Anyone have any advice.. with this? Is this the settings? The slicer? The Software?..
For comparison, When watching a replicator 2 do its infill an an object I built, the machine just flows and does a consistent job.
On the robox, the speed of the print head and path it takes to make infill is blazingly fast, but sloppy and erratic. A grid portion of infill looks ok a recognizable, but there are like dozens of start and stop points the print head is attempting. Almost like little blobs its trying to place every where in little corners. And th stepper motors go crazy fast hitting all these start and stop points. It just looks rediculous. As if that is necessary.
Another thing I constantly notice is the print head will splooge out more material than is needed at the start and stop points of a layer resulting in a puddled up nub sticking out the sides of places. (I’ve gone and calibrated the nozzle opening thing before, I dont think thats the issue.. or is it,… ) To me it almost feels like a software thing the robox should be compensating for.
Robox does well enough for me on simple big shapes, but when things are delicate and small,,, things become blobby and messy because the machine just behaves like its over eager to finish fast and throw plastic around.
thanks.
Compared to the Replicator 2 you should slow down to about half the speed on the Robox. The Robox is able to use pretty high travel speeds due to the light weight print head, but for actual printing you should stay around 30 mm/s to get consistent results at a high reliability.
Which version of Automaker and which of the print heads do you use?
Always the latest version. I am printing with default “low” quality settings. I dont touch the real time speed adjusters.
Maybe I create a custom profile with standard settings, but .3 mm layer height.
When the slicer sees a small space between perimeters it will add fill to that area according to the rules it is following.
Every model is different, the perimeters are calculated and then the remaining space is “filled”, to reduce fill in narrow walls the best and easiest method is to add more perimeters. Now the same space will have a solid perimeter line instead of fill. BUT if the space is too small for a perimeter to fit then it may be left empty.
Try to make walls which are multiples of the Extrusion Width or adjust this setting to match your wall thickness. Curved walls add complication as they are not curves but are lots of faceted lines simulating a curve so wall thickness cannot be consistent.
