For folks looking to buy parts… Just noticed https://biqu.equipment have an Easter sale with prices that seem a bit better than the Sale they seemingly have for the few regular days we have between seasonal/festive related sales.
Anyone able to share BOM they have that covers parts beyond Specialty parts available at V1E Shop? Starting to cobble something together, using info from various topics, and VORON Design - Sourcing Guide even. Figured I should check with you guys first, before going to far, guessing several folks here have gone through this process already and have comprehensive lists, or spreadsheets even?
I have bought several items from AliExpress related to my hope for building a couple of these repeat V4 printers. These purchases have included bed heaters, solid-state relays to switch on the mains-powered bed heaters, and flex steel magnetic print beds as a package set that comes with the magnetic sheet. I’m trying to think if there’s anything else I’ve gotten from them. I am on the road right now, so I can’t provide you specific links at this time.
I have bought a couple of namebrand Meanwell power supplies. One of them was bought through marketplace, I think Walmart marketplace actually, but it was actually being shipped and sold from a company that carries Meanwell. The second one I bought straight from the same company but from their own website I think.
When I was building my Lowrider V3 plasma rig, I could not find the 24 V power supply that I had purchased for it (not name brand), so I wound up using one of the Meanwell power supplies that was intended for a repeat v4 printer. So if I want the two printers to match, I will need to swap in the power supply that was originally intended for the plasma rig. It is a thicker, fatter power supply than the Meanwell. Space is less of a concern inside that repurposed desktop PC tower, so that bigger power supply would fit better in there anyhow.
A lot depends on what you end up doing I know i severally under estimated the amount of screws a tnuts for my build. But honestly once Ryan says he is happy with the Panels I believe i will be switching to those. These printed corner brackets look great but there is just too much flex in it for me to be happy with it.
Yeah, am seeing ~115 bolts needed just for attaching the Front/Side/Bottom/Back panels, guessing M5x8 button head, assuming 1/8" thick acrylic panels? That’s before adding any corner/right-angle brackets.
Some years back I bought a lifetime supply of M5 screws in various lengths. I mean a lot of screws. So I will probably use M5. I suppose I could save on how many of the nuts I would need if I were to drill into the aluminum extrusion, and then tap the holes. But I will probably buy a big supply of the nuts just to save myself some work, and preserve the ability to adjust as needed.
- Linear rails all use M3x8 - (x+100+(2 * (y+ 50) + 3 * (z + 50)) / 25 - Excel… =(A1+100+2*(B1+50)+3*(C1+50))/25 - e.g. 62 for 200mm^3 - One stepper mount marked with an “8”
4
M2.5x12
2 x 2 Endstops
???
M3x10mm
~113
M3 or M5 Button head by 8+ mm
- 4 x 25 Side/Back/Bottom Panels - 13 Front lower Panel - (M5’s will have less wiggle room) - 8mm for 1/8" panels, 10mm for 5.5mm+ (e.g. 1/4") - Measure/check length needed for panel thickness
Go to your local welding shop and buy a drop. I was able to get a 2 x 4 piece of 1/4" for $100 and milled my support and plate out of that. and have enough left to do another one if (who am i kidding…when) i build another one
Curious if there’s a voltage recommendation for power supply (for SKR1.2 or similar)? Guessing 24v but want to confirm.
Assumed everyone’s using 24V power supplies. But then I saw a Repeat with LRS-350-12.
Then I saw v3 docs specialty-parts has links for Power Supply, the filastruder link goes to 24V and the amzn link goes to a page with 12V (but other voltages/ampages can be selected too).
Curious what material people are using for the triangle’sh Bed Support Plate.
1/4" painted MDF or Plywood? Using Alu seems overkill for something that doesn’t support anything in the middle, seems to be solid mainly to help retain bed heat? Also for 300 x 300mm Usable, would need Bed Support Plate larger than 12"x12", so larger $$ Alu stock would be needed.
I made mine from Aluminum because I didn’t know any better. I think 1/4" plywood or MDF would have been fine. But it does look cool knowing I cut it out on the LR3 lol
