Page 7: Host Software
Host software The host software can be used to perform all required duties on printer, as manual axes movement, heaters performance analysis and setup, placement of parts on printer plate, slicing and running printing jobs. We recommend Repetier Host, being the most complete yet easy to use solution to accomplish above activities, and the fastest way to interface with Repetier Firmware running inside our printer. - Page 8 Host software setup To access Repetier host configuration menus you simply press click on the upper right “gears” icon. You will reach the following menus (shown in English, but you can choose among many languages): Fig. 1: Connection parameters Port: leave the port you use to connect to printer Baud rate: set it to 250000 Other parameter must be left unchanged at default values (see fig.1).
- Page 9 Fig. 2: Printer parameters We recommend to set printer defaults as from above figure. You may want to un-check the last three check boxes if you are using printer in a continuous production setting (avoiding losing time when machine cools down between print jobs).
- Page 10 Fig. 3: Extruder control Above values must be entered precisely as from above screen capture: feel free to choose names and colors, but please be sure to enter correct numerical data !
- Page 11 Fig. 4: Printer shape Be sure to copy EXACTLY above values, especially the Home X/Y/Z settings: failing to do so you could not be able to use your printer! Now if you turn on your printer with the leftmost ON/OFF icon, you will be able to start playing!
- Page 12 Filament The filament is the most important factor of the printing process, therefore you want it to be: • Precise: real diameter (2,85mm or 2,95mm) must be as constant as possible, and within the usual tolerance (+/- 0,1mm) or stricter (+/- 0,05). Remember: use a good caliper (nowadays, there are good digital calipers that are quite cheap) to measure the diameter to pass to the slicing app.
- Page 13 Feeding filament to the printer Fig. 5: Rear printer side Reach the printer rear side, place your spool on the spool holder rod. Fig. 6: Pointed filament end With a pencil sharpener or simply using scissors, make a conical point to the filament end.
- Page 14 Fig. 7: Filament feeders, the one in foreground is locked open (disengaged) Grab the feed lock handle of the selected extruder, pull it up and lock it open. Feed the filament thru the bottom hole in the filament feeder, gently push it inside mechanism and clear plastic tubing, until it reaches the extruder assembly and you can't push t anymore.
- Page 15 Loading filament (during print) When the filament spool is depleted, the loading of a new one is a quite easy process: 1. Prepare the new spool to be loaded, be sure it is the same polymer you are currently using 2.
- Page 16 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 (not too strong to break it...
