Founded in 2014, Tenlog 3D was founded by professional software and hardware engineers with more than 10 years of R&D experience. Cura 15: Dual Extrusion Tutorial. Please manually feed the wire to the extruder (E0, E1) on both sides and push it to the red circle position shown below. Instead of attaching the project file to an e-mail, please visit with a browser and upload it here. I tried to reproduce this part of the issue on current master, but for me it kept replacing it correctly. G-code generator 2.0 (Cura 3.6) This G-code generator 2.0 will help you generate G-code for your printer. G1 X150 F5000 ; quick wipe. Cura 15.06. to your account.

Have a question about this project? If you want the extruder start g-code in the global start g-code, then you can put {machine_extruder_start_code, 0} in the global start g-code. By clicking “Sign up for GitHub”, you agree to our terms of service and But you need to retain the option to NOT execute the extruder start g-code as part of the global start g-code, because for instance: There are quite a lot of use cases for not wanting to have the extruder's start g-code executed at the beginning of a print. That is intended behaviour though. Do you have some profile/project to share where it does happen for you? The start gcode should be done only once. After reading many of the threads here and abroad, I put together a start GCode script for a two extruder printer. Gcode done twice, but nothing bad happens/printer not damaged. And insert the switch extruder just before the wait for heatup (M116): T1 start gcode Cura 15.04 (big changes post 15.04) single right ***> wrote: Sorry about trying to e-mail the zip file. Use this gcode to purge and wipe filiment before printing. At a minimum, the extruder and heated bed (if applicable) need to be set to proper temperatures and the tool head needs to be homed. Already on GitHub? {machine_extruder_start_code, initial_extruder_nr} puts in the wrong extruder, and it puts in the literal text: M109 T0 S{material_print_temperature} in stead of M109 T0 S190. This command behaves differently for DUAL_X_CARRIAGE vs. DUAL_NOZZLE_DUPLICATION_MODE. The TL-D3 Pro and TL-D3S independent Dual Extruder 3D Printers we developed are composed of independent dual-nozzles, filled in the market blank, and have obtained CNIPA invention patents. ***> wrote: We have had this discussion before, and it got changed to the way it is now. @Ghostkeeper the main flaw in reasoning here, is that it will always start printing with extruder 0. Also be sure to switch of brim and skirt as this always starts with extruder 0, even if extruder 0 is not even used. This is probably really obvious but anything in the start gets added to the output gcode before the slicer starts processing your model. This setting is not new. I have not had this issue on 4.0.0 though. On Fri, Sep 6, 2019 at 7:29 AM Ghostkeeper ***@***. I can confirm this on Cura 4.2.1.

I would not call this an issue, let alone a bug. Open both STL file, right click on model and select “Dual extrusion merge”. I've heard the report before but I can't find it right now among our open issues. Any factors left out are set to 0.0. I think that start.gcode should always be the first code in final gcode.

I am trying to set up the machine settings for my BigBox Dual. Register your Ultimaker for free 3D printer onboarding course. What seems incomplete about this story is, cura writes extrusions as "E#", which should also be moving the "T#" extruder motor. You needed to heat up the nozzle to execute the start g-code (e.g. So, if there's a bug here, I guess it's how Cura handles migrating of the start/end g-code from 3.6 to 4.x? I'm not that familiar with cura but for Prusa Slicer under the printer settings you have 4 areas to put custom gcode in, Start, End, before each layer and after each layer.

Does one of you have a project file that reproduces the problem? I started creating a new printer profile, and noticed the content was empty on the extruder settings, and I went back to my existing profile, and it duplicated the start and end g-code to the extruder's settings as well. Application version and it puts in the literal text: M109 T0 S{material_print_temperature} in stead of M109 T0 S190. If you want the extruder start g-code in the global start g-code, then you can put {machine_extruder_start_code, 0} in the global start g-code. You don't need to wipe the nozzle on a wiping brush at the beginning of the print. START.GCODE. I tried to reload a file but the start gcode still repeated twice. With the default setup of the machine if you followed the beginning of this guide, it will be at the front of the bed (X0, Y-130). By default cura heats up both extruders although only one extruder is used. Generate GCode for Dual-extrusion using latest Cura 1. This is based on a reference implementation by Pìa Taubert. ... dual extruder" to let GCODE be translated to X3G instructions that are suitable for the WANHAO Duplicator 4 that is a clone of "Replicator 1 - dual extruder". But when printing with only extruder 1, it puts in a start 0 and end 0 gcode between start_gcode and start of print. Cura by default does absolute extrusion, by there is a setting under the Special Modes print setup which turns on relative extrusion (you might need to un-hide that option in preferences). I upgraded to this from 3.6.0 (I believe), and it worked properly back then. (except when extruder 0 is disabled). Dual Extruder Start GCode heats both Extruders.

I think it should be possible to do {machine_extruder_start_code, initial_extruder_nr}, but I am not sure if the initial_extruder_nr is always calculated correctly.

The text was updated successfully, but these errors were encountered: How do you print? Problem: When I tried to print a new stl file for the first time on the new cura 4.2.1, the start gcode would begin, with the nozzle doing a prime line, but right when the line is finished, instead of beginning the part, the nozzle re-homes and does the start gcode again. Reproduction steps Simplified version. M115 U3.1.1 ; tell printer latest fw version This is wanted behavior. Platform The initial_extruder_nr part works. Does one of you have a project file that reproduces the problem? Anet A8 start end gcode. Removing the extruder's start/end g-code appears to have removed the duplication! You need to heat up the nozzle to the Printing Temperature for the global start g-code, but the Initial Printing Temperature after extruder switches. Delete all the information you have in "start.gcode"in Cura and copy this to "start.gcode" to start printing only on the second extruder: T1 G21 ;metric values G90 ;absolute positioning M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G1 Z15.0 F{travel_speed} ;move the platform down 15mm See But after the second time, the start gcode is not repeated and the part starts to print.

So it heats extruder 1 instead of 2. start gcode Slic3r single left. Use the single right gcode, but change the set nozzle temperature line (M104) to the following: M104 S[first_layer_temperature_0] T1 ; set nozzle temp, don't wait. Via USB, SD-Card, or OctoPrint? It's been there since at least 15.10 but there it seems to have been migrated from the 15.04 code base from when Daid worked on Cura: ec8ca8c The setting was introduced by Daid there but his version didn't have a version upgrade functionality so the migration wasn't a thing there. Sign in An example is: M190 S{material_bed_temperature} will produce something like: M190 S230. M107 ;turn off fan This occurred on my first gcode export from 4.2.1. If I load a small cube into a CR10S printer and save the g-code to a removable drive (USB stick in my case) then I get the following g-code: The start g-code is in there only once.

Also happens when extruder 0 is disabled, restarted Cura and now it does something else. — Attachments to e-mail replies to Github don't get published. The purpose of the start.gcode script is to prepare the 3D printer for producing the desired object. The first line will be the travel location for the filament swap.
