About that print quality July 29, 2016 02:56PM |
Around 60mm/s print - 0.2 layer, PLA, stepper for size comparison,
Any thoughts how to make it better?
I have a print fan, belts are as tight as possible, all-steps calibrated, stuff..
What does the acceleration values and jerking do?

20mm Cube looks like this:
You can see the first layer has "saw edges"
For some reason my nozzle spits it out like that and it is constant from all the way to top.
The "saw edge" continues all the way to the top and in the same position. It is not random.
Also there is small banding running in 45 degrees angle through the print.
EDIT: Nozzle is 0.2mm

Prusa i3 Rework, as per [reprap.org]
I've changed the acceleration values and XY jerk and it seems to make a difference.
It runs more stable and will not block the nozzle that easily during print. Slight improvement on the print quality.
However, it still spits like that.

#define DEFAULT_ACCELERATION 1000 // X, Y, Z and E acceleration in mm/s^2 for printing moves #define DEFAULT_RETRACT_ACCELERATION 1000 // E acceleration in mm/s^2 for retracts #define DEFAULT_TRAVEL_ACCELERATION 1000 // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves // The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously) #define DEFAULT_XYJERK 5.0 // (mm/sec)
However, it still spits like that.

Almost rid of the curl.
Printed a PSU cover from Toolson. ( [www.thingiverse.com] ) 3:50 printing time and this was the result.
0.3 layer, Those two square holes came out really nice.
Time to declare a victory and move on?

I don't know about the layers, but Infill looks nice when printing. Maybe i should make the perimeters, say 10% fatter?
IIRC, those perimeters are printed 60mm/s inner and 40mm/s outer. Cooling fan is always on, atleast 35%
I'm beginning to think i have some kind of physical damage in the nozzle tip. (combined with ringing from the backlash of mechanical parts)
This damage would make the plastic juice flow more on some direction than the other.
To eBays! And a new nozzle.

Hang on, did you say you've got a .2mm nozzle, and you're printing with .2 or .3mm layer height? That's an issue. layer height should be less than 80% of the nozzle diameter at maximum.
The following was printed on my Folger, with the stock .4mm extruder nozzle, at .1mm layer height:
Notice how tight the layers are, none of those gaps. That's what you're shooting for. Lil red kitty was made on my Folger, took just under an hour.
