Generate GCode for Dual-extrusion using latest Cura 1. Startups, apply for the Forward AM Innovation Award! Does one of you have a project file that reproduces the problem? For Cura you can add additional wait commands to the start gcode if you want, but note that the format is slightly different (See here) : M190 S {print_bed_temperature} ; Set bed temp. @fieldOfView that would work, but... just tested it. Reply to this email directly, view it on GitHub Instead of attaching the project file to an e-mail, please visit github.com with a browser and upload it here. @Ghostkeeper the main flaw in reasoning here, is that it will always start printing with extruder 0. 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. I think that start.gcode should always be the first code in final gcode. The problem here is that the extruder start g-code is executed at the beginning. G1 X150 F5000 ; quick wipe. M109 S {print_temperature} ; Wait for all used extruders to reach temperature. 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. 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: 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. Any factors left out are set to 0.0. 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. M107 ;turn off fan G28 X0 Y0 Z0 ;home X, Y and Z axis end-stops G29 ;initiate z-probing G1 X0 Y0 Z.10 ;move to corner of bed G92 E0 ;zero the extruded length G1 F200 E3 ;extrude 3mm of feed stock G92 E0 ;zero the extruded length. Windows 10, Printer Hello, My start g-code when I do use use Cura 3.2 is as follows. Cura 15: Dual Extrusion Tutorial. Do you have some profile/project to share where it does happen for you? 1ste start gcode then start extruder gcode, as it is the start of the extruder. Ah, yes, the extruder start and end gcode snippets would have to be processed before the start gcode snippet for this to work. Already on GitHub? Figure 1: GCode Tab. I created a new project, and exported the gcode, and here is the respective ***> wrote: I upgraded to this from 3.6.0 (I believe), and it worked properly back then. Actual results Have a question about this project? Reproduction steps Import config file cura.ini 3. Also happens when extruder 0 is disabled, restarted Cura and now it does something else. By default cura heats up both extruders although only one extruder is used. But GPX doesn't start extruding T0 with the sequence T1 M104 T0 S175 G1 F1500 E-0.6 ; retract So something's still missing from the explanation. (1) Start GCode. What happens if you want to start printing with extruder 1 or 5? I'm unable to reproduce this issue so far. privacy statement. The first line will be the travel location for the filament swap. Reply to this email directly, view it on GitHub 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. You are receiving this because you commented. Removing the extruder's start/end g-code appears to have removed the duplication! 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). — 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 WANHAO Duplicatro 4 + GPX + Cura => start/stop GCODE I am in need directions please Showing 1-1 of 1 messages. Please do not change it back. So it heats extruder 1 instead of 2. ... 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". So, yes, there is something wonky there. SD card. New here? I've heard the report before but I can't find it right now among our open issues. What seems incomplete about this story is, cura writes extrusions as "E#", which should also be moving the "T#" extruder motor. Attachments to e-mail replies to Github don't get published. Via USB, SD-Card, or OctoPrint? to your account. And you have the option of putting the extruder start g-code at the beginning, the end or somewhere halfway your normal start-up sequence. A bug with that was recently found here too: #6847 It seems to be incorrect if the adhesion extruder, support extruder or infill extruder is modified (whichever gets used first). I tried to reproduce this part of the issue on current master, but for me it kept replacing it correctly. With only the information that is currently in the issue, we don't have enough information to take action. Start G-Code¶. Open both STL file, right click on model and select “Dual extrusion merge”. After reading many of the threads here and abroad, I put together a start GCode script for a two extruder printer. But after the second time, the start gcode is not repeated and the part starts to print. 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? Here is the project and corresponding gcode it created before I deleted the duplicate entries. You are receiving this because you authored the thread. {machine_extruder_start_code, initial_extruder_nr} puts in the wrong extruder, It always uses extruder 0. G1 Z0.2 F3000 ; get ready to prime if i turn on my Heatbed ether through cura settings or through the start.gcode itself my extruder will heat to the heatbed temp and the extruder will remain off dual extrusion same problem Re: Duplicator 4 and Cura (WORKING) I am trying to set up the machine settings for my BigBox Dual. You attached the project to an e-mail reply. <. M115 U3.1.1 ; tell printer latest fw version It's designed for Multimaterial Y joiner. START.GCODE. I think I may have figured it out. This command behaves differently for DUAL_X_CARRIAGE vs. DUAL_NOZZLE_DUPLICATION_MODE. 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. Cura 15.06 removed the ability to manually add start/end GCode in the GUI, but you can still do it by editing the machine specific .json file for your printer which includes separate lines for start/end gcode concatenated onto … Start Gcode: This is wanted behavior. Please reach out if you have or find the answers we need so that we can investigate further. Note though that the start g-code specifies that it draws two lines.

Gcode done twice, but nothing bad happens/printer not damaged. project and gcode demonstrating this bug. Maybe that's what you're seeing? 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. There is a tab for Extruder1 and Extruder2 in Machine settings but if I edit the start code in one of these tabs, it has no effect on the generated gcode. 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. The text was updated successfully, but these errors were encountered: How do you print? A while back I tried using Cura as a slicer but ran into issues and resigned myself to my fate of using the most up to date version of MakerBot desktop. paukstelis mentioned this issue Mar 10, 2019 Extruder before/after gcode missing #5412 {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. start gcode Slic3r single left.

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. The purpose of the start.gcode script is to prepare the 3D printer for producing the desired object.
