How can I move E steppers?
January 11, 2023 01:03AM
How can I move the E axis steppers? I have like E0 to E3 steppers available.

But How can I move them with G code? (Pronterface)

G0 X50 moves the X axis.

But I don't know how to hove any of the E steppers.

And since they are mainly used for extruders, How can disable any cold filaments etc warning? (axis isn't used for filament)

Tried so far and not working:

G92 E0
G0 E10

Tried all "E" on X axis to make sure they work and all are working.

You need to switch the active extruder.

Send to command Tx where x is the number of the tool/extruder you want to be active. The first extruder is 0.

If you have PARKING_EXTRUDER enabled then you can add S1 to the command to stop the parking sequence.

Also extruders have protection, they will refuse to move if hotend is not hot.


use
M302 P1 ; disable cold extrusion checking

And yes each extruder is a tool

T0
G1 E20 ; move current extruder 20mm
T1
G1 E20
T2
G1 E20

Thank you. For a starter I had to enable the steppers in Configuration.h (doh!)

#define E0_DRIVER_TYPE TMC2209
#define E1_DRIVER_TYPE TMC2209
#define E2_DRIVER_TYPE TMC2209

(Strangely Y and Z where still set to A4988, still working)

T0 works fine. But with T1 and T2 I get Invalid extruder

My (Marlin 2.1.x) Configuration_adv.h has no #if EXTRUDERS > 1

#define EXTRUDERS 1


Up this number

Just defining the stepper driver is not enough as you can have mixing extrudes...

Thank you, I changed to #define EXTRUDERS 3 - plus (0 gives me a firmware error for the other two):

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 1
#define TEMP_SENSOR_2 1

At this point everything works! in combination with M302 P1.

Thanks again!

... for the extruders moving as you expect, you eventually have to switch between absolute and relative coordinates with "G90" and "G91" -- if absolute, then repeated "G0 E10" wont move after first occurance ...

Sorry to bring that up again, is M302 P1 same as M302 S0 ?

It should also go in the startup, right? (Machine is not for 3D filament printing)

#define STARTUP_COMMANDS "M302 P1"

And how to define more than one #define STARTUP_COMMANDS "***"?

Here's the docs for M302:
M302         ; report current cold extrusion state
M302 P0      ; enable cold extrusion checking
M302 P1      ; disable cold extrusion checking
M302 S0      ; always allow extrusion (disables checking)
M302 S170    ; only allow extrusion above 170
M302 S170 P1 ; set min extrude temp to 170 but leave disabled

To add commands add a \n and then the second command.
