BondTech CR-10S Extrusion Problem

Kaizer

Print Temp is the same as to when i calibrate Esteps. so i dont think is not hot enough.

Kaizer

M584 X0 Y1 Z2:3 E4 ; set drive mapping
M350 X16 Y16 Z16:16 E16 I1 ; configure microstepping with interpolation
M92 X100.00 Y100.00 Z400.00:400.00 E415.00 ; set steps per mm
M566 X900.00 Y900.00 Z24.00:24.00 E300.00 ; set maximum instantaneous speed changes (mm/min)
M203 X12000 Y12000 Z2000.00:2000.00 E6000.00 ; set maximum speeds (mm/min)
M201 X3000.00 Y3000.00 Z100.00:100.00: E10000.00 ; set accelerations (mm/s^2)
M906 X750 Y750 Z750:750 E650 I30 ; set motor currents (mA) and motor idle factor in per cent

as to why i have 2 Z settings. if i dont do it like this. my extruder wont even move.

@Kaizer I can see why you need to set two Z drivers. You have defined the extruder to use drive 4 in your M584. By default the first extruder (extruder 0) would be drive 3 and the second extruder (extruder 1) would be drive 4. Now in your tool definition you use drive 0. So if you don't define drive 3 as anything, then the firmware reverts to it's default and sets extruder 0 as using drive 3 so your extruder on drive 4 would become extruder 1. In that case, your tool, definition (M584) should use D1 not D0.

So you have several options. The simplest is to move the extruder to drive 3 and set the Z to only use drive 2. Or, if you really want to use drive 4, define the tool to use D1 not D0.

As for no filament coming out when you print, you probably just need to have a T0 command somewhere to select a tool. Either at the end of your config.g or in the slicer start code.

Do you your slicer set to relative extrusion and 1.75mm filament dia?

@Kaizer said in BondTech CR-10S Extrusion Problem:

M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1

also you are most likely printing at the wrong temperature. B4138 is the default and most likely wrong for your thermistors.

Kaizer

@deckingman Thanks. It makes a lot of sense now.
My Slicer start Gcode is only
G28 ; home all axes
G1 Z5 F5000 ; lift nozzle

should i add T0 as u said? if yes can u give me an example of the completed code?

Kaizer

@Veti i see, Im actually wondering about it too. but since i dont know much about it. i just leave it as is and do a temperature tower later on.

Im using the stock Bed thermistor for CR-10S and E3D V6 Tube Thermistor for my hotend. i dont know what their names are so idk what to set my thermistor as. if you know, mind sharing it? thanks.

deckingman

@Kaizer Literally, it's just "TO" on a new line (without the quotes). So:

G28 ; home all axes
G1 Z5 F5000 ; lift nozzle
T0

or put the T0 first if you need to heat the hot end before homing.

Kaizer

@deckingman Thanks alot. will give it a try now.

E3D V6

if its a genuine E3D the settings are: B4725 C7.060000e-8

Kaizer

@Veti Thanks, so its gonna be

M305 P1 T100000 B4725 C7.060000e-8 ; set thermistor + ADC parameters for heater 1

?

Veti

correct. the r parameter is not required as will be replaced by the correct one for your board.

Kaizer

@Veti what do u mean by r parameter? sorry i dont really understand programming language.

@Kaizer said in BondTech CR-10S Extrusion Problem:

M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0

R4700. That is optional and not required as its the default value.

Kaizer

@Veti i see, Thanks a lot.

Kaizer

@deckingman Thanks for the help. it works fine now.

deckingman

@Kaizer Glad you are sorted.
