I would like to use the basic "Ender 3 pro" preset, as it still works perfectly after modifications. Next, I'd like to save any results of the calculations to Cura somewhere as an extrusion multiplier (or similar).

Multiple machine profiles in Cura to represent Hi, what is command line by putty sfw for inverting direction of bondtech qr extruder? I don't know where are the lines showed in bondtech troubleshooting or Configuration. Extruder values are cumulative so you need to initialise it to zero before beginning, hence the first G92 E0. The board came pre-flashed with the firmware for an Ender5, and the other motors work perfectly fine (same with heating and auto-homing). Koby_88. 2 Extruder 1 I am running Cura 15. They (or the person who's maintaining the Cura profiles for Tevo) should update the definition (or you can make a PR to fix it). 1mm of filament and that evaluates to 4. Therefore, you need to mind the header of the Gcode created by Cura (or your slicer). F1500 is a reasonable extrusion speed, with X/Y moving at 25mm/s. Here, enthusiasts, hobbyists, and professionals gather to discuss, troubleshoot, and explore Installation went with little to no issues, but when I tried to print or extrude, the extruding motor was running in the opposite direction. This will place the two parts on top of each other. I've mostly got it working correctly, except that when it switches extruders, it just stops at the last command and calls the temperature change and waits until it heats up before moving. e.

The reverse extrusion was the deal breaker There might be a way to reverse the extrusion through gcode/slicer, I didn’t Header Gcode on Cura. It sorta worked, only issue was when I hit resume it started extruding above the print. I had a couple of issues I’ll list later. r/ender3. But the settings for the profile are different. Discussion I recently got a Mosaic Palette 3 pro - overall a pretty impressive machine (a few places where quality is lacking, but it's got it mostly where it counts) Cura multi-extruder code into single-extruder code + Palette commands to run on the P3P Share Sort by: Best. Insert filament into It's easy to adjust steps/mm for the E axis but you can't reverse direction without loading a different firmware so you have the 2 and the 2+ to choose from.

Hi, first - thanks for the excellent work on cura. That's strictly a text field, it can't perform any logic on its own, it can't run functions. Now in my firmware I added this as a mixing extruder (so I can select mix in firmware etc, move the extruders properly, so that section is fine). To make this work, you'd need to add additional extruder definitions to Reversing the direction of the current in the coils produces motion in the same direction.

To reverse the direction of the stepper motor, you simply need to reverse the wiring to one of the motor windings (it doesn't matter which winding you choose). I am thinking that if I can somehow tell Cura to do a continuous circle motion without constant reversals I could possibly improve Since the Cura Ender 3 profile only allows for a single extruder, you have to create a custom printer. . where the only difference was the start G-code referencing different extruder indexes and priming different number of extruders.

I have created a profile for a printer with 2 extruders in Cura and that seems to load. 4 'steps' from the motor in the reverse direction as the extruder head moved past the problematic spot, then the extruder motor goes back to normal direction and the other areas of the print look fantastic. com/thing:4586978). All that happens to it is Cura unescapes sequences (like \n to a new line) and replace replacement patterns (like {material_print_temperature} to 210). Basically you need reverse a one phase of the motor . How can I set Cura to print objects with extruder 1, and support structures with extruder 2? The only reason I bought the dual extruder printer is to enable me to print water-soluble support structures.
