Very unsatisfying printing results


#21

Thank you. I did a lot of amazing prints with the Flux in the past. Perfect layers, top adhesion, no warping, no clicking, no gaps, straight lines. And I printed and sliced everything with Flux Studio. Here are just a few of them:

Guys, I promise you are not alone in trying to figure out why your machine that used to make beautiful prints suddenly cannot manage to get the infill to meet the walls on simple boxes.

It is 1:30am here and I am reading your posts and trying everything and testing and doing everything I can and getting the same results you are seeing.

Something is wrong in FLUX Studio or all of our machines are collectively wearing out at the same time.

I wish I had answers but I don’t at the moment. I’m trying everything I can. My old faithful leaky printhead died. The new (rebuilt) one I just got back from FLUX a few weeks ago is already melted and starting to leak, and I’m struggling to get any kind of consistency in good prints.

I get one good one from FLUX Studio, then it goes to crap for no apparent reason. I switch to S3D and it works great for a print or two, then just turns to a mess. Then I switch back. No consistence at all. I’m currently in the middle of the ‘pancake’ testing that was written up in another post.

Needless to say, I am extremely disappointed too, and I don’t have any idea what to do to make this machine work like it used to.

If the pancake test and remedy works for me too, I will post again.

@BoozeKashi Good to know we’re not alone. Is it possible to bypass/replace Flux Studio completely in our printing workflow? Maybe print directly via S3D? Is there a generic USB driver which can be used?


#24

Yes it is possible via flux_robot from the SDK, but it isn’t easy to set up and won’t exactly work native with S3D like you would expect without some coding.

@pfeerick and I have both looked at it, but speaking for myself, I haven’t had time to go much further than just checking that it was possible when he stumbled upon it. I am not sure if he has explored it any further either.

Jim (Proclaim) has mentioned that they are ‘working on something’ similar when we inquired but he couldn’t elaborate yet. This was actually fairly recently, so pure speculation, but I suspect FLUX is going to give us a direct print capability or something closer to it soon.

Edit: some linkage if you want to play http://dev.flux3dp.com


#25

Yes glad I am not alone.

I would have a look at the SDK but my programming skill are close to non existent.

So I suppose the upgrade kit usb cable does not work with S3D? I did not try that yet…


#26

I tried the upgrade kit usb cable with S3D. It’s not working, the printer is not recognized. Only COM1 and COM2 can be chosen. But I expected that before.


#27

Current result of my print. It doesn’t look much better.

Could the STL file be the problem? It was my first attempt in Tinkercad. But I checked the file with S3D, no repair required.


#28

Not sure if it is the STL file.
From some of the problems I have seen with models on my Flux I would guess more hardware or software issue.

I have a feeling that it might be related to some firmware / software setting which are acceleration and jerk related.
I am not sure if we can change them (at least I never did so far) but I will have a look tomorrow.

However if you want you can share the file and I will print it on my to see if I have the same issues.


#29

That would be very kind, thank you! Here is the link to Thingiverse: https://www.thingiverse.com/thing:2321036

Printing just the lid would be enough testing imho.

Thanks again.

Using my main in vain again Booze? :laughing:

Yeah, I look at it, and was thinking about playing with it further to make an uploader script thingy… but as you say, Jim said they have something in the pipeline… so decided to not bother with that for now… be different if nothing happens and six months goes by… but I doubt it will take anywhere that long.

I’d take wear out of the equation… my baby hasn’t had anywhere as much use as yours or Luans, and it spit the dummy after the upgrade kit was put on… and I do point the finger squarely at the extruder motor settings not being dialed in as far as under/over extrusion related problems and artefacts. Bed calibration / pancake is another issue, but that may be more machine specific?


#31

I just do a quick first layer test. Here is the result.


#32

I have another test. Here’s the result.


#33

@goldensnake Thanks for testing. I wish my Flux would print like this!


#34

same here looks better than mine, I guess something is off :frowning:

Well I think I will have a look at the belts it kinda feels like they dont have the same tightness.

Not sure what else to try… just have to see if I can figure out how to do it… has anyone done it on his flux?


#35

@Tyrolean

Nothing wrong with the model. We just have to get your settings straightened out I think.

I used only FLUX Studio, with Cura2 slicer. Glass plate and glue stick. I think it was around 20% or so when I stopped it. I had settings on .2 layer height, .25 first layer, 20% infill, triangles (obiviously…) 2 shells Corners are square, no warping at all. Very slight elephant foot going on with first layer, but that would trim off in 1 pass of a hobby knife.

The full settings I am using are the ones posted here by @mc_ott a couple weeks ago, the only changes I’ve made were to turn tilt detection back on for testing purposes, and I have bumped up the infill_overlap = 0.18 I can repost them if you need them. It is easiest to do a Reset Config, and then go through and make the changes from his PDF as he conveniently highlighted them. It really makes Cura2 in FLUX Studio work well.

This is on an original Kickstarter Delta without the upgrade kit and over 1600 hours of printing. You can do this.


#36

@BoozeKashi Looking good! It would be great if you could post your complete settings (or send it via pm).

I also have an original Kickstarter Delta but with upgrade kit. Where can I see the printing hours?

Thanks for all.


#37

To see your printing hours, in FLUX Studio, go Machines, then select your machine, then Toolhead Info:


You’ll get the hours for that Toolhead. If you have more than one, you’ll have to check each and then add the hours.

For the Cura2 settings, download this PDF file from my Dropbox. (PMs don’t allow attachments here)

*If anyone else wants to grab the file, feel free, it’s open to the Public, and I’ll post it in the FB Files Section too.


#38

Does anyone know if the Flux supports the gcode M201 ?

Have been playing around with acceleration and jerk control in Cura 2.5 and so far it seems like the Flux ignores it :frowning:

@proclaim can you confirm this?


#39

@Tiwaz and @Tyrolean
I found the printing tip from S3D forum that might help you on finding a problem on the printer.

@goldensnake

thanks I will have a look
however if that is one of the issues I don´t think we can do much about it on the Flux

Also, if shifting is causing your parts to be off:
-If your belts are too loose, the motor could be turning and not turning the belt with it
-If your belts are too tight, the motor could be turning and once again, not turning the belt with it
-The voltage to the stepper motors may be off
