no print cooling fan?
Yeah, the PLA sure gets soft during prints… I didn’t print fan shroud yet, currently only have the tiny end fan on H2S. Reason is am using old carrier still, plan to print fan shroud after updating carrier first.
Since the printer seems too be a never ending project, before any more upgrades, am spending time wrapping up sharing content captured first. May have figured out an interesting way for people to watch the build however they want…

That discord picture really messes with me. Why is it mirrored?
Also, the fan shroud I have on mine works with my new carrier.
Lol, yeah Discord/social apps simulate mirror behavior when previewing. Nice benefit is that the external tags end up being readable.
Currently uploading 200 part build series that’s 10x playback speed. After that’s done will upload another set of 200 encoded for audibly understandable playback rate…
Working on custom player that pulls everything together. An experiment that could be great, or a waste of time, will see…

Work in progress, still uploading 10x content… Planning to create a better player experience.
Edit: Sharing content in a more accessible form…

149 videos? Wow. Watching those would take me longer than assembling the MK4. 
Sometimes I really envy you guys and the time you have for your hobbies.

@Jonathjon just shared that there’s a V2 of BTT’s Smart Filament Sensor .
The sensor seems to be BIQU’s newest released product, with a BLTouch competitor Micro Probe V2.0 For H2 Series Extruders as the next most recent. Assuming the reviews are good, would’ve tried these parts out if building today.

BIQU H2 REVO Part Cooling Fan Duct
After digging around, finally got around to adding a fan duct, with M8 grub screws to seal holes the M3 bolts are fed through…
Shared on Printables…
Designed the duct to work with and clear @probrwr’s BLTouch mount. I still need to upgrade to Mike’s latest rail mount.
Heavily based on 396716-biqu-h2-revo-part-cooler-5015-bl-touch-mount, but also steals ideas from several other models I reference on printables.
Created this after not finding what I wanted :
- Must allow full motion of tensioner arm, which should be comfortable to access.
- Must enable dissassembly for dealing with filament jam/clogs.
- Must leave extruder stepper clear as possible for heatsink(s).
- Must leave front right holes clear for mounting stuff.
- Must be clear at the front so nozzle can be clearly observed.
- Must ensure Fan Duct placement is compact and not sticking out too far forward. I have limited front room due to my MP3DP’s polycarbonate lid.
- Max air flow. Partial success here, I widened the opening, but could have done more to max flow.
- Nice to have clip holes for custom grill to mount…
Parts
Printed 0.6mm nozzle, 0.32mm layer height. 0.2mm layer height would be better, especially for the grub screw threads.
- 2x M3x25mm bolts and nuts
- 2x M8x4mm grub screws/bolts (or shortest you can find, am using M8x8mm from my parts stash).
Klipper firmware config
Updated klipper/printer.cfg with…

Assembly|Problem > Mount XY Belts > Pulley orientation
problem: Noticed belt wrapped around my Right XY stepper is riding up and down when the hotend moves around. Belt seems to be sloped at an angle, stepper seems too low, or…
cause: Dug around for MP3DP pics, and only just realized Stepper pulley orientation is supposed to be different on each side…
Don’t do this…
fix: Got the left side correct, but need to flip my right side. Should instead do this…
Expected Assembly :
- Left Pulley should have Grub screw high.
- Right Pulley should have Grub screw low.

Nice catch! I think I have one of mine wrong too. I need to go look at that.
DAm…I really need to stop screwing around and do some docs updates. Sorry you guys are having all sorts of issues with the printers.

Nothing at all for you to be sorry about. Not one of my issues have been anything but self inflicted. I’m chasing square now. Not knowing how far I need to chase it. Into bed skew corrections now LOL

I mean, you explicitly stated that you were not going to officially support any printer builds, and here you are, helping everybody.

Am astounded by how much you do. Seems like MP3DP’s not paying the bills, so relying on contributions from the community makes sense to me. Despite embarking on IDEX, am still working on something that’ll help MP3DP builders…
Personally, I view the MP3DP topics/posts as a good thing, we have bunch of people who like to make and solve puzzles/problems, and then continue to tinker/improve things. I appreciate how much people here collaborate and elevate one another to maximize value from a project you generously shared.

After looking at the FluidNC Wiki… I realize how valuable docs are and how lacking mine is. I need to spend time on it. After switching computers, I have not set up my git stuff again, editing just on github is not good enough.

Friday fun… Does this snippet look like Plaid to you (despite not being O.G. red and orange)?

Which Project’s docs are most behind where you’d want them to be?
Already got solution in mind (e.g. wikidocs), or looking for something? Personally, I like the mkdocs, and git. Is Markdown vs wysiwyg the main challenge, or something else?
Is there a benchmark shining example of what you’re striving for?
