  1. Hello guys, I am printing with a 0.8 AA core and I find that the top layers are not coming out as nicely. There is quite a bit of "lifted" plastic or markings of the start and end points.

    the smaller the part, the more this can be seen. 

     

    I am wondering if there a setting in CURA and will allow me to mitigate this.  

    Could it be a mixture of retraction (add more - currently at 5mm) and top/bottom layer speed? 

     

    example below part size is 1" x 1.75"

  2. I decided to print ABS (UM brand) with my S5+Air Manager for the first time and a 0.8mm AA core - Long story short, I was unable to get the parts to come off.

    I woke up to a cooled off print surface. When the prints finally came off, despite being careful, they took large layers of glass with them.

     

    I have been using Magigoo PA for everything and I used it with the ABS thinking that I would need all the help I can get. I think that doing that in combination with the printing temps (more on that ) contributed to the issue. The temperatures are based on the NFC profile and the air manager was set to keep the print volume at 35C.

     

    These print had the first layer spread out creating an elephants foot effect.

    needless to say, I tried to make other smaller prints with PVA this time and still had the elephants foot. However they were easier to remove.

     

    I have been tweaking settings and have been able to get rid of the elephants foot just by decreasing the build plate temp to 70C. I train of thought is that if I have an enclosure, the trapped hot air (temp being contained) will help prevent warping and hence I do not need such hot build plate. 

     

    I will post another screenshot of the tweaked settings for your guys info on what seems to be working at the moment.

  3. Tell me us more about this plugin @Smithy.

    This thread came at a good time. I usually let my prints cool off and they pop off even when I use magigoo. However I completely damaged one of my glass plates last night printing ABS.  Does not matter the size of the part the glass was chipped and missing large chunks. 

     

    I did let the part and glass cool down overnight. Apparently that is a no no with ABS. But honestly at times I am not around when the printer is doing its work and sometimes it finishes early in the morning while I am still sleeping.

     

    With all this said I was to also experiment with a flex plate or some sort. too bad they (ultimaker) decided to not make the alum, plate. Maybe I can make one and just mill it flat.

     

    has anyone tired garolite?

    Something i found out recently is that you can change the build chamber temp in cura (max 50°C).  Which helps with ABS alot.

     

    Yes, keep things warm and turns off the hood fan. 

     

    I was expecting that it would allow the chamber for get warmer.. (maybe just disconnect the cable) 

     

    I am using magigoo* and cant get nylonx to stick with a skirt. Maybe nylonx just need a brim. Which btw, with a bring it printer w no warping and the chamber set to 50c.
