Graber i3 Questions
June 29, 2015 07:57AM
After lots of messing around all sorts of problems I have manged to temporary rig this graber, It homes ok test run some gcode.


My endstops are the best placement, I could do
What I need to print

endstop holders
belt holders
lm8uu pillow blocks
compact extruder / swap to all metal hotend
reel holder

All I have is nylon black, 3.00 and 1.75 210~260 deg, Is nylon good enough, do I need abs for extruders?

p55nf06 mosfet heats like crazy If I turn the heatbed on, It has a copper heatsink and fan, I'm waiting on x10 IRLB8743 TO-220 from china, Does maplin.co.uk have any transistor which would work as a replacement?

Try stabilizing the 5V by adding a red cable from the PC PSU to the "+" connector of a servo or endstop port. Disconnect D1 diode from Ramps, too.
This might help your P55 FETs to run cooler.

About nylon as print material, read [reprap.org]
I´d recommend looking for PLA for starters.
