I can post that as an svg if it helps…
It is PLA because I think I finally have PLA figured out on the v4 at least at low speed. i’d really like to triple the speed, but that gets complicated.

I think I’m good now. Most of it I can figure out just because I know how Ryan models things lol. But having something to look at that he double checked is always good!
PLA was the easiest to print on my V4. And I’ve gotten the speed well past what I can cool lol. Nothing has changed except it hasn’t been used in a month and now my first layers are all screwed up. Just got back home and about to try and get it better. They aren’t far off but anything is too much for ASA lol
Those look AWESOME!! I’m very curious to how they stand up against aluminum or printed parts. Hopefully they work well for you!!
Yeah, these are looking great. What’s your laser cutter setup, seems like you’re happy with it for polycarbonate instead of using CNC?
So i was reading a klipper post about the manta board and voltages… the skr pro 1.2 states it can take 12-24V. The heated bed I have is 24V. Would it run on 19.5V? Would the power supply be stressed or would it just take forever to heat? I’m lazily asking because I dont’ feel like sorting through google if someone already knows (@MakerJim?)
It is an 60W CO2. We don’t cut polycarbonate with it, only acrylic and only because I had a scrap piece the right size. I think I feel about cutting aluminum kind of like @DougJoseph has mentioned about his voron build: nervous; for good cause.

What are the specs of your heated bed? In particular, what is the resistance and rated power of the bed?
A 150W laptop power supply may be iffy.
Bed info states: 24V 220W (ender replacement)
So probably not a good idea to use a 150W laptop power supply brick?
EDIT: 19.5V on a 220W bed, it will need ~11.5 amps and the 150 only rates at 7.5, so it will get too hot. at 24V supply could put out that much power at just over 9 amps.
Correct. That power supply won’t work for that heated bed.

I am going to be cutting my Aluminum parts when I get back from school end of next week/first of week after. Going to do my best to document everything and post plenty of pics/videos to try and help everyone feel a little more comfortable to give it a shot.

Whoa!!! Did not take you long!!
I have to wonder if that acrylic would have been stronger without all the cutouts though. On netsal it is still rigid. Hope it all works!
They should hold up well. The sandwich is basically making a composite.

“Ron” is on hold currently waiting on parts:
- bolts (I just picked up a box of 10-24 bolts for the sandwich composite parts)
- x and y linear rails
- belts
- extruder / hot end
- extrusion (short by a couple sticks)
I’m rethinking the “budget” aspect of this. If it is worth investing the time, it is worth doing right, not just twice, so parts will be acquired as the side gig provides means to get them.

After having redone my V4 2-3 times it can go either way. I learned a ton and changed things I wouldn’t have changed before the first build. But then again this isn’t your first build so that might not matter here. I do hope that I can put this one together and use it without having to redo a bunch so I get exactly where you are coming from. And I think this design is proving worth a nice build.

While figuring out what to do for parts thinking maybe the v4 needs to become a v5 and I build a smaller v4 with leftovers since I have them…

I went back and forth on keeping the v4 or dismantling it and building a V5. Ultimately decided to keep the V4 as it is and just build another from scratch. Every time I look at the V4 and know what all it took for me to get it working like it is. How many mistakes I made that I had to go back and learn and fix on it. It’s become pretty sentimental to me lol. And now that it’s all dialed in good I just can’t bring my self to take it down lol. I’ll retire one of my other machines before I do that lol

ok, so you do understand why I’m pausing on the v4. sweat equity.

Absolutely
Yeah, based on video clip durations…
- Spent ~40hrs building on camera, and many hours designing/assembling off camera.
- Looks like ~30% of that time was marked as fluffs up, fails and troubleshooting problems (e.g. dead CANBus board, and general CANBus setup)
- ~14hrs was experimenting and making non standard features.
- Only ~11hrs was spent assembling and wiring up the Core V4 design.
Future build should be way faster with knowledge gained from V4.
So, am more likely to eventually build a V5 than tear down my V4 desk ornament/lamp that happens to print.
Not sure when though, especially if LowRider 4 is available to build soon?
