nice cura print
I'm really liking cura alot. Is there a way to scale an stl inside cura?

Bowden tube support
This has helped me get consistent filament flow. Very crude, but I'm going to draw and print something formal soon..

Nice print!
Your tube seems too long though. Since your Z rods are not that long anyway, have you though of cutting it a few inches?
Anyway, with a geared extruder, it may not matter much.

I was trying to keep the bend radius big to reduce friction. So you think I should cut it?

No don't cut it, if anything increase the length and keep the curve as slight as possible.

Right. This is why I mounted my geared extruder vertically in the first place. This way, there is only one u-shaped bend and not a spiral if the exit is towards either side. The only drawback is that I have to put it on the edge of the table because the filament entry point is from underneath.
Now that I have mounted my geared extruder permanently, I'm still satisfied with the print even if it's in the same direction as the original design. I'm running low on filament so I'm saving it for necessary stuff. I can't experiment yet if a geared extruder with entry point from the side and an upward exit point will work.

Hmmm... it looks like the 90 degree bend has been done on the ormerod extruder
Isn't such a tight curve dangerous for the filament? Most of them are quite flexible but PLA may be brittle, especially low quality PLA.

I'm not sure about the actual dimensions but it looks like the radius is big enough for it to slide smoothly. I can see that brittleness can be a problem with 3mm filament but I'm guessing not with 1.75mm.
I also noticed that the point where the drive gear is pinching the filament is already past the bend and is straight so I can see this working. Worth a try, don't you think?

I made an STL file for you MeIT, I have not printed it out so you can try it and report back if it is any good.
This has been made especially for you and although not a full 90 degrees is is close to what can be done without making the bend too sharp.

I like the tube in tube solution!
I'm wondering is PTFE 2mm ID x 6mm OD exists, then you just need one tube and 6mm fittings

Has anybody experienced parts getting out of proportion at the outer edges of the printing area?
I'm making something that requires almost full travel but the dimensions get bigger at the edges. Like an 8mm hole is 8.7.. I'm leaning towards the fishing line being too tight.

My steps are 99 on the x and 98 on the why. I have the stepper shaft spool adapters. I have printed a calibration cylinder 10 x 10 x 5 and I'm within .05 Should I print something bigger to dial it in?
