!

[@ChristophLehner]

yeah 5mm would be optimal, especially when you are able to grind it flat

[@MP-mu1kw]

@@ChristophLehner Thanks for your reply. What should I ask when asking a shop in terms of how much accuracy of grinding flatness etc.. should it be something like say 10 micron or maybe 0.01mm considering the type of RHS mild steel I am going to be using in the CNC build?

[@felderup]

for flattening the steel, a belt sander belt cut into a long strip to flattenish it, then some body filler would work fine.

[@krolewiczrafal]

Everything is fine, but the linear guides and ball screws are quite expensive. That's why I built it on linear shafts and the drive on toothed belts - it's cheaper for amateur machines and that's what we're thinking about here.

[@Ahheck01]

"And even the second page of a google search" LOL

[@nauseouscustody1440]

Awesome 👍

[@gac231]

Christoph, I concur with the comment on the humour, awesome. Seems to me you are using 2 carriages per side instead of 1 on the original design on the dual lead screw axis. Any calculation or user experience behind this decision or is is just to make sure? I always felt this could be a weakness of the Printnc but did not know whether the worry is justified.

[@ChristophLehner]

Yes, i had leftover carriages so i slapped them on there. But i havent done any real cutting, so i can't comment on Performance yet

[@faultboy]

Hi Christoph, ich weiß nicht ob du es in deinen Videos erwähnst, aber wie schließt du deine PrintNC denn ans Netz an? Reicht da ein guter 3x1,5 Schuko Stecker? Das Internet ist ja voll von "da glüht dir der Stecker in der Dose" Kommentaren bei Stromstärken Richtung den 16A. Diese werden ja schnell von einer 2,2kw Spindel und 4x 4-5A Steppern erreicht. Würde mich freuen von deiner Erfahrung zu hören, ist schwer dazu Infos in der hauptsächlich nicht deutschen Community zu finden.

[@ChristophLehner]

Hi, Die ganze printing, also stepper.spindel VFD,.PC brauchen im Betrieb unter 1kW. Also eine normale Steckdose reicht da locker

Hi Christoph Will you send me the name of your Theapeut? I think he now has the prerequisites to understand me I started out lacking some good sound for my 'older days' and found the range of speakers that appealed to me completely out of my financial reach. So yes I have also become 'obsessed' with building a CNC to manufacture the 'future' cabinets once I get to design them. When I look at the cost of CNC parts, speaker units, electronics and measuring equipment, it would have been cheaper just to buy the speakers I liked.
