  1. Thank you my good man! I suppose that's why I don't recall having these issues previously.... I must not have been using concentric for the bottom. I'll keep on printing! Happy holidays.
  2. Thanks smartavionics! where do you add the skin? the model/cad program? or within cura? I'm not trying to have a small hole within the larger hole by the way. just trying to have a recessed hole with a 'ceiling'. I'm going to put rubber feet on the bottom of this part so it doesn't slide around and a flat surface here would help with the rubber feet to adhere. Support the best avenue then?
  3. Hello everyone, I'm trying to figure out what settings might be most efficient for these types of overhangs. If you look at the images I've attached, you can see that the extruder starts to fill the 'bottom' of the circles in mid air. is there a setting that could possibly connect this with the shell instead of extruding in mid air to start the 'bottoms' (or tops depending on how you look at it) of these circular recesses? I've printed the part and since it starts like this the filament just ends up garbled in the hole. I'd like more precision of course. Support is one method, of course. This is only about 8 mm bridge which I feel like I should be able to get away with if it's connected to the shell. Thoughts? Thanks for reading and for your input, in advance. Happy Holidays y'all!

  4. Perhaps this has been discussed before but I have not found answer to my specific question. It seems this experimental option is not available anymore. I am trying to minimize material (infil) for a very basic design (cone with flat bottom) and don't want to use use infill on those areas which do not need it (support). How to I add support to the inside of my object without using infill? is there a way currently? Does other slicer software allow this?
  5. Thanks smartavionics. I had a feeling it wasn't anything I did because all I did was update versions a short while ago. I see all your versions and thanks for the offer. Can you tell me a bit more about them? I saw a readme file and it seems like they may be for Linux? I use Windows... I also have another question if I may, when my prints start, sometimes the filament is not available right when the nozzle starts extruding. Basically, after the nozzle heats fully and the Hot end is on its way to reference home position and then move to the beginning of the print, during this time some filament is extruding simply due to heat. There is a small attempt at clearing the nozzle I can tell the code has this because when I print at lower temps (170-180 or so) it clears the nozzle at one corner of build plate before continuing on to the start of the print. When I print at higher temps and faster speeds (220c and around 80mm/s with a .6nozzle and .2-.3 layer height, various PLA's) it leaks filament before the start of print. TLDR: I've never written commands into gcode or 3d printer or whatever but is there a way to "prime" the extruder more? Maybe have it clear the nozzle for a bit longer time near end of build plate?
  6. Hello all, When I test run a bed level there is spacing that normally was not there when I ran testing before.... what has changed? It eventually goes back and fills in the missing space but why does it do it in this order now where before it would just run fro the middle all the way out without the spacing?
  7. Thanks gr5. Honestly, I'm not even worried about flow at all. I've found a happy medium and it works well. What I'm trying to dial in is the fastest prints but still with good quality and adhesion. When I set initial print speed to 25 I don't feel like it's actually setting it to 25when I generate the gcode file, first layer seems fast still much too fast. Example: in printing at 80mm/s and initial is set to 25 but it still seems like it's printing at 80. Are there any settings that would override initial layer print speed?
  8. Hello there, I'm wondering if I'm doing something wrong when I change print settings within a profile. lets say I want to run some tests and see how much increasing 'Initial Layer Flow' (ILF) has an effect on my prints. So I select a profile and export a gcode file while ILF is set to 100%. then I change the ILF to 110% and save another gcode file. when I save this next gcode file, I don't change the profile, mind you, I'm not saving the profile with new ILF setting or anything just literally upping the value of ILF to 110, processing and then saving. My question is, will this result in gcode that is includes the higher ILF value? or do I need to save the profile with the new value (110%) and then process and save? I'm asking because I feel like when I make certain changes, say to 'initial layer flow, or to various speed parameters, I feel like sometimes they are executed in the gcode and sometimes they are not. For instance, I have been playing with initial layer print speed. I want to make 100% certain that the 1st layer adheres, of course, and so I'm keeping that low but at times when I'm monitoring in the beginning of a print, it seems like it's not printing the initial layer slowly at all, almost seems like it's as fast as the print speed I have set for the rest of the print. I have my initial layer print speed set to 25mm/s because I have some sharp angles to some of the lines in my model and I want to make sure that it lays them flat and doesn't move to fast while printing which I've seen turns out like not such a sharp corner and tends to want to lift on the first layer sometimes. Same goes for Initial Layer Flow, I set it high on the first layer to adhere well and it usually works great. I've been playing with setting it lower and it worked out not as well, so I went back to the higher value but it does not seem like it's flowing like it did when I initially had it set higher. Any input will be much appreciated! Thanks, Erik
