I decided to try out taulman’s t-glase filament on my Ormerod 2.
The result is quite good. But if you look carefully you can see the the top corners are a little higher than the surface. On the other hand, some of the other details seems more well defined than the same print made in PLA.
I used the Ormerod-0.5 settings in Slic3r, with these changes:
Bed temperature 65
First layer temperature 225
Other layers temperature 215
I started the printing with the head at Z=100mm to avoid heating the PLA around the extruder. However, the extruder temperature reached 225 degrees way before the print head was down to the bed, resulting in filament coming out of the nozzle. Because of that, the skirt was not printed. At 225 degrees it seems that the filament is melting and leaking, even when the extruder motor is at stand still.
Is it the lift curling the top. Or the over hot ext? You need a fan on extruder to keep it from melting? I haven’t ran but a small patch of nylon. I thought it’s temp was lower. Looks fun! Good luck!
225 sounds like a temperature for ABS. I have not used PLA myself, but I know it prints at a lower temperature. I have had some premature oozing with ABS. I often extrude and then retract 10mm or so before starting the print. Something in my settings also extrudes a little bit of filament before printing, so this works out well for me. Now if only I could get the rest of the setup to work well for me.
Thanks for you comments. I will try a lower temperature for the first layer, and change my z-lift settings. For t-glase the recommended optimum temperature is about 235 to 240, but it will print down to 212 and up to 248. I don’t know how well calibrated my extruder temperature is, but for PLA I use 185 with good results.
