PrintNC - Electronics & First Cuts | part 2
HTML-код
- Опубликовано: 1 авг 2024
- Today we will wire up the PrintNC with an opensource grblhal board and make the first cuts.
The PrintNC is a high performance, DIY CNC router. It's based on a steel frame to ensure rigidity and uses 3D printed parts to make assembly easy.
The PrintNC project is in active development and community participation is highly encouraged! You can live chat on the PrintNC Discord or head to r/printnc and ask there. Answers are fast and the community is quickly growing!

That thing looks mint.
Wanna see it cut a lot more 😎
Does VISA Bob know that a 2.2kw spindle is in the wish list? 🤣🤣
Thank you !
I am still undecided if i want to go with a 800hz Gpenny Spindle, or a regular 400hz Rattm Spindle, so Visa Bob has some time to regroup 😅
@@ChristophLehner what are the advantages on a 800hz VS 400hz? 🤔
I got a 2.2kw 400hz and I like it a lot.
BTW, my machine design is similar, but built on top of a concrete base for sound dampening.
It all started with a little 3018 pro lol
This things take all my money... 🤣
@@pmsilvei the 800hz spindle has more torque in the low rpm range, so better for cutting metal, but it is more expensive....
can you elaborate on your concrete design? is it a concrete table?
@@ChristophLehner thank you for explaining dude.
Yes, the whole base is concrete, Y axis linear rails and ballscrews are attached to it. Made the mould, filled it with concrete and metal reinforcements, anchor points for mounting stuff on it, etc... Painted black 😁👍🏼
@@ChristophLehner besorgst du dir dann auch den passenden FI? Der sollte ja dann ein Typ B sein der selbst ca. 400€ kostet.
Wenn die Anlage eine Nullung als Fehlerschutz hat kann man darauf verzichten glaube ich (wenn das Gerät nicht gesteckt ist). Wenn man den FU anstecken will muss der Typ B als Zusatzschutz verbaut werden.
(Österreich... ÖNORM).
Insane work and the dude making it is very funny too🤣 as an automatician it hurt seeing loose cables in the chain. On my CNC I 3D printed some separations clips that help separating the cables inside. you place 5 or 6 of them in your chains and it will help keeping them paralels. 😉 again very nice machine !
A+ content as usual! You just opened up a whole new level of making. Looking forward to seeing what projects lie ahead. Keep up the great work!
Thanks for the kind words! Yeah it's also a steep learning curve :D
I hope i will one day catch up to your sideproject count, but man you are banging them out, like your day has 36hrs.
@@ChristophLehner Oh I'm sure! I played around with a little 2D stepper driven gantry in college. If you've never gone down that rabbit hole, there is A LOT to it.
You want to catch up to my side projects but I just want to catch up to your real project count😂
@@InheritanceMachining 🤣🤣
Turning down a bit shank to continue to build. You've got my respect!
I didn't think that was even possible...
Doubt you'll see this, but someone else might. M8 or M12 (possibly even M5 for the endstops) connectors could work well instead of Aviation connectors. They're commonly used in industrial applications and they come in solder cup, crimp-on, and screw terminal variants. They also come with up to 17 poles and you can even get them with strain relief, colour coding, and interrupted threads, etc.
the sculpt at the end is so... very true 🙂
Thanks for the 2nd part coming so soon after the 1st.
Great build, great humor and edit, loved it
Greetings from Czech republic
Amazing work! Your cnc machine is a work of art. I also really enjoy your humor. Thank you for sharing your creation.
Ich sehe das Holz aus der Hornbach Grabbelkiste. :D Und nun habe ich auch Lust, meinen LowRider zu ersetzen, der Flex in der X-Achse nervt mich etwas.
Awesome commentary and screenplay...
Love your videos! Sketches are one of the nicest parts haha
great videos, chris… i am surprised you dont have more sub’s… keep it up and you’ll get there for sure
Your approach to making video's made me subscribe within 1.5 video's.
Great videos, love the sense of humour.
Epic vid #2!!! Keep 'em coming!
Awesome job! Very jealous. I’m going to check out printNC now!
Don't do it😅 it's a blackhole in terms of money and time
Love it. 👍
I love these videos!
Criminally underrated- almost a continental SuperFastMatt or a Fingerprints garage
Love your videos, informative but really funny 😂
I really feel your pain with the Soldering connectors xD
Its amazing how few people understand the frustration of breaking a tap in a project you've spent sooo many hours on.
my kind of builder
very good
Very nice video, I am going to print my parts next week, I wonder if you can share the additional parts you designed for the print nc
That's a massive undertaking! The control box looks really well built, but almost surprised you didn't side project your way into a CNC plasma to cut your own haha
Thanks! slapping a plasma torch on top is still on my todo list.
But it's a classic egg/chicken dilemma, without the cabinet, i cant run the machine, and without running machine, i cant cut a cabinet :D
Hahahaha! TRUE!!!!!!!!!!!!!! That's probably next.
you make me laugh man, good on you, bless you
Hahah loved the repurposed crypto mining case and subtle dig
es wird immer geiler 🤩🤩🤩…and you sick
Please share the stepper motor specification.thanks
Christoph, is the spindle clamp 3D printed? And, if so, what filament material did you use? Nylon? Thank you.
Yes, it was PETG, after i crashed hard the first time, i reprinted it in PLA.
It's kinda nice to have a failsafe, since the clamp breaks before any serious damage is done
Is this a 57-step motor?
How many limit switches have you installed?
A total of 4, i use two on the y axis for autosquaring
Where did you source the mining case?
In our local craigslist pendant
Ok I have decided to descend into madness and make a print NC. What is the size of the drag chain you use ?
It's the 25x57mm one
@@ChristophLehner thank you
Hello, excuse me, what is the total consumption of the machine?
Ich habe mir für die Box gratis Metallregalböden besorgt und dann dann mit dem Lidl Plasmaschneider beim SchwiaVa ausgeschnitten.
Hey Chris I'd love some help on wiring my grblhal board if you would be willing 🙌
Hey, write me on discord, is probably easier....
What is the maximum z debth you can do?
Arround 120mm
Hah, turning down the shank.
How are those 3D printed motor mounts holding up? Dem steppers should get pretty toasty.
Until now, they are looking solid, but my longest cycle was 30mins... So i'll have to test further.
I appreciate Visa's customer service but I'm getting tired of explaining control boards to them. I have stuff to do.
How much momney did you spend in total?
Roughly 1400€ without the spindle/router since i had already a makita rt0700c.
Imo you can't really go cheaper, i bought the steel as offcuts, most of the other stuff was also second hand. Realistically you spend 1.5k without and 2k€ with a 2.2kW Spindle.
Many of us have the same fear....
I cringed when that tap broke
Also bin ich nicht der einzige Depp der manchmal billige Bohrer abdreht... 😁
Glad I'm not the only tap breaker. I hate those things...
I think i broke three M5 taps only on this Build
I've done an M3, M4 and lost an M5 I know not where so far on a mini.
Sir, please make a 4 axis cnc .with complete guide.
I was 16 year, I want to make my own CNC at the age of 17.
Sir please make 4 axis cnc , it helps me to make wonderful thing. With low cost!
🙏
😀 𝙥𝙧𝙤𝙢𝙤𝙨𝙢
that z-axis is so badly designed. you lose so much work height , it's crazy
