Graphite heatbed Bed for Creality K1 Max 3D printers

  • No warping: bed stays super flat at 120C as well as at 60C. No need to heatsink the bed for long time like aluminum beds.
  • Maximum bed temperature up to 130C compared to 105C stock bed.
  • Over 30% lighter than aluminum.
  • Works with Eddy current sensors (Cartographer, Beacon, BTT Eddy).

Included:

  • Pre-assembled Graphite Bed (with 1000W heater, magnet, grounding wire)
  • 4x M4 Bolts and nuts
  • 4x Springs (do not use with stock bed probe)
  • 4x Metal spacers (for stock bed probe)

Upgrade results from buyers after sanding down the magnet:

  • Zero warping

    These beds are much flatter than the stock ones and the main difference is that they keep the same shape at any temperature. These beds have been tested for over half a year at temps from 50C to 130C.

    That means: no heat soaking, no layer issues and first layer issues caused by bed warping.

  • 130C Bed Temperature

    These beds can be heated up to 130C, compared to 105 stock bed which warps like crazy over 100C. Heater has inbuilt 150C self-recovery switch for safety. You can use 115-120C bed temperature for better first layer adhesion and to reduce warping. Also, an add bed fans to help with chamber heating.

  • Graphite Flatness

    Every single graphite plate is tested for flatness with precision tools. All graphite plates are in the 0.1mm flatness range.

  • Bed Flatness

    The main advantage of this bed is zero warping. You don't need to waste time heat soaking the bed to avoid related print issues.

    The bed mesh depends on many things: z assembly, bed plate, bed magnet,
    gantry, probe, build plate etc. With all these factors you may have
    from 0.1 up to 0.5mm flatness mesh.

  • Flat mesh ≠ Perfect first layer

    Super flat mesh doesn't mean you get perfect first layer. And the other way around, not perfectly flat mesh doesn't mean you can't have a perfect first layer. We have a printer with 0.07mm range mesh and the first layer is terrible, because of the twisted gantry. To fix your issues with first layer we suggest using Axis Twist Compensation on both X and Y

  • Tested with Cartographer Probe

    Every single bed was tested and meshed with Cartographer probe after assembly, which is much more accurate than stock PRTouch. All meshes are 0.1-0.25mm flatness.

    But, again, mesh depends on your probe and your gantry!

    Some of our testers got 0.25-0.35mm meshes after installation, but the magnet can be sanded to get better results.

  • Magnet is the issue

    The magnets that are used in 3D printer are imperfect. the thickness of the
    magnet with the adhesive layer may vary withing 0.4mm range (+-0.2mm).
    Fortunately, these magnets can be sanded. Use this kind of sponge blocks grit 60-80 to sand off any peaks on the mesh. With this trick our buyers could get their mesh from 0.44mm range down to 0.09mm.

  • Mount it right

    If you use the stock PRTouch bed probe then use the stock metal spacers to mount the bed. For other probes you may use springs with bed knobs which allow you to use the "Screw Tilt Adjust" for easy bed leveling.

Installation Instructions:

Follow the official Creality video with a few different steps below

220V Connection (stock SSR):

1. Connect 2 white wires to COM and 220B slots on SSR. Connect the blue grounding wire (grounding wire has a ring terminal).

2. Isolate with tape and DO NOT connect the 110v yellow wire.

3. Connect thermistor to the mainboard.

220V Connection (Aftermarket SSR):

1. Connect 1 white wire to OUTPUT 2 port on SSR. The other white wire to PSU N. Connect the blue grounding wire to PSU grounding port. Connect the stock wire that comes from PSU L to OUTPUT 1 port on SSR.Isolate with tape and DO NOT connect the 110v yellow wire.

3. There is a 4-wire cable that connects the board with stock SSR. Connect 2 middle wires from this cable to the SSR control side. Black with white lines is +, black is -.

4. Connect thermistor to the mainboard.

110V Connection (Stock SSR):

1. Connect 110v yellow wire (fork teminal) to COM slot, connect 2 white wires together to 110B slot on SSR. Connect the blue grounding wire (grounding wire has a ring terminal).

2. Connect thermistor to the mainboard.

110V Connection (Aftermarket SSR):

1. Connect 2 white wires together to OUTPUT 2 port on SSR. Connect the 110v yellow wire to PSU N. Connect the blue grounding wire to PSU grounding port. Connect the stock wire that comes from PSU L to OUTPUT 1 port on SSR.

2. There is a 4-wire cable that connects the board with stock SSR. Connect 2 middle wires from this cable to the SSR control side. Black with white lines is +, black is -.

3. Connect thermistor to the mainboard.

Rigid bed mounts

If you use stock bed probe (PRTouch) then use metal standoffs with M4 bolts.

Springs and knobs

If you use cartographer or other Eddy sensor bed probes, then you may use springs with M4 bolts with bed knobs for easy bed leveling using screw tilt adjust. You may buy the bed knobs or print the knobs from Printables.

Thermistor type

You need to make changes in printer.cfg file. Find heater_bed section and change senosr type to "sensor_type: NTC 100K MGB18-104F39050L32".

You may change the max_temp to 130 to be able to heat up the bed to higher temperatures.

Temperature Error

If you see negative temperature readings and printer throws temperature errors, that means that you did not change the thermistor type in the config file. See the previous step.

Also, some buyers had issues with the stock SSR. Our heater is more powerful than the stock heater (~1100W) and the stock SSR may not cope with it. If you see that bed heater power is 100% but the bed temperature is not changing, then you need to swap the stock SSR with an aftermarket one.

PID Calibration

The heater is more powerful than the stock heater. You need to run PID calibration in console by copy/pasting the command: “PID_CALIBRATE HEATER=heater_bed TARGET=70”. Then SAVE and restart

In this photo example it is the hotend temp graph. Bed temp graph can fluctuate in a bigger range than the hotend.
