Jeff's printer has arrived

nope first thing I checked it was free as a it could be. You should have seen how easily those layer snapped off and they snapped of completely in one piece just pop and off it came

 

Just a wee bit disappointing

 

The thing that makes this so special for me was that it was the first thing that I made that never existed at all. Yeah there were things that are very similar but not this exact thing. It started in my head I draw it up I amde everything fir and then I printed it out of a filament and it came into existance,

 

Yeah PLA red

 

some what the plan I had
I am checking to see if I need finer calibration on X Y Z right now then I am printing a holder for my dia lindicator so I can check bed levelness once I am happy with that then I will do a reprint on the cube

 

LOL you assume I have a procedure for leveling the bed I do not have that yet I had to take mine apart and put it back together so I need to check how bad it is
there is ome adjust I can do but not much
My piece of wood may also be bowed so if thats the case I hae towait for glass or something haven't decided yet

 

yep I can 't decide on aluminum or glass though seems both have pros and cons

 

Had some slight printer bed issue but I resolved them and wanted to go through thecalibrationobjects again this time with a little expereience behind me and the results were much better I ended up x 15.1 y 15.0 z 14.9 much happier and here are some of thing things I printed today

the calibration cubes the 5mm step cube with bridging and no support bridging is very cool. I also made atool to check bed level ness which snaps onto the x axis rods and you can check the highall along the y axis when x is near zero or at the other extreme did the fun pyramid which turned out amazingly well I also had a misprint with my tesseract plant o try that one again soon

Right now I am doing the Yosemite lithograph I made from an image of mine hope it turns out well as I plan to do several for xmas gifts this year with a little lighted stand. Other than that trying to figure out what happend ed to my cube it was about 25 hours into and only had about 2 left when it just died

 

On a side note my cuborg didn't go to waste in now is holding all those little pieces I have been printing which is what it was kind of design for so all is kind good with that

 

I tried to add the .stl to sliciverse but the system is having issues as soon as harry gets it fixed I will upload it there.

As far as the bridge goes it is not an stl it is how the software spans gaps with no support. I am not sure if I can get a pic of it on such a small item as it is very small but rather ingenious. I will try to explain what I see happening it may not be the actual way it does it but my explanation does correspond to what I see.

Imagine a you want opening in a solid wall, just say it is a square hole, but you do not want to add support how canit build the top with nothing under it. Well it doesn't it builds it from the back side of the hole it starts by printing a short line segment in the middle area of the opening now this may repeat for two layers I can't tell but soon there after it prints alight longer segment on the outside of the first segment in fact surrounding it and locking it to the back wall but now it extends out a bit farther. This forms a slight arc and this process is repeated until the edges of the opening are reach and the hole is made. Print this and without supports and you will see what I mean I tried taking pics with my phone but no luck.

the 5mm step pyramid

 

Ok this last print was both a success and a fail hmmmmm well it was a fail becasue i could have design it not need any support and use a lot less filament to get the exact job done so I failed the print the success was that in this print I oriented it sideways and I was trying to see how bridging worked and I was extremely surprised and happy it did work I had to span about 1 1/4 to 1 1/2 inches and the printer just laid a line as if it were nothing special and then another and so on and so on and it look liked garbage the filement strands were getting mixed up twisted stretched pulled yanked it was a pretty site but the filament stayed there the next layer came and the printer laid that next layer of filament right on top as usually only this time things were much less chaotic and substantially smoothed out layer three comes along and there are only slight bumps layer four and it was smooth as glass layer 5 was just frosting after that so the printer had succeeded in bridging a 1 1/2 in gap with honors in my book here are some pics

Third layer after bridging


Fourth layer



This will give you an idea what the first layer looked like
this is the under side of the previous images and this is what layer 1 was like


End result
Now I have to go design it the right way for what I wanted it for but this is still a bridging success as far as I am concerned
