Working on the hotend, dialing in the Stealthburner, this has taken several disassembles of the unit.

m564 S0 H0 allow steppers to move without homing
extruder run G1 E100 F60
M563 P0 D0 extruder

m84 release motors

M302 P1 to allow cold extrusion.

M84 disable steppers
M84 turns off idle hold and this can also be applied to specific motors e.g. M84 E0:1:2

This unit is printing, I've had issues with the hotend, having the 1lc canbus board on the head assembly just completes the way to big and bulky assembly specification. The expensive print head cloggs and i'm getting a disassembly technique established. It's big fan assembly and the fact the hotend fan runs off the duet control and it's default is off. Have the heater on without the fan and your getting some disassembly experience. I'm actually considering the first gen print head. I ordered a parts assembly that are injection molded.

How are the motors numbered on the voron 2.4, which driver to which motor using duet 3 6hc

On a Voron 2.4 with a Duet 3 6HC, the motors are typically mapped as follows. Since the 6HC has six integrated stepper drivers (Driver 0–5), here's the recommended motor-to-driver mapping, assuming you're using the Stealthburner or Afterburner toolhead with coreXY kinematics:
🔧 Motor Numbering (Voron 2.4) and Duet 3 6HC Driver Mapping
Motor Function Voron Name Duet 3 6HC Driver Notes
X Motor X Driver 0 Part of CoreXY system
Y Motor Y Driver 1 Part of CoreXY system
Z Motor (Front Left) Z1 Driver 2
Z Motor (Front Right) Z2 Driver 3
Z Motor (Rear Center) Z3 Driver 4
Extruder Motor E0 Driver 5 Orbiter, LGX, etc.
🔌 Duet Wiring Notes:

The order of Z motors doesn’t matter for physical connection, but you must define them properly in firmware for bed leveling and Z tilt correction.

You may optionally add a toolboard or expansion board for a second extruder or other devices.

🧱 RepRapFirmware config.g Snippet:

; Motor remapping for CoreXY
M584 X0 Y1 Z2:3:4 E5 ; 

Driver 0=X, 1=Y, 2/3/4=Z, 5=Extruder
M671 X-10:310:150 Y10:10:345 S10 ; Z screw coordinates for bed leveling (adjust as needed)

M584 maps the drivers.

M671 defines physical Z lead screw locations for G32 Z-tilt correction.

Let me know if you're using CAN toolboards, expansion boards (like 3HC), or independent Z motors with sensorless homing—those details can change your configuration.
You said:

ok im going to have to deep dive this, mine is wired different but it works and was working great until the right rear z motor error-ed for phase short. the motor would just quit. so i replaced the motor and it still happened on occasion, so i replaced the duet3 6hc and it's happening again. this has a 1lc tool board if that makes any differance. it has to have a config error or software issue. I will identify the driver numbers and their location on the duet 6hc and verify which driver is driving which motor then provide this with the config file to see if i can sort this out

Chat said:

That’s the right approach — if the problem persists across two different 6HC boards and a new motor, it’s almost certainly a wiring issue, driver misassignment, or software/configuration bug.

Once you:

Identify each motor’s physical connection and its corresponding driver (0–5),

Provide your current config.g (and optionally config-override.g if it's in use),

…I’ll walk through the setup and pinpoint any mismatches or conditions that could be triggering false shorts or misbehavior.

Also helpful: are you using shielded motor cables, and are the wires crimped cleanly with no exposed strands near connectors? Duet boards are very sensitive to noise and intermittent connections.
You said:
orignally i thought it was a cable issue and it appeared to be , i installed a new motor that had wires coming out of the motor, steppersonline , they are 4 single wires and i dont believe shielding is present

Chat said:

Thanks — that detail matters a lot.

Unshielded stepper wires (especially long ones or wires running near other high-current lines) can definitely cause:

false phase errors

driver overheating

intermittent shutdowns, especially during fast moves or Z-lift

Here’s what’s likely happening:

Duet 3's TMC5160 drivers constantly monitor coil current balance.

If signal noise or poor continuity causes an imbalance between A and B coils, it throws a “phase short” error even when there's no real short.

Having 4 unshielded individual wires (instead of a twisted pair or proper shielded cable) amplifies this effect — especially on the Z axis where all motors share motion and are often driven at lower current.

✅ Recommended Fixes (Immediate and Long-Term)
Short Term:

Reduce Z motor current slightly (e.g., from 1000mA to 800mA) in config.g using:

M906 Z800

That can reduce stress on detection circuitry.

Tighten acceleration & jerk on Z:

M566 Z4 ; Jerk in mm/min (default often too high)
M203 Z300 ; Max speed
M201 Z20 ; Acceleration

Try a different driver port temporarily (e.g., move that motor to Driver 5 or external board) to rule out driver-specific faults.

Long Term:

✅ Replace with shielded, twisted pair cable (24 AWG or thicker), or buy stepper wire specifically made for 3D printers.

✅ Use crimped JST VH or Molex connectors — don’t just twist and tape. Duet boards are very unforgiving about clean power signal integrity.

Once you ID the driver/motor assignment and share config.g, I’ll help cross-reference any logical mismatches or electrical stressors in the current setup.

time to re calibrate our sensors. i was looking at the duet upside down. human mistake

ChatGPT said:

Perfect — thanks for the reset. Let’s wipe the slate clean and rebuild from your correct physical wiring.
✅ Confirmed Driver-to-Motor Mapping (with Duet 6HC held correctly)
Driver Connected Motor Function
Driver 0 Z0 Front Left Z
Driver 1 Z1 Rear Left Z
Driver 2 Z2 Rear Right Z ✅ ← (this is your problem motor)
Driver 3 Z3 Front Right Z
Driver 4 B motor X axis (CoreXY)
Driver 5 A motor Y axis (CoreXY)
🧠 Now Your M584 Should Be:

M584 X4 Y5 Z0:1:2:3 E121.0

Which is exactly what you're currently using. ✅

So:

Physical wiring = ✅ correct

Driver assignments in config = ✅ correct

This confirms: your repeated Z2 (rear right) error is not a config mismatch, it's a hardware-layer issue (likely EMI or contact failure).
✅ Action Plan from Here

Since config and driver mapping are valid, here’s what will actually fix it:
🧪 1. Run M122 after error

Look at the last section:

Driver 2: ...

It will say:

short-to-ground

open-load

or show driver status flags (hiccups, stst, drverr, etc.)

🧰 2. Fix Physical Layer

Twist wires tightly if unshielded, or replace with shielded 4-wire cable (24 AWG or better)

Make sure all 4 crimps are solid and inserted fully into connectors (Duet is very picky about connector integrity)

Check that wires don’t run directly beside heater/bed power or motor cables without spacing

🔧 3. (Optional) Lower Motor Current Temporarily

To reduce false trips during tests:

M906 Z800

🛠️ 4. Reduce Z Axis Jerk and Acceleration

M566 Z100
M201 Z100

Let me know if you'd like a config snippet with lower Z acceleration/current for testing — or if you want help reading the M122 fault output. You're in the home stretch now.

here is my cura settings, i'm using .4 nozzle
ChatGPT said:

Great — thanks for sharing your Cura machine settings. This helps verify whether your slicer is aligned with your RepRapFirmware Voron 2.4 setup.

Here’s a quick audit based on what I see:
✅ Cura Machine Settings Review
🔧 Printer Dimensions
Setting Value Comment
X, Y, Z 350 mm ✅ Matches Voron 2.4 350 spec
Build plate Rectangular ✅
Heated bed ✅ Enabled ✅
Origin at center ❌ Off ✅ — Voron does not use center origin
G-code flavor RepRap ✅ Correct for RRF / Duet
🧠 Toolhead Offsets (Printhead Settings)
Axis Min Max Meaning
X -35 35 Head moves 35mm left of nozzle center, 35mm right — width = 70mm
Y -50 65 Head moves 50mm back, 65mm forward — depth = 115mm
Gantry Height 30 mm ✅ Typical Voron value

These offsets are important for proper purge line placement and nozzle clearance during skirt/brim.

So far, this all looks good.
🔎 Two Tweaks You Might Consider
1. 🔁 Start G-code: Add homing and purge line

Right now, your start G-code is minimal. Here's a more complete, Voron-friendly start sequence for Cura:

G90 ; Absolute positioning
M83 ; Relative extrusion
G28 ; Home all axes
G32 ; Bed level / quad gantry align (if configured)
G92 E0 ; Reset extruder
G1 Z0.3 F6000 ; Lift nozzle
G1 X5 Y5 F10000 ; Move to corner
G1 Z0.2 F300 ; Lower to purge height
G1 X100 E10 F1000 ; Purge line
G92 E0 ; Reset extruder again

You can append this after Cura's generated temperature lines.
2. 🧪 Cura Z Offset

If you're using a Z offset in your firmware (G31 Z...), you don’t need to adjust Z height in Cura.

Leave “Build Plate Adhesion Z Offset” at 0 in Cura

Let firmware handle Z probing and offsets

✅ You're Good To Slice

You’re on track — with the .4mm nozzle, RepRap flavor, and correct bed size, you're ready to start printing (once we finish fixing that Z2 motor issue).

Let me know if you'd like optimized Cura start + end G-code blocks tailored for your Duet 3 + Voron setup.

ChatGPT said:

Perfect — since you're using a Voron 2.4 350 with Duet 3 + RepRapFirmware, and have the ChaoticLab CNC Tap V2, here are fully optimized Cura Start and End G-code blocks tailored for your setup.
🧩 Key Assumptions:

You're using G32 for quad gantry leveling with TAP

You're using G29 optionally for mesh compensation

Your TAP is already configured in config.g with M558, G31, etc.

Your Duet is set to handle all Z offsets, so Cura doesn't need to

G1 X0 Y350 F6000 ; Park head at back-left
M106 S0 ; Fan off
M104 S0 ; Hotend off
M140 S0 ; Bed off

💡 Optional Notes:

If you don’t want to probe mesh every time, just use G32 for fast quad gantry alignment.

If you're using input shaping or pressure advance (M593, M572), you can handle those in config.g, not Cura.

You can add M564 H0 at the start if you want to allow movement before homing (usually not needed).
