@surfmagic said in Bad prints in pulse XE with lots of support structure.:
Hi I have no warping on my other parts that have printed good previously with nylonX. They measure exactly as the computer model up and down. I had bad warping on nylon but this is nlyon X. I have a heated enclosure at 40C. The parts that print good fit exactly into other parts. I am really blown away by the perfect fits of my parts.Extremly happy with the good prints, better than expected. I just do not know why I am starting to get these layer off almost every other print which I didn't get before. But maybe its the models. I am washing the bed every time and re-calibrating the bed every time also. well, I will keep trying. Thanks for your effort to help me!
I was getting the same problem. I ended up getting it narrowed down to- incorrect z offset / initial layer too low- causing the sides of each line to spiil over and eventually build up
With a bit of warping from fan settings or lack thereof that the nozzle would eventually hit and miss a step.
Also z hop plus getting a more desired initial layer. Couldve been the loose heaterblock it came with. Or z axis out of sync , idk. All of them ? None of them? Your guess is as good as mine. Too bad these "prusa clones" would only qualify to as prusa's second cousin. If the cousin was mentally retarded instead of smart and capable like an actual prusa.
Boy am i salty
450 dollar azteeg x5 gt when they are less than 150, dont start comparing the rest of the parts , or youll be salty af too.
My pulse is destined to be scrapped toward a voron switchfire . Not because im some goober with no brain. The parts are coming out more often than not pretty well. They fit, and are functional- mil spec. But i get closer to the edge everytime i inspect further
@thwclw Thanks I went for the visuals too right now its I think about 4 kg of HIPS about 20 608 bearings and almost 100 nuts and bolts. if you Want your own all the files are here
you wont print it on a pulse though. This one needs a 300x300 bed or larger as the big ring holder are 286mm end to end. I used HIPS cause I pick it up for less than $10/kg and so its less of a problem if you have to reprint something cause it doesnt fit then if you use Nylon
Now this is one you might be able to print on a pulse
The Holder is ABS the gears and Rim Nylon 910 and the tire TPU.
All was printed on a Chiron
Here's a study claiming effective EMI shielding with "Graphene" filled filaments - I didn't delve into it, just stumbled across it and then saw your post:
@thwclw Thanks Rn working on making the electronics It will get a current controlled DUI motor driver - actually 3 controlled by and arduino. We will see how much this thing will be able to put out input will be 3x 4 in/lb at 4100 rpm
@bni I would do 2 things
1.) Make an enclosure for the Ender 5 this is the first of a series of videos on that
2.) 240 is going to be too low for nylon so I would upgrade to an all metal hotend - He covers that too in the parts following the one mentioned above.
ABS ASA I print on the chiron with ultrabase (coated glass) at 105 C bed and 260 nozzle with enclosure and Nylon too at 260-280 nozzle and 80-90 bed - again with enclosure. And I run the materials well dried directly from my print dry (converted food dehydrator)
@lhawes To dial in extrusion multiplier I use this
and Then measure with a caliper. The walls are 1, 1.25, 1.5, 2, 3mm respectively it also can show some slicing problems like if there are gaps and/or lets say the 1 mm is dead on but the 2mm one is way off. It has enabled us to tune the printers to a point where we can print stuff in HIPS (which we pick up for $10 or less / kg and get all the problems worked out and then print it in Taulman 910 and expect dimensional accuracy to the point. So I can print a planetary in a mix of HIPS. ABS, PETG and Nylon and expect it to mesh - not that I wanted to do that as a practical thing
@macks1819 So if its not listed its pretty easy to figure out. ABS has a density of 1.04g/cm3 So 750g are 750/1.04 = 721 cm3 so the cross section of the filament is circular with a diameter of 1.75 that is a radius of .875mm so applying r2*PI - about 2.4 mm3/mm of filament or 0.0024 cm3 per mm 1m = 1000mm so 1m = 2.4 cm3 of filament 721/2.4 = aprox. 300 meters on a 750 g 1.75mm spool or about 400m on a 1kg spool. Now you can do the math for a 2.85mm or for PLA where the density is about 1.27g/cm3 etc.
As you are paying by weight you are getting about 25% more prints out of ABS then you get out of PLA.
