Settings and Notes Related to the Anycubic 4Max Pro 3D Printer.

The heated bed of this printer tends to get warped and it becomes imposible to manually level the bed. The alternative is to add Mesh Leveling capabilities to this printer to make it usable.

The printer uses a trigorilla board v1.0 but please double check by opening up the base of the printer and check the mainboard (see https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/wiki/Beginner's-Guide-(English)#3-identification-of-the-mainboard )

There is also a daughter board connected which has the pins for the end stops.

WARNING: USE AT YOUR OWN RISK! Please make sure to do your own configuration and conduct your own research before flashing your printers firmware, installing a BLTouch or configuring the BLtouch for the printer. I am not responsible for any potential risks, loss or damage to your health, your 3d printer, your house or those around you should you use the Anycubic 4Max Pro or follow or use any of the settings, files or information provided on this github repository. USE AT YOUR OWN RISK!

Try to acquire a genuine BLTouch device as there are reports of clones generally failing or having quality issues. Make sure to also get the 1.5m extension wire with the dupont connectors.

The trigorilla mainboard on the Anycubic 4Max Pro has the servo control pins already soldered on "+ - Power" "- - GND" "S - Signal"

But the BLTouch dupont connector needs to be reconfigured (see https://www.antclabs.com/wiring ) to swap the power and ground. Original BLTouch Wiring

Find a suitable BLtouch mount or experiment with one of the following:

Make sure to calibrate the location of the BLTouch Probe in relation to your nozzle.

Remember the X,Y,Z are coordinates oriented when you're facing the front of the printer (ie. the door on the front of the 4Max Pro). Y axis is the movement towards and away from you. So +Y is moving the printer head away from you, -Y is moving the printer head towards you. X axis is the movement left and right of you. So +X is moving the printer head to the right, -X is moving the printer to the left. Z axis is the movement up and down. So +Z is moving the pritner head up away from the printer bed, -Z is moving the printer down towards the printer bed.

Knutwurst's i3 MEGA M/S/P/X/Chiron/4MP2 Hybrid Firmware (based on Marlin 2.1.x) https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/releases

Make sure to compile your own version using the Arduino IDE and configure the X,Y,Z offsets! Make sure to follow the post firmware installation calibration steps.

Lay the printer flat so that the bottom cover is exposed. To remove the base plate remove the four hex machine screws (M3x12) and also remove the padded covers and remove additional 4 machine hex screws (M4x8).

Stand the printer back up (you can use the cover to protect the main board). Remove the 8 screws on the back panel and remove the back panel to get run the extension cable through the existing cable management. You may want to add your own zip ties to anchor the new wires.

Lay the printer flat again (ie. front door laying flat).

If "Origin at Center" is checked when slicing the printer seems to print off the printbed and in the lower left quadrant. Recommendation is to keep this setting unchecked.

Example:

Heat up the bed

G28

G90

G1 Z10

G1 X40 Y40 F4000

M280 P0 S10

G91

Slowly lower the nozzle with G1 Z-1 or G1 Z-0.1 or G1 Z-0.02 until the sensor is triggered. NOT FURTHER!

If the sensor has triggered and flashes: M280 P0 S160

M114 = Current position of the nozzle -> note! (e.g. Recv: X:40.00 Y:40.00 Z:1.30 E:0.00 Count X:3200 Y:3200 Z:520)

G90

G1 X38 Y15 F4000 (values ​​from point 10 + offset of the sensor, i.e. X=40+(-2) and Y=40+(-25))

G91

Place a sheet of paper under the nozzle

Slowly lower the nozzle with G1 Z-1 or G1 Z-0.1 or G1 Z-0.02 until the paper is difficult to move.

M114 = Current position of the nozzle -> note! (e.g. Recv: X:38.00 Y:15.00 Z:0.70 E:0.00 Count X:3200 Y:3200 Z:520)

Subtract the Z value from point 16 from that from point 10 -> 1.30 - 0.7 = 0.6 mm -> This is our Z offset.

M851 Z-0.6 (be aware of the negative sign!)

M500

Carry out Autoleveling again via the display. Finished.
