Re: Breaking my 1.75mm PLA
Looks like my e stepper motor could be a bit better aligned but it's pretty good and the filament has no trouble feeding down into the brass shaft. I'll take the feeding mechanism apart and align it a bit better.
I'm going to pass on implementing pronterface until after I fix the breakage (stripping?) issue. One problem at a time is frustration enough.
Though it looks pretty cool.
I'm not sure of the version number but the firmware date is 20110107. It's the only one on the Mendel-Parts site that seems to work for me.
Since I'm using a direct driver extruder I set E0_STEPS_PER_MM 152.8930446.
I don't use the same computer I print with to generate my gcode. I'm using an MSI Netbook to print from and a much faster and user friendly desktop machine to create my stl models (Autodesk 123D) then skeinforge to create the gcode. I then put the gcode files on a network share and load them into repsnapper on my netbook.
I have my skeinforge settings set up as I've seen others here do. I let repsnapper control the hot end temperature. I don't recall having set any of that in skeinforge.
Pronterface has at least one feature I whole heartedly love. Being able to tell the printing software how much travel your x,y, and z axi have is a good thing.
First of all, look if the filament goes straight through the Extruder in the hotend. The extruder motor should not push the filament in a curve (this was my mistake in my first attemp
Second forget repsnapper, use pronterface it is better (But this has nothing to do with the breaking, i guess). But what firmware do you use? Have you installed the latest Marlin-Firmware?
What Speed is set 3000? I have at this moment a Main Feed Rate (mm/s) of 60.0 (I use sfact, for easy settings)
