Delta Calculator

Actions

▼

Frame Geometry

▼

Bot Radius * ℹ Distance from the center of the build area to each tower. Larger radius increases build volume but requires more space.

* Marlin Config:
DELTA_SMOOTH_ROD_OFFSET

Bot Height ℹ Maximum height of the delta robot towers. This determines the maximum Z-axis travel and build volume height.

Rod Configuration

▼

Rod Spacing ℹ Distance between the rod attachment points. This affects the mechanical advantage and precision of the delta system.

Rod Radius ℹ Thickness of the diagonal rods. Thicker rods provide more rigidity but add weight to the moving parts.

Carriage & Arms

▼

Carriage Inset * ℹ Distance from the tower edge to the carriage center. Affects the range of motion and stability.

* Marlin Config:
DELTA_CARRIAGE_OFFSET

Carriage Height ℹ Vertical size of the carriage that moves up and down the towers.

Carriage Ball Joint Offset * ℹ Perpendicular offset of the ball joints from the carriage plane. Accounts for the physical offset when ball joints are not perfectly aligned with the carriage center.

* Affects Kinematics:
This offset changes the effective attachment points for diagonal rods.

Arm Radius ℹ Thickness of the diagonal arms connecting carriages to the effector.

Diagonal Rod Length * ℹ Length of the diagonal rods connecting the carriages to the effector. Longer rods provide more reach but may introduce flex.

* Marlin Config:
DELTA_DIAGONAL_ROD

Tower Center Offset ℹ Offset from the perfect center position for tower placement. Can help with mechanical clearances.

Effector Configuration

▼

Effector Type ℹ Choose the effector type that matches your 3D printer setup. Different effectors have varying mounting geometries and capabilities.

Effector Radius * ℹ Distance from the center of the effector to the rod attachment points. Larger radius provides more stability but reduces build volume.

* Marlin Config:
Influences DELTA_PRINTABLE_RADIUS calculation

Effector Spacing * ℹ Distance between the rod attachment points on the effector. This affects the mechanical advantage and precision of the delta system.

* Marlin Config:
DELTA_EFFECTOR_OFFSET

Build Plate Constraints

▼

Constraint Type ℹ Choose which physical limitation determines your build volume: effector geometry, bed size, or tower collision boundaries.

Effector Edge Effector Tip Horizontal Extrusions

Show Physical Bed ℹ Display the physical build plate boundaries in the 3D view. This is for visualization only and does not affect constraint calculations.

Physical Bed Radius ℹ Radius of your physical build plate. This is for visualization only and does not constrain the build volume calculations.
