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
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.
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.
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.
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.
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
