Figured while I was waiting for parts, I start up one of these in case anyone else might be interested. I am planning on converting the Y axis on my E3 to awd/dual motor, and plan on building a heated chamber for it based of Derra's https://discord.com/channels/167661427862142976/1270593788200489043. I already have bought another E3 to use the bed as a chamber heater. I'm not shooting for anything crazy in the high temp department, only upto around 60-65C with what I already have on hand.

Current State of my Ender 3v2
I bought it and it already came with the typical fixes, creality metal tension arm and CR-Touch
I've since added dual z and a tz hotend, dual 4010s, and converted the bowden extruder to direct drive.
The last major thing was I modded the v4.2.2 mainboard to have UART by deleting the screen since its not useable with klipper anyways (was using MRISCOC's build of marlin previously)
Stock Motion System
20,000 Acceleration 400mm/s Speed (absolute hardware limit)
Actual printing saw 10,000 Acceleration 400mm/s

#

this was my usual orca profile, its practically a 1:1 of a bambu a1's speed tab minus the travel speed and first layer, i've since been experimenting and think i've found a new profile thats stable, that being the second image

native comet Jan 15, 2026, 7:54 PM

Validating the new profile and hopefully not seeing a layershift on y comfycozy

not the extruder T.T

#

out of curiosity how much did u pay for the cr422

native comet Jan 15, 2026, 8:49 PM

#

For what it's worth it's still able to keep the flow up to 25^3 before the 60w heater has no more give

Damn it layershifted in the same spot 😂

#

#

Went back to stable 10k profile and is fine, gonna hold off on more speed till parts come in hopefully next week

stoic saddle Jan 16, 2026, 2:08 AM

#

native comet Damn it layershifted in the same spot 😂

That amount of layer inconsistency tells me your belts could use proper tensioning

#

Which could also be a cause of layer shifting

#

Layer shifting is either a belt skip or a motor skip and the layers being wobbly like that tells me your belts are pretty loose

native comet Jan 16, 2026, 2:10 AM

#

ShockedPiko I'll give them another look at then for tensioning cause it doesn't do the typical motor skip sound

stoic saddle Jan 16, 2026, 2:10 AM

#

Also underextrusion can contribute a lot to inconsistent layers with the speeds you’re going

#

A Mk8 hotend is not at all designed to push that much plastic

native comet Jan 16, 2026, 2:11 AM

#

It's a tz

stoic saddle Jan 16, 2026, 2:11 AM

#

I’d still test it to make sure you’re not underextruding

You’ll need a pocket scale that can be accurate down to hundredths of a gram

But chances are unless you’re cranking the temps on your hotend you’re gonna be underextruding even with a TZ

native comet Jan 16, 2026, 2:46 AM

#

ah yeah, looks like its time for an extruder upgrade LOL

stoic saddle Jan 16, 2026, 3:28 AM

#

A direct extruder with a nema 14 definitely wouldn’t be a limiting factor for extrusion

#

Though I guess it is direct drive and doesn’t have a gear ratio for added torque

native comet Jan 16, 2026, 9:43 PM

#

I'm not entirely sold that the ceramic heater I have is 60w or it's already dying since it has a hard time keeping a flow rate of 12 above 220c, so I've ordered an 80w and a bmg gear set

rigid parcel Jan 16, 2026, 9:44 PM

#

60W heater is the sweet spot

#

i couldn’t fine one so ended up buying a 80W one

#

but your limitation is probably the extruder there

native comet Jan 16, 2026, 9:45 PM

#

Gonna build a Sherpa heavy with the gear set when it comes in

#

On that note, is it fine to use round or o shafts for the extruder?

not a clue sry

holy crap its 260mm of travel on y now

native comet Jan 24, 2026, 12:52 AM

seems like 20k 500mm/s is working well on the dual extruder motors on y axis, no difference in microsteps after 30 iterations

A lil demonic sounding though 😂

native comet Jan 24, 2026, 6:50 PM

Hmm so I'm test fitting the Sherpa heavy and unfortunately it looks like my 42-34 motor is too large to fit as a direct drive extruder and severely limits my x axis and z axis movement, and I don't feel like spending more money on another motor, so I think I'll revert back to a Bowden setup

#

I could flip it so the motor is on the front but I don't know how wobbly it'll get being unsupported

native comet Jan 24, 2026, 8:42 PM

#

This feels like it'd be terrible for input shaping lol

stoic saddle Jan 24, 2026, 8:46 PM

#

native comet This feels like it'd be terrible for input shaping lol

Why such an overkill extruder?

#

Sherpa heavy is the kinda thing you use when you have a super rigid printer that can handle that much weight and needs it to push a ton of plastic

#

Something like a Sherpa mini would have been plenty

native comet Jan 24, 2026, 8:51 PM

#

It's just what I have on hand

native comet Jan 25, 2026, 1:58 AM

#

NVM the tolerances on my extruder housing sucks, gonna use the spare bmg I got an do Bowden for the time being

native comet Jan 25, 2026, 4:28 AM

#

i think thats the fastest ive ever done a pid tune on the hotend thinkies 80w heater go brrrr

#

dont mind the temps on the left of the graph, had a kink on the thermistor

native comet Jan 25, 2026, 5:02 AM

#

Z tilt works now comfycozy

#

What I want to do next is design the enclosures for the two main boards and power supplies so I can clean up the wiring cause it is an absolute dumpster fire right now

#

I also should probably tape the 5v pin on the cable going to the micro4 because I think it also suffers from the same issue as the v4 board does with power back feeding through the USB port

stoic saddle Jan 25, 2026, 5:59 AM

i was unaware that i could just clamp the bmg onto a v6 hotend, my tz e3 comes with a voron/v6 collet feelssobman im already done calibrating, but i'll still run with the bowden for now since i need to print parts

native comet Jan 25, 2026, 10:08 PM

#

Y motors don't like 1.2 run current for prolonged use :( gonna back em down to 1a and see what the new max acceleration and speed is

native comet Jan 26, 2026, 8:54 AM

#

This is just some late night thinking, while I do have the means to get this project done, I don't have the space or time while in uni so I think I'll put the enclosure on hold for now (or be more reasonable and just buy a abs capable printer like a q1p or q2). What I think I would like to do is leave my v2 as it is after cleaning her wiring up a bit and designing a new integrated electronics enclosure that'll sit between the extrusions like the original one but account for my extra mainboard and return the power supply to its original location. Besides my time holding me back from committing to the projects I also have my safety concerns and the safety of those around me. So with that in mind I'll be changing this to just outfitting my budget e3v2 and I would like to resurrect the e3 pro I got for parts so I would at least have 2 printers (kind of miss having a spare printer lol) so here is the shell of what I'll try and get up and running after wrapping up the v2

I did some dinking around with the v2 since I'm tearing the hotend down to use the parts for the pro, I gave tmc "autotune" a try, looks like it just has presets based on motor specs but they seem to do a good enough job. Motors are running cooler and able to sustain slightly higher accels, but it's also a cold night. Gonna give err the beans again tmr and continue prepping the pro because I believe most of my parts should show up this weekend (hopefully)
