Ender 3 Biqu H2 Klipper Test. 150mms 200% calibration cube. Pressure advance tuned no input shaper.

[@ResistCircuitResist]

Id try input shaping just for kicks, might get even better corners at higher speeds with less ringing.

[@motelgrim]

I've been using the H2 on an Ender for over a year, I guess and it's capable of amazing prints. It uses a Dragon heatblock and mine is the bimetal heatbreak V2, so no gear issues. I've designed over a dozen ducts for it, just trying different arrangements but I think the fan on the right (like yours) makes the most sense. BTW, you want to put a bowden fitting in the top of it with a very short piece of PTFE poking out to facilitate loading filament and so the filament isn't swinging left and right during fast moves.

Try the input shaper

[@ITZNICKYYYY]

Try upgrading the bed and gantry steppers to bigger ones with more torque to eliminate skipping. That’s what I’m going to do with my ender 3 to achieve 175mms

Hello, could you share the printer cfg and maker firm please?

[@Cle_M3]

Stock it runs fine at 100mm/s or Atleast mine does, still have to install Klipper. Too lazy

[@jasonharris2790]

I think I’m gonna go for an S1 Pro to do some prototyping and then possible start a small garden with.

[@Redo3D]

I wish the s1 had came out when I bought all my printers I would of 100% gone with that. With that being said I feel I have learned so much with 3d printers because of the v2, and that is valuable for maintaining a farm. Learning how to fix and make things better.

[@jasonharris2790]

@@Redo3D just think where we will be in 5 years with this technology. It has advanced so much just in the last 5 years. Pretty exciting! I borrowed a mono price Inclosed printer and did my first 2 prints through the night. Couldn’t sleep much lol. I know that will pass as I do this over and over and over. Man I would love to see your farm sometime in the future.

[@3DGEOPrints]

Subscribed i approve of this testing LOLOLOLOL

[@RolledIceCream]

Hi can you make a content how you protect your print farm from fire? Thanks!

[@allthekidsareright]

I’m trying to configure my extruder for this. What are the steps and rotation distances?

[@Redo3D]

Rotation distance is 40 for x and Y. I use 3.445 for the extruder

[@footballera-i2p]

I think you need linear rails to get faster and quality

[@opinion_panda]

Does the stock mainboard support pressure advance? I thought the 4.2 boards only operated in standalone l.

[@Redo3D]

They do.

[@ResistCircuitResist]

Wondering how much the direct drive hurts printing speed vs stock, also glass bed vs pei or g10.

[@Mr.Thermistor7228]

Why would it hurt it?

[@ResistCircuitResist]

@@Mr.Thermistor7228 added weight vs bowden

[@alejandroperez5368]

@@ResistCircuitResist you realize the bed weights a lot more?

[@ResistCircuitResist]

@@alejandroperez5368 I do, but that doesn't change the fact that if your hotend was lighter it might be able to print faster or at better quality. I also mentioned pei and g10 specifically for the bed. Are you using a pei coated spring steel sheet, also any change from the glass in terms or speed or quality?

[@164procar4]

The biqu h2 CANNOT handle more than 160mm extrusion, it skips steps for low torque

[@aaveisen]

I have v1 and 200mm is not problem
