      Tom is great. We tested print for a few days before shipping. We believe the issue was caused by too tight of tolerance on the ring and impact during shipping that locked it up. Thankfully, Tom was able to fix it. We will address this in the production going forward.

For dual-material prints, it's also very reliable in a way that tool changers have yet to prove they can achieve.
      There is a market for IDEX, companies like BCN3D, Raise3D, Craftbot, and at the lower-end Flashforge and Snapmaker, produce IDEX printers because there is a demand for them.

That, and you could slow it down for use with actual wet ink and vellum plots, very large sizes almost 5'x7' - but with super precision. Multi-color (it had four pen slots.)
      If you'd like to see what it looked like, look up the Xynetics 1000. The plotting head was magnetized to the underside of the top, and needed a little 1/3hp air compressor to push it down enough to where it could move freely. Where the paper was, it needed a giant blower motor to suck the paper flat on the bed and keep it in place.
      What really broke my heart was when we moved offices, the new place didn't have facilities to bring it to (we moved to a 2nd story of an office building instead of a warehouse type place) and we had to get a roll plotter to replace it. We literally dismantled it and sold it for scrap. I think the boss said it was $100k+ when they bought it in the early 1970's.

    Just to clarify, I was assured the printer we're looking at in this video is identical to the production units - but as with anything, there will certainly still be changes to it down the road, whether those be for cost-saving or for improving certain aspects of the machine.
    The software (both the printer's firmware and the slicer) are still obviously a bit rough around the edges, but are much easier to update than hardware - with so few machines in the wild right now, I'm not considering this too much of an issue yet, but I do hope that the printer's tuning will improve over time or with community involvement.

      Almost perfect. No excuse for the lack of Z endstops and of the lack of mains insulation. For the bed part, I think that at this level, the bed *thermal* insulation should be standard as well.
      One little nitpick with the mechanics is that the axial bearings should ideally hold the Z axis screws directly, not through the flexible coupling. However, I see that they used an almost rigid coupling, and the bed system is almost a static load, so I can forgive them for that.

      By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the motor from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
      Surprisingly accurate description of how the closed-loop system works 👍
      On the topic of grounding, the entire frame, bed and moving axes are meticulously grounded, so there should be absolutely no risk of the frame itself ever becoming live.

    so either it was a you issue, or they did something that messed this up, and allows unsafe moves...

    • @MadeWithLayers
      @MadeWithLayers  10 місяців тому +13

      Moving is indeed only allowed once the printer is homed, but it currently does not prevent you from moving to unsafe coordinates. What happened is that the printer was freshly homed, and instead of clicking "Z +25mm", I clicked "Z -25mm" as my exhausted brain thought I needed to move the bed "down", and the printer obliged. Only that this moved the nozzle further into the bed...
      Typically this is prevented with software endstops, but it seems like that feature is not currently enabled, and the loadcell as a Z endstop is likely also disabled outside of the actual homing and probing cycles to prevent false triggers e.g. during filament retracts.

So many people expect these machines to be plug and play without the chance of damaging the print, machine or themselves. We need more education in this hobby that we are operators of a power tool and WE are responsible for the movements of that tool. Yes, the manufacturer should install safety mechanisms, but we also need to learn the limitations of the printer and understand how to keep calm when it starts operating outside of expected parameters. You stayed calm and solved the problem without further damage. Thank you for sharing that experience.
    Great video and very informative. On machines that I operated that had linear rails, they were really good at very fast movement over long distances and short stopping distances meaning minimal overshoot, but those machines were never for small detailed movement. It was designed more for that speed than accuracy. I wonder if this is the best technology for 3D printing accuracy as you showed. I would love a followup video if you ever manage to clean up the quality. I would be interesting to see if its possible and the steps you took to get there.

      For inkjet printers, it's about saving cost by using dirt-cheap, barely powerful enough brushed motors (that have no positional awareness otherwise). Here, the linear BLDC motor would actually be able to position itself without extra help, but would have immensely coarse resolution. So while the resulting closed-loop system and its error-correcting abilities are a nice side-effect, the encoder really is an integral part to make this system work in the first place.

      Besides that, if you were to closed-loop control a stepper, you might as well leave out the steps and just use a BLDC servo which is essentially almost the same control model just the number of phases are different.

Factory calibration is a good starting point but it should always be completed by the end-user after the printer has shipped to them, using their own filament. No printer is going to remain unchanged after shipping and assembly, nor is any printer or filament going to be absolutely identical to the factory ideal.

    Four linear rails... mounted straight to what appear to be anodized aluminum extrusions that are part of an assembly. Those guide blocks undoubtedly have a ton of clearance to make them work without binding. The 3d printing community still hasn't figured out how to use linear rails. A 15 ton vertical machining center can sling around a multi-ton chunk of cast iron on two rails with a single ballscrew. The important part is rigid mounting of the rails to flat and parallel surfaces, which permits using guide blocks with preload (or at least zero clearance). If you print out some calibration parts on this and stick them on a CMM, or even do a cursory inspection of them with manual metrology tools, I bet you'd be shocked at how imprecise it really is.

    The funky pattern on the outside is definitely due to the linearity of the motors. The issue with linear motors is that the accuracy is dependant upon the calibration of the feedback loop *and* magnetic field. And yes, they can be calibrated. But because each axis relies on a big stack of magnets, the magnetic field pattern won't be totally uniform all across the range of motion. You can actually see the position of the magnets is super uneven when you peel back the cover strip. This means that to achieve good linearity across the entire range of motion, you have to calibrate it across the entire range of motion. This is an insane amount of data, and probably not something they have done. Or possibly they have done this at a coarse resolution, interpolating between points. Leading to this slight loss of linearity.
    Also, I can't really tell what the feedback mechanism is on this printer. It should be a high accuracy optical encoder, but I fear that it's a magnetic strip tape encoder on the bottom of each axis rail. At least that's what it looks like from the images I have seen. So not only is that subject to magnetic interference, the linearity is lower to begin with.

    But then the "How can this be improved" part of my brain stood up and started shouting at me.
    Put the magnets in the linear rail truck and a whole series of coils into the rail and then a lot of wire movement will be saved.
    This sort of propulsion system should work very well in the 3D PRINTER market but when it comes to driving a 12mm cutter through a piece of steel then it probably will not have the sheer power to be able to take big cuts at higher speeds to do it.
    For the most part, belt linear drives simply get overwhelmed which is why screws are the go-to for high energy machines.
    BUT for low energy linear movement applications like 3D printing and laser machines I can see this style of machine motion going far.
    And the G0 type commands should be able to really shoot the truck to the end point at a very rapid rate.
    Seeing where and how this technology goes in the next few years should be interesting.

    Strange that this printer is only available in 240v configuration when the price is in US dollars, clearly targeting the US market and ignoring the European market where 240v is more common.
    Although it’s sold out according to their website, it’s offered at a pre-order price of $1,999. Not sure beyond the magnetic drive and the expensive looking nozzle you’re getting for the cost?

    I was experimenting with using a brushless DC motor on the extruder itself (a small drone motor with worm drive). It was fundamentally pretty similar to this - a standard control board feeding step/direction inputs to a BLDC driver. (just different axes, and with the magnets in a circle instead of all in a line). I ended up giving up on that project because the closed loop control wasn't fast enough, resulting in the extrusion motor slightly lagging behind where it should have been. I think it was mostly a limitation of the firmware in the ODrive I was using, I wonder what the high frequency movement accuracy of this system looks like
    In a bldc system like this it's actually fairly easy to measure that with a logic analyser, you can compare the sequence of steps coming from the printer controller to the encoder positions returned from the linear motors.

    the print quality need more deep tuning more than standard open loop system... because closed loop system have their own accleration..
    like if you try to hold the movement of x or y axis to make little late, or stop totally.. the extruder still extruding the fillament that machine is going to give....
    open loop have absolute precise movement at given coordinate... otherwise it will miss step, but closed loop have their own small little late and little faster (to catch up) the given coordinate.. so the extruder will over extrude (late) and under extrude (when catch up) on some area...
    on small print like benchy it's not noticeable, but larger print it will have this issue..
    i hope soon the closed loop system also communicate to extruder to make accurate flow when late or moving faster, it real time data from closed loop system, not like flow compesation that use prediction based the data coordination...

    The linear drive system is very fascinating. Are the encoders on the linear rails optical, or utilizing a hall-effect sensor? (8:43) Calibrating the position of the magnets could offer very high precision positioning, but this would need to be part of the manufacturing process, or via other reference sensor.
    Wondering if WiFi connectivity is related to positioning of antenna? (7:14) I'd suggesting trying with WiFi antenna on wood desktop away from the metal frame. Position looks close to AC power cables, which could be creating noisy RF background. (or metal frame acting as shield). If works on desk away from frame, then repositioning, or giving the antenna ~1cm spacing from metal might help.

    If that is PETG you should have tuned it first. PETG is notoriously hard to print with default settings. It sounded like the nozzle was dragging on the print 21:51 (either that or it's the magnets). The best way to prevent nozzle drag with PETG is to choose continuous infills where lines seldom cross each other - best infill for PETG is gyroid by far. This is because PETG tends to ooz and goes down heavy at the beginning of an extrusion and light toward the end. In situations where you cross lines, the retraction and extrusion have to be perfectly tuned otherwise you get nozzle dragging and accumulation on the nozzle. The ringing is likely from printing PETG too fast. I would have probably done a PLA example if I were going to showcase a printer without tuning it for the material. That was really bold. It took me a determined week and a lot of research to get my PRUSA mk4 making good quality PETG prints: Temperature tower, speed adjustments, infill changes, observations while printing, cleaning the nozzle, changing to textured print bed, adding a silcone sock on the extruder. PETG takes work on any printer to successfully print large surface items like that (without corners coming up and/or layer shifts) and much more to have something with no artifacts.

    Awesome to see PID feedback in consumer 3D printers more and more, this linear setup is pretty sweet! Even the price isn't that bad.
    I really wish stepper motors hadn't stuck around nearly as long as they have, yeah they work... But imagine how many headaches everyone would have avoided if they just simply had some kind of feedback instead of just counting steps.

    @MadeWithLayers re: janky GCFI hookup. Yes! But it's not an electrical / safety code violation, sadly.
    First, the engineers who designed and built this were EEs and MEs, but not electricians. 3D printers fall under EU Directive 2006/42/EC which would normally require this, however an exemption is made for "machinery specially designed and constructed for research purposes for temporary use in laboratories" thus a 'notified body' like the UE doesn't validate the design. That was 18 years ago -- 3D printers are no longer being used just by engineers who are prototyping for products that will eventually be used by the public -- these are products for public consumption in their own right now, and this is the sort of problems that come up when legislation lags behind social and technological progress.
    Sauces:
    5:31 Power cable on the table - probably a type E or F (european), 'AT' power supply cable
    9:31 exterior plate visible, with 'AT' style plug.
    10:12 interior plate visible, with 'quick disconnect' plug.
    RCD is required for any 230v residential plug at the outlet in Europe. Outside of Europe RCD protection at the outlet is not always guaranteed. When the standard was popularized in the 80s, it was with this assumption in mind. You can't buy power cables with integrated RCD due to this shortcoming, so best practices is to ONLY use this type of hookup inside a sealed unit (ie you need screws to get into it once assembled and powered), or at least to have an access cover with the exterior plate having a 'high voltage' warning noting that the equipment should be unplugged before servicing. However, due to the 'experimental' nature of 3D printers, even these standards can (and are) ignored.
    The truth is, while this is a design process failure by the engineers, it's also a failure of government regulation, and your comments that this represents an advancement in what is now considered fairly mature technology stand in stark contrast to this legislative reality. As a content creator who focuses on 3D printing, I feel you have a journalistic duty to provide this context to your viewers, not just the technical tear down (which was solid).

    That chunky build is something I can get behind, same with the lower mechanical complexity due to the linear motors. Especially for models with this kind of print volume this seems like a must-have in the foreseeable future.

    The feedback sensor for the linear motor might have some deviation. You will see some repeating pattern. And some low frequency deviation. The repeating pattern comes from the interpolation is not 100% accurate. Low frequency deviation ist from that the scale is not 100% accurate. Those errors cannot be mitigated by input shaping. It would need some error correction look up table.
    You can prove that sensor deviation by printing one test sample slowly and one test sample fast. The artifacts in the print surface should stay the same.

    I think that oscillations is going to need no a little bit but a LOT of tuning. You have there a magnets don't have any kind of dampening like a belt does, and also the closed loop is going to introduce some vibrations and etc etc etc.

      I cant get over the fact the magnets are just hanging out there, unrestrained, surely this will mean the field is changing with vibration, so that any tuning will only be temporary? Maybe im overthinking that, but i would have thought setting them into something, or potting them in some kind of high temp silicone would be preferred?
