• cast on and ran first run
  • p4 yarn holder with rounded ramps seems to work pretty good
    • yarn moving smoothly down and under the hooked section
    • might remove 0.5 or 1mm from p4 gap height
  • need to figure out how to do micro stepping on drivers
    • lots of skipped steps and hang ups
  • still seems to be a diver overheating problem, will get heatsink and fan
    • hang ups increasing with run time/temperature it seems
  • seems there are a few needles that dont want to slide easily
    • need to disassemble and diagnose - sand paper on p2 inserts?
    • causing motors to hang up especially bad in certain spots
    • they dont seem to hang up as bad when machine is spinning ccw, not sure why?
  • smaller space between needles seems to be okay, no apparent problems
    • UPneedle2needle=9.12985;

• got lasercut parts
• assembled machine
  • new mountain design idea is not able to be removed easily
    • have to remove needles or disassemble plates
  • claws on p4 yarn holder have holes that are relatively too big
    • lower half is snapping off below the outer hole
    • could make smaller holes? or remove outer hole, bolt only through inner side?
  • aluminum angle iron holder needs some tweaking
    • when tightened all the way, begins to expand and let go around corner
    • maybe trim less on the internal side, make wiggle room larger
    • coud possible have a square nut in mountain to insert bolt on side
    • change to square nuts for back side, have to dissasemble machine to insert 30mm bolt
  • Need to make nut insert on Z bearing holder a little bigger
• Might add a M3 clevis bolt/hook to c4 paperclip holder
  • might help even weight?
