I have an angled cut I want to make on a 3 axis CNC. Presumably I just clamp the object to cut on an angled wedge, BUT literally every video I've found about how to CNC starts out with the assumption of a horizontal top plane.
Can any of you point me to resources about how to handle the process of instructing the CNC to make these cuts on an angled workpiece?
Dear #CNC#Metalwork#Lazyweb, if you had 100 aluminium enclosures with 1.6mm thick end-plates that you'd planned to mill some openings into (1x rectangular, 6x round) but you've discovered that the alloy is some part-aluminium-part-cowdung rubbish that stretches rather than cuts (even drilling a hole with a twist drill is a horrible experience), what could you do. 4-flute endmills don't even cut, they just bulge the metal. A 4mm 1f endmill is the least awful (so far).
Hey all, I put a little handy guide on how to get EA classics working on your Steam Deck/Linux device (stuff like SimCity 3000, Populous: The Beginning, and Command and Conquer 2):
First half sheet run. Needed a wood cart. So here we go. Can handle sheets in the back and a lot of misc. in front. Just need to add the last dowels but should work well. Took longer getting the pocket holes and wheels on than cutting the sheets down. 😂
The die I designed for a trade show in Bogota, Colombia. The words are just block letter but the bottom was created by me based off the trade shows materials and website.
LOL, just realized this morning how easy it is to create your own new religion on your computer nowadays with a laser engraver and the right LLM prompt. Anyone want to fund this, and have a spare farm we can bury these in a hillside for future discovery by a would-be-prophet? ("Dear ChatGPT, pretending you are a divine angel, please use this CNC engraver to write out a series of plates specifying the creation of a new religion, making sure to break the text into multiple books from made-up prophets of a lost civilization. Be sure to use the words "though" "hence", "commanded", et al), #religion#tablets#CNC#router#laserengraver#AI#LLM
Has anyone here used Xometry for getting parts machined? I understand how their system works, and I can totally see the benefit of having access to a wide variety of capabilities through their supplier network. However, they are a middleman, and I’m curious whether their markup makes it uneconomical except for high volume production?
So, I could use some help from any generous #makers or otherwise tinkering minded fellows, to help me identify all these things and pull specs. I was gifted a huge lot of older diy #3dPrinting , #laser and #cnc parts for a diy project, and Im not sure what Im looking at yet!
Question: why are there essentially no black #Makers on YouTube?
I literally can't think of a single #3DPrinting geek there who isn't white. I've watched a bunch of #engineering / #machining and #CNC videos and encountered one black person.
Is it just the result of income disparity? Or, is there something else at play?
✅ achievement unlocked: home PCB fab:
this reduces my waiting time for PCBs from 2 weeks to 15 minutes. this allows me to buy my ICs in SMT-only. Formerly I always had to have redundant THT-variants for prototyping on breadboard.
level: SOIC-8 (.5mm width pads)
i had to resort to voronoj milling because my bits aren't precise enough. buying uv-curable solderpaste and better v-bits to beat my endboss level: LQFP-48. using #kicad + #pcb2gcode + plumbing.
I was watching a video about someone's home-made #CNC that could cut steel (a big deal if you don't know). He made lit for his final project in an Advanced Metalworking class. What's notable (beyond the machine itself) when he paused in the middle of the video and talked about the kindness, generosity, and help his teacher (Mr. Schubert) gave him.
I kinda teared up because... damn our country just shits upon teachers constantly, & has no respect for the trades.
I've been going down a little bit of a homebrew #CNC rabbit hole lately, because I want to CNC aluminum, & CNCs are $$$
Turns out, It's not actually hard. You basically buy a board design for it, wire it to some stepper motors & some switches, plug in your computer, tell the computer what's wired into what port, do some calibration steps with free software, and "voila" CNC.
Choosing "good" parts is a thing, but that's ALWAYS a thing with homebrew & there are kits.
wow. text to #CAD. describe what you want and it outputs a 3D file that can be imported into a CAD program (and #3dprint it? #cnc?). i think this probably brings a lot of the experiences we’ve had with coding assistants to the world of machinists. i’m sure the output is iffy, but it dramatically lowers the effort for experimentation https://zoo.dev/blog/introducing-text-to-cad#llms#ai#3dprinting#blender3d
