How are you making out with this collet rack? I don't want to sound fearful, but years ago I converted my milling machine to CNC with Mach3 and purchased a license for CAM BAM. The issue was the amount of leaning and then forgetting of how to use the program to draw the part that I wanted to make. Every time I wanted to draw something I spent hours on You Tube going through video's to relearn how to use the drawing part of the program. It is to me, so difficult that I revert to traditional methods of machining parts.
That project is still a priority. But it's taking a backseat to other aspects of my life. Doctor, dentist, wife, grandkids, neighbours, we are also planning a few days of vacation. It's also not a project I am married to. It's just a, stepping stone - see further below.
For right now, I am learning how to sllice an existing design as per
@Arbutus instructions, but it's never as easy as it sounds. I've had to review the Bambu briefing, but it's just not landing in my head in a way that I'm confident in. So I'm starting to think about doing it in cad instead. A flat block with a pattern of holes in it should not be hard to do. Heck, I might even use Alibre instead of Fusion just to try it out. That said, if I do switch to CAD for this project, I'll set the project aside in favour of something else that fits my progression plan better - see plan below.
I might also try printing something I've already done in CAD (lathe stop, DRO brackets, etc).
Your concerns about learning and relearning are partly why I don't ever want CNC. The other reasons being that I love turning handles, I love the feel of the cutter working in my hands, making the machine happy, and I very seldom make multiples.
Even if I'm only in the planning stage of a project and I haven't done anything yet, my mind easily embraces the anticipation of manually machining, and it abhors the idea of punching numbers into a keypad. So ya, no CNC for me. Not now, not ever.
Looking at your project, purchase a solid block of plastic and machine it the way you want it currently in my mind makes more sense. I can see it in my mind and the steps to make it happen which currently I cannot see nor understand in 3D printing. Help!
Just go to the dollar store and buy some 3/8 thick cutting boards.
Before I got the 3D printer, I had always planned to do just as you guys suggest. Buy some decking boards and just drill holes in it at the required spacing. You guys are both right. It's an Easy Peasy job on the mill or even a drill press.
But that misses the point. For me, the collet tray is a stepping stone, not a destination. It's all the other more complex things I'd like to make when my skills have improved.
My simple plan was, and still is:
1. Simple library part - Benchy
2. Complex downloaded part - that turned out to be a spool tray just cuz I needed them anyway.
3. Complex modified part - collet tray.
4. Simple CAD part I designed - TBD
5. Complex CAD part I designed - TBD
Not to disillusion you, but the CAD issue is real for me too. As real as your concern is and very similar too. Like you, I have not been able to find a way to "stick with it" enough to become comfortable with CAD. As fast as I learn things, I lose them in the fog of my mind. It's just easier for me and the things that I do to grab pencil and paper, sketch something, calculate a few numbers, grab some stock, and head for a machine. As weird as it sounds, I am actually hoping that 3D printing will eventually become my reason to get more familiar with CAD and hopefully retain more too. Sort of a chicken and egg thing.
I am also a bit scared and also relieved by what I'm all finding in terms of ready to go projects on line. There are so many people out there posting models that are ready to download and print that you can find almost anything you want. Who needs CAD? But that "no cad guy" has to be happy with what is already there. That prolly isn't me. In fact, the collet tray is already proving that I'm not that guy. Nothing out there is exactly what I want.
Bottom line - so far so good. I'm happy with my slow progress. It isn't a race. I'm thinking I'll either postpone the current collet tray in favour of an easier one, or set the whole idea of a collet tray of any kind aside for now and do something else that rings the same bell.
For right this moment, I'm still learning how to split an existing design. My instincts say it's easy, but the details of how it's done are alluding me. The light bulb might come on today. Stay tuned.
