My Davini 3D printer from XYZ Printing is back in action printing all kinds of products. I ran a bunch of vertical blind valence clips and noticed the print bed was off a little. I adjusted the bed while the print was going and you can see in the picture below the filament plastic is laid down almost perfect with a slight flatness but rounded on top. And its sticking to the heated bed without lifting. This indicates the perfect bed to nozzle clearance based on my experience.
Also note though that the first print at the front of the picture has some out of place discolored plastic in its first layer. Typically the printer runs a test strip on the side to start the plastic flowing and then starts the print. But I've updated the XYZ Printing Software and now it no longer is creating that test strip.
I have been running the software on a small NetBook Computer running XP but recently moved the printer to my office where I have a iMac running Maverick 10.9.3 operating system. The software from XYZ Printing was locking up so an email to the tech support got a quick response and a patch version to try. It improved but still had some issues that they are working on. I hope to get a new patch soon.
The loss of the test strip though is irritating as it results in prints that have the discolored defect built into the part as seen in the picture below.

The print actually produces five valence clips and only the first one has the issue with the discolored print. So I sent these pictures to XYZ Printing and hopefully they can help resolve it. Maybe a setting changed that I don't know about is the cause but the software is pretty simple to use and I don't see a setting for test strip.
I'm getting very good prints out the printer with the replacement extruder. I like to run them in Excellent mode setting which defaults to 0.2mm height and 30% fill. This seems to result in very good quality prints.
Below is a video of the Davinci laying down the first layer. You can see the bead just roll out and stick perfectly (other than the first few strips). I believe this is what you want to see after adjusting your heated bed to extruder nozzle clearance.
I also don't add the suggested stick glue to the platform as the heat of the bed and the heat of the plastic are enough to hold it. Frankly, I find the glue somewhat useless to be honest. The heated of the bed just melts it and the stickiness is limited at that point. A proper set bed seems to do the trick.
