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.
¶ Precondition
¶ Software 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)
¶ Tap the Measurement icon
¶ Select the appropriate cup shape and choose Auto Measure
¶ Wait for the measurement process
- The App/PC retrieves the cup information from the printer
¶ 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)
¶ 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
