Biqu h2 vs hemera5/7/2023 ![]() ![]() Is my understanding of these correct? I currently have an Ender3v2 with a direct drive setup and am curious if LA or PA would be considered better today (2022)? From what I understand, my 4.2.7 motherboard is not compatible with LA due to its stepper drivers, and I am trying to determine if I should move from Marlin to Klipper and use PA, or whether I should upgrade my motherboard and use LA in Marlin. This should also prevent under/over extrusion in the print similar to LA, but where does it differ from LA? PA also seems to alter the extruder flow rate based on the movements. The effect of this would be prettier corners and z-seams LA will alter the extruder acceleration movements so that the extruder can keep relatively the same pressure while printing. If I understand what I have read correctly, then: There is also a fan mounted BLTouch mount on there, but it’s not centered, and you have to look in the comments to find the offsets.I've been trying to do some research on Linear Advance (LA) on Marlin and Pressure Advance (PA) on Klipper, and from my understanding the technology behind each is different, although also similar. it’s an easy fix, but I’m working on a SKR2 Electronics box for the MP3DP V2 since i plan on using klipper with dual Z endstops (probably a derived part for the right side somewhere, or a simple mirror of the RZ motor mount and a drilled hole on the YZ side…lol).īIQU H2 complete Kit for B1 single 4020 Fan - V2.1 by DaStivi - Thingiverse my block is not only rectangular, but the nozzle isn’t centered. With the sock and printing it in ABS/ASA I don’t think it’s that big a deal, but if you do decide to print 500C you’ll probably need it unless you get the pheatus hotend since that’s what it was designed for. ![]() The cooling fan I’m currently using is someone else’s design, but I had to file around the profile of the fan to reach the mount screws, and as mentioned earlier, i wanted to make it not touch the hotend. ![]() I should have my design done by then, even thou I’m playing the game of micromanaging millimeters at this point… lol I did it anyway, so most of what said below no longer applies (except the need for edits)īIQU H2 Adapter Parts for V1Engineering MPCNC V2 Shipping is 15-20 days, but I probably won’t have the rest of the printer done before then anyway… I am hoping to use your cooling fan and BLTouch mounts when available. Other than the Sherpa Mini, it’s just about the lightest direct drive out there.īe warned, the kit comes with 24V 35mm fan and heater, so if you’re going 12V you’ll have to source those on your own, which is another reason why I stuck with the DragonFly.Īs for my mount, I still have some wire pinching issues, so I have to modify the top and bottom brackets a smidge more, but I’ll update here when I post those files. I have a spare that i might see if it’s plug-n-play, but not too concerned at the moment. I currently run the dragonfly on both my Mega Pro and Voron V2.4 and love it. It’s a fantastic plastic pusher that’s compatible with V6 nozzles (which also means Bondtech CHT compatibility), so I don’t have to buy into yet another ecosystem, and some versions come with the dragonfly hothead from phaetus, but the one i have is the blockier pre-merger type so socks might be an issue. GAME OVER For Hotend/Extruder Design? - The Biqu H2 Direct Drive Hemera Alternative - YouTube I first heard about it from Design Prototype Test on YouTube: I originally wanted to put it on my An圜ubic i3 Pro, but i would lose about 5mm on the right side since the Z is behind the vertical gantry, instead of in front like every other i3 clone. ![]()
