Everything is hosed with silicone. Except they first hosed it into the male connectors, then inserted them. The level of fun getting these fiddly connectors out was somewhere around sticking hot needless in a tender spot of your body.

Then the stupid Youtube video skipped multiple critical parts. I scratched my head with the cover's removal, but there's more screws than shown in the video. Also lot of these screws had completely randomly torqued. Some were about to fall off, some were tightened with the force of a thousand suns. Multiple hex screws had signs of the assembly worker's screw driver slipping and the screws were extremely painful to remove.

In the end it took around 40 minutes to get to the extruder gears, mostly because of incorrect documentation, absolutely horrible, service-hostile design and silicone or hot glue everywhere. Plus hex screws that were now nicely rounded inside.

#3DPrinting annoyance...

I have an #FLSun #V400 delta printer. A few upgrades, including to stock Klipper. I'm happy with it.

The issue: it's got a filament runout sensor up at the top of the print volume, right after the filament comes down through the top compartment of the printer, which houses the MCU and stepper motors. That works fine for detecting the end of a reel of filament.

But it's basically useless for detecting a filament break, because every break I've had has been between the sensor and the effector/hotend. The sensor happily indicates "filament good" while the hotend uses the remaining ~50cm of filament and then continues to print nothing, while cooking the leftover plastic in the hotend.

What do others do about this? Should I be moving the runout sensor to the effector, just on top of the extruder? Or I've seen what appear to be fancier sensors that detect filament movement, rather than being just a simple presence switch. Anyone have any experience with those?

I appreciate any thoughts from the more-experienced printers in the fedi. Thanks!

It doesn't stop until the motor-timeout is hit, *or* I manually disable motors - at which point the ticking instantly stops.

Any idea why the steppers are still being activated after the print is complete? Does it serve a purpose? Seems like a waste of energy, and needless stress on the hardware.

Running vanilla Klipper version v0.12.0-290-g14a83103c on an #FLSun #V400.

Bed lighting upgrade is installed!

This should make it a lot easier to see the first layer being printed versus using a flashlight.

I have the two front lights on one switch and the rear light on a second switch so I can choose which ones I want to turn on.

Printer calibration is essentially done.

Might make a few more minor adjustments as I go but currently it’s printing well enough for some functional prints like these USB cable clips that I’ll stick inside the bottom of the printer housing to hold the USB cables in place for the LED lights in each pillar.
