@surfmagic That can cause your layer shifts. It sometimes happens with certain materials if the overhang is too big or there are too many perimeters. Its a sign of uneven cooling. If you have the fan on try it with the fan off if the fan is already off the only things that help then is either up the chamber/ ambient temp if you can or use a different material or reduce the amount of material by reducing infill and perimters which will give you a weaker part. Or go to a differnet brand or material
@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.

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
There is not a feature for that yet, but the next update will always to a retraction (and z lift if available) when traveling over top layers. This can dramatically improve top layers.
@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)
MatterControl PRO has a Gear generator now. You can specify height, tooth count, pitch, ID, pressure angle, and clearances. You can also create a rack.
@lhawes To dial in extrusion multiplier I use this
https://grabcad.com/library/frc1989-filament-dial-in-1
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.
