X-In/1-Out Non-Mixing Extruder Config

Maturity · November 18, 2022, 4:18am

I am not at the computer in the printer room right now but in Cura there is a Printer Settings (or some such) plugin that you can add. With it you can set something like shared heater. Also in multi-extruder cases make sure that the extruder idle temp is the extrusion temp. And I use a gcode find&replace macro to remove M104 T[0-7] S0 but I think that may have been fixed in the current revisions of Cura.

In general I also filter out the Tn Gcodes and use the slicer to insert calls to TOOL_START=Tn and TOOL_END=Tn and use those macros to switch extruders and stuff. Makes it more controllable in Cura, IMHO anyway

Hello. There is a printer with 5 extruder motors. I made the settings you gave, but I am getting the following error.

$ ACTIVATE_EXTRUDER EXTRUDER=extruder_stepper extruder3
!! Malformed command ‘ACTIVATE_EXTRUDER EXTRUDER=extruder_stepper extruder3’

am getting this error in extruders that I define as extruder_stepper. There are 2 hotends in my printer. I tried many ways and searched but couldn’t find it. Can you help me?

Try
ACTIVATE_EXTRUDER EXTRUDER="extruder_stepper extruder3"

Sineos · December 4, 2022, 10:31am

Key are the " around extruder_stepper extruder3

Blockquote Next, remap the built-in ACTIVATE_EXTRUDER gcode macro so it can be used in your slicer:

My printer has 2 hotends. One is 2 in 1 out and the other is 3 in 1 out. How should I edit this code? Extruder as follows;

Extruder
Extruder1
belted_extruder2
belted_extruder3
belted_extruder4

I tried a few times but couldn’t find a solution. I edited the motion macro code as follows and it worked, but I couldn’t figure out ACTIVATE_EXTRUDER.

@craagle Did you get your setup working yet?

From the looks of things, you have two “motion system”; Extruder and Extruder1. and you also have three additional belted_extruders.

I didn’t notice, but what belted_extruders are hooked up to which Extruder?

craagle · December 10, 2022, 11:27am

Hi @jjarosz

Thank you for your interest. I set up Extruder and belted_extruder2 as the first group, and Extruder1 as belted_extruder 3 and 4 as the second group. Extruder and belted_extruder2 are working now, but I haven’t tried the other group yet.

Hi @jjarosz

I tried the example you gave and I did not get positive results. Since I couldn’t find a solution, I changed my device to a single hotend. At the moment, I am adhering to your solution plan.

I couldn’t use dual hotend with your solution. We need to work for this. Thank you very much for your support.

SphaeroX · February 5, 2023, 4:27pm

is there a way to run both extruders at the same time so that material is mixed? like the Marlin m165 gcode, run multiple extruders in relation to each other.

jjarosz · February 6, 2023, 3:01am

@SphaeroX it looks like the Dev team may have built the ground work to support mixing extruders, you would have to put it together between macros and slicer config, much like I did with this document.

Check out these two articles:

github.com/Klipper3d/klipper

M163 mixing filaments : support for rxtruder with multiple filament : for clay printing

nuhwandah

I'm in the process of migrating from Marlin, and would like to use Klipper on my… RepRap Clay printer that uses g-code M163 to divide extrusion between a ram and nozzle. I'm not too great with the tech side (it took me months to get my clay printer going in Marlin and I'd like to try using Kilpper.) I was wondering if anyone would be interested in the same thing ?

This PR adds a new `SET_EXTRUDER_ROTATION_DISTANCE` command. It supports specif…ying a "negative rotation distance" which will have the effect of reversing the extruder stepper direction. This may be useful for printers with a single extruder motor that can switch between two hotends via a servo. I do not have a good way to test this PR. Feedback would be appreciated. This PR is a continuation of PR #5143. This PR also deprecates the `shared_heater` config option, deprecates the `SYNC_STEPPER_TO_EXTRUDER` command, and deprecates the `SET_EXTRUDER_STEP_DISTANCE` command. There are new replacements for all of these features. This PR was built on top of PR #5209. @drumclock , @tircown - FYI. -Kevin

Basically start with what was built in 950 with stepper_extruder module and figure out a way to integrate 5210 SET_EXTRUDER_ROTATION_DISTANCE.

SphaeroX · February 6, 2023, 3:19pm

So if I have understood correctly, then I can determine the rotation distance via the GCode. For example, if I had a total of 30, I could say extruder 1: 15 and extruder 2: 15.

So far so good, but how do I get the two to rotate at the same time?

jjarosz · February 6, 2023, 3:31pm

You would have to activate two extruder_stepper objects at the same time.

The document I created only has one active at a time.

SphaeroX · February 6, 2023, 3:51pm

Then I will probably use Marlin, although I actually always use Klipper. With Marlin you make a GCode and you’re done, stress-free.

Xcaldoug · April 13, 2023, 10:06pm

Hello! I’ve used this config on my Ender 3 Pro, but am encountering an unknown problem where both extruders move at once.
Here is a link to a reddit post I’ve made on the issue

Thank you in advance!

jjarosz · April 14, 2023, 8:28pm

@Xcaldoug I looked at your printer.cfg you posted and there does not seem to to be any config issues. I also checked out your klippy.log file and that looks as if you have more issues that need attention than trying to get the extruder steppers working.

Also, are you using the Creality Sonic Pad by chance? If so, that could be the root cause of your issues. Creality is not using the stock Klipper code and/or the Klipper version might be lower than what is needed for [extruder_stepper] to even work.

Check the top of my post to see the earliest version of Klipper that I have this working under.

DrumClock · April 15, 2023, 8:35am

Hi, my configuration including macros is here:

MULTI HOTEND

If a hotend of type 2 IN 1 OUT (or xx IN 1 OUT) is used, the filament is automatically replaced outside the printing area.

By default, it is set to the endstop position + 20 mmm. Also tested on IDEX.

The variable for the currently installed filament is saved on the SD card, so that the last configuration is set when the printer is turned on.

The macro is here: MULTI_HOTEND.cfg

This macro is automatically called from the : SETTINGS_TOOL macro

For printers on the IDEX system from the macro: ACTIVATE_CARRIAGE

The macros listed on my Github are universal for configurations
printers for 2 to 4 extruders including dual carriage (IDEX)

This is an example of printer HW configuration for IDEX and 2 IN/1 OUT
