Um Aspirador para a Fresa! E aprendam código, uma grande Delta, Polypanels, e um Manual de encaixes!

Ora cá temos esta bela desta ideia, para começar, o vosso próprio Aspirador para toda a limalha, lixo, e serradura que a vossa Fresa CNC produza, numa grande contribuição para o asseio, a segurança...
E para a paz doméstica!

3D Printed Vacuum Cleaner for a CNC MachineNikus 

As I started to use my Dremel CNC more often I noticed that after milling wood and MDF there is a lot of thin dust everywhere around. I also faced a problem with aluminum chips that got stuck in a lead screw, so I added a cover for the lead screws but I knew that the best solution would be attaching a vacuum cleaner to the machine. I have a really big and loud workshop vacuum cleaner that is way too powerful for this task. While I was scrolling through posts in Dremel CNC builders group on Facebook I noticed Jan's post about his 3D printed vacuum cleaner. I thought that it's a really cool idea to build a small vacuum cleaner that I can put next to my CNC machine and keep it on all the time when CNC is milling. So I opened Fusion 360 at 1 AM and 2 hours later my very own 3D printed vacuum cleaner was ready to be printed. Before you will start reading this instructable you have to know that this was more of like an experiment than a project, I had no idea if it will work, I just did a quick research on the internet to find out how cyclonic separation works and how vacuum cleaner turbine looks like. But I have to say that this project exceeded my expectations a lot!

É mesmo indispensável que conheçam alguma coisa do G-Code, porque, se se meterem no maravilhoso mundo da CNC, isso vai-vos poupar muita, mas mesmo muita, dor-de-cabeça...

Por isso, aprendam no link abaixo, como!

G-Code Generator – All You Need to Know

David Pechter  

These days, computer numerical control (CNC) machines range from 3D printers to lathes, mills, and engraving machines that use lasers, plasma, or water jets. Computer control manages tool movements, spindle speed and coolant flow for CNC lathes and mills, and extrusion and bed temperatures for 3D printers. Over time, a common computer language evolved for CNC: G-code.

G-code is the not-so-secret sauce that runs a 3D printer. Based on your STL model and your settings, your slicing program decides how to make your part. It takes into account layer thickness, infill percentage, support, adhesion, extrusion, and bed temperature to generate a G-code recipe for your part, which can be understood by your printer. Each motion of the printer is given, for example, to trace the perimeter, cross-hatch, or trace interior holes. Temperature control, extrusion, and retraction are also given in G-code.

...E se quizerem fazer uma ganda Delta, sigam o exemplo deste nosso amigo, que assim, já podem fazer estátuas do cão e dos filhotes!

Brutalmente porreiro!

3D Printer the C3Dt/bd (Big Delta)

Core3D

The C3Dt/bd is my latest 3D printer design and has been turning heads at various Maker Faires and most notably at the MidWest RepRap Festival 2019. It is large and and it is accurate and most importantly, most of it's parts are off the shelf. Following are some of the features of the C3Dt/bd:

• Build Volume: 330mm(dia)x1240mm

• Board: DuetWifi (24Volt)

• Screen: Panel Due

• Delta Smart Effector

• BondTech Extruder

• Flying extruder

• Hot-end: E3D

• Auto bed Leveling

• BuildTak Flex Plate system (magnetic bed)

• Built-in bed tensioning

• Haydn Huntley’s Magball Delta arms

• Easily detachable Flying extruder

• 110volt heated bed

• 6.8mm aluminum bed

• Nema 23 stepper motors

• Unique Cable Management

• Board cooling fans

• Parts cooling fan

• 40mm fan bracket for heatsink (reduces noise)

Optional wheels in case you move it a lot

Fair warning, this is NOT a budget printer. Parts can easily run into to the thousands, but you do get one nicely working printer out of this. This being my first Delta, I was concerned about calibration and troubleshooting but I found that with the combination of parts/features above, the setup was child's play compared to some of the other printers I have designed.

E das grandes cabeças do famoso MIT, vem-nos esta Borla, da autoria da BASF, um Manual para que as vossas criações possam encaixar sem problemas, seja lá o que queiram, que  nelas encaixe...

Muito bom.

Snap-Fit Design ManualBASF 

This manual will guide you through the basics of snap-fit design, including: types of snap-fit designs and their applications; how to calculate the strength of the unit and amount of force needed for assembly; and the three common causes of failure in snap-fits and how to overcome them.
