[Gaps around concentric / round holes]

Hi everyone,

 

Using Cura 4.0 now, however I noticed this on all versions so far.

 

All the vertical holes in my models are printed with gaps around them. I don't have coasting activated, and the preview inside Cura shows properly filled extruder paths.

 

My printer is a Migbot Prusa i3(acrylic frame), mk8 extruder and a 0.4mm nozzle.

 

Should I try another printer "flavor" inside the settings? Maybe it's a gcode problem?

 

Thanks in advance!

[Cura 2.4beta - Center bed (set x/y offsets)]

Thanks, the second option worked well! Actually, I found it earlier in this topic: https://ultimaker.com/en/community/19190-xy-start-print-offset-setting-in-cura

And it works! Strange thing, in Cura 2.4 there are different offsets, for example, in Cura 2.6.1 that I'm using now I noticed the print area is higher mostly (top of the bed, Y axis).

Anyway, the correction worked for me, I'm using this GCode, with only the bold line added.

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

G1 Z15.0 F9000 ;move the platform down 15mm

G92 E0 ;zero the extruded length

G92 X5 Y18 Z15 ;Set this position as the new X/Y zero

G1 F200 E3 ;extrude 4mm of feed stock

G92 E0 ;zero the extruded length again

G1 F9000

M117 Just a sec, man... geez...

[Cura 2.4beta - Center bed (set x/y offsets)]

Hi, sorry for the late reply. I didn't receive any reply notification.

The printer is a Prusa i3 (Acrylic frame), with a 220x220 aluminum bed.

Hi guys,

How can I center the print on the bed, and be sure the nozzle won't go over the edge? Right now the parts that are close to the right edge (X axis) risk being printed outside the bed.

Or more simply put, I want to tell the printer to move its printing area 1cm to the left.

Thanks in advance!

[Thin wall settings?]

Hi guys,

Sorry for resurrecting this thread but I'm having the exact problem in Cura 2.3.0. Is there a setting I should change to actually get completely filled thin walls?

I attached a screenshot(although the infill is at 25% in the pic, the same thing happens at 100%)

Thanks in advance,

B
