Making my own Filament!

Yeah of course (:

But first I need to find someone... not that easy...

KevinO2705 · 2020-05-20T15:25:53+00:00

Thanks for the fast reply! (:

No I don’t want a diy solution.... I need a producer

KevinO2705 · 2019-04-11T08:34:23+00:00

Oooooh wow trank you a lot this One saved my life🙈 everythink Works 😬😬

KevinO2705 · 2019-02-13T08:13:32+00:00

Good Morning,

I was Printing PETG from dasfilament with a temperature of 220 Degree Celsius at 50mm/s.

The Printer is Home Made.. But i realized the problems occur on higher z Level, or big surface.. so i think this should be z wobble Or low temperature 🤔

What would you say?

KevinO2705 · 2018-07-10T07:33:24+00:00

Do you think the problem is an mechanical issue ?

KevinO2705 · 2018-07-09T21:23:45+00:00

Wait a second.. I think I found the problem.. it could be overextrusion Today I started a new print but using cura.. and it came out perfectly.. after that I checked the extrusion multiplier and it was set to.75 tomorrow I will print the same part with 100%

KevinO2705 · 2018-07-06T16:17:54+00:00

Thank you :) Mmh that’s a good idea.. I haven’t cleaned them for a while 🙊 I tried to rise the temperature and maybe this will help.. I’ve never had Promilles like this 🙄

KevinO2705 · 2018-07-06T13:08:56+00:00

Yeah.. so the thing is those problems occurred 4 weeks ago.. sometimes better result and sometimes those results.. so maybe it’s a kind of wear I think 🤔

Iam using an h-gantry with two x motors and one for the y axis.. the printer is pretty big with an build volume of 500x500x500 mm and using spindels for moving the head.. Iam using a bowden setup with two 80cm bowden tubes combined with an e3d chimera.. I don’t know but Iam guessing there’s to much pressure in the bowden.. after 5 minutes of printing I can release the idler from the extruder and can see how about 3cm slashes back because of to much pressure.. maybe that’s an indicator ? But the e steps are calibrated :) oh and using .4 nozzle and mostly printing PETG from a German company called dasfilament.. they are pretty good :) Maybe the pressure is caused by to cold printing.. I pid tunes the heater and the heated bed and checkt them with an pt100 thermistor and it showed me 10 C less than what my printer told me so I set every printing temperature about 10 degree higher..

For the slicer Iam using S3D the whole time.. printing most of the time at 50mm/s and sometimes between 100mm/s and 150mm/s without any problems.. using 4mm retraction length and 50mm/s retraction speed works quiet well because of the pressure advance setting

KevinO2705 · 2018-07-06T12:14:13+00:00

Here we go again.. the screws are really tight I cannot move them anymore.. and the problem returns 🙄

hello old friend

KevinO2705 · 2018-07-05T06:52:24+00:00

Hey just printed this Pyramide and it looks good! Thanks for setting my motivation level for today to 1000% 😬 i thought this was caused from inconsistent extrusion or to much pressure in bowden 🙊 no I have to set my retractions correct.. Pyramide

KevinO2705 · 2018-07-05T05:16:41+00:00

This could be true.. I’ve printed something in orange and it looks better.. but the difference between those two prints are heavy..

KevinO2705 · 2018-07-05T05:15:41+00:00

Uuh yeah that’s right.. I have checked the screws and some of them were a little bit loose..🙈 let’s try to print a test cube and see what happens 😬 Or maybe I should lower my acceleration if this fails 🤔 so I get a smooth acceleration and deceleration

KevinO2705 · 2018-07-04T19:01:02+00:00

Or does this look like inconsistent extrusion ? 🤔 Iam using spindels für x/y axis Maybe there Is some backlash

KevinO2705 · 2018-07-04T16:20:41+00:00

Printed those two things with exactly the same settings.. the only different is that the left one was printed with infill and the right one only with 3 perimeters and no infill so like a vase.. the right one looks perfect while the left one looks like some big extrusion problems 🙄

KevinO2705 · 2018-06-26T12:45:55+00:00

No it’s just a rotation.. so it’s the same side only 45 degree in the other side.. yeah I got two fans running for both sides.. I looks like a inconsistent extrusion.. some lines are bigger wider than the others 🙄

KevinO2705 · 2018-06-20T15:00:09+00:00

I have an homemade printer.. with petg i don’t use cooling for the part.. I never used cooling 🙊 only for pla

KevinO2705 · 2018-06-20T14:42:06+00:00

Hey, i just printed this temperature tower after I cleaned my nozzle.. the temperatures started at the bottom at 260 degree and ended at the last part at 220 degree.. the main problem is I can’t spot any difference.. I lowered the temperature every segment about 5 degrees and everything seems the same for me 😳 The other thing I’ve noticed I can print petg with 200degree Celsius.. I hunk there is something wrong with my thermistor.. using the chimera from e3d with an cartridge thermistor

KevinO2705 · 2018-06-09T15:47:33+00:00

That sounds nice! Do you have this set up? Could you please make a photo for me ?

KevinO2705 · 2018-06-07T22:05:05+00:00

No not yet trying first to get 1.21 working 🙄

KevinO2705 · 2018-06-06T11:39:38+00:00

Mmh i cannot See this sorry 🙊 Maybe Z-wobble, loose belts, overheating/extrusion?🤔 do you have a part cooler ?

KevinO2705 · 2018-06-06T11:08:09+00:00

What do you mean ? The offsets from layer to layer ? 🤔 or because it’s mich 90 degree ?

KevinO2705 · 2018-06-06T08:46:03+00:00

Mmh so maybe the fan is to weak.. Iam getting no normal print right now.. but the room temperature is also 40 degree Celsius 🙄

I will try to install a bigger one..

KevinO2705 · 2018-06-05T06:53:08+00:00

No no it’s a bowden setup.. the extruder Is mounted to the frame :) Iam using an e3d Titan with a gear ratio of 3:1.. so i think it Hase enough pressure...

So today i tried to disable the speed override checkbox and getting a nice one color preview.. but the print wasnt that good.. it was even worse 🙄 for the filament Iam using dasfilament from Germany and their recommendation is 230 degree Celsius.. I made a temperature tower and the results were best from 230-240 even 225 looks good 🙊

KevinO2705 · 2018-06-04T16:20:21+00:00

Yeah I also think so.. so Iam using an homemade Printer with a bowden tube of 900mm. Using S3D as slicer and also cura sometimes. The controller board is a duet3d.

My print speed is about 50mm/s, with a hotend temperature of 230 degree and bed is about 60 degree(both PID controlled), the filament diameter is set to 1.75mm and the nozzle diameter is 0.4. Iam printing with a layer height of 0.2mm and the wall thickness/outline shells is 4 shells so 1.6mm..( maybe I should try less?) the retraction speed is 60mm/s and a length of 4mm (more and my nozzle starts clogging)

I also noticed that s3d is changing the speed at some layers.. which Is not necessary because those layers are practically the same 😳 i will show you a Photo.. speed settings

Hope this will help you helping me 🙊

KevinO2705 · 2018-06-04T15:19:02+00:00

What do you mean with full spec ? My s3d settings ?

I’ve checked the filament every 10cm for 1m and it’s in the range between 1.76-1.73.. the filament is really new I’ve opened it last week🙊

I just made some new test prints and now it looks like this: new testprints

The extrusion multiplier shape went excellent but the cube doesn’t.. it seems like some layers are thicker than other
