I started with Surfcam then MasterCAM, done some TEBIS, Fusion 360, AutoCAD, Eagle, Solidworks, and probably some others. I've even used inkscape and GIMP to cleanup and convert images into models for measurements and reverse engineering.

I have never had the trouble I have with FreeCAD. Have seen others complain about it as well.

Metal printing and such would be in the context of building a CNC shop and him being proficient at modeling and such after playing with an FDM printer for a few years. We're talking a pro grade printer and sintering oven. If he has the interest, my son could handle printing and I would handle CNC. That's the dream. Requires tens of thousands of dollars. Baby steps first to see if he has the drive. Bambu is almost certainly not on the list unless I trip up on an incredible deal.

I guess my ultimate goal is that he learn to model and begin building proficiency with CAD to prepare him for CAM. I also want him to start getting a feel for CNC movement and thinking in Cartesian. I think the best way to get there is by getting him engaged in printing. I'm not sure if tinkering will help or hinder this process. I know it helped for me, but I'm not sure if it will for him. I think it might. Still pondering the appropriate level of tinkering, but am leaning towards Voron, not sure if that's my personal bias.

Yah, these days I refer to anyone under 30 as a kid. Especially in a manufacturing or trade context.

I check on FreeCAD every so often. The UI team should be forced to wear underwear made from pinecones until they fix that horror. Been doing CAD/CAM for more than two decades and FreeCAD is so unintuitive that it is unusable. Making a sketch or taking a measurement shouldn't require research. Recently tried it again and was unable to sketch angles for a brace I was making and needed dims on. Tried libreCAD (unfortunately 2d only) and was able to get my angles and lengths in 15min or so without any tutorials.

I hear and agree with what you're saying about open CAD software. However, I don't want my son trying to learn something that will just frustrate him. I wish OSS would catch up on CAD/CAM, I could ditch windows for good.

I watched the RepRap development back in the day, but eventually stopped following 3D printing closely. (Ended up with an Atlas Craftsman lathe with milling attachment that did all the home manufacturing I needed). Prussa and Voron are our top contenders for printers now. He's got a spreadsheet where he's comparing specs and I'm getting him to read the quick starts and manuals.

I'm going to dig into the Voron world and see if it's a reasonable project for me to support my son on. Not sure if it will be beyond his attention span. Otherwise it will be either a Prussa or maybe an Ender.

Dangerous to billions? I don't think one ocean empties into the other like pulling a plug in the bathtub.

Jebus. I still haven't figured out if .ml is government funded or true believers. Very strange to me.

Fucken hell, that's the correct fucking way to define a gap in armor. Bullshit. I really want to try a bunch of slurs out and see what sets it off.

FDM for now. Not planning on doing casting or proto mockups at this time.

Envelope is not a large concern, I assume it is similar to machining. You buy 1.5x the size you think you need and find out it should have been twice as big. The plan is to cut teeth on this printer before moving to something better/larger.

Mostly want to use the printer as a tool, not bothered if some tinkering is required. A Harbor Freight machine like a drill press or band saw is a 'kit'. Use it for a little bit, take it apart and fix the manufacturing shortcomings. I'm okay with a printer of similar build quality as long as the bones are good.

Voron sounds interesting, have seen the Enders as well, seem to be okay.

I get what you're expressing. I'm not going to try and force him to enjoy it if he hates it.

However, he's about to be as old as I was when I got my first job. Some personal discipline is necessary. The family business is going to be machining and at minimum, he will push buttons and load parts at some point.

He spends several hours a day playing Storm works and has been teaching himself the Lua scripting that is in it. He has expressed interest in civil engineering, architect, and all sorts of mechanical things. He's nuts about cars, tractors, trucks.

We're kind of reaching the point where the rubber meets the road. I have provided Arduinos, discrete component kits, knives for whittling, his own rolling tool chest, pirate server, rpi, FFA involvement, python, and so on. There has been some engagement, but, not the deep engagement he shows with gamified machines.

I need him spending less time gaming, even if it is an engineering based game, and more time building some practical skills. He's at the age to begin transitioning to an adult. He'll be driving soon. It is time to be a little firmer about learning real world mechanical skills. It's my duty.

He's been very excited about the printers at school and the seat of Fusion. I'm hoping this will spark the fire.

Given his interests, it's critical he actually learn how to model instead of playing with the limited implementation in something like stormworks. (He frequently shows me machinery he's built in game and we discuss them.)

He did built a kit picnic table this year, where he had to chop saw the 2x4s and screw it together. I've about got RTFM hammered into him.

I'm also pushing him to research his interests instead of just watching YouTube videos. He doesn't have to be a machinist or even mechanical, even though his interests are there. However, he must begin learning how to work and teach himself.

I was sitting around stoned out of my gourd with a coworker (pizza delivery). We were listening to music with the stereo way up and he played this album. He was watching me when it started, kept a straight face through it, died laughing when it got to rabbits wearing glasses. Damn, that's a good memory.

I like this idea. We're raising chickens and probably rabbits this spring. If you're going to eat meat, you should face the reality of the life you are consuming.

Yah, that's been standard lie #752 for a long time. Anybody that's worked with immigrants knows the vast majority are just people getting by and trying to build a better life.

Thank you.

This is gnarly and chilling:

Today I'm also signing an executive order to instruct the Departments of Defense and Homeland Security to begin preparing the 30,000 person migrant facility at Guantanamo Bay," Trump said at the White House.

Edit: anybody know if he actually signed the order?

Welp, that's less than optimal. Not purpose built but also out of sight and mind.

Do you have a source for Gitmo being used for deportees? Again, serious question.

Are they building them already? If so, do you have a reliable source? Serious question.

Huh. So how would you describe yourself politically? Are there governments you approve of?

Your removed post at the same level in this chain. You called the guy you were slapfighting with a nazi and there was a Hitler comparison as well.

I can't tell if you actually believe that, are just trolling, or are muddying the waters to control the narrative.

Yeah. Perfume and smoke does it for me as well. Sweet liquor on the breath. Smells like trouble.
