  • I will second this, even though I also agreed with “build a Voron”. My 2.4 is a massively capable printer, and has a lot of quality of life features like actual mechanical bed leveling, but odds are your first build will have some teething issues. My extruder motor didn’t have a fully aeat wire terminal in its factory harness so it extruded inconsistently. Thankfully it was easy to find and fix. I’ve had a few wire breaks in my cable chains because I didn’t leave enough slack in the runs. The build itself is also long, but I did find it to be straightforward. Vorons are also Vorons, so the modding is endless.

    Printer as a tool? Prusa. Maybe also Voron, especially if you want print volume/raw speed/quality of life. Printer as a tinkering device? Voron. Ship of theseus as you upgrade your way to a better printer? Ender.




  • PrusaSlicer is a fork of Slic3r Bambu’s slicer is a fork of PrusaSlicer Orca Slicer is a fork of Bambu’s slicer and also pulls in ideas from super slicer (another PrusaSlicer fork).

    In other words, they all share a common lineage. Each adds quality of life improvements over the fork, at least in theory. It’s possible those quality of life improvements will make it back upstream to the thing that was forked.

    As for specific examples, Orca Slicer has a somewhat different set of tuning parameters, some unique-to-it quality things like scarf seams, built in tuning prints (temp towers, EM multiplier, pressure advance, a test to find your max flow rate, etc) a revamped UI, etc. I haven’t compared the two in a while, so it’s possible that some of this has made its way upstream by now.





  • If the print didn’t come off the bed, I don’t think adjusting z-offset will help. As prints get taller, if you’re running into issues with warping the corners will start to curl up.

    Your printer definitely missed some x or y steps. Whether that was due to your drivers getting too hot and just that, or the extruder running into the print. Have you ever seen your printer do this:




  • So, the biggest difference in quality is the steel and hardness.

    My question was rooted in how you would know the quality/hardness of the steel at time of purchase - especially as a (fairly) layperson.

    I think my set is dewalt. It included taps, dies, and drill bits for M3-M7. I don’t think I’ve ever used the drills, and the have gotten a lot more use than the dies, but I think I’ve used almost everything in the kit more than once. Before kids, it was cars. Post kids, it’s mostly cheap Chinese furniture my wife buys that I have to chase threads in to get it to assembly well.

    Also, for the record, you can absolutely tap plastic for a reasonably strong thread

    I’ve had pretty good success sizing 3D printed holes to be interference fit. That’s how I designed/printed the bed leveling thumb wheels for my i3 clone. They backed off far less frequently than the stock metal once.



  • Was the hot end pre-assembled or did you assemble it? I suspect you have a mechanical issue, but it might just be e-steps.

    Suggestions:

    Pull the nozzle off, measure say 110 mm of filament upstream of your extruder motor, make a line or attach a piece of tape, extruder 100mm, and see how close to 100mm you are. No nozzle means you can do this cold so you’ve eliminated 2 variables: a nozzle clog and temp. More detailed instructions

    Once you get that sorted, do a PID tune and run the 100mm extrusion test again with your nozzle attached at say 230. Different number? My money would be on a partial nozzle clog.

    Finally, temp tower. Not being able to extrude below 220 seems very weird. How fast are you trying to print?






  • Aluminum’s expansion coefficient is 0.000023m/C. Using my Voron, let’s say the z extrusions are 530mm long and my extrusions go from 22 °C to 55 °C. This means they grow 0.35mm. That’s in total, so the effect at the print head isn’t 0.35mm, but let’s say my gantry rides 25% of the way up. That’s 0.0875mm, which is roughly 3x the z-offset of my last print.


  • 2.4 owner here. Happy to hear some feedback on the SV08, it looks like a pretty good deal.

    Fast (printed something that took 26 hours on the Ender, and it took less than 4 on the SV08

    I’m surprised you saw that much of a speed improvement, but I guess I ran my old i3 clone somewhat fast. My print times were a bit faster on my Voron, thanks to cranking speed and acceleration, but the biggest time savings came from taking advantage of the much better hot end and using a 0.6mm nozzle with thicker line widths (I can cover nearly 2.0mm with two perimeters) and thicker layers (0.3 on most prints these days).

    Finicky for the initial z-offset. Heat soak the bed for 30 min at 65 degrees, then run the automatic z-offset

    Were you homing z with the bed cold? If homing z involves touching the build plate, I could see this. You could probably just adjust your start g-code to accommodate this. One of the nice things about the 2.4 is that the z end stop is bolted to the frame, so as long as your print routine is consistent you can dial it pretty easily.

    That said, just wait until you enclose your printer. The frame will grow in z fairly significantly as it heats up. I’ve not let my printer heat soak, printed a number of sequential parts in one print, and watched the first layer squish getting worse and worse with each sequential part. Eventually filament won’t even stick to the build plate, so you need to tweak z-offset.
