SOVOL ZERO/MAX + hotend Creality K2 Plus

The original hotend on the ZERO has good characteristics, but low quality of assembly and manufacture. As a separate spare part it has an unreasonably high price.

At the same time, the CREALITY K2 Plus hotend is available on the market. It is better, has a more powerful 100W heater, a quality thermistor, is well assembled from high-quality materials and has a lower price.

Оnly buy the original K2 Plus model (in a white box)

When installing the K2 hotend, no changes are made to the design of the original head, and the reverse replacement is carried out quickly. You may have to discard the original cover, it will fit, but it will be slightly warped. A good alternative is to remove the cover and mount the cooler separately.

Build of Materials:

1. Screw M3x25 - 4pcs.

2. Screw CSK M3x12mm - 2pcs.

3. Screw CSK M2.5x10mm - 1pcs.

4. Heat-set insert M3x3 - 2pcs.

Optional (Installing the cooler and lower hotend mount on heat-set inserts)

1. Heat-set insert M2.5x3 - 6pcs.

2. Screw M2.5x25 - 2pcs.

At the outlet of the feeder there is a PTFE tube with a length of 16 mm, it must be cut to 8 mm

The K2 hotend has short thermistor and heater wires. You need to make an adapter (the heater has a 2.54mm connector, the thermistor has a 2.0mm connector).

We need to tell the system that we have a new thermistor. Find this section in the printer.cfg file, disable or delete it.

[adc_temperature my_thermistor_e]
temperature1:25

Add a new section to the file with the thermistor data (Note that "adc_temperature" has been replaced with "thermistor").

[thermistor my_thermistor_e]

Perform PID calibration

PID_CALIBRATE HEATER=extruder TARGET=250

Before your first print, be sure to calibrate the offset (the new hotend nozzle is 0.8mm lower).
