Thanks here you go `## Hint: [0] means array of values ([0], [1], [2]...)

Temperature handling

use_id: should M104 commands have tool id. M104 S210 or M104 S210 T1. Firmware dependent

tool.temperature.use_id: True

What command to use for controlling nozzle temperature. M104 and G10 supported

tool.temperature.command: M104

Nozzle diameter. Used with slicers (Cura) that do not provide settings in gcode files

Overridden for S3D, Slic3r and KISS

tool.nozzle.diameter: 0.4

Z-hop when moving to and from the tower. Used with slicers (Cura) that do not provide settings in gcode files.

Overridden for S3D, Slic3r and KISS

tool.tower.zhop: 0.5

Machine properties. Used with slicers (Cura) that do not provide settings in gcode files.

0 is cartesian, 1 delta

machine.type: 0 machine.x.length: 220 machine.y.length: 220 machine.z.travel.speed: 1000 machine.xy.travel.speed: 1000 machine.origin.offset_x: 0 machine.origin.offset_y: 0 machine.default.speed: 1000

Extruder motor current values. Adjusts motor current using M907. Values are

for load/unload and for normal operation.

load = motor current for load/unload

run = motor current for normal operation

These can be set to 0 if not applicable

motor.current.load: 0 motor.current.run: 0

These prepurge steps are executed before the actual prepurge. They seem to help with tip formation on some cases

Disabled by default

prepurge.initial.retract: 20

prepurge.initial.retract.speed: 350

prepurge.initial.pause: 2500

Prepurge means the fast purge movements that purge old material before tool change

- temperature = change temperature of the nozzle this amount before doing the prepurge. Negative value lowers the temperature

- length = length of one sweep

- extrusion.length = how much material to extrude per sweep

- speed = how fast to move in one sweep

- count = how many sweeps

- gap = distance to next sweep line

prepurge.temperature.change: 0 prepurge.sweep.length: 20 prepurge.sweep.extrusion.length: 4.5 prepurge.sweep.speed: 1000 prepurge.sweep.count: 5 prepurge.sweep.gap: 1 prepurge.sweep.gap.speed: 800

Prime extruders

Change next line to True to enable

prerun.prime: true prerun.prime.length: 49 prerun.prime.extrusion.length: 1.8 prerun.prime.gap: 0.48 prerun.prime.speed: 1000 prerun.prime.xstart: 5.0 prerun.prime.ystart: -3.0 prerun.prime.purge.count: 6

Rapid retract means pulling the filament out of the nozzle.

Various stages can be defined.

- initial retract happens right after prepurge is done

length and speed are self explanatory

wipe = do wipe movements during retracts to reduce oozing

pause = how long to let filament cool in throat (ms)

long retract = pulling filament fully out of way

rapid.retract.initial[0].length: 10 rapid.retract.initial[0].speed: 800 rapid.retract.wipe: False rapid.retract.pause: 900 rapid.retract.long[0].length: 12 rapid.retract.long[0].speed: 800

Various filament cooling movements after major retract. Uncomment to enable. Make sure that there are even amount

of cooling movements and the total length is 0

Serves as a wipe

rapid.retract.cool[0].length: 3

rapid.retract.cool[0].speed: 1600

rapid.retract.cool[1].length: -5

rapid.retract.cool[1].speed: 1600

rapid.retract.cool[2].length: 5

rapid.retract.cool[2].speed: 2000

rapid.retract.cool[3].length: -5

rapid.retract.cool[3].speed: 2400

rapid.retract.cool[4].length: 5

rapid.retract.cool[4].speed: 2400

rapid.retract.cool[5].length: -3

rapid.retract.cool[5].speed: 2400

After tool change, feed new filament

Use one or more stages (array). Feeding is recommended to do in different speeds:

- start relatively slow

- ramp up the speed for the main length of the feed

- slow down for the last bit for smoother insert

feed[0].length: 10 feed[0].speed: 400 feed[1].length: 25 feed[1].speed: 600 feed[2].length: 27 feed[2].speed: 800

Do X movement during feeding to prevent blobs

Change next line to True to enable

feed.trail: True

prime trail is the first extrusion after filament is almost fully fed to the nozzle.

Might be useful for clearing old filament if extruding bit more than normally

prime.trail.extrusion.length: 5 prime.trail.speed: 900

Tower coasting length. Use to even out the extrusion after tower if there's over-extrusion seen.

post.tower.coast: 0.2`

Change prepurge.sweep.length: 20 to 50 or something

Excellent! Thanks man great stuff appreciate all the work!
