Fresadora CNC para PCB / PCB CNC Milling Machine

Estamos desenvolvendo uma fresadora CNC de baixo custo para fabricação de PCBs!
A ideia é criar uma solução capaz de realizar o desbaste das trilhas de cobre com monitoramento e controle via interface gráfica/web.

Estamos fazendo uma pesquisa rápida para entender as maiores dificuldades enfrentadas na prototipagem e fabricação de placas de circuito impresso.

How to extend a Y axis of small CNC to 2400 mm

I need a CNC machine to drill holes in long rectangular aluminum tubes (0.8mm wall thickness), up to 8ft / 2400mm long, with 0.7mm accuracy. The profiles are up to 2" / 5cm wide, so I don't need a huge X and Z axis. Is it viable to extend the Y axis to such long size in a low-cost CNC like 3018? I'd imagine I'll have to use something other than a lead screw for Y axis motion because such a long 8mm screw will sag under its own weight? The maximum budget is $3000.

Edit: I need the process to be fully automatic. The tubes have different size and shape, and being able to process multiple tubes by laying them next to each other would also be nice, this is why I want to use a CNC.

best budget diode laser engraver in 2026 with a coupon and is sculpfun still competitive against the newer brands?

The desktop laser engraver market has gotten crowded fast with new brands entering at aggressive price points and sculpfun has been around long enough to have a community but the question is whether the value proposition still holds against newer competitors. The power output and build quality on budget diode lasers are the two variables that determine whether you're buying a usable tool or a frustrating toy. Is the cutting depth on wood and acrylic actually sufficient for practical projects at the budget tier, and how does the frame rigidity hold up to maintain accuracy over repeated jobs?

DIY version of Nexen roller pinion system?

I did some poking around but haven't really seen anyone building a DIY version of Nexen's incredibly expensive roller pinion drive system. Is this system just not better enough to justify the complexity of trying to DIY it, compared to buying inexpensive spur gear racks and pinions, or using a GT or HTD belt drive?

I modeled up what I think is the correct rack profile and I'm going to attempt to print a sample piece of it with my resin printer which I believe should have the dimensional accuracy to make sections of pinion rack.

For context, I'm currently working on DIYing a large format CNC gantry router with 1700mm x 3700mm x 400mm travels. I plan on using some type of rack and pinion system for both X and Y, with a ballscrew on the Z axis. This roller pinion system was attractive at first because of the idea that it can handle extremely fast movement and also has zero backlash, because in theory there's always two rollers meshed with the rack teeth, on opposing teeth faces.

Scylla cnc problems

So I just got my scylla board installed up and running. Everything is connected right and powered correctly. When I get to the software side of things I have an issue I can't solve. In gSender and ugs I can type and tell my machine to move. But when I click the jog buttons nothing happens. So I know the machine can move why doesn't jog work in other programs.

Any open source drill press gantry?

Are there any diy “open source” implementation of something like this? I’d like to build this, but I’m not qualified to start from scratch and would love to follow a guide. The base plate moves in the y axis, and the screwdriver moves in the x and z axis. Thanks for the help.
