  1. wow that's great - those images are really helping thanks! i'm going to run some experiments!
  2. hello. so how does one go about creating your own supports within a 3d modeling software? there's lots of different ways you could do it i suppose... little boxes, concave platform that would support a sphere... when you model, are you supposed to have a gap between the top/bottom of the box or concave platform in the case of a sphere? if so how much of a gap? a gap larger than 1 layer height? or somewhere in between? do you round off or bevel the top of a box to a point, single vertex then place that x distance from the surface it is supporting? any tips? thanks!
  3. here's the final product. you can see some weirdness on the roof on the right box, i'm assuming those are seams, a blob and the top looks a little rougher in the middle than the ends. the bottom and roof surface look pretty good though. funny how the reflection changes on the big flat roof where the hvac and roof access boxes are, it's like a darker color. i wonder if that's due to slight temperature fluctuations or maybe inconsistency in the filament? i'll be doing some testing today for sure! on little test cubes and such!
  4. thanks! ive read a little about pei, am i mistake or is it some type of flexible very thin overlay like a sticker? id like to avoid stixk on type things especially tape. the borosilicate glass seems lukje a great idea, id still have to have some type of tacky substance on it im guessing. the main thing is that it is flat haha no tinfoil! ill get around to orderinf one but will stick with what i have for now... which mean next week ill probably order so mething. my hairspray doesnt seem that tacky when i touch it, but so far so good. ill see. maybe that pei isnt what i think it
  5. yeah i think it makes a lot sense to start doing more calibration prints like you say start tuning. i am getting some of the basics down now in terms of machine setup anf some basics in the prgram settings. one thing i was just reading about on printed solid.com blog was corner quality and ringing. i am seeing a lot of rimging. i know why it happens, just have to tackle the 30 different things that can cause it haha. but yeah i should focus on temp, retractions, speed etc kind of low hanging fruit with test cubes and stuff. ps print of the roof finished, looks pretty good! i h
  6. yep architecture. i got this as a hobby for myself and set it up at work because well, my hobby(s) are my work ha! if it works to do for clients then it's just a bonus! yeah i read about test prints for extrusion tests, temperature tests, all in one. little pyramids as i recall. i will have to look those up again or make my own. 4 tall thin boxes shaped like pyramids. it looks like i messed with some settings in my custom profile i saved with the cura project for the 4 walls and base, but retraction distance is 3mm (i think that was the default of 5), all of the retraction spe
  7. yeah, that seems to be catching me more and more - i keep looking at software settings instead of bed leveling or mechanical issues with the printer etc... i'm quickly learning to master that! do test prints ha instead of testing on a big complicated print! which i'm pretty amazed at how the last one turned out given i did nothing but hit print and try z-hop. ha! i'll attach. right now you've all see pics of the "roof" i'm printing separately, i'll attach the base. it's bad, i know stringy like you can't believe, some details didn't print - the window lines, but most did so i'm happy enou
  8. thanks everyone. so that goofy looking patterned layer print failed. lots of stringy gooey goodness. i was away from it for several hours, 4 maybe. ugh. i whipped off that mirror, got a new mirror and put it on the bed. leveled and it was great leveling it until i heated up the hotend and bed. then, like the first mirror, it was cupped in the center. when cold, it was perfect! so, this AM i went and got tinfoil and stacked up several layers of 6x6" or 5x4" squares of it in the middle of the bed under the mirror. it was back to "perfect". this time thoug, i'm not using glue stick. i spra
  9. cool. ok for color got it, makes sense but i thought there was some special case with white the way i've read about it ha. learning quirks for different things in printing! consistency will be the key in terms of filament i'll bet. we'll see how the verbatim goes. one last quick question, does cura raise the z-axis depending on the height of the first layer and subsequent layers? it must huh otherwise the nozzle would be digging into the pla it's laying down. so it can compensate for the whole build - it might be .4mm thick on the first layer but then it says i can skip 3 laye
  10. doh! so thats what that setting is right under layer height. i was thinking it just built up the .12mm layer until it got to the height i entered. so if i entered .24mm initial, i thought it would lay down 2 .12mm layers. it actually puts down 1 layer that is .24mm? thanks
  11. thats a great idea! i didnt know i could do that really, change the first layer height to be thick. my current layer setting is .12. pictured is silver hatchbox 1.75mm pla. why do i hear that lately, that white is no good for anything? ha. i just ordered some white verbatim pla purely on company reputation and affiliation with mitsubishi chemical. im willing to bet it is top notch quality and consistency. some utubes i have seen bare that out except for thier first gen stuff. edit - the 47hr print was kicked off based on a previous print that looked fairly good so no r
  12. attached is a pic of the finished 1st layer and it's laying down the 2nd layer, which despite this pic, looks a bit smoother. there will be several layers. so maybe it just evens out. this is only about a 7hr print. it's basically a thin box with 2 other smaller but taller boxes on top of it, one on front half and one on back half.
  13. hi. i just got done with a 47hr print which has a similar 1st layer to the one i'm showing here. the previous model was pretty stringy, the 1st layer is somewhat uneven feeling on the bottom, but other than that it's printed fairly well for 47hrs! so this is another component of the 47hr print, the attached picture is of the first layer. it's about 5in x 5in square. i have glue stick on the bed. the glue stick is probably just too uneven. bed temp 60 nozzle temp 200. i tried changing the nozzle temp to 195, the many of the lines did not connect! so i went back up to
  14. so i've been playing with a small building - basically the shape of a box with some ins & outs where windows would be, but nothing really detailed as i'm doing this for comparisons. 1. i modeled the building with the 4 wallls, but ZERO thickness to the walls. (i'll call this "solid walls") in cura i turned off top/bottom - set top/bottom thickness to 0.0mm i turned off infill i set my wall thickness to a multiple of my nozzle dia, 4.0mm i think this is more or less vase mode? 2. i modeled the building with 5mm thick walls. (i'll call this "hol
  15. kman and gigi thanks for replies, sorry for late response. great points! kman yeah i started figuring that is the case, just like rendering an animation, trade between time and detail/quality. nice to have confirmation. sometimes i can be real picky! i did notice my cr10s came with a different and smaller nozzle! .2mm i think. gigi thank you, i will check put your model and now that ypu say that, I will play with the model of a building i am printing right now. so does the preview always show accurately? for example i have a building with window frame
