  • You can manually edit the gcode to see if printing white first works out better. Then search for a more repeatable solution if you often re-slice.

    Manipulating gcode looks intimidating the first time but it’s really not that crazy. Cura adds comments to the gcode and you can look up the codes otherwise, I expect Pusa Slicer to do the same. You want to move the whole printing sequence of the white nozzle before the printing sequence of the second black one on the first layer. Keep the setup (heating etc) before that.



  • I own this. It is horrible. If the specs were real it would be great, but the specs are not real. It is a 3k black and white monitor with a fixed color filter over it. That means you need 3x3 pixels to resemble a color.

    I consider it a scam from Dasung.

    Boox on the other hand made a sane black and white display. Much better. I own a Max 2 Pro. Sadly they fail to understand that when you report a display as 20px smaller than it really is over an HDMI port and then rescale the image of the computer display on that, that it becomes really uncrisp. Their suggestion is to use the display with 200% scaling (so you don’t notice as much I suppose).

    Epaper is really promising and nice. However both of these companies should either get some real competition or lawsuits.


  • Depends on the use.

    The screen protector serves as a blue light filter too, it’s cheaper than a display, and fairly thin. That’s a straightforward addition for my use but if you don’t have issues with your phone dropping then you could certainly do without.

    I very much dislike cases and loved the PH-1 for stating that a phone should be solid enough without a case (sadly it did not survive a 50cm drop on a floor so it did not hold up in practice). If you don’t have much issues with your phone dropping then not having a case makes it so much nicer.

    I take more risk holding my phone than I should which means it falls more than average. The price I have to pay is a screen protector and cover. Replacing the display should be easy, but it’d also be wasteful.



  • Not CoreXY but you may want to check out FLSun’s delta offerings too.

    I have an older one and it has served me well. I bought a QQS pro (I think) for tinkering. It worked well out of the box but I could not resist changing the stepper drivers, installing Klipper, changing the hotend, … It still works well, just faster.

    Looking at the few reviews of what they have today I’d buy again but would try not to swap out parts. That or the Prusa you’re looking at.










  • Battery temperature management seems to be a key limiting factor.

    At least a few years ago, and likely still, the reasons and conditions under which the barrier layers in the battery degrade were not super well understood. Heat seems to be a key contributing factor and charging a battery quickly warms up the battery and I suppose not fully evenly within a cell. Not knowing the complete extent of this makes the early LEAF’s lack of actively cooled battery a reasonable choice. Before that, the batteries of earliest Prius cars held up way longer than expected.

    Like with a phone: heat and cold is not super awesome for the battery. It seems heat is especially bad for longevity.


  • I don’t think Xerox invented the computer mouse. It was first drawn out by Douglass Engelbart and presented to the public in the 1968 presentation “Augmenting the Human Intellect” (you can watch it on the present day, it was recorded).

    It was my understanding (which I did not verify) that this was picked up by Xerox and others and that windowing systems evolved from there on with Xerox leading towards Desktop Publishing.
