Comment on Ender-3 V3 Plus for cosplay props

rudyharrelson@lemmy.radio ⁨2⁩ ⁨months⁩ ago

Agreed on the Ender 3’s needing some tinkering. My wife got me the Ender 3 V2 a couple of years ago for Christmas and I like it a lot, but I spend more time troubleshooting it than actually printing stuff.

I like to tinker, but the Ender 3 V2 takes advantage of that fact.

Any recommendations on part upgrades? I’ve upgraded the nozzle and the extruder on mine (the stock, plastic extruder cracked badly last year and I replaced it with a full metal one), but it is still very unreliable. Prints are always failing due to adhesion issues even if I use aftermarket adhesives like MagiGoo on the build plate.

Best upgrades for me was the following in order of overall impact

Klipper Skr mini e3v3 board Silicon bed spacers Klackender mod by KevinAkaSam G10 build plate Orbiter extruder and dragonfly hotend for direct drive Belted Z mod by KevinAkaSam

More recent EBB36 canbus for the tool head mainly because it frees up some ports on the control board for other things like my Nevermore.

For overall quality and reliability the following have the biggest impact.

Ensuring the physical frame is as square as possible. As well as adjusting and shimming things such as folded aluminum foil under the Z extrusions to get them square with the base.

The board and Klipper are huge since it makes it easier to use the klack probe (Klicky for ender) and the silicone spacers allow me to dial in the screws with adjust_screws.

And skew correction because my X gantry is twisted (tested that on granite counter top) and after I’ve done everything else to ensure it’s physically right i still had to work around some of it with software.

Now I can just fire it up and print PLA, ABS (it’s in a grow tent enclosure), PETG and TPU without any issue.

The g10 plate works great with all of them, Klipper can compensate for any warping, build offset as long as the screws are properly adjusted (which I test every couple of months or after I’ve had a print that really didn’t want to come off.

I’m building a trident myself right now and I’m using the “Frankender” to do it with really great quality results.

  Thanks a lot! I’ll look into the upgrades you mentioned and try my luck. Here’s hoping I can get it back up and running without too much work

The best upgrade I made for the Ender 3 for adhesion was a PEI coated build plate. I don’t know the specs of the V2, but the brand I went with was “Wham Bam Systems” mine didn’t have a magnetic bed so I had to purchase the kit with the magnetic plate, and stainless steel PEI coated build surface. It was nice being able to pull off the plate and pop prints off of it. Be careful printing PETG on PEI it can fuse to the PEI

If the V2 has some sort of leveling system make sure it’s working correctly or the PEI sheet isn’t really going to help. I had so many failures where the print head crashed into the sheet and gouged it. I added a BLTouch probe and flashed the firmware and it got much better.

  Thanks a bunch; I’ll check out the PEI coated build plate.
  
  I’ve contemplated getting the BLTouch probe for auto-leveling, but I don’t think bed leveling is the root of the issue; I’ve leveled the darn thing about a thousand times by now
