    Homies don’t let their homies use soldered wires in screw terminals. Solder drifts and could be a fire hazard. Pla also drifts over time so you’ll need to constantly re-tighten all your bolts. It’s likely that any pla part under constant strain like the idler mounts and gantry mounts will shift/warp

      Yup will keep an eye out. This and general warpage were brought to my attention back when I began. I do have one prototype (the one in the last video) that had been printing for a month, and it held up very well with no drift. I noticed some flex at the last minute so I fixed that with the new reinforced z block design so I’m on top of it. I suspect because it’s so THICC what little forces are acting on it just don’t contribute to much drift and all the pulleys are screwed in tight and have a washer to sit on which spreads the load many THOUSANDS of times over just having a screw post cantilever like in the journeymaker design. Time will tell.

      Please avoid using solder on screw terminal wires. This has caused problems with the Ender 3 in the past, leading to burnt terminals for many users.

      @@TheGiuse45 Incorrect, it does, under pressure it very slowly 'flows' and deforms, shifting away from the compression forces, the connections becomes looser and higher resistance, starts to heat up, the solder oxidizes and flows away even more, then fire/melting/charring from the wire insulation.

    Looks like a very well thought out design. The tinned wires in a screw terminals is a big no no, especially on power wiring. I'm also not fond of using a screw gun without going back and hand torqueing. Cool printer but having 3 printers with this build volume already I can't justify building one....yet.

      @lemontron  20 годин тому +3

      You do tighten the nozzle hot, but the cold side doesn’t thermally expand to the point where it affects leaks. Yep issues with serviceability are definitely there, specifically when you need to replace the heater or clean the hotend. I really just made some calls in the name of miniaturization, it’s all calculated for cost/benefit but it’s nothing a little more RnD can’t fix. Sample Name actually linked me a SMD finger that allows the heater to be installed toollessly.

      Lemontron is the newest positron style printer and it shares many design decisions. Same print volume, but half the price, internal extruder as opposed to external, unibody chassis as opposed to plate construction, 0 cnc parts as opposed to heavy use of cnc parts, it has a bed mesh probe, and internal psu as opposed to external brick. I hope it proves to be a big innovation over the previous positrons.

    @FuttFel 14 годин тому +1

    Is there a reason for going with screws that go into plastic, as opposed to just using more heatsets? Screws that go into plastic is almost a one-and-done type of deal and are extremely easy to strip out. The base is such a large print that it would suck to have to re-print the whole thing because one or two important holes stripped out. Such as those for the rails. Also, the kapton tape used later to hold down the wires, perhaps one addition here could be U-shaped channels that will accept those really small 2.5mm cable ties?
    Aside from that, fantastic work! Really looks like you one-upped all the other Positron variants and made one that's actually viable for most people to make! If I didn't already have a full kit and all parts printed for a Micron+, I would build this instead.

      * portability - it goes anywhere and you don't have to fuss with someone else's printer.
      * Small living, tiny house, van life (that's me) , RV life, tiny city apartment
      * Remote work. The rare few where printing on the job anywhere could speed things up a lot.
      * It's badass
      * Bring the printer to your friend and fix their tool/issue with them instead of the back and forth, so long as it's a short print.

    • @ljadf
      @ljadf 2 години тому

      * Portability - an A1 mini is pretty small, if you aren't concerned with packing it up, and putting it in a backpack, you're fine. You'll also have reliable prints at a higher quality. Small living, same reason, and no need to spend a couple of days assembling it yourself, more likely than not forgetting, damaging, or misplacing something. If you love building stuff, go for it, otherwise don't do it.
