Poor man’s compliance testing: The EnderEMC (#P50)

Such a bold title, such vague blog post – I recently had the pleasure of comparing two very different systems for EMC pre-testing at the lab bench, and one of them gave me an idea.
The two systems were a

  • Y.I.C Technologies EMScanner / EMScanner+ / EMScannerR / EMScannerR+ (with an additional capital R, whatever SEO marketing genius came up with THAT idea), which is a base plate that has all of the signal pickup coils already integrated. Advantage being a fast scan since there’s no moving parts – with the drawback that the raster is fixed in X/Y but also Z direction, and the DUT more often than not needs to be placed upside down onto it.

The Ender 5 PlusPlus on dual linear rails (#E21F7)

A little update on my big Ender.

While I’m indeed satisfied with how the thing works with the somewhat recent upgrade to linear rails on the Y axis (moving the X carriage) in #E21F6 last August, it’s still an old Ender. It sounds like an old Ender and it moves like an old Ender, because despite all the axis changes, mainboard swap and Klipper upgrade, it’s still an Ender chassis with Ender motors underneath.

The other day I had one of these brainfarts at work: We also run machine parts on linear rails, very high acceleration machine parts to be precise. […]

The Ender 5 PlusPlus on linear rails (#E21F6)

In the recent weeks, I printed quite a few parts for work. Some large ones (post incoming) several times, with the opportunity to optimize slicer settings, some others in very large sizes, with the opportunity to tweak the printer to the max settings, even beyond the actual printer bed (390mm along Y!), and some small ones in search for the perfect settings for clear PETG. My fluidd klipper interface apparently only keeps a history of 50 jobs, and that list doesn’t even cover five days.

So after all the software tweaking, I figured it’s time for another hardware printer modification: (Dual) linear rails for the Y axis. […]

The Ender 5 PlusPlus and some toasty PETG (#E21F5)

Time flies…

Six months and I think 3 spools of matte PLA later, the Ender 5 Plus is now pretty close to shape I want it to be. There’s a fully custom panelized and gridded bottom section now that carries all electronics above and the 230V input below the 80×40/40×40 extrusion layer. There’s an optimized holder system around (left, right, back) for the 60cm LED panels. There’s stiffening triangles on every corner now, except for the front top extrusion that is moved down a couple centimeters so the bed/nozzle is visible during setup. […]

Kautschuk Platten Dämmmatten selbstklebend Isolierung XT | 32mm Dämmdicke (WHL #93)

Back to 3D printing for a bit – still lots of changes to the printer, but this one might be interesting to a wider audience: Thermal insulation of the print bed (hard data at the very end of this post!).

You see, the stock Ender 5 Plus printer bed comes pre-“insulated”:

Soo…that is a 3mm mat of black foam material that is glued down with some obnoxious acetone-soluble gunk, and garnished with a bit of aluminium foil on top. Yup, certainly better than nothing, but it doesn’t even cover the entire area, it’s just inside of the mounting frame. […]

The Ender 5 Plus and a pack of RGEEK High quality 6.0 W/mK 200*400mm Thermal conductivity CPU Heatsink Cooling Conductive Silicone Pad Thermal Pads (#E21F4)

Someone was lazy and skipped the last four blog posts
So, let’s jump right in, the Ender series is probably good for another dozen posts. Today I’ll give a quick assessment on the use of silicone pads for the build plate.

The Ender 5 Plus (and many others) uses a 24V 400ish Watt heating plate that is screwed onto a sheet of aluminium, that is in turn mounted to the Z axis assembly of the printer. On top of that, a textured glass plate is “fixed” by some binder clips which I somewhat dislike. There is no solid connection between those – the clips press down on the glass on four corners, but that’s about it. […]

The slightly more silent Ender 5 Plus (#E21F3)

Well, since the printer is running just fine, I used it to make some quality-of-life upgrades to it.
The bottom lid that covers PSU, all the mains wiring and the rest of the electronics has been removed and replaced by a 2 part print (due to size). Several reasons for that: a) Four of the six screws are covered by the additional aluminium frame, so it’s difficult to remove if properly fastened, b) if left unscrewed (which isn’t much of a load problem on the remaining two screws since it is sandwiched anyway), the ends of the large metal piece would be free to vibrate and resonate, c) the stock 40mm fan close to the driver board is terribly noisy and pointless in terms of air throughput, so I would have swapped it anyway.

Ender 5 Plus and the dimmable Lightbox (#E21F2)

A couple of prints later and the lightbox printer is now contained in the intended footprint, with no external spool holder needed anymore. A simple roll with pockets for two bearings, a piece of an old M10 threaded rod, a couple of nuts and spacers, and a small mechanical adapter to make everything fit onto the original Ender holder was all it needed. The LED panels are now connected via XT30 connectors, and a 1-to-3 adapter for these mates with the DC step-up that still needs to be integrated. Not sure if I should use the integrated 24V power supply (as that is maxed out when printing) or add another desktop power brick, and how to (nicely) integrate the dimmer circuit that is just a significantly extended potentiometer from the DC-DC converter. […]

Ender 5 Plus and the lit Lightbox (#E21F1)

Fiat Lux!

LED panel brackets are installed, and so are three “45W” panels that currently max out at 135W with the supplied AC drivers. I’m likely gonna move them to a dimmable solution (a DC-DC converter with external adjustment pot…), but for testing purposes that’s just fine.

Here’s a small print (30cm x 6cm x 2cm) with single-walled towers on each side, made from matte black PLA (Sunlu), still sticking to the black Ender glass printing bed. Clearly this needs a bit more optimization in that all black parts around it could use a more reflective surface covering to brighten up the scene. […]

Ender 5 Plus Lightbox (#E21)

Super short update: I’m doing stupid things that I totally would not recommend to anyone, I’m having fun, and I’m making progress. The extreme humidity right now is a hindrance, but I’m gonna power through and fix things later, in case those ugly mofo brackets fall apart.

The second-hand Ender 5 Plus 3D printer* that I bought recently now has lockable wheels** and at least one side is covered by a 60×60 LED panel*** while power distribution is still unclear****. It’ll replace my old light box***** if things go to plan******. […]
