Status on Lowrider 4

I cant count the amount of times I have held on to something for 10 years, and when I FINALLY throw it away, within 2 weeks I or a good friend will need that exact thing I threw away.

This exactly. Please explain that to my wife, who thinks I’m crazy for holding onto stuff “just because I may need it in the future”.

Hmmm, on second thought, she may have a point…

Most of the time I forget I even had “it” :rofl:

Dont listen to that voice. Last year i threw out some stuff i been hoarding for 20 years and needed it two days later.

No requirement that you self-incriminate here…

I made the comment once that I wanted to keep something from the trash heap. Why? I said it had “intrinsic value.” It could be used for something else and I could see value and potential in it. Now that term is used to ridicule me, but I feel a kinship with you because it sounds like you understand.

Now that you are here, he can count on you to find it :wink:

She finds most of it for me. I am WAY too ADHD. I leave stuff around all the time. If its a recently lost then I can usually retrace steps, but if its been since “last time home” or beyond good luck LOL

Yes, I’m usually tasked with finding things. I try my best to clean up as we go but it’s not always an easy task. My ADHD kicks in and …squirrel…

Ryan,

Would PLA-CF be a better option for strength and durability… Or just go with straight PLA?

I was ready to go ASA-CF… But with so many saying just use PLA, I’m rethinking…

Thanks…

Use PLA, PLA-CF (if you trust the brand CF can be nasty), PET-GF or CF, or PC-CF or GF.

Rigidity is by far the largest factor.

All of this will be in the instructions very soon. Let’s hold off on specific questions for a bit please.

Crud - I was out milling some Star Wars Coasters (well, ruining some material and learning anyway) and I’m pretty sure the core is cracked near one of the top bearings. Grumble.

Even if LR4 is released my fastest “return to function” is to print a new LR3 core. Uggh. Decisions, decisions. I keep tightening the bearings and it snugs it up for a bit, but I had to adjust it twice today. There’s a little layer separation near the upper left bearing. I’m guessing now that it’s more than cosmetic.

I may try PET for heat tolerance.

Print a new LR3 core in PET-CF/GF and get a feel for printing it. Then while you are still using the now back working LR3 you can print the parts for the LR4 :partying_face:

Yeah - I think that’s my plan. I haven’t printed with it before, so I ordered a kg and will mess with it. I’ll report back. Found some reasonable stuff from Polymaker.

Huh. That must be new. I don’t remember seeing it from them last time I looked

Honest question here, why PET-CF/GF and not PLA-CF? I’m new to these filaments and looking to get my feet wet, but PLA-CF seems like a better starting point, at least for me. Would love to hear more perspectives and what others have had success with.

In addition to being way cheaper, seems like the PLA-CF would be less finicky to print (drying seems easier/less necessary) and comparing stiffness the PET-CF does seem a bit stiffer, but not sure how significant that is considering both are already significantly better than standard PLA.

Another question to tack on here - anyone with experience can remark on the dimensional accuracy of printed parts in these “advanced” filaments? Wondering how best to take shrinkage into account, if at all.

PLA has been the historical spec for the printed parts. Especially if this is your first print for a V1 machine.

Ryan has always let people know that PLA is supported, and that the other filaments aren’t necessary.

So, my suspicion is 2 fold. I live in Arizona, and my garage is hot for long periods. I was also plowing through some panels for a modular cabinet I was building. So I’m guessing the heat and the stress through the summer months led to some weakening (on one of the large bolts that hold a bearing, so already a stress riser.)

My current core is PETG-CF. I like it, but it’s still not as rigid as PLA. I think it was fine overall, but I noticed that the nut traps didn’t work well (I ended up gluing them.) This is also my second core, I was working on the machine and caught my pantleg on it and sent the LR3 to the concrete floor. I replaced several parts after the incident. (Still frustrated with myself, dumb mistake.)

Anyway - I never had trouble printing the core with it. I did try PA6-GF on a lark, but my old printer isn’t really up to it. I have a new printer, so I’m curious about that as well.

My advice is to print in PLA unless you’re trying to solve a specific problem.

Out of respect for Ryan I will hold off on giving my answers to your questions. Just be a little patient and they will all be answered very soon :partying_face:

That’s something my students could have said if they didn’t have a clue… :joy:
