Board

Press

Resolution mm — lower = more detail, slower

Trace Height mm — extrusion height

Min Hole Diameter mm — enlarged if smaller

Min Pad Size mm — pads enlarged to this minimum

Board 0.4mm base

Board Base Thickness mm — thicker = more rigid

Pad Enlarge Clearance mm — 0 to disable

Two-Sided Board — front + back boards side by side (half base each)

Two-Sided Gap mm — distance between front and back boards

Skip Unconnected Pads — remove copper around pads with no traces on that layer (useful for two-sided boards)

Ignore Pads — only generate traces

Edge Skirt — raised ring for edge copper tape

Skirt Width mm — width of the skirt ring

Skirt Gap mm — gap between board and skirt

Press 0.38mm clearance

Press Clearance mm — extra space for fit

Stencil Hole Diameter mm — through-hole marking size

Frame — border around press

Board Objects

Select one or more board copies to perforate

All selected boards must be copies of the same design. Perforating different boards in a single G-code is not supported — use separate G-code files instead.

Needle X Offset mm — from nozzle center

Needle Y Offset mm — from nozzle center

Spacing mm — between perforation holes

Outline Offset mm — from trace edges

Board Thickness mm — full STL height (base + traces)

Needle Depth mm — penetration below copper

Pierce Hole Centers Also perforate the center of all drill holes and vias

Safe Z Clearance mm — above copper surface

Travel Speed mm/min

Plunge Speed mm/min

Retract Speed mm/min

Determine the X/Y offset between your nozzle and needle

Needle Calibration

Download calibration plate

An 80×50mm plate with a raised cross-hair mark. The plate is asymmetric — the large area below the cross is where the needle mark will land. Print this on your 3D printer.

Plate Thickness mm — should match your board thickness

Upload sliced calibration plate

Import the STL into Bambu Studio, slice it, then upload the sliced .3mf file back here. This tells the app where the plate is positioned on the bed.

Calibration Plate Object

Run calibration G-code

Place the printed calibration plate on the bed and run this G-code. It will pause twice: once to attach the needle, once to mark the calibration point.

Measure the offset

After the G-code runs, measure the distance from the cross-hair center to the needle mark:

Needle mark to the right of the cross → positive X offset
Needle mark to the left of the cross → negative X offset
Needle mark below the cross (toward you) → positive Y offset

Enter these values in the Needle X/Y Offset fields above. You can also continue to Step 5 to verify.

Download verification plate

Optional — verify your measured offset

An 80×80mm plate with 16 through-holes in a grid. Print this, then run the verification G-code to check if the needle hits each hole.

Needle Offset X mm — from step 4

Needle Offset Y mm — from step 4

Upload sliced verification plate

Slice the verification plate STL in Bambu Studio and upload the .3mf here.

Verification Plate Object

Run verification G-code

Place the printed verification plate on the bed and run this G-code. It will pierce at each of the 16 hole positions using your offset.

Interpreting results:

All marks inside holes → offset is correct
All marks shifted the same direction → adjust your offset values
Marks shift by different amounts/directions → needle mounting is loose

PCB Board

Board with extruded traces and pads. Print this, apply copper tape, cut around the raised paths.

Press Tool

Negative space press with channels. Use to push copper tape firmly into the trace grooves.

Experimental

Outline Mode — thin walls only (press)

Outline Width mm — wall thickness around channels

Indented Traces — traces carved into board instead of extruded

Press Support Block — 3mm solid backing block to prevent board flexing when pressing

Holes-Only Calibration G-code — extra file with only THT hole punches, for testing needle offset

Colour-Code Perforation Dots — green: outline · blue: medial-axis · red: pair-fill · orange: hole centres
