BUT! If i send

Hi !! And sorry for the late response !!
as you can see in the picture, If first send G91 and then G1 X100 F100 or G1 Y100 F100 to my X or Y axis, they move 100mm in 60 Sec
but if I send G1 E100 F100 to my printer, it Extrude 100mm filament, but in 27sec ?! how do I calibrate the speed of E ?
The length is right, it extrude exact 100mm, but the speed of the extruder is much to fast !!!
And! if I send M221 S50 To get 50% Speed, my X and Y Axis Moves 100mm in 120 sec = OK
but if I the send G1 E100 F100, it extrudes in the same rocket speed , but only 50mm ?
Sys Info: Geeetech i3 Pro c
Firmware Marlin 1.1.9

Hello.
You have prepared a beautiful description of the problem.
I wonder if the motors are connected to the correct sockets.
If you connect the extruder motors to the sockets where the X and Y axis motors are now connected, you will get the opposite effect.
It is worth to check it.
Edit:
A friend of mine says you should publish photos with speed settings
(a feed speed calibration as well as feed rate).
You will find them in the printer menu.

Hi !
I must have connected my cable right, or it would not work at all ?! and my X and Y are working fine ..
My speed settings in my printer menu is 100% But, the F command:
Sets the speed ?
Edit: Iv just tested the second Nozzle, and that too feeds to fast..

It may not set the speed, but it moves at a given speed. A matter of naming.
Valid until the parameter F is changed. So that you do not have to write the same every time.
Maybe we didn't understand each other a little bit.
So I have a request. Actually, two.
- 1. tell me what version of the controller's board you have.
- 2. take a photo of the controller with the cables connected to the engines and sign which one is connected to which engine.

Its Wooooorking
configuration.h ... must i say more..... LoL
Code: Select all
/**
* Default Axis Steps Per Unit (steps/mm)
* Override with M92
* X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
*/
// Mine #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 2560, 95, 95 }
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80.3, 80.8, 400, 93 } //Orig { 80, 80, 4000, 500 } 93*2 = DRV8825 1/32 Stepps
/**
* Default Max Feed Rate (mm/s)
* Override with M203
* X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
*/
// Mine #define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
#define DEFAULT_MAX_FEEDRATE { 400, 400, 400, 45 } //Orig { 300, 300, 5, 25 } //1.0.3 { 300, 300,20, 25 }
/**
* Default Max Acceleration (change/s) change = mm/s
* (Maximum start speed for accelerated moves)
* Override with M201
* X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
*/
// Mine#define DEFAULT_MAX_ACCELERATION { 3000, 3000, 100, 10000 }
#define DEFAULT_MAX_ACCELERATION { 5000, 5000, 50, 5000 } //1.0.3 { 3000, 3000, 100, 10000 }
Iv upgraded my firmware for some weeks ago, and since the firmware was for my printer, i did not save my configuration.h file...
why would I ? it was for my printer and controller board..
(Big mistake !!)
Thanks !!!!
