REPEAT JOB — SAVED CALIBRATION
Repeat Job may automatically HOME XYZ as part of its proven recovery sequence. This HOME does not mean Steps 3–7 must be taught again while the physical setup remains unchanged.
For a changed/new setup: return to STEP 2 HOME XYZ → STEP 3 Surface Z → STEP 4 Bed/Paper Center before continuing.

  






  
LDM QUICK GUIDE
CALIBRATE ONCE · SAVE THE JOB · REPEAT WITH THE SAME PHYSICAL SETUP
The saved plotting reference belongs to the paper, tool and machine setup used when that job was prepared.

4REPEATUse LDM REPEAT JOB while calibration is unchanged. A machine-display standalone repeat must use a project containing its own HOME/reference startup.

  

  

    
✓ SAFE TO REUSE THE SAVED SETUP
Same paper/material thickness · same build plate and placement · same pen/blade · same tool extension · nothing physically shifted.

    
↻ RECALIBRATE FIRST
Paper/material changed · pen/blade replaced or moved · tool extension changed · plate/setup moved · Surface Z is uncertain.

  

  
SURFACE Z IS PHYSICAL.A saved Z value is only valid for the setup that created it. HOME establishes machine coordinates; it does not rediscover where the pen or blade touches a changed material.

  
REPEAT FROM THE A1 DISPLAY
Goal: a saved LDM project can later prepare itself and run without LDM. The standalone project startup must perform HOME/reference preparation before using its saved calibrated Surface Z.
G28 / HOME → INITIALIZE → SAVED REFERENCE → SAVED SURFACE Z → PLOT
Current 2EJ note: this tab documents the intended standalone workflow only; it does not yet inject G28 or change generated 3MF startup G-code. Until that startup is implemented, use LDM REPEAT JOB for the protected repeat sequence.

Calibration can be changed later. V1 uses relative Z lift.













Motion




Fixed plot-speed choices for predictable pen quality. A1 Normal / Sport / Ludicrous remains a separate printer-side multiplier.




Direct DRAW NOW only. Delay between MQTT G-code sends. Default 10 ms; enter any numeric value. Negative values are treated as 0 ms.




Straight SVG segments stay as one G1 move. Only curves are subdivided.



 ON



Recommended ON. When OFF, boundary/safety preflight is bypassed. SET BED/PLATE CENTER remains required as the drawing coordinate reference.






BED/PLATE CENTER: NOT SET — HOME XYZ → jog pen to physical BED/PLATE CENTER → SET BED/PLATE CENTER. SVG X0/Y0 = centered.
No job loaded.
DRAW LOG — load SVG, SET BED/PLATE CENTER, then START DRAW.


START DRAW NOW — LIVE SEND LOG




LIVE SEND LOG — waiting.








ARTWORK






 
FILES ON CANVAS0 items

 
List order = pen order. Tool stays at Z LIFT during each hold, then automatically continues. Finish changing the pen before the timer ends. Test with two small files first.
No files inserted yet.



 
 
 

 
Checked layers, or the active layer if none are checked. CENTER aligns both axes. Locked layers must be unlocked.



 

 








Transforms apply to checked layers as a group; with none checked, the active layer is used. Values use the active layer as reference; unchecked layers stay unchanged. Locked selections are protected. CLEAR clears the canvas.







  

  




0,0 = artwork centered on BED/PLATE CENTER. +X right, -X left, +Y up, -Y down.






You can also drag the loaded SVG directly in Preview.

TRACE


  
Choose a tracing tool. It opens in a full-screen workspace over LAN-DEV-MODE (LDM). Close it to return here, then import the exported SVG into the normal SVG workflow.

  
  
  
  
SquiggleCam: squiggle/plotter conversion. Pintr: single-line illustration. TRUE SCL V1+: identity-preserving, ordered single-centerline portrait workflow.

  

    NATIVE CENTERLINE TRACE
    
Rapid-Resizer-style local centerline extraction. Processing stays inside LAN-DEV-MODE (LDM).

FTE — FAST TRAJECTORY ENGINE (EXPERIMENT)

Workflow: Upload SVG → position/scale/rotate → BUILD / REFRESH FTE → SAVE GCODE TO SD → start from A1 LCD.
FTE.7: BUILD captures the same transformed artwork trajectory used by Preview; preview helper/border geometry is not collected.



V2(FTE).2 uses direct adaptive Bézier math to build a cached master path list from the current paper preview. Normal V2 drawing/SD output remains active and unchanged.

RECOVERY / CLEAN STATE

Use this only when an interrupted/bad plot leaves the A1 task context behind. CANCEL is a real A1 Cancel Print; it does not pretend the machine reached FINISH.










Not checked.

Recovery never starts a job. CANCEL sends one standard A1 print.stop only; status refresh is read-only/pushall. Delete is a separate SD action.


    

    
V18.64 captures the complete matching A1 ACK plus up to 40 raw post-command reports, final print report, state/error changes and the exact command sent. No automatic retry. A ✓ PROJECT READY package can be verified/started even when its raw .gcode companion is absent. V18.59 builds the companion from your genuine Bambu Studio LDM-RING package, uploads the .gcode.3mf FIRST, then raw .gcode on ONE FTPS connection, and verifies both before SAVE reports success. First test: known-good small square only.

Draw freely with mouse, stylus, or finger. Each press-and-drag gesture becomes one centerline stroke. Lift and draw again for disconnected parts. Guides mark the baseline, descenders and character spacing; drawing remains freehand without snapping. Font editing sends no machine motion.

 







Safety

V1.3 never generates heater/extruder commands. Laser mode is simulation-only and generates no laser-on/PWM commands. HOME and physically verify clearance before a real pen test. STOP lifts the pen and disables XYZ motors; it cannot erase already queued printer motion.
