    According to ratrig the parts are printed in ABS. I typically use a lower temperature (compared to print temp) when installing heat sets as it's easier to control how they go in.

    A quick solution I found to keep the trim diffuser in place was to bunch up a piece of a paper towel and stuff it in there. You can also back out the two m3x8 screws a little bit to apply some extra pressure to the paper towel.

    I have to agree with marc, I printed this with High quality ASA on an H2D at work, 0.4 nozzle, 0.2 layer height, high quality, slow speeds, part came out perfect in 1 shot. Started threads by hand, finished with a wrench. I decided to self-source for all the printed parts, and im glad I did, all the parts that did come with my kit are only just serviceable and only just in spec, not what I could consider the highest of quality.

    Nathan C - Open Reply

    Clearly the printers used are

    1) not calibrated correctly

    2) not set at the right precision for this part where threads are involved.

    I reprinted on an x1c with 0.1mm layer height. All other settings as recommended. It threaded perfectly, first half smoothly by hand and the rest with my 10mm. Perfect fit, not too tight or loose. No need to scale up or down the print here, the STL is perfect as is, all printer settings. I would appreciate RagRig fixing this, yes I have a printer and was able to get past this but the point is I paid for this and it's not usable. Part of my product cost, shipping cost and duties even if minimal on one part went towards something unusable. This is also far from the only part out of spec, another one needing a reprint was the toolhead toolboards, their off-spec caused bad alignment with the hex standoff. I could go on and on.

    It's worth beating this dead horse. I reprinted these using ASA and they fit perfectly the first attempt. Mind you, I used a .1mm layer height. This part never should have shipped.

    The problem is the threaded area of the print needs to be printed at .1mm layer height. On my prints (IDEX) both had many of the threads not even connected to the print. Just loose strands of plastic not adhered to anything. That's because at .2mm layers or larger they have nothing to connect to on the previous layer.

    Or if Ratrig made the walls thicker, they could just print the hole to slightly over the ID of the thread and then the user could self tap the bowden pass through connector. This would not require the fine layer height.

    Bill - Resolved on Release Reply

    This part needs work. The part I received was printed with such tight tolerances that merely screwing the PTFE adapter in a couple threads caused it to delaminate and fall apart. The tolerances should be looser, and the walls around the adapter should be thicker to handle the stress.

    Exactly the same. Print quality of the parts is so attrocious that it was the exception for any of them to work out of the box.

    Had to do plenty of drilling, milling and filing to at least make it functional.

    Mathis -

    Had a similar issue. Managed to get the part assembled (twice for the IDEX kit), but I had to go incredibly slow and gentle. It took a lot of trial and error to get the fitting to thread in straight and I don't think I have it seated all the way in the hole, but I stopped short when it got extra difficult to continue.

    This one has been the worst, but this feels like a common theme with the printed parts in this kit - they have all felt rushed and not well printed/inspected. Overhangs and surface finish have been mediocre to bad, and several parts have been warped or not fit correctly.

    • Tighten the M6x12 screw to secure the guide assemblies and PTFE to the frame.

    • Take care not to over tighten the screws as you can damage the printed parts.

    IMO do NOT place the second guide. Only use one, and put it about 1/3 the distance up from the bottom. This results in a much smoother transition for the filament to pass through and much less resistance for the extruder to pull against as you print.

  38. It is recommended to route the PTFE filament guide as shown. If you are assembling the IDEX, go back to Step 32 and complete an additional filament path assembly, on the opposite side of the machine.

    Why not put the filament at the top of the frame vs this super long path???

    Largely because a typical cabinet height is 30 inches, plus the 38 inches of height of the 500, would put the filiment somewhere around 6 feet in the ait, above what many can reach.

    would be nice to have a printed part to attach PTFE tube to spool holder

    This part exists on printables so do a search for it.

  39. Piano Wire for Umbilical - 1000mm x 1.00mm
    • Piano Wire for Umbilical - 1000mm x 1.00mm

    • M3x5 Set Screw

    • The Piano wire need to be cut to length for you machine:

    • V-Core 4 300 - 650mm

    • V-Core 4 400 - 750mm

    • V-Core 4 500 - 850mm

    • Use a strong set of cutting pliers, as the piano wire is super stiff and can break small pliers.

    The 300 size does not need any piano wire, just use the included black wire wrap by itself which is enough to support the harness. Much less likely to cause unwanted movement of the nozzle due to the piano wire creating a twisting force on the top of the toolhead assembly.

    The IDEX hardware pack contains a second 1M length of piano wire (and umbilical cover) fyi

    Bill - Resolved on Release Reply

    never assume that you will receive 1 meter of the piano wire, so measure the whole length of it twice, just to ensure the correct position to cut according to your machine. Also, you can give 3 to 5 mm beyond the specified length, it's better that than buying another wire.

  41. Insert the other end of the piano wire in the designated hole on the EBB toolboard mount Be careful, the piano wire is super stiff, do not allow it to swing freely as it can hit you and create injury. Once installed it should look like the picture, the piano wire will provide support to the USB and power cables, improving Input shaper results

    Lesson Learned: Don't heat piano wire to melt plastic while inserting into tool head. Overheating will make it more brittle and break. Broke off 20mm of wire in tool head.

    Easiest way to install is using a drill. The hole is not straight, do not recommend a drill bit if you have the size. Instead use the wire as a "drill bit". Insert one end into drill chuck and sand the far end to a point (like preparing tungsten for TIG welding). Insert pointy end into tool head hole and "drill" in ~35mm. Feed the wire with hand into toolhead, shouldn't have to apply much force, the wire will dig the hole.

    There are definetely a few issues with this doc that are not addressed in other sections, such as what to do with the piano wire with an enclosure, or the length when all the way to the back of the plate.

    I don't know if umbilical height is going to be an issue with a top enclosure panel, but my gut tells me yes. I'm ordering additional 3030 extrusions to build a riser. Additionally, I will install some cross bars with lights for better chamber illumination.

    3030 extrusions are available from McMaster Carr. Black anodized to match. Along with all of the joining solutions you can imagine. It appears an additional ~200mm of height would be required to clear the umbilicals.

    I gotta say, I was really pleased with the quality of everything until these last couple steps. The umbilical frame insert should probably be an M4. The M3 came right out with virtually zero pressure. I melted it back in with a ton of CA glue.

    I cut my piano wires to the required 650mm length for a 300mm machine, and I notice that when the Y axis is moved all the way to the rear the wire loop extends quite a bit above the top of the frame. Is that going to be a problem later with an enclosure top?

    Denver Hull - Resolved on Release Reply

    I checked the CAD for IDEX before doing mine. IDEX uses the same umbilical mount (and only the one). It was pretty hard to get both wires in, but managed it with pliers. The bottom of the channel is only a layer or two, so shoved until both wires poked out and then shoved them back into the part slightly. Then tightened the set screw. FAR easier to do with the mount removed from the chassis.

    Do I need to install 2 for an idex?

    Thomas - Resolved on Release Reply

    How deep is the hole in the toolboard mount for the piano wire? Mine didn't seem to go in more than 6mm or so.

    Bill - Resolved on Release Reply

    Yeah that isnt happening for me. All 3 toolhead mounts barely took 3mm and I had to drill the holes to get it to even 6mm. 35 just isnt happening on mine!

    Matt -

    If you take a look at the CAD Files you can see that it's about 35mm. 6mm is not enough at all.

    That's about right.
