@ Dan SupraGuy) — I appreciate your staying in the battle.
LOL @the last statement in your reply.
I will have my final list redacted soon and place the order.
Your reply will save me a lot of time, and between your info and the Teaching Tech, I will be able to get the nominal visualization I seek.
…your reply has put a great dent in that direction already.
Your list is the jumping board.
Thank you so much!
I know this is yet another long post, please bear with me… I promise, this is the last one. I have added a 2nd section below(clearly ‘demarked’) …brings up issues about the main ingredient behind all 3D modeling/CNCing.
I understand that if you are not a programmer some of what is discussed at the OpenSCAD link I provided, may hit you like a foreign language, but do not sweat it, whatever you gain from it is worth the visit. The multiple replies at that link do culminate to a layman’s understanding and it ends.
A lot of reading… so if you are not so inclined, don’t waste your time, as it is necessary to read it all to extrapolate the layman’s understanding.
your “…it depends…”
- I am fully aware of that, but the short list you provided answers my suggestion, nicely circumventing the ‘…it depends…’.
I am a calculated(ing?) person, obviously. While I vacillated between replies, I leaned back towards a 3D printer solution. But before redirecting myself I browsed back my list of reasons-I-opted-for-one-thing-or-the-other. …I quickly saw that I must remain on the CNC approach. …if anything for one main reason…
…when I make parts I often have to do retakes and readjust, as in, drilling anew, carve, reduce, etc… and that requires, knives, chisels, drill, routers, sander, … and plastics are just not my preferred choice to carve, sand into. Wood is my medium of choice as of now.
Surely, once a design is debugged, this is moot… but the majority of my time is on the R&D side, not the production(which for me is practically non-existent since most if not all I do is 1-off).
Thus I have to have CNC power no matter what… and I want to also satisfy the other reasons I have previously brought up.
As for the tubing, I have to find a local source… 20ft length is way past the less than 8ft shipping restrictions and I can’t see that it would not be made untrue by the handling.
Firmware and capabilities:
I want to have the power to load the firmware electronically rather than deal with a million SD cards or memSticks, if it can be avoided… and also hopefully have a way to control via computer and CELL…(I may be dreamin’!)
So, I have to look into the Raspberry PI add-on and what that entails.
I know from Teaching Tech the Raspberry is compatible with the SKR boards.
The TFT looks good… I am generally not fond of tiny screens except as back up or when it makes sense, like the simple operation of the equipment… and big screen interfaces when pounding on parameters and saving presets and repeat jobs.
I want to have all of these items in hand when I build/test/start using the equipment… Several SD cards if needed, mem sticks, and what ever else comes in the game.
SECTION 2 : the CAD/CAM/CAE, … requirement.
[ Solidworks, Aspire, Vectric, OpenSCAD, Sketchup, freeCAD, … engineers packages, all covered below.]
…and I am still trying to find the magic so-called free CAD/CAM software.
freeCAD is theee ONLY standalone one I found to be free. ALL the other so-called free ones are either trials or too cumbersome and weak to deal with or CRIMINAL THIEVERY CLOUD VERSIONS.
There are a few that are standalone and can be purchased outright rather than forever yearly fees… but, that is another ton of time to waste to find out they suck. (Aspire, Vectric, …)
[ After one has customized it as needed ], the best I have found is Sketchup. It is no longer free but is the most affordable at roughly $50.00 a month.
NOTHING out there beats its ergonomics, its speed and actual intuitive user interface(GUI). I still have the 2016 free standalone version, and it may actually be at a good enough level to have the needed functionality.
All I may need is a converter/translator for the output file.
OpenSCAD is one that is openSource and free and can do it all, the only issue is that it is nearly entirely strictly programming based …and that is about as slow an approach as can be, until one has created a great amount of presets that can be copy/pasted… a weak GUI, hardly anything visual on the building side, only on the preview side AND WEEEEAK/klunky!
(small taste: OpenSCAD Tutorial/Chapter 1 - Wikibooks, open books for an open world
…and it uses a proprietary language. see this discussion:
(OpenSCAD - OpenSCAD language - replace it with Python3
…the OpenSCAD existing interface uses such klunky sequences, that-alone makes it trash to me… until they eventually develop the Sketchup-like GUI or allow full customization of keystrokes, offering the best of both worlds… then it will be a(thee) tremendous free tool.
I would have to write code to translate all the individual commands and scenarios into a visual point-and-click interface… Wo! see you in a quarter century!
Sketchup already does that and is updated constantly… no-way to compete, unless I join the team at Trimble.(not gonna happen… too old)
…again, Sketchup has nailed all of that so completely, nothing can touch it. It’s at the top of the heap forever. Even the more advanced packages like Solidworks will have to eventually line up or die like dead tongues… notice, I am not mentioning any and myriad of the really advanced systems that engineers and designers use… the list is massive.
Note: many will say Sketchup is not accurate and all sorts of non-sense to bash it… they just have not figured it out yet.
They are just running their silly ignorant tongues.
Once one grabs the understanding Sketchup embodies, one can design precise complex ‘multiblock’(infinite) creations in one evening, the first evening if having watched the proper tutorials. …and don’t go swallowing the lie that Sketchup is not parametric. The new versions ARE… plugins now, and I am sure eventually intrinsic.
Watch this video, though architectural, a great example of the speed and power of Sketchup. …much harder stuff than simple mechanical parts.
I had a great need to go lie down, but happened to watch the first few minutes of it, and never peeled my eyes off-the-screen until the entire hour and 30 minutes went by… my eyes stinging and crying in pain.

freeCAD which looked promising at first is still a horrendous piece of mediocre garbage. The time one wastes on that stagnating completely non intuitive tool and utterly crappy work flow, is just silly, not recoverable!
The voluntary developers of freeCAD are the likes of the mediocre middle school level pupils I had to suffer, hindering the class to a crawl.
- free is good, but not if it robs you of your time. It’s a trap!
…sad, isn’t it!? since it is the ONLY truly free standalone visual/GUI package at this time.
I just realized that you may have stated you use freeCAD… LOL!
Thank you for all your help,
…on the rebound.
