FLsun V400 Effector Dis-Assembly ~ Assembly

Hello Folks:
I hope you are all doing well ...
This is the video everyone has been waiting for !!!
Although my little girl did not have to do the videography for this one, I still have to thank her for keeping an eye on me and reminding me a couple times that I did not have the video turned on !!!
BIG shout-out to Kaili, my partner ...

You are now a 2x savior. My V400 had another massive clog, encasing the entire hot end. I cleaned it out but the wires were in a filament blob and they broke. Likewise, several of the screws were unremovable. FLSUN sent me replacement parts and I appreciate it although the parts did take almost three weeks to arrive. Anyway, thanks to your video I reassembled the whole effector. There's just one thing... You know those 6 ball joints on the mounting plate? The set screws holding them in are so tight on the original, I stripped out 4 of them! I kid you not. Why they didn't just include a complete mounting plate is beyond me. I think I have to drill them out and then find replacements locally or via Amazon. Joys of 3D printing.

Big Smile: Yes, I have had this issue as well. Those set screws seem like they are using lock-tight. I agree that you will have to remove these screws by brute force !!!

[@braddahr]

@@dennisgignac5103 I did drill them out and transferred the ball joints to the new plate. I found some small bolts that matched the size. The printer is back up and running!

Great breakdown video. I enjoy my v400 but found that my Thermistor is stuck in the heat block. But at least they gave me a spare part. :-{ There was another issue, so I purchased a new effector as I can use the original for spare parts since there is not much on the FLSUN site for parts for the V400. For the price, I would have expected the machine, to have better build-quality screws. Found the screws are made of soft metal and easy to strip. Over time, the motion of the effector caused the hotend to be loose and need to be tightened and that is how I come to be here. Keep up the great work Dennis. I enjoy your channel.

Thank you

Thank you so much for all these tutorials, I’m new to printing with a v400 and I really appreciate all you do

I have had my V400 for 8 months now. Since then I have had the MCU burnout as well as the effector control board. FLSUN did replace both. Also have the FLSUN enclosure. I just purchased a second one and am making parts on the original for a custom enclosure. Have since upgraded the part cooling to 5015 fans. Also both will be outfitted with stepper motor cooling using a temp controller. An ADXL345 input shaper is a must. Since the upgrade to the cooling and the input shaper on the original machine my prints are now coming out fantastic. I print the inner and outer walls @280mm/s and Sparse infill @350mm/s. Internal solid infill @250mm/s. I am slowly increasing speeds BUT very aware that the type of filament is the linchpin. Using PLA Plus at this time. Delta's are a unique printer and are not for everyone BUT with a bed that does not move first layers problems are a thing of the past compared to a bed slinger. Thanks for this detailed video once again. Cheers.

Hello Jeff: You are right, these printers are very friendly to a beginner. BUT, sounds like you truly know how to get the most out of these printers !!! Others could learn from you...

[@trevormcintosh9866]

I've been lucky enough, I have not had to take one apart yet.

Once again thank you for the help.

Anytime !!!

Thank you so much for this guide. Good luck with V400!!!

[@braddahr]

Thanks very much for this. Today I had the worst filament blow up ever. Your video was very helpful with the disassembly.

Great job. hanks for taking the time.

[@tonykyle2655]

Guess what. I suffered a head crash on Saturday and it being the heat break. I've ordered a full replacement as well as new nozzle kit. I plan on doing the replacement upfront to get the printer back into operation and then replace the nozzle kit so I have a replacement.

[@dennisgignac5103]

It is definitely a learning experience !!!

[@tonykyle2655]

@@dennisgignac5103 Question. Do you have a video for replacing the nozzle kit? Things went south with the full effector (won't go into detail but a confusion with a store on AliExpress). I got the nozzle kit but would prefer not having to take the effector off the printer to replace the nozzle kit.

[@Maic_Mensink]

Great Tutorial! Thank you very much! The Fanduct are very grued... ähm... glued. 😉 I´ve tried it many times but i´m not sucsessfully. 😢 The original does not hit the nozzle exactly and overhangs are printed rather poorly. There is a model on Printables (291550) that is supposed to work much better but I can't get this glue off. 🤬

[@booboofinger2595]

Thank you Sir! All of your V400 tutorials have been helpful. I'd like to replace my V400 nozzle however they are never in stock. Someone on youtube pulled the nozzle upon assembling the delta for review and mentioned that the 400mm speed is achieved partially because of a special nozzle that FLsun developed specifically for the V400 and it differs from generic 4mm nozzles. Any thoughts?

[@dennisgignac5103]

Hello BooBoo !!! Yes, they are certainly different because the entry point of the nozzle has 2 entry points that splits the filament and allows for more flow. I have a few here in the USA. Just message me in FB. Another possibility is this Bondtech: www.bondtech.se/product/bondtech-cht-volcano-coated-brass-nozzle/

What with the set screw?? Did get that information about why there shouldn’t be ? I only found one on the heater. But still can’t get both off

I noticed you have a fan pointing the wrong way 28:31

Thank you very much. You are absolutely right !!! Very good eye...

[@warriors475]

thanks for the video it was great can you not replace the heat block without taking everything else off ???? i know you was showing a strip down of the whole unit

[@dennisgignac5103]

You will have to remove the two longer screws with the tiny tube on them and then the two set screws...

[@footwearology]

Why are you not showing how you take it off in the first place? That does not seem to work for me

[@SergioGonza99]

Turbo fans (those lateral fans) must be always on during printing ? Or they turn on /off sometimes?

[@dennisgignac5103]

You can control them from the V400 Pad...

Thanks Dennis, what information is needed for you you contact FLSUN on my behalf? I have switched the wires on the adapter board and the lights still don’t operate. I will send you the information if you tell me what you need. Thank You you have great videos.
