Is my printer working well?

Hey,

I just wanted people to take a look at my prints and tell me if this is on par with what to expect for low and high quality (I'll specify which photo is which)

I have some concerns with bridging and fill, and I spent some time in the first week of using this, troubleshooting (all nighters). Before I press on I just want some feed back from people who CURRENTLY own a robo3d to tell me how this compares to the types of prints they have.

First and foremost, is this normal? When printing the prep outline it's set to print two lines. But every time it looks like it's an inch or so behind at the starting point. Look at the top right corner. Should the start and finish actually meet, or is the gap on the first line normal?



I'm having bridging issues and some fill issues. However despite that some of my high quality prints looks very good. Not sure what to expect to be considered a "great" print.

Here's an extreme bridge attempt I know. But even quarter inch bridges are failing hard, as shown in some photos below. Basically I'm printing with 100% infill because the bridging is so bad.



Regarding fill, this circle calibration seems to print very nicely on high quality, but still the top layer fill has some missing spots.



This low quality print, at the edges it's not aligned properly when it wraps around the end. So there's too much on one side (shown here) and a too little on the other side.



This one turned out OK at low until it got towards the small parts at the top. I dont think it's cooling enough, staying too soft.



From left to right it's low, medium, high quality. The HQ one turned out much better but it had top layer fill/bridge issues, shown in 2nd photo. IMO it has issues right after wrapping corners, (shown below and two up).




The whistle surprised me how good it looked on high, for the spot where it printed well like the logo. However the ball wont stick, I'm wondering if the whole piece isn't cooling enough somehow, since the ball time and again will get knocked over by the print head since it's not adhering at its base well.

 

They look good. Just need to graduate to a new filament

 

You might need to calibrate your extrusion rate. Is that with the stock hotend? The whistle looks damn nice. To try fix the ball getting knocked over make sure your configured to do a z lift on retraction, 0.4mm should do the trick.

Those skirt loops are completely normal. The hot end is oozing out some plastic while it is waiting to get itself and the bed to temperature. This causes a delay when the skirt first starts until the filament feed catches up. This is one of the reasons for specifying skirt loops.

That bridging is pretty bad. My guess is you have a problem with a combination of poor auto cooling settings, bridging speed, and perhaps the filament and filament temp.

All the curled up cube edges and melted spires are due to auto cooling settings.
