2. Nozzle getting in the way Vertex K8400

Vertex 3D Printer Vertex - Issues while printing
1

Hi Guys,

I have a Vertex K8400 with 2 nozzle. It is a little odd problem. I just got my printer and 2. nozzle, because of bad driver board, was out of function. I used until now 1. nozzle until I got my driver board.
Now I have installed the board and 2. nozzle print beautifully.
My problem is now: When I start a new print with 1. nozzle, after print of 1. layer, 2. nozzle come in the way and tears the print from 1. nozzle. How can I solve this problem?

Is it because som filament sitting on tip of the 2. nozzle and dried. What can I do to help this problem?

I would appreciate your advice.

Regards,

Hello Ziglu5,

you max have a look at the manual, especially on the chapter for two nozzle printing http://manuals.velleman.eu/article.php?id=25.

They call it ooze shield, which should prevent exactly these effects. It is described for Repetier, you may check for similar mechanisms in other slicers.

Good luck.

I heat up the second nozzle, even if not used.
Not now any more since I moved to CYCLOPS from E3D

After completion of a print job, just clean the nozzle with a kleenex.

During cool down, you will see some plastic oozing until the temp drops to some 150 degrees (@ PLA) - you can still remove the droplet at that temp & you won’t get a new one, as the plastic will be too cold.

Works perfectly on my printer. :slight_smile:

Edit: if you notice the droplet after the printer has cooled down - hook it up to Repetier Host with the USB cable & activate the heater. Set the temp to some 150 degrees & you’ll be able to wipe the PLA off the nozzle, without forming a new droplet.
