Check out my Z brace for the frame gantry on the i3 mega

by Thr333DDD

Seems like the i3 mega has died down quite a bit since it's inception. Are there still people modding their printers? Mine is going through some major mods at the moment. Check back later for more design as I continue to add the mods.

Here's my Z brace mod:

by Mauluok

Think I fried my board upgrading to a Noctua A4x10 fan for the hot end. Found a thread on this seems to be common wish I had found it before upgrading. think I've found the transistor labeled J3Y https://www.digikey.ca/en/products/detail/IRLML2502TRPBF/IRLML2502TRPBFCT-ND/812502?itemSeq=376607217 but is the little one to the right that I think used to be labeled "01X" that looks blown too anyone know where to get this one?

Thanks.

by Metrolan

Hi!

Both connectors of hotend cable (green) are burned. I'm looking for a replacement cable or at least, a place to buy the connectors.

Searched Amazon, Aliexpress, Banggood and ebay. Only found in ebay.de, but vendor didn't ship to my country (Spain).

Anyone can help?

I am planning to add a Raspberry 3 Pi to my Mega i3s Printer.

Has anyone installed one inside the base, or do they need to be outside?
Thanks in advance,.

Anycubic axis jam inconsistent

by dansleeth

https://youtu.be/jwf6TSWgAk4

My Anycubic i3 Mega has started to intermitantly jam at the same point along the x axis, but inconsistently.

The carriage is smooth along the start of the x axis (when I manually push it, printer turned off) until about half way and then it hits an invisible wall and becomes hard to push. If you put a fair bit of pressure, it feels a little like it skips, but then it is okay along the rest of the axis.

On some prints it is fine, while on others I can come back and see that the x-axis has not moved for several minutes and there is a massive blob in a line where only the y-axis has been moving.

Could somebody make some suggestions of what it might be and what it definately isn't...

  • Belt doesn't look terrible.
  • Can't see the teeth on the motor and that looks like a pain to get to
  • Stepper motor's internal gears?
  • Can the drivers have a physical affect?
  • Bearings?

Thanks in advance

Anycubic Crimp Connectors Hotend Cable

by johmeller

Hi @ all

I've got a faulty wire in the cable leading to the hotend of my MegaS. I wanted to switch out all the wires but found that none of my crimp connectors fit. I've tried the standard Dupont and a 2.54mm JST-connector. I can't get neither of them into the green terminal that you plug into the hotend.

So, here's the question: could anyone post a link to suitable crimp connectors?

Since I'm not sure that I use the right terminology I'll attach an image of what I believe is called crimp connector :-)

All the best

After 2 days of printing, no filament coming out of nozzle

by crankypants

First, let me say that I am relatively new to 3D printing. I managed to successfully print some smaller items (mostly cosplay gauntlets, armor pieces, etc), but my attempt at taking advantage of the height of the printer hasn't been great so far. I am trying to print a Bo-Katan helmet. I purchased the file on Etsy, and based on the comments, I am sure the issue is user error. On my last attempt, things were going fairly well and then when I checked on the printer, the nozzle was still moving, but was a couple inches above where the print was -- it stopped putting out filament. The temps looked okay on the display, and when I tried to manually push the filament through (holding the trigger by the extruder), it went through fine.
What did I do wrong? Was there just a clog, and it was bad timing that it happened on day 2 of the print? I am going to try to salvage the print by printing the remaining top part of the helmet, and gluing together.
Also, my support looked a little iffy, and there was some weird stuff going on at the front of the mask. I'm guessing my support infill was too low, but if anyone has ideas to point me in the right direction before I try this again, that would be much appreciated. The only thing I could think of is humidity. It was pretty humid out during the print, but I was periodically running my ac to try to keep things at a comfortable humidity. I haven't had this issue before, so not sure how to correct it.
I am attaching photos of the whole print (I had lowered the nozzle to try to find out the coordinates where it stopped printing, but it was higher when I noticed the problem), the funky support area, and the spot at the front of the helmet that didn't look right.

i3 mega seeing card but not seeing files

by cam2363

My mega sees that an sd card is inserted, but doesnt see any files on the card.

I tried:
Formatting card
having only 1 file on
changing to a different card
restarting it
Re seating sd card cable

and I get nothing. It was working earlier today, but it just quit seeing files. Any ideas or thing to check?
