Issue with extruder wont move

General Discussion

Basic Information:

Tevo Tornado:
Btt Skr 1.4 non turbo:
Host / SBC
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…I have all axis working but no matter what I try I can not get my extruder to move. I am very new to klipper so bear with me .
klippy tornado.log (62.7 KB)

did you make sure all the cables are properly plugged in? If they are, but it still doesnt work, try plugging the cable in to another motor like the x axis, then try moving the extruder. If that works, you may need to replace your extuder motor

3

I have checked all the cables I even swapped stepper drive .I even tried it again on the old mks board and it works perfect.

4

What kind of drivers are you using?
If TMCs, the configuration seems to be missing their definitions.

5

I am using TMC 2208 but I am not running them in uart so I didnt think I needed to ad a configuration . All the other steppers are working fine just the extruder .

6

Are you sure the stepper driver is set to standalone mode?

7

I have checked all the jumpers and they are all the same . I have swapped the drivers around and no change.

8

A different question: How do you try to check the movement of the extruder?

9

I heated the extruder up to 195 then sent G1 E50 F50 and nothing happened . I also tried to move it from the mainsail dashboard

Just going through things here:

  1. Checked your klippy.log and you’ve specified the correct pins for E0.
  2. If you’re not using the TMC2208 UART, how are you making sure that you have specified enough current for the drive? There’s the little pot on it but it’s a lot easier to hook up the UART line and specify (and change) the current in Klipper.
  3. Now, you haven’t shown any images of your board showing how you have set your jumpers.
  4. One thing I’m suspicious of is how you are connecting your stepper - have you confirmed that you are plugging in the connector to the “E0M” connector and not the “ZMB” (the Z axis driver has two parallel stepper motor connectors).

My recommendations:

  1. Make sure you’re plugging your Extruder Stepper Motor into the “E0M” socket.
  2. Wire up the TMC2208 UART connections for the drivers and make the necessary changes to your printer.cfg. Things are much easier to work with this way and there’s no confusion as to what mode the stepper driver is in.
  3. Share images of how you have set the jumpers for the various drivers.

as bad as I hate to admit it you got it right . I had the extruder plugged into the second z port on the board . Thank all of you for trying to help me out .
