Overview of Anycubic 4Max Pro

Sun, 06 Sep 2026 00:00:00 +0000

Introduction

The Anycubic 4Max Pro is an FDM 3D printer designed to print a variety of 1.75 mm plastic filaments that includes: PLA, PETG and ABS. It was a relatively cheap printer that was produced by Anycubic in the 2019-2020 timeframe. It was subsequently replaced by a new model, the Anycubic 4Max Pro 2 that aimed to improve handling of engineering filaments. However, these printers don’t seem to have been very popular and there is not that much information on them on the Internet.

Upgrade Anycubic 4Max Pro Firmware

Thu, 03 Sep 2026 00:00:00 +0000

Introduction

The Anycubic 4Max Pro uses Marlin as its firmware image. The printer ships with a very old version of Marlin (version 1.1.7) which does not support the capabilities introduced in the Marlin 2.x firmware. This guide describes how the firmware in the Anycubic 4Max Pro printer can be upgraded to a current version of Marlin.

This guide makes use of the Knutwurst version of Marlin which has been tuned for Anycubic printers such as the 4Max Pro. The Knutwurst Github also has a Wiki which contains a load of useful information about the printer and the firmware. The beginner’s guide is especially informative.

Tuning Anycubic 4Max Pro

Fri, 04 Sep 2026 00:00:00 +0000

Introduction

This guide describes various techniques for tuning the Anycubic 4Max Pro printer for best performance.

This guide assumes the printer is running a Marlin 2.x firmware provided by Knutwurst. Upgrading the printer to this firmware is described in this guide.

Bed Levelling

This section details how to level the bed of the Anycubic 4Max Pro to ensure the first layer of a print is laid down accurately.

In this process the height of the hotend nozzle above the bed will be measured by slipping a piece of paper between the nozzle and the bed. The nozzle Z-height will be adjusted until the paper is just lightly gripped between the nozzle and the bed, but can still be easily slid around. I measured the thickness of the paper and it was 0.1 mm. Thus, when the paper is lightly gripped, the Z-height of the nozzle above the bed should be just under 0.1mm.

Disassembly

Overview

The case of the printer consists of a number of large plastic panels attached to an inner metal frame by screws and clips. This section describes the removal of these panels to gain access to the innards of the printer.

Note

The panels must be removed in the order described here.

Removal of the Base

The electronics for the printer are housed in its base. These can be accessed by turning the printer upside down and removing its base. This involves:

Upgrade Anycubic 4Max Pro Hotend PTFE

Thu, 13 Aug 2026 00:00:00 +0000

Introduction

The Anycubic 4Max Pro printer’s hotend uses a piece of ordinary PTFE tubing between the nozzle and the extruder. At higher extruder temperatures this PTFE tubing can melt, causing clogs. To be able to work with higher temperature filaments this ordinary PTFE tubing needs to be replaced with something that supports higher temperatures. In this article it is replaced with a piece of Capricorn tubing.

Disassembly of the Hotend

This section describes how to remove the hotend from the printer.
