  1. @geert_2 - Fortunately I have a plexiglass door I made a while back, but the top is still open. I suspect a lot of heat escaped via the top... the while things about hot air rising and all of that πŸ™‚ Yes, winter indeed. To make matters worse, we have a lot of rain in winter (in the Western Cape), so it can be really cold at times.
  2. Thank you for the heads-up πŸ™‚ I also used the drawers for resistors, small ICs and Capacitors.
  3. Hi @UlrichC-DE - I do indeed have the 0.6mm and 0.8mm nozzles, only tried to use them once, but found the layer lines to be 'too visible' for most clients πŸ™‚ I have no idea that 60mm is too fast of 0.4mm nozzle? I found some math in the forum on how to calculate speeds, and it seemed well within the capabilities of the UM2+. I will change these tomorrow and see how it goes. Looking to upgrade to UM3 or S3 soon, so maybe it will improve things a bit πŸ™‚
  4. Great thanks! ugh... 50mm/s?? these enclosures will take all day to print πŸ˜„ ps: Did you try those drawers? I will be printing more this week. Have some components on the way, need to make place to keep them πŸ™‚
  5. Thanks @Smithy - I am printing the PLA at 210C, 100% flow and 60mm/s. I will try printing at 200C and see how it goes, thanks. The sound is not too much of a problem, but I can see the knock-on affect on the outer walls as well. Not the end of the world, but would still prefer to 'fix' if πŸ™‚
  6. @Smithy - Ok, so I built a thermometer posting readings to my phone so I can monitor the temperature. Without covering it with "something" it drops well below 15C inside the chamber. I covered it loosely with a black bag and temperature is hovering around 25C-26C. Prints are working. I do have one nagging problem I have been facing since I can remember. When printing larger parts like the enclosure I am currently printing, everything goes smoothly until I am Β±50% up the side walls. I then start hearing these noises and it seems to be occurring when the nozzle is
  7. @Smithy & @Torgeir - It does look good indeed. I will place an order today, will probably switch the CPE for ASA then, even though the video review on their CPE was very positive. With regards to my layer separation problem on both CPE and PLA the past two days... I think I might have confirmation on the problem... see image attached. Our min temperature today was 3C and max during the day was 6C πŸ₯Ά As I need to print this weekend, I will have to enclose the printer. Will leave the thermometer I made inside to monitor temperatures. Regards, Friedl
  8. HI @Torgeir - Wow thank you, I will most certainly try this. I printed ` couple of time today with PLA and CPE but experienced more layer separation πŸ˜• I cannot believe I have not done this sooner, but eventually grabbed some components and put together a quick thermometer to measure the ambient temperature around the printer. Outside of the printer (later in the day) I measure Β±16C. It is very possible then that the temperature was lower earlier during my prints. I will conform this tomorrow. If your solution works for me as well, I will probably design a cover t
  9. Hi @Smithy - I am looking at Fillamentum range as we 'speak'. They seem to have a large range of aesthetically pleasing filaments in 2.85mm and different materials (ASA, ABS, CPE, PLA). I am getting to the "I HATE CPE" point, quite quickly I might add. If I get it the layers to stick, the details are terrible. If I try to counter that, I get layer separation. Tough PLA seems like a good choice and I have heard good things about it. I do however need some sort of chemical resistance (against Sulphuric acid vapours in particular) so I just went straight for CPE. A
  10. @Dim3nsioneer & @UlrichC-DE - Thank you for the tips. I saw the black bag on YouTube videos πŸ™‚ Was getting desperate when even PLA prints started to delaminate. Seems the cause then is the ambient temperature as it is below 15C indeed. I will have to heat up the room I suppose. Regards, Friedl.
  11. @Smithy- They are printed and they are great indeed. By far the better ones I have found so far. I scaled them to 50% as they are for small components, I have attached them for your convenience πŸ™‚ Maybve scale the drawer 1% more, but depends on your printer I suppose. Regards, Friedl.

  12. Hi @Smithy & @Torgeir - I have tried all three combing settings, turning it drastically increased the print time of this particular part from 5.5hours to almost 8 hours. I am printing again today, will let you know how it goes. Thank you @Smithy really appreciate the help! @Torgeir It is a pleasure, I really hope they work for you too. I am hoping to get cleaner prints today, I really cannot see how people classify this as engineering filament if these are the results. I am getting much more accurate prints from PLA at this stage πŸ˜„ I do need something stronge
  13. Hi - Just thought I'd give an update as I have some moderate success printing with CPE πŸ™‚ I changed the settings as follow: Bed Temp: 75C Print Temp: 260C Speed: 45mm/s Fan Speed: First 5 layers @ 35% and then 65% thereafter Enclosure: Close front Printer: UM2+ Bed Adhesion: Skirt with Magigoo FLEX I am not sure whether it was the change to Magigoo FLEX or the combination of a slight Temp bump and reduced fan speed or maybe even all three. It was quite a large part, about 12 hours print. I have to say, the part
  14. Hi - I have been printing successfully (using PLA, CPE, TPU & TPE) for the past 8 months or so and have never experienced delimitation before, let alone while printing with PLA. I have had warping of CPE parts (pulling off the bed) but PLA has been straight forward a trouble free... so far. I read through a couple of posts, the seem quite dated so it seems everyone else has figure this out but me πŸ™‚ It is the first winter since owning the UM2+, so I am trying to figure out whether ambient temperature could be playing a part. It has been quite cold lately (7-10C).
  15. Hi - Ok, I managed to "solve" CPE warping off the bed by reducing the model size... kind of besides the point but at least it is a start. I also use Magigoo Flex as apposed to the standard one. This now presented a new problem. Even though the print seems acceptable, it is about as watertight a your average garden sprinkler πŸ™ˆ My first guess would be that the layers aren't fusing properly. I am using the standard Cura settings at this stage. The bed as level as you can get it, the same print with PLA hold water perfectly, even under some pressure. I will
