The muffs were to drown out the sounds of Ben shagging your mom.

I will make a video on it soon

@@АлександрЕфименко-щ9р correct. It only goes about half this fast for quality prints.

@@HonestBrothers безусловно этот принтер заслуживает уважения но зачастую такая скорость при изготовлении качественных детали особенно с поддержкой не нужен. Но он мне определённо нравится 😀

@@HonestBrothers возможно я бы такой купил но в России такие не продаются (

@@HonestBrothers Я желаю вам не останавливаться на достигнутом а делать больше лучше и хороших вам успехов.

There will be quality improvements I make that can be used at all speeds

@@wykonczeni has anyone really tested this? Seems to be a common trope amongst the 3d printing community, that doesn't have solid test data to back it up. The printer is down for a minute while I get my new hot end in the mail, but I'll do some big prints when it gets back up

A few more mods and I might make a run at that Benchy record.

Might be possessed.

@@redrider5441 should I make it go faster?

I can think of the perfect attachment! ua-cam.com/users/shortsGS2gy4KUiD4?feature=share

@@김상호-w9b 7 right now. I might add more!

​@@HonestBrothers Is that with the 4 motors you mentioned in another video, on y-axis? I can't quite see; what is the ratio of motors to belts to shafts? Do you have a few motors driving a shaft that all the belts are on, or decoupled motors driving their own belts? Related, are you running parallel wiring to the motors or separate drivers? If 2804s and TMC5160T Plus with the 10.6A current limit one could run 5 2804s at 70% their rated current (1.96) in parallel. I'm curious if that's what you're doing. Also curious what pulleys you're using. Seems with all that power you can use a larger pulley to get more teeth on the belt engaged, like 30t. I had dual y-axis setup with steppers in parallel and I was running into something above 800mm/s that caused stall whereas single motor could get to ~880mm/s. Maybe something minor with the pulleys at that speed is magnified. I did the pulley sync with energizing and disabling to get them close to synced. Was getting much more resonance before that and topping out at ~300mm/s before it was bad enough. Thinking of just focusing on single 60v 2804 for now.

@@funkdizzle3000 Y axis is 5 belts, two Nema 23's right now. I am going to switch them out for four 2804s. They are on a drive rod. The Y motors right now are on a 0.333 drive ratio to pick up speed. 60t on the motor, 20t on the drive rod. The 2804s will just go faster, so I might be able to get away with just using the 20T pulleys.

@@funkdizzle3000 motors are all in parallel when they can be. Makes tuning them a little challenging, but they are on 5160T Plus drivers. I rewrote part of the driver code so I can change the CS value on them. It helps quite a bit. Check out MattThePrintingNerd's new video, he's running the same mod. He got the 2804s up to 4000mm/s @ 280k accel.

The single layer VE was 800mm/s at 70k mm/s2. I bumped it to 2400mm/s shortly after, but I didn't think I was hitting that because the moves were too short

@@HonestBrothers damn, I thought 500 was fast on my p1s 😭

I'm going to print a bunch of pieces for a T-Rex skull soon with some Overture Turbo PLA that should take up most of the bed. So far I haven't had any issues with big parts, but I haven't gone full bed size yet.

@@mersiyecelik7564 I will get one going soon!

I'll see if I can put one together

@@pepe-stole-my-heart yes! I added the others quickly

@@pepe-stole-my-heart 800mm/s at 70k accel, I think

@@हधसदहदहदवदह two Nema23's right now. Changing to four 2804s soon

@@daliasprints9798 you on 5160?

@@HonestBrothers Yes, 2804 on 5160, 48V

@@daliasprints9798 github.com/HonestBrothers/klipper/blob/master/klippy/extras/tmc5160.py Implement that and retune your driver with the correct CS setting output by dump_tmc per the tuning spreadsheet. I'm trying to convince Dmitry and Kevin in a PR that I've fixed a problem they're not convinced we have. Let me know how it goes, I don't know if anyone has actually tested the code aside from me.

@@daliasprints9798 I can make a video on this in a few days.

@@daliasprints9798 I have updated the code, I was using the wrong spreadsheet. If you'd like to follow along and report feedback, please do so. klipper.discourse.group/t/tmc5160-py-hard-sets-cs-to-31-causing-chopper-hysteresis-issues/17655/2

@@arcusmeuscatt yes, theoretical top speed on the diagonal is 5000mm/s

I’ve never tried those. This plywood is super thin, so it didn’t really pose a problem with the blade I was using. I will definitely check the round ones out. Thanks!!

@@HonestBrothers My mother and father did scrollsaw wood projects for years. Everything from Christmas ornaments to hidden drawer shelves with nature and animal scenes. The round blades were a game changer.

@@tylerjones1645Thanks for the tip!

Agreed. Trying to get max flow out of it, and don't have a good solution for this yet

@@HonestBrothersgo horizontal, dual filament in combine the streams. I’ve gotten a prototype working but haven’t attached it to a machine yet

@@Volt64bolt I ordered a 3 in 1 from Geetech that they use on the A10T. Probably still need to make the heater longer somehow.

@@HonestBrothers oh wow that is certainly interesting, and here I am trying to machine my own from a block of brass

@@Volt64bolt not sure how well it'll work, but interested to find out! I'll probably have to get a heater machined, but hopefully I can just reuse most of the parts. I need to find a machine shop nearby or find a place I can machine it myself. Have you don't any flow testing? Does it flow more?

@@gqmeboi_2135 it's only like half the size of a V0 bed

@@HonestBrothers still small and I’m curious to see

@@gqmeboi_2135 definitely impractical

With the new motors I should top out around 5000 on the diagonal

I should! I've made some modifications since I last tuned it

What's the model of machine? I'm jealous you get to play with lasers

Yeah, it's real time.

I thought we were supposed to be getting a bunch this year?!

Two 4A Nema23s

What exactly are you printing with?

@@thomasdwyer5609 pla+

0.4 nozzle, 0.16 height, 0.4 width

@@HonestBrothers Wow, that's like 150 mm³/s peak (but much lower average). What speed racetrack can it do?

@@daliasprints9798 haven't tested it yet. I might make a video over the hot end idea and see how much of a difference the lengths help

Peak maybe 150mm3/s

Very long melt zone for the hot end. 70mm
