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.

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.

A USB powered LED light stick.

It’s a white board with 8 LEDs, encased in clear plastic and has a standard USB type A connector in the end

A USB light stick in the pillar cover mount at the base of the pillar on the FLSun Super racer so that the LEDs are facing toward the bed

The USB extension cables wrapped together in a red and black cable wrap material and plugged into two USB power outlets, which in turn are plugged into single receptacle power outlets with a switch, which in turn are plugged into a power bar.

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.

The clip is a rectangular shape with rounded ends, with a curve shape on top to hold a USB cable.

It lives!!!

Let the calibrating begin!

#3DPrinting #FLSun #FLSunSR

New fans are installed on the effector housing.

I’m ready now to put everything back together, re-lube all the ball joints and linear rails, and tension all the belts.

Then I can start some calibration prints 🤞

The stock FLSun hot end effector assembly with three small fans, one for effector cooling and two for parts cooling.

The FLSun hot end effector housing with two larger 5025 direct blower fans installed on each side along with new fan ducts on the bottom meant to better direct air to the part as it’s being printed.

The upgrades continue!

Got a few minutes free tonight so I just installed the magnetic sheet to hold the PEI build plate.

Wiring these fans for the JST SM connectors is a bit of a finicky process huh?

Both newly wired fans are tested and working though 😊

Both pins on the end of the red and black wires inserted into the black male JST SM connector.

New extruder is built and installed on the stepper motor.

Still have a couple of more upgrades to do first before I print anything.

One upgrade at a time and tweak as I go? Naw let’s just do all the upgrades and start from scratch dialing in settings lol

#3DPrinting #FLSun #FLSunSR

A black OMG v2S extruder installed on the arm bracket that will attach to the frame of the 3D printer

Stock extruder is disassembled and cleaned so I can put it back together for storage.

Now I need to build the new extruder so it will work with my stepper motor.

- Hot end assembly (still assembled)
- Stock stepping motor

The top piece is off showing the inside with the silver push bar and two black gears.

This unit needs to be assembled with additional parts/gears to work with the stock stepper motor of the FLSun Super Racer

The company that made my printer says they might send me free filament if I post a pic of their product. And also this pic is kinda cute.

We will see if they hold up their end of the bargain for a Mastodon post.

Me and some kids watching my flsun printer lay its first layer of a print in a messy corner of shedStudio

I now have a stand/holder designed for this case.

https://www.thingiverse.com/thing:6755438

For this I used CadQuery (rather than Python on top of OpenSCAD). It's my first project with CadQuery; there are things I quite like about it, and other things I'm finding klunky, which probably means I'm using it wrong for those things. I expect it will get better as I get more comfortable with it.

#3DPrinting #FLSun #V400 #SpeederPad #case #stand #holder

A rendering of a 3D model of a stand for a piece of electronics called a "SpeederPad", which is a small computer and touchscreen used to run some 3D printers made by FLSun. The stand holds the unit up off the table, at an angle, and has ventilation holes.

This view is from above, showing the pocket the unit fits into so that it is secure and will not fall out.

The part that's insane is that all 3 panels install this way. There's no hinge for the front panel, which should be a door that swings open. Having to slide the front panel up to get at the print bed makes no sense at all! And I'm not sure as I haven't tried it yet, but you would have to take the top of the printer off to do this?

Am I missing something hugely obvious here?

So, I decided I wanted to try using an #enclosure for my #FLSun #V400 to try to reduce warping issues. I bought the official kit - it's fairly nice bulbous #polycarbonate panels for each of the 3 sides, and shouldn't have any issues with the effector clearance.

Installing it...

I got an FLSUN V400 as my second 3D #printer after frankensteining my first printer to its limits. It's nice.

It runs (unfortunately not stock by default) Klipper, and comes with the "#SpeederPad", a small ARM-based touchscreen computer to run the UI and the #Klipper software. Also unfortunately, it only has a WiFi connection.

Except... the board inside actually has an unpopulated place on the board for an RJ45 ethernet port.

@austinphilp @johnke

Not familiar with that one. My first was an FLSun QQ-S Pro #delta. A lot of the stuff I did on/to the printer was various #upgrades and changes and fixes and whatnot - but there were also enough clogs and other simple problems that just meant an hour or two here, an hour or two there... it adds up.

At this point, it's only about 50% FLSun 😉

Bought another #FLSun recently. Only put the included baby spool through it so far, but zero problems.

@koz

I think it is all due to the "Stae of #opensource in #3dprinting" by Josef #Prusa that led to this.

We have 3 routes we can take now. #Closedsource #Bambu printers, semi-open #Creality (which is just a copy of everything out their basically), and #Opensource #Voron.

I am disappointed in Creality just becoming copy-cats and also releasing stupid stuff like the Creality #SonicPad and locking it up as much as the #FLSun 400 controller.

But companies like #AnyCubic aren't even trying to copy #Prusa. They are just cntrl+f'ing them by now.
