  1. When I setup a print with multiple items, and use the "One at a time" special mode, the first item prints fine. But the second item and every subsequent item starts slightly higher than the first, which leads to them failing because the initial layer doesn't go down properly. This has only been an issue on my delta printer, not my Ender 5. I'm not sure what causes this, but I can confirm that the position of the print head is still accurate after that first print. The Z hasn't changed at all.
  2. I mean, that's nice and all... but it's not in the gcode file and it's a manual process that I need to remember to do on purpose.
  3. There's a comment block at the bottom of gcode files that shows some of the settings that were used when generating that file. But many of the settings are missing, and some of them are things like "default material temperature" or "settings from profile XXX", either of which could have been modified countless times since that gcode file was generated. It's also difficult to read, being compacted and line-wrapped into a square block. Is there a way to automatically include ALL the Cura print settings as an easily readable comment in gcode files? Not just the reference it used to get a value, but the actual, computed values themselves? It would be really great if I could go back to an old gcode file that I know turned out amazing, and quickly see what settings I used for that specific file. If there's a plugin for doing that, I'd love to learn about it.
  4. Thank you! I was doing it while signed in, and it wasn't updating it online. But doing it through the web site seems to have worked.
  5. I uninstalled a couple of extensions that I no longer need. Now, whenever I open up Cura on any device that's logged into my account, Cura complains about "Changes detected from your Ultimaker account" and tries to get me to sync material and software packages, which inevitably re-installs the extensions I don't want anymore. I appreciate the ability to sync settings between devices by using an online record of those settings, but this is getting annoying. It's been doing this since 2 versions ago (4.6.x, 4.7.0, and now 4.7.1). How do I get it to update my stored online settings with my CURRENT machine settings?
  6. Good call! Tried it in Slic3r. There's absolutely no under-extrusion when I print a file from there, and I'm not adding any extrusion in firmware. In fact, the top surface came out perfect, no issues whatsoever. I was even able to turn off some of the retraction and pressure advance hacks that I've been using to try to deal with this issue. Slic3r is giving me the kind of print quality with my current setup that Cura used to get me with my old setup. The reason I don't typically use Slic3r is that it doesn't have any enclosure temperature control, and I'm just much more familiar with the Cura workflow. So now the question is, why is Cura causing so much under-extrusion with my current setup?
  7. Ender 5 Pro with a Duet 2 Maestro board, E3D Titan extruder driven by a 0.9 degree motor direct over a E3D Volcano hotend with a 0.6mm NozzleX configured for 3mm filament. I used to run a BMG extruder with a 1.8 degree motor through a bowden tube into a Micro Swiss hotend with 0.4mm nozzle setup for 1.75mm filament. I had the extruder steps/mm set to 420, and that worked perfectly for months. Never had any extrusion issues. I could command 100mm of extrusion through the Duet web control interface, and that's exactly what I got every time. Prints came out perfect, or if they ever failed, it wasn't due to extrusion issues. Now with the new setup, I went through calibration steps and came up with 840 steps/mm, which makes sense since I switched to an 0.9 degree motor. Once again, if I command 100mm of extrusion through the web interface, that's exactly what I get every time at any hotend temperature within 10c from the filament recommendation and at any extrusion speed from 1 to 4 mm/s. But prints from Cura are coming out terrible. There's very obvious under-extrusion throughout. Gaps between lines, fragile infill, holes in the top skin, it's all miserable. If I increase filament flow by 20% through the web interface during a print, the issues mostly resolve themselves, though the top skin still doesn't look anywhere near as nice as it used to with my old setup. But +20% seems like a heck of a bandaid. I'd love to know why Cura isn't asking for more filament flow. I've confirmed that I have the nozzle size set to 0.6mm, and the filament size for the extruder settings is at 2.85mm. The filament itself measures in at exactly 2.85mm and seems consistent. It's a good quality ABS (Polymaker Polylite ABS) and it's dry. What would be appropriate steps to take to diagnose this issue?
  8. I couldn't, the setting didn't exist. My printer is an Ender 5 Pro, so when I set it up initially (long before I switched to a Duet board), I used the Ender 5 preset in Cura. This fills in a bunch of printer settings, but it also automatically hides some of the printer settings from the Machine Settings and Extruder tabs, including filament diameter. Near as I can tell, there's no obvious way to make those settings appear. Since my last reply, I've created a new custom profile from scratch, and now that profile allows me to change the filament diameter for the extruder without needing the Printer Settings plugin.
  9. Thanks, I finally got it somewhat working. I tried Slic3r, and the kickbacks disappeared. Of course, the result was typical Slic3r (wide line spacing that looks awful), but at least it showed me that Cura was still generating code for 1.75mm filament. I had already done the setting change you suggested, but it's not enough. I had to use the Printer Settings plugin to show me the hidden settings, and use that to tell it that my printer now uses 2.85mm diameter filament. Now everything works as expected, including adding new material to the list. Not sure why that setting isn't normally changeable within Cura... not cool.
  10. I run an Ender 5 Pro with a whole lot of modifications (Duet 2 Maestro board, linear rails, different extruder, all-metal hotend, etc, etc). It's been running great for months and months and giving me beautiful results. Until recently, I was running it with a Micro Swiss hotend with 0.6mm nozzle fed with a BMG extruder through a bowden tube. For my most recent project (huge print with many, many pieces), I ran out of the filament I was using and that filament is now discontinued. I couldn't find inventory for that filament in 1.75mm, but I was able to find a few reels in 2.85mm. So I decided to switch the printer to a 2.85mm setup. I went with a Titan extruder and V6 hotend with capricorn bowden tube. I also switched to a 0.9 degree motor to increase the accuracy since I figured I'd be extruding 2.7x slower than before. Everything is mounted and seems to function. As far as I could tell, no firmware changes were required other than small changes to the thermistor settings and adjusting the e-steps to accommodate the 0.9 stepper. I doubled the e-steps, commanded 100mm of extrusion, and it was spot on (I guess the BMG and Titan have exactly the same reduction). I then auto-tuned the hotend heater and all seemed to work right. Then in Cura, I went into my printer settings to change the extruder to 2.85mm... and that's where everything went downhill. First, all my custom materials disappeared from within Cura. This isn't such a big deal since all my custom materials are 1.75mm anyways, but when I tried to add a new material, the "Create" button did nothing. There's no way to add anything to the list. So I just entered my temperature settings manually into Cura, sent a print job to the printer... and the results were awful. At 0.1mm layer height (which was accidental, I wouldn't normally print that thin with an 0.6mm nozzle), the surface was full of blobs and zits and over-extrusion. I've done 0.1mm with an 0.6 nozzle before, and it never came out that ugly. During the entire print, the extruder was doing a bizarre kick-back every few seconds. Like the pressure in the tube was too high and forcing the extruder and stepper motor back. At first I thought it was just the retraction that was more audible (this extruder is way more noisy than the BMG was), but this kick-back was one-way only and happening right in the middle of straight lines. I retried the print with 0.2mm height, and the exact opposite happened. It under-extruded massively and came out with all kinds of gaps. Though this may have been because I turned the hotend temperature down a little. Meanwhile, the kickbacks continued throughout the print. I'm getting the impression that the extruder is pushing filament way too fast, and I'm not sure where I'm supposed to adjust that. Is this a firmware thing? A Cura thing? Why can't I add materials? I'm at a loss...
