New extruder fitted, j-head away it goes! My old ptfe extruder head finally split, will see if I can remake it using PEEK
New ahead extruder fitted
Printed base for sang board
And for fun…
After a while my retractions settings were not looking great. looking at slic3r a bi more closely, i realised the settings for retraction speed was in mm/s not mm/min, therefore the setting of 30 was causing the stepper to screetch!
i reduced this down to 4mm/s and 4mm retraction which was painfully slow, so a quick q on REPREP IRC channel brought Dreamscape74 suggesting their settings.
Now retraction is set at 14mm/s and 2mm retraction length.
Now onto the brige test…
Just on break, and worked out accurate settings to solve excess plastic going into the extruder, New settings for ex stepper was 700, New are 630 steps per mm
Trying this version of the prusa, my new red model, featuring prusa 2 parts, I am printing running slic3r 0.9.2 and am having funny print results, the parts are somewhat blobby
Not sure what is causing this, could it be I have moisture in my pla? I hope not! I don’t keep it in a box with decad stuff, but I thought it’s ok on my makerbot… Anyway, I’m having a few issues so I need to work on the settings still
However on positive note, I tried the new dual print separate print commends on slic3r, looks good!
A note, before I printed these u tried a motor housing, excess plastic in corners and odd stepping in the plastic straight lines… Hmmmmmm
Not sure about that either, any ideas?
Turns out my prusa heat bed mounted directly to the MDF board on my Y axis is heating the pla belt
mounts causing them to melt slightly ans loose grip of the belt. Major issues. Should I mount the bed on standoffs?
Quick solution… Make some from aluminum
