an interesting test. I created this model: It is 1mm high with holes from 1mm to 9mm sized per the formula.

@Supermec - As OP, IMHO, all of the relies are good information. I think that you may be over reacting to the Doc's statement. The key would be the part that starts "To me.....", which is not unlike my drills & sandpaper take on it. Unfortunately, a screw required drastic measures like modifying the design. Drills and sandpaper don't work. I took a SWAG at it before your reply and it could beby ruggb - Printing
And they say that additive manufacturing saves material.................. By the time one prints enough test prints to get this right, it would be better to have a lot of drills and sandpaper.by ruggb - Printing
Thx hedgehog, I will experiment with that. Is that written someplace that may give more info. It would seem like one would have to take into consideration temp, layer height, first layer height, squash level, etc. I have previously found that a horiz hole comes out about a layer height smaller than design. My object was not a plain hole, it was a very large (40mm) screw and nut. So making the cby ruggb - Printing
Thx Doc no problem with ovals. X&Y are mechanical things based on 6400 steps/rev on the steppers (200 x 32 microstepping). It is a CoreXY, so by design it is pretty much square extruder calibrated about as well as I can measuring 400mm - but then it wasn't hot. I may need to try that again. Problem is, it probably varies with temp and layer height. Any info RE that? It wasn't my model. I havby ruggb - Printing
I have a downloaded file that has an eyepiece with a screw thread for focusing and a receiver for it. Looking at the file, it has about 0.14mm clearance between the part screw faces. My first attempt at printing it was a disaster. With a lot of sanding and Dremel work, it still won't screw together. So the question is - what is the trick to printing this so it will fit together.

Yeah, thx Dave. I did try but even a zip file was too big. I thought I uploaded it to gdrive and posted the link, but I guess that was something else. ANYWAY, I did finally find a problem in the stl file even though it checked out and was manifold. That solved it.by ruggb - Slic3r
I have a model that is a frame with 2 holes in it. It checks out fine in Sketchup = manifold. I import into Repetier and slice it using support with contact distance set at 0 and end up with support and a cover over one of the holes. Both holes are symmetrical and in the same plane. If contact Z distance is set at 0.2 it is fine. I can't imagine that this is suppose to happen so I am assuming itby ruggb - Slic3r

I have 2 prints of similar objects. 1 has default settings for accel.- 1 has accel of 6000. The 1 with 6000 shows a more pronounced overshoot on the corner where Slic3r starts. Actually, it isn't overshoot b/c the head was moving toward the edge (leading edge) - there is a VERY slight trace of actual overshoot on the other 3 corner trailing edges. U can see the top 2mm doesn't show the overshooby ruggb - Slic3r
I am using Sketchup. I normally set the circle segments to 120 (default = 24). For a 100mm dia circle that would yield a segment of 2.62mm, or 0.26mm for 10mm. Default yields 13mm segments.by ruggb - Slic3r
I'm not an expert - I don't see any settings in Slic3r that would do that. I am using Repetier Host w/Slic3r. It may be a bad install or it may be some strange interaction with matter control (which I have no familiarity with). r u using ver 1.2.9?by ruggb - Slic3r

well the above seems to work it is setting the origin at the 0,0 of the hotbed and setting the top rt limit to the top rt corner of the hotbed. it results in the model being sliced dead center of the hotbed if i do not manually chg it. of course, this is also dead center of the full bed so i can't say which Slic3r is setting it at. I guess I could chg the upper limit and see if it moves it. OK -by ruggb - General
thx Srek --- but that wasn't the question and my bed is not unevenly heated - I just have a smaller build plate when using the hotbed. there is a Bed Shape option in the Slic3r config. when i am using the hotbed i tell Slic3r with the Bed Shape entries so that it slices it on the hotbed. I could ignore that for 2 reasons: 1. My hotbed is in the center of the full bed and Slic3r always defaultby ruggb - General
My printer's bed is 335x305 BUT I have a small hotbed 200x200 with origin located at 50, 70. My question is, should I set the BED SHAPE in PRINTER SETTINGS to: size: x:335 y: 305 origin x: 50 y: 70 or size: x:200 y: 200 origin x: 50 y: 70 Obviously, when I am using the full bed I set it to size: x:335 y: 305 origin x: 0 y: 0by ruggb - General
I built Carl's CBOT on Openbuilds and modified it to make it narrower but I kept a 12x12 platform. I also changed the platform to 3 screws instead of his cantilever design. His std builds list 8x8, 12x8, 12X12. So if u r good with a CAD program, it should be a piece of cake. I guess if u r not, u could try scaling what he has to 400x200.by ruggb - CoreXY Machines
this is my model from Sketchup. Real life looks the same. The adj bar is made from scrap pieces so it doesn't look as pretty as the model. The pulley wrap is not as much as Adam's design but it works and I have a heavy 5/8" 15x16 MDF build platform. The Z axis also moves a lot faster than the default Marlin settings.

Yes, that is actually Carl's design with the same mod to the platform. Mine is a little simpler with the belt. That one also has a direct drive extruder. Carl's & mine use a Bowden.by ruggb - CoreXY Machines
I built this one. It was love at first sight, mostly because of the integrated belts and the lack of smooth rods. I did modify the platform to use 3 screws and 1 stepper instead of the cantilevered design Carl did. It can be easily scaled to the size u want. Mine is 12"x12"x12" or 305x305x305mm (z ~= 290mm actually) dual hotends. I modeled it first so I could reduce the width by about 2 inches.by ruggb - CoreXY Machines

Do I want to tax my brain more??? good answers-- the basic problem is I have not been able to create a bridge surface. since i can see light around this surface I figure it was the slic3r. I massaged the model a little and it no longer shows a gap. I have no idea what fixed it. i still couldn't create the bridge surface.
