How to make a CNC milling machine from scratch

dumyyyyyy

March 10, 2023

EN: this is a CNC milling machine made from scratch, with parts from old printers(stepper motors , calibrated metal bars and tooth belts),laminate floor used as bearings cases, raw steel, cut by me , painted, etc. The power drill is a PROXXON type, about 12000 RPM(good quality, high rpm and no axial movement powered at 12v). The connection between PC and cnc is made trough parallel port, isolated with optocuplors(safety regulations) . The circuit board of cnc (the stepper controller) is made trough toner transfer method, y have used two MCU PIC16F84A and as “muscle” y have used some N-channel power MOSFET’s. No heatsink was required for them. As an improvement, y have used a low/high current system for stepper motors, they are powered at 12v 30% duty cycle in low current phase and with 12v 70% duty cycle in movement phase. That allow me not to overheat the motors when not used.The building time was about 5 months, in average 3 hours per day of work. The work bench took-me about two weeks,(made from raw steel, cut , welded and painted by me) and the computer for this CNC took me about 1 month (custom made plexiglas case) and y will present you in another video separately .

RO:Acesta este o masina de prelucrat pe comanda numerica(o freza comandata 3D de catre calculator)facuta de la 0 cu piese recuperate din imprimante vechi(motoare pas cu pas, curele dintate si tijele calibrate), parchet laminat folosit pe post de carcase de rulmenti, fier de la materiale de constructii taiat cu flexul, polizat si vopsit. Freza este un PROXXON are aproximativ 12000 de rotatii pe minut(buna calitate, fara joc axial, alimentata la 12v). Conexiunea intre calculator si CNC este facuta prin porul paralel, care este izolat complet cu optocuploare(reguli de siguranta impuse de lege). Cablajul imprimat al controllerului de motoare pas cu pas este facut prin metoda transferului de toner, am folosit 2 microcontrollere PIC16f84a pentru comanda motoarelor, iar ca “muschi” am folosit tranzistori MOSFET de canal N. Nu a fost necesara montarea lor pe radiator de racire, deoarece pierderile sunt mici,la fel si frecventa de lucru(ei functionand doar ca intrerupatoare electronice).Ca o inbunatatire, am folosit un sistem de comanda a motoarelor in trepte, cu curent mare si curent mic astfe: cand motoarele stau ele sunt alimentate la 12vf 30% factor de umplere, iar cand se rotesc, sunt comandate cu 12v 70% factor de umplere. In felul asta se previne incalzirea excesiva a motoarelor, ele fiind alimentate cu putere mare doar atunci cand este nevoie. Timpul de constructie a CNC-ului a fost de aproximativ 4 luni cu o medie de 3 ore de lucru pe zi. Masa de lucru mi-a laut 2 saptamani,(facuta din fier brut, taiat, sudat, vopsit, cu blat facut din parchet laminat ca e mai ieftin) iar calculatorul care comanda CNC-ul l-am facut cam intr-o luna,(carcasa facuta de mine din plexiglas) si acesta il voi prezenta intr-un video separat.

3D Topographical Map on Home Built CNC Router

Joe Harris

March 10, 2023

3D topographical map of (part of) the Middle East cut from Ash.

Top left is Antalya in Turkey and the Taurus mountains, then clockwise Cyprus top middle, the Mediterranean coast of Syria and Lebanon, then Israel and Jordan, the Sinai peninsula, Red Sea and finally Suez, and the Nile opening out into the Mediterranean.

This project took about 10.5 hours to cut!

Roughed with a 10mm straight cutter

then finished with a 1mm radius tapered ballnose.

How We Made A Wire EDM Machine At Home

Action BOX

March 7, 2023

DIY Wire EDM is finally a reality! This has been on our DIY CNC machine radar for quite some time, and finally we have done it. We added this attachment onto an old DIY CNC Machine. After all, it’s an extremely rigid epoxy granite CNC machine with a perfectly fine X Y Z motion system. We hope that getting a good working Wire EDM machine will help us produce better tolerance cuts in metals for our DIY homemade shop.

While this was just our first round of prototyping, we will continue to work on this DIY Wire EDM machine and turn it into a proper homemade CNC EDM Machine.

The flagship of GMT’s workholding line is the 6″ double-station cast iron vise. Weighing in at a hefty 110 lbs, this vise securely holds multiple workpieces while damping vibration and eliminating deflection.

The unique leadscrew design allows clamping of different sized workpieces. The fixed center jaw can be removed, and included hardware can be used to fix the front movable jaw, transforming the GDV into a wide-opening single station vise. In the single-station configuration, this vise has a jaw opening of 12.25″.

The hexagonal handle end of the leadscrew is recessed, allowing this vise to mounted on smaller mill tables without risk of enclosure collision. A handle socket extension is included for easy access.

The GDV-620FE comes standard with an extra large polished handle, handle extension, built-in chip guards, 11/16″ T-slot keys, and a set of four toeclamps. Each vise carries a 10-year limited warranty.

Carve a tile with the 3018 CNC router?

CNC AT Home

March 2, 2023

I was talking to a friend of mine who didn’t really understand how my CNC machines were setup. He said something about cutting a tile. That got me thinking about trying to use the 3018 Pro router on a tile to see what would happen. Check out this video to see how that works.
