Hi,

I bought a Kossel 3D printer DIY kit from Amazon by AnyCubic and have been able to follow most of the instructions, however I’m confused about a few parts and wanted to seek help.

This is the printer I bought: https://www.amazon.com/gp/product/B019VSIANU/ref=oh\_aui\_detailpage\_o00\_s00?ie=UTF8&psc=1

If you know answers to any of these questions, please post

1. So, these parts came with the assembly kit but I’m not sure what they’re or where they should go - http://imgur.com/ajKKc5M

2. This said 3D printer accessory but I’m not sure what the purpose of it is - http://imgur.com/26nXgvP

3. Another part that I’m not sure how to use - http://imgur.com/brcwWmX

4. I don’t know how to connect the power supply to the printer. This is what the power supply looks like - http://imgur.com/Gq2ge8n, and this is what the possible connections on the printer look like - http://imgur.com/45jj0WN, http://imgur.com/cHRnmaQ (I can post a clearer image if needed) (will eventually cable manage better). I do have a 3 prong plug and think I know how to connect the power supply to the wall outlet - but not to the printer. These are some of the cables they sent (if it helps) - http://imgur.com/ZkkxhOw

5. Lastly, this is the heatbed I have and wanted to know if it can be connected to the same power supply (the power supply is AC) - http://imgur.com/8xj9NP3

6. I am not sure what this adapter is for - I was able to connect the wires without it - http://imgur.com/b5V4i1L

I’ll highly appreciate help!
Thanks!

  1. This is the spool holder. It is stand alone from the printer. Assemble those four parts together.
  2. This is the wire wrap. Wrap it around all the wires going to the effector (fans and hot end wires).
  3. Use this with the spool holder from 1. Insert the tube through the filament spool and put in the cutout of the spool holder.
  4. Connect the wall plug cable wires to Live and Neutral (Brown to L and Blue to N), green and yellow to the earth lug (the symbol in the circle). Make sure the wall plug is NOT plugged in when you do this (obvious but needs to be said). Using that red and black wire, connect the red to V+ and the black to COM, with a heated bed I think you need to connect two pairs of red and black wires. Connect the other end of the red and black wires to the blue terminals on the gorilla PCB. If I remember correctly its the 4 blue terminals furthest away from your hot end heater connection. It should be labeled Vin+ and GND on the silk screen of the PCB so just double check. The red goes to the Vin+ (or whatever) terminals and the black wire goes to the GND terminals.
  5. I’m not 100% sure on this one. I think the anycubic heat bed is 12V (NOT AC), connect the red and black wire from the bed to the terminals next to the hot end heater connection. I think the white wire from one of your pics is the thermistor for the heat bed, use some kapton tape to tape it securely to the underside of the heat bed. I’m not sure where to connect the heatbed thermistor to the Gorilla PCB though (guess; next to the hot end heater thermistor).
  6. You dont need this, the anycubic LCD connects directly to the Gorilla PCB without this interface PCB adapter.

Good luck.

Again, be cautious with the AC power! There are numerous PSU covers on thingiverse. I suggest you print one and cover up those terminals ASAP!

Hello,
nothing complicated going to excuse the grammar order but use google translator. first graduation question for the components of the first application are provided for the filament spool and then are to be assembled together with the tube therefore the demand 1 and 2 are from asemblare sunglasses because they serve to support the filament spool

The answers given by jasonza are all correct, However I’d like to chip in regarding point 5.

The machine is 12VDC, the power supply converts 240/110VAC to 12VDC.

If you aren’t going to use the heated bed the small black power supply is good enough to run the machine.

If you ARE going to use the heated bed you’ll need to use the bigger PSU as the additional power required to heat the bed would trip the smaller PSU.

I bought my kossel from aliexpress and it’s a slightly different model but I’ve attached the heated bed instructions that came with it. The Power supply looks to be the same but the controller board may be different so please be aware that as these aren’t instructions for your printer they are used at your own risk.

The white wires are definitely the thermistor wires for the heated bed and will be needed to return the bed temperature to your machines controller board.

Thanks for the great comments. Regarding #4, I don’t see a blue terminal labeled Vin+ and GND.

The corner of the PCB next to where the power supply would plug in (I didn’t receive the small block power supply, only the

larger one) has blue terminals labeled “- 5A +” and “- 11A +”

Is one of those pairs where to connect the power?

Yes; connect to the 11A +, -. + is red, - is black from the PSU.

Here is a document I received from Anycubic about the same time as your reply. These instructions don’t make it clear how to attach the glass to the hot plate. Is that double sided tape?

No; its Kapton Tape. Don’t know why they would show a picture like that?

There are designs on thingiverse to hold the glass and the heatbed to the frame. The glass can just rest on the heatbed (but obviously mustn’t move about).

I don’t have a heatbed on mine so I’m guessing (educated guessing I like to think).
