Description
- The EMO-25 has a 25cc anodized aluminum reservoir with a threaded collar at each end. The top has a threaded rod, which is how material is displaced; the bottom holds a nozzle, or a nozzle or luer adapter. Industry standard luer tips or needles are available from a variety of sources.
UV Crosslinking
All of our reservoir-based heads can take a UV Array, mounted around the nozzle, or a UV Pen, mounted in another tool position.
The UV Arrays are lower power, and available in 280, 310, 365, 405, or 450 nm.
The UV Pens are higher power, and available in 365, 405, or 450nm.
Loading the Head onto the Printer
As with all Hyrel heads, the following process should be followed:
- Start with a level bed and Repetrel running and connected to the printer.
- Load the gibs on the Head into the gib slots on the Yoke from above and slide the head down into place; the last mm of travel should be done gently, ensuring that the electrical connector seats properly (firmly and completely) into the receiving connector.
- Ensure the LEDs on the print head are flashing - this means the Head is communicating with the Motion Controller.
- Tighten the thumbscrew in the rear, to prevent the head from moving relative to the Yoke.
- If the Head doesn't show up in Repetrel, press and release the RESET button on the front of the printer.
- Once the Head is shown in repetrel, proceed to setting your Z-Zero position.
Loading material into the Head
Loading:
- Care should be taken to avoid air pockets, as this will introduce delay when starting and stopping material flow.
Unloading:
- Unloading is the same process as loading, only in reverse. Tubes and nozzles should be cleaned thoroughly after use.
Default Parameters
Default settings for the EMO are shown on the Cold_and_Warm_Flow page.
Adjustments
The only adjustments needed should be changes to the PRIME and UNPRIME settings, and will have to be dialed in based on how viscous and compressible your material is, and how narrow a nozzle or luer tip you are using.. In dialing in new settings, I usually double or half the settings for both STEPS and TIME, then make another print and reassess.
Firmware
Please see the Downloads page for the current firmware for your heads and your version of Repetrel.
Maintenance
While cleaning your print media from the tube and nozzle after every print is important, very little other maintenance is required on this head. We DO recommend lubricating the screw as needed, with light grease, petroleum jelly, "3 in 1", sewing, or other light machine oil.
