In this video we will be having a closer look at the Carvera CNC machine. I initially got interested in it because the makers of the CNC claimed that it is perfect for milling PCBs at home. So I obviously had to check it out ;-) So this video is kind of like a review in which I show you all the good and bad things about the Carvera and ultimately show you whether it is truly capable of making PCBs at home. Let's get started!

I found it to be very reliable to use the laser to etch PCBs instead of trying to route them. I spray a coat of black enamel spray paint. Laser etch the circuit, then into copper etchant like the usual method. I use a cheap 200 dollar solid state laser.
@greatscottlab Рік тому
Good idea :-)
@rpavlik1 Рік тому
Yeah I was wondering if some kind of laser or optical process would give better results, though I guess if you're drilling at all you'd have more tool offsets to worry about.

It doesn't take a month for JLPCB maybe 2 weeks tops. It literally took longer for me to receive PCBs from OSHpark located in the US than it did from from JLPCB. I will say that OSHPark's silkscreen is amazing and the cheap silkscreen option at JLPCB doesn't do a great job with fine detail graphics but it's not a big deal and works perfectly fine for footprints.

That's a nice unit. A good review also. I use a cheap CNC for PCBs if I want one and also only single sided. I've learnt lots of techniques to make the cutting work well. I use Diptrace to design my boards. From there I use bitmaps for the track exports into Vectric 2D and then out to Mach3 for the cutting. I have made dozens of boards this way. Works a treat.

Honestly the software missing is more a pro than a con for me, because it means you can use absolutely any program. Having a propietary software could be the start of limiting the machine to operate exclusively with their software so you end up forcefully relying on them rather than just searching for other program to run, like already happens with some 3D printers

I see your point, but there is value in having software that's bespoke to the machine from an end-user standpoint. It just *works* out of the box. Though I also feel it should allow G-code from any source provided it's set up for the machine.
@ccricers Рік тому

Very nice. I would suggest having a look at FlatCAM for milling, especially 2 sided PCBs. Works really well and was able to get all the holes to line up etc on a 2 sided PCB as well. Best of all its free

@@MSP_TechLab yes it is , their motto is beta is always better 🤣🤣 The UI is pretty buggy to be honest, but the functionality works great for me, helps flip the gerber files around for milling the back side, even flip the holes around too so I can drill them last.

I just bought $100 worth of supplies for thermal toner transfer and ferric chloride etching. I'm still using EasyEDA to design and print the patterns to paper, but now I can produce the final PCB's myself in about an hour with drilling and via's. I used to be a CNC programmer while working through collage and would love to have a nice mill, but I'll still be doing the toner transfer method for my PCB projects. Why - because once you get the hang to it - it works! I'd say it's better then using a CNC, no matter how much they try to perfect it.

Thank you Scott for taking the time and effort to look for these potential homemade solutions to making PCBs. I am hoping that as the technology develops something like the PCB maker you reviewed a couple of years back may improve and come down in price. $4700 (before tax and shipping) isn't exactly something a hobbyist can shell out. I'm hoping that it is just like 3D printers and the price will come down. I hope you keep looking for a good solution.

That UV exposure solder mask can be used with an additional mask that you print on a transparency film and lay over the circuit so you can prevent the UV exposure to the areas you want exposed pads. The unexposed mask can then be removed with solvents (acetone I think?) and the pads exposed without the additional milling operation. The Carvera is expensive but is already a LOT cheaper than a comparable machine that has been on the market for a few years. I worked with the LPKF circuit board CNC for a while and those are a $30-60k machine. I went through the additional training classes they offered and still had issues with damage due to tool changer issues. It did produce nice boards when working right and it had decent software with good support so there is that.

I've had great results from a generic "3040" ballscrew CNC that I've upgraded in three ways: 1) I replaced the odd spindle motor they provided with a high-quality 24000 RPM 3-phase spindle. 2) I swapped out the stock steppers and moved to closed-loop stepper/servos. 3) I added a probe input so I can capture a height map of the board before I ever cut it. Oh, and I chucked the printer-port stepper driver and went with a GRBLHAL networked controller that supports a ton of I/O and 5 axis. Anyway, the results are amazingly good, and definitely solid for creating your own boards, though obviously it's not going to add vias for you.

I worked as a biomedical engineer back in the 80's and I'd setup a system that did something similar. And boy, it was a booger to use. The mill was ok in the x & y axis, but z depth was controlled by a solenoid and thumb screw. The PCB had to be perfectly flat, or else. And, as far as I knew, router bits that small weren't available. A conductive ink was applied to the thru holes, then copper was plated to the boards in a plating machine . (Keeping the chemistry right was also a pain.) Then photo resist was hot rolled on from a carrier film, followed by normal photo resist procedures. Took me many weeks to get the procedures down, and in the end, we never really used the system. Better than running a test scoring scanner when I first started working, though.

Jlpcb is pretty awesome. I had a project that needed some custom pwm controllers. So I ordered the minimum amount of boards so I have 4 of those boards in a drawer that will probably never be used again. But I always save stuff because you never know when something will break. My philosophy is to keep spares around if you can. I can’t count the number of times I’ve saved the day because I healed on to a extra component for 15 years and they were no longer available and would have required a lot of work to integrate a newer version of the item into the system and sometimes it is almost impossible to integrate the new part.

This machine looks good and the tool change will save a lot of time.
@stevebabiak6997 Рік тому
For double sided, I imagine the “registration marks” (or zero X and Y starting positions) when flipping over must be near perfect. And the drilling of holes has to hit as close to dead center as possible.

Great video! I love seeing reviews on these types of products. I would have liked more coverage on the safety features they have or haven't included for the laser engraving feature. Since they have it fully enclosed, they could have some sort of vapor filtration system, but that wasn't mentioned, so I'm not sure. I would also be curious if the lid material is rated for the frequency of their laser. There are a lot of companies adding laser engraving features to their products, but most of the time they fail to adequately account for the required safety features and I think that needs to be called out any time a review is done.
@JoranGroothengel Рік тому
Looking at the website for the Carvera, it doesn't seem to have a separate system to control laser fumes, like a fan with exhaust tube or carbon filter to create underpressure in the enclosure. The dust extraction system seems to also really be just dust extraction, no carbon filter. However, with how well the enclosure seems to close that should be quite easy to fix, either add a hole with filter or exhaust tube, or even just slap a fan with a carbon filter in there to just circulate the air within the enclosure and wait a few minutes before opening it after a job finishes. Regarding laser frequency, they sell a separate 'laser protective cover', which replaces the plexiglas cover with a solid lid with a small window in it. So the plexiglass probably isn't laser-proof. It does come with presumably proper laser goggles, but they're just the kind that's a shop safety goggle with a laser filter, not like the diving-goggle type. I'd say it's not great, but by a long shot also not the worst for laser safety. The price and complexity is a safety barrier all in its own probably, a lot better than a €300 laser engraver from aliex without any enclosure and with questionable safety goggles, and probably not even an e-stop.

@Graham_Wideman Рік тому
If by "self-soldering" you mean that the board has a built-in heater traces, then yes, it can work, but it's more of a party stunt than a way for you to avoid just using one or another straightforward method of soldering SMD components. If you're just getting started and are apprehensive about the process -- it's not actually that hard to solder components down to 0603 by hand with a soldering iron and fine-ish solder and flux pen, if you have good visibility (like a good magnifier or microscope). But it's also easy to use paste (if you get a stencil with the PCB, and even if not), and then place all the components by hand (again, magnifier/microscope), and then use some simple heating device like an old hot plate or electric frying pan, watching the solder melt by eye. That's way easier than using a layer of the board for the heater, which may or may not heat evenly, plus additional circuitry, plus you have to use low-temp solder because if you heat the PCB layer hot enough to melt ordinary solder you will burn the board.
@treelineresearch3387 Рік тому
@@Graham_Wideman I use low-temp paste (Sn42/Bi57/Ag1, mp=137C) with a stencil for my prototypes and reflow with a heat gun, it's about as easy as it gets for low to medium density designs. Mechanical performance (barring the lower melting point) is fine, I've had a dead board on my keychain for years and the component packages are wearing away faster than the solder.

Wow! That sounds great! I feel silly for having not thought of that…I keep looking every so often to see if there’s a cheap and easy way to do this. Transparencies and a UV table seem to require careful choices of materials and stuff that I’m afraid I will have to keep constantly experimenting with to get right.

Only downside is that one 100mm^2 piece of presensitized copper clad is probably going to cost more than 5 copies of a 100mm^2 from JLC or PCBWay, including shipping.

@@treelineresearch3387 You could be right - I don't know current prices, but I know this: - It is possible to get appliable photoresist, either in a spray bottle or as a film you apply. Great if you have a stack of bare Cu boards. - It is faster than waiting for a PCB manufacturer to produce and shipping time can be *long* especially if you're in a rush - You keep your design private

@@EgonSorensen Yeah I can see corporations/consultancies wanting to keep stuff in-house for quicker turnaround and higher security, but just not really a concern for me most of the time, especially given how much postprocessing a fab-at-home board already requires even with presensitized stock (bonding vias, solder mask, etc). Corporate also has different demands and much bigger budgets for materials, dedicated wet/dry lab space, and tooling, than I do so the equation is pretty different.

@@treelineresearch3387 I see two versions of a product: Prototype and Production. Imho a prototype rarely needs soldermask, but it can also be applied using the resin printer - some experimentation may be needed, esp. if working with 01005's ;ø) Via's can be easily made with rivets, if a double sided board. 2+ layered isn't a DIY project usually, unless you want to do your own multi-layered 2-layer 0.8mm's + more experimentation, gluing, etc. Prototypes are excellent for concepts, or *very* small batch jobs. For everything else, yes - it does not make sense to make pcb's at home any more. Etchants, developer and soldermask can/could be obtained for relatively low amounts of money - and stores for a while. Also doing it at home could save on import charges and fees. Having the post office/courier (read: required) doing customs clearance often adds a substantial amount of money onto the price of the PCB's - depending on where you live.
@mdo1989 Рік тому
Was a nice video. Could you go a bit more into detail about the fabrication of the solder mask, or create a separate video about it? You apply the mask, cure it and then remove the cured mask from the pads? So if the machine is well calibrated, I would not remove any copper and would not have to create a mask for the solder mask and etch it but how do I calibrate the machine for such low tolerances as I modify the pcb when applying the solder mask. Not sure if my comment makes sense to you ...

hohohoho omg nice! Might be the best desktop machine besides AdditiveProductionMachines. Very impressive. So complete

Is this the easiest to use in term of home fabricated PCBs (other than using an etching solution approach)?

4000 is insane, considering the results...it is still wiser to continue using JLCPCB , i can wait

their PCB's are properly painted with multiple coats which is why bought ones look better than homemade ones, and using a special coat layer on top of that.
@treelineresearch3387 Рік тому
I want to say the vids I've seen of actual PCB fabs were using a film transfer process to apply photosensitive mask that then gets UV exposed and etched away chemically, so the consistency of the layer was controlled more by the film manufacturing than the application process. Not sure what that process actually entails as far as heat/pressure and if it's feasible to do at garage scale, or if the film is available in small quantities and is storable at room temperature (not sure if it's a precatalyzed material that only stays latent when refrigerated, like carbon/fiberglass prepreg). Spin coating might be a viable alternative for more consistent application of a liquid/gel though, and super easy to implement.

To prepare GRBL to GCODE PCBs I use Flatcam Beta 8.994, it is the absolute best software for that purposes and there are tons of videos on YT about how to use it. (it's a bit tricky to find the beta but not impossible)
@MrBaconinabun Рік тому
would love a shot of it, but far above my humble price point

Will the carvera cam software allow the double sided PCB?
@guillermoascolani2041 Рік тому
You should try FlatCAM to process the gerber files into GCODE. The program is a bit unstable, but it has a lot of tools that allow you to get your job properly done. I recommend watching a few tutorials first, because the program may not be that intuitive at first use.

I went to a vocational high school and took electronics. We learned how to make our own PCBs with those fun chemicals. Now, I remember my shop teacher talking to us about how hard it is to get the right chemicals for removing copper from a PCB and how easy it used to be. His exact words for the description of why we can't use better chemicals was: "You know what happened? 9/11 happened."
