This guide applies to rotary printing with the eufyMake E1. It covers measurement methods for cylindrical cups, conical cups, and cups with handles, along with software settings, CMYK and white-ink process selection, printing procedures, quality control, and common troubleshooting steps.

Overview

The rotary tool operates with a driving wheel on the left and a driven wheel on the right.

• The driving wheel rotates the cup through a motor-driven shaft.

• The driven wheel provides support and assists with smooth rotation.

Supported Cup Types

• Cylinder

• Cone

• Cylinder with handle

Print height limit:

• Cylindrical Cup: 3D relief supports up to 1mm

• Conical cup: 3D relief supports up to 0.2mm

Non-Printable Area for Handled Cups

Areas near the cup handle cannot be printed. The software will mark this region on the canvas automatically.

PreconditionSoftware Platform and Usage

• Daily printing: App / PC

• Offline printing:

  • Connect the PC to the printer using AP mode

  • The editor supports Offline Mode (cloud-based resources such as AI, templates, and texture libraries are not available offline)

Print Settings

Select the print bed and material

• Print bed: Rotary

• Select material and quality

• The system will automatically match the required number of white ink (CMYK+W) layers based on material needs

Measurement Process (App/PC)

1.   Tap the Measurement icon

2.   Select the appropriate cup shape and choose Auto Measure

3.   Wait for the measurement process

• The App/PC retrieves the cup information from the printer

4.   Device actions (automatic):

• Fixture return-to-zero

• Measure top diameter

• Measure bottom diameter

• Measure height

• Level or lift if required

• Calculate and mark non-printable areas (for handled cups)

5.   The measurement results are returned to the App/PC and displayed on the canvas

• Geometric parameters

• Printable area

• Non-printable area visualized on the cup

• A prompt will appear: “Auto measurement is completed. The result has updated the canvas.”

Page Layout and Margins:

• Load your image onto the canvas.

• You may keep the original size or enable resize to canvas.

  After selecting the image, the following parameters appear on the right:

• Top Margin: Distance between the top of the image and the cup rim

• Bottom Margin: Distance between the bottom of the image and the base of the cup

  It is recommended to measure non-printable areas manually and set margins to avoid printing too close to the rim or base.

Ink and Process Selection:

• Flat or 3D Texture: Use Hard White Ink

• Foil Stamping: Must use Soft White Ink

• The software will determine the number of white ink layers required for the selected material

Preview:

• Preview the flattened rotary view to verify pattern position, top/bottom margins, and cup-handle clearance

• In 3D Texture mode, preview the height and surface texture before printing

Printing

• Start printing and monitor rotation stability and ink output

• If printing stops unexpectedly, record the on-screen status and follow the recovery procedure

Post-Processing (If Applicable)

• Gold/Silver Stamping:

  • Print with Soft White Ink

  • Apply heat with a handheld press

  • Peel the film after it has cooled completely

Common Issues and Solutions

Rotation Alignment Offset

• Reconfirm measurement values (height, diameters)

• Check contact between the cup and driving/driven wheels

• Verify top/bottom margins

Uneven Printing on Conical Cups

• Ensure leveling was completed

• Re-run automatic measurement

Contamination Near the Handle

• Confirm the non-printable area is marked correctly

• Increase margin appropriately

White Edges or Exposed White Ink

• Increase white-underbase choke as needed

• Verify correct material selection

Poor 3D Texture Performance

• Cylinders support ≤ 1 mm

• Conical cups support ≤ 0.2 mm

• Adjust texture thickness and smoothness and reprint

Incomplete or Misaligned Gold/Silver Stamping

• Ensure printing used Soft White Ink

• Confirm sufficient pressing time and pressure

• Peel after cooling
