    A2 printer only: longest pipe is to be placed on feeder #1 (rightmost, when looking on the rear side). After fitting ptfe piping on each filament feeder, you can mount them on the printer, feeding the piping thru the rear openings, just above each feeder position. Each feeder has a “mandatory” posit...

    After placing fitting ptfe piping on filament feeder, you can mount feeders on printer, feeding the ptfe piping thru printer opening on the rear, above each feeder position. Each feeder has a “mandatory” position: please refer to fig 7 and 8 for respective printer models. Mount all filament feeders....

    When feeders are mounted and wired, you can connect ptfe piping on extruders. Open front panel (to do so, you have to remove four screws using 2.5mm hex key) be sure that ptfe piping is untangled. Front-side extruder is the #1, therefore has to be fitted with leftmost ptfe piping (looking from front...

    Connect the printer using the supplied usb cable. You can connect to your pc or to a printer server. At first we recommend using a pc to better understand basic machine use. Just be sure to route usb cable away from sources of electrical noise (such as power transformers, electric motors, and other ...

    Using the printer with your computer we urge you to use a pc at least at the beginning: once you build enough experience then you will be able to switch to more advanced printing methods (sd card, print servers). Therefore you need to physically connect your pc to the printer (supported os are windo...

We take the chance to remind you that to get best results you should always stock filaments in a dry place (soaked filament makes for steam during ...

    Using a pencil sharpener gets better results. To feed filament: 1. Grab feeding device handle and lock it open using the pivoting ring on the handle 2. Feed the filament into the hole on the lower part of feeding device 3. Push in the filament until it stops, when it reaches the extruder assembly 4....

    Filament removal – idle machine filament cannot be removed when machine is “cold”, as it will be melt inside extruder, therefore to remove it you need to follow those easy steps: 1. Set the extruder at 70% of working temperature (usually almost all polymers start softening at 160°-170° c, enough to ...

    Changing filament type when dealing with different polymers, procedure is a bit different. Start with a “cold” extruder situation: turn on heating for desired extruder, at about 60-70% of the currently loaded polymer working temperature. Release the feed mechanism and lock it open. Start pulling (no...

    Printing printing process can be started and managed in three different ways: • connected to a pc (using repetier host) ◦ pros ▪ real time monitoring of temperatures graphs ▪ almost real time visualization of the layer being printed ◦ cons ▪ pc can't be turned off ▪ if pc has not enough power, some ...

    Print removal when printing process is completed, remove the printing tray and let it cool down. Once printed part is at room temperature, it will be easier to remove from the tray. On thick parts, without fragile zones, hitting the part sideways will pop off the part from the tray. Be very careful ...

    Fitting the soft polymer feeding unit (spfu) used when soft filaments are needed (that are really difficult to use with standard feeders), the sfpu feeder lets you use any elastic filament available for fdm/fff printers.

    9. Now, using a small lens, look carefully at the printed part: seek the point where the “align_line” is precisely in the middle of the printed “channel”, both in dx and dy sectors. If machine is ok, the line should be at the middle of the channels at dx0 and dy0 positions. 10. If you find the middl...

This approach ...
