The MK1-250 is our primary workhorse print head, and works for standard (rigid) 1.75mm filaments which print at temperatures up to 250°C.
This includes the following materials:
- ABS (Acrylonitrile Butadiene Styrene)
- Flame Retardant ABS
- ABS - PC Alloy
- Conductive ABS
- Smart ABS
- HIPS (High-Impact PolyStyrene)
- LayBrick
- LayWoo-d3
- Nylon
- Taulman 618, 645, 910
- PC (PolyCarbnoate)
- PET (PolyEthylene Terephthalate)
- PETG PolyEthylene Terephthalate Glycol-modified)
- PLA (Polylactic acid)
- Conductive PLA
- SS PLA (Stainless Steel infused)
- PP (PolyPropylene)
- PVA (PolyVinyl Alcohol)
- T-Glase
Description
- The MK1-250 is fed filament from the top, through low friction tubing (2mm ID, 4mm OD) seated into a 4mm pneumatic fitting.
- A cover plate maintains pressure, via a spring, against a rod with two bearings; these bearings keep the filament pressed against and centered on the gibbed (toothed) portion of the drive shaft of the stepping motor.
- Beneath this, the filament enters into a 2mm OD PTFE guide tube, which leads the filament to the brass nozzle, with which the PTFE tubing mates.
- At the nozzle, heat is transferred to the filament, whereupon it is forced out through the brass nozzle.
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.
