Hi, here is my first really impressive (to me ) print, done 4 of these at once using 3mm pla and 0.25 layer height, as you can see cleaned 1 three to go, back to it i suppose .....

Great looking print!

Nice looking prints!

It looks like you got a bit of extra plastic coming out of the extruder during moves from one object to another. Are you using Slic3r to create the gcode? If so, you can increase the amount of retraction that occurs when the extruder is moving, it would help eliminate some of the extra cleanup and waste.

Im using Skeinforge and i have tried a few times to reduce the strings but thats the best i can get them, any advice ?

Sorry, not really a skeinforge user. I know there is a feature called oozebane that is in skeinforge to control when the extruder is turned on and off, maybe check out the following wiki for details/info and extrapolate needed settings for the H-1 extruder?

It took me a couple dozen prints, each one tweaking settings in Slic3r to get bridging, retraction and others working just right.
You may just have to try settings and print, check, adjust, print, check, etc...

Best of luck,

Mike

I was printing this as I was typing my last reply. Here is what Slic3r can produce with 0.28mm nozzle running at 0.10mm/layer. This took 1h:48m:12s to complete.

If you want to try Slic3r, let me know, I can give you my config ini file that I use, you will just need to play around with some printer settings, nozzle size, layer height, cooling, etc.

Now that is a well defined print, the facial features in your print are definately sharper than the one i done, could i have your slicer config file please ?

Thanks

Hey g1r9a6d8y,

Attached is the config file I use with Slic3r (0.8.4). The printer size is incorrect, but I never set the right dimensions, nor does it matter. Just have to remember to not print stuff too big to fit in the H-1. Also, make sure the parameters (extruder diameter, layer height, etc) are what you want to use.

The file is named Ultimachine_Filament_1.80mm because I have different configs for different vewndors/sizes/melt temps, these will probably work fine for most 1.75mm filament out there, but best to double check.
Let me know if you have any questions.

Regards,

Mike

Nice looking prints there Mike!

Thanks John. These prints are with the new 0.28mm nozzle running at 0.10mm/layer. Pretty cool. I have found that for items with detail or vertical curves, the best print quality comes at 0.10mm per layer, for others like cases, straight walls, 0.20mm/layer is better and faster.

Very cool stuff! I can't wait to get my H-1.1 upgrade and see how much better this machine gets!
