Dude, you rock. And the LR3 rocks!
Anyone know if this is going to be a problem? I guess I will just use a file if needed. Maybe when I cut the other one I’ll add the dogbones
It doesn’t add the dogbones because, when using trochoidal, the milling width is bigger than the dogbones. You can’t push a 4.5mm (because 50% oscillation) tool in a 3mm opening. If you made them bigger, it can cut them but wouldn’t look that great.
This. But I believe you can go in and manually add them. And it will make them large enough for it to do with trochoidal. You can also back off on the trochoidal width a little to make them not not so large. I try to always stay at 25% minimum. I run 50% any time I can though
Are the braces not chamfered enough to not need the dogbones?
I think the notches are to fit snugly around the braces, as the snug fit potentially enhances the rigidity of the gantry against racking etc. You could manually file the rounded corners to be sharp. But that’s a lot of work. I think the best approach is what @Jonathjon suggested. Manually add the dog bones in ESTLcam, but also:
FWIW, my model has 0.5mm clearance for the braces, (if you change the 17mm width parameter to the correct 18, lol.) which I believe Ryan’s also has. I did not overcut my corners and it wasn’t a problem. I was prepared to file sharp corners into the piece if needed. I believe that there is also a bit of clearance in the brace piece itself over the nominal width of the openjng as well.
With a 1/8" mill, the tolerance should be OK. With aluminium, you might need to file the corner, but I bet not much.
Sweet, will let everyone know. I used Jamie’s Vector76 Strut Generator.
Almost done printing all the parts. I think the hardest is the tool mounts in PETG but I got it working. It’s hard to get PETG to stick good when you have finer details.
I worry about my tool slipping up. My Makita used to do that in my LR3 and I would just have to tighten it more. PETG it is more slick, the tool might move around more.
I used an ASA tool mount on my LR3 and never once had any issues with it slipping. Not sure if that is an option for you or not.
I do actually have some ASA. Since my PETG is almost printed out, I’ll give it a shot and see if I have problems. Then we know if we should change our guidance
The dust skirt is way too loose on the shoe. I can’t imagine this is going to stay on once it has TPU bristles.
Thoughts?
It’s a really loose fit for me as well, but it has never fallen off during a program.
What nozzle size, wall count and infill did you use?
Loose fit came up during the beta, and was noticed when the more recent compact shoe/skirt was made. Ryan then edited for more positive connection. There’s been a few versions…
0.6mm nozzle, 3 walls, 30% infill, 0.3mm layer height.
I think it should be tighter.
Edit - mine is PETG which is a slippery filament. That probably doesn’t help.
This is going to be chewed up faster than Doug’s remix, but I will try it
I contemplated adding a small magnet. I like magnets.
I was going to say magnets too. This is a remix someone is likely to do.
I’m not going to even think about it yet because I am still building the full size final LR4 and I don’t have the new dust shoe printed for either the small test LR4 or the new full size final.
