alittle lost....

[Orenfor]

ok, so i wanted to print something with ABS ( like i did before) and no matter what color i use i got more or less the same result ....
need help please to fix that out. ( all the ABS i used is from SeeNeCNC) hot end temp 230 - 238 ( i used few temp's wile trying to print) speed 30mmS
thanks

with the Brown ABS filament from SeeMeCnc I had never a good Print.
After hours of testing and about 500g ABS i put the filament in the trash can.
The brown Filament has blocked 2 Nozzles!!


With all others ABS and PLA is printing no problem and the results are perfect

i know that brown have problem. And I burn the nozzle after every print so it get clean and ready for new print but that not the issue. Every time I try to print with abs in the last day it getting like that no matter what the color... in pla it's print perfect.

Are you using a layer fan while printing in ABS? For PLA you want a layer fan, but ABS causes problems if it cools down too quickly.

[Orenfor]

yes, i do use it, i'll try without. until now it was working fine

While looking at your photo I noticed a couple things which while probably haven't caused this particular issue, but will likely cause issues for you at some point.

1 - Your tape appears to have been placed rather haphazardly. It appears to have a large gap that is within the printable space and towards the right side of the image it appears as though the tape has bubbles ( this might just be a lighting issue though ).

2 - I don't see any clips holding down the glass plate on top of your Onyx. The clips should be placed evenly around the build plate to ensure that the glass isn't sliding around.

I only mention these things because the devil is in the details with this technology. To get consistently good results you need to ensure you've reduced as many factors as possible before starting a print.

thanks all for helping ..
1. i'm not sure about the tape now because i already replace him
2. i do have clips. and you right , you can't see them on the picture
3. i solve the problem, the peak fan make the trouble ( i wounder why it's was on on my other ABS print and never done that problem)
4. now i have another issue that the part (in ABS) getting high at the edge, i guess only aluminium will solve that problem .

anyone ever try slice of silicone from semiconductor technology ? will it work and Dissolve the heat as well as aluminium ?

Are you saying that you turned off the PEEK fan? That's not a good idea, especially with ABS which melts at higher temperatures. If turning off the PEEK fan improved the print, then it's most likely you were just extruding at too low of a temperature initially. Or perhaps your PEEK fan is blowing air down on the heater/nozzle some how.

By "High at the edge" are you saying that the print is curling up? For me, I needed to do two things with a particular batch of ABS (White) -- I increased my bed temp to 100C and started using glue stick as the adhesive. I'm using a purple glue stick that dries white/clear (It's made by Avery, but I suspect it's the same as the Elmers varieties). FYI, it turns purple again when heated to 100C

about the bed temp, i never successes to rich 100 c , my best was 94 c
about the glue, i only have uhu glue and after about 5 hours of printing it didn't do the job anymore, i think the aluminum is the final way to do long printing in long run without have Curling up issue.
