Two questions:

First, is there a BOM for the Smoothieboard? I burned up two of the small MOSFETs and cant find the part numbers.

Next, what are the max values for the PID settings?

Hey everyone, I just upgraded my extruder from a Chinese knock-off E3Dv6 to an official E3Dv6 and need some help with surface finish. Printing TPU at 30mm/s with 0.2mm layer height. Top part is with official E3dv6 and bottom is with knock-off. On the old print the top section of the bottom part in the picture is very smooth. Using the same settings with the new extruder the wall is rough. Any ideas?

Anyone know why the temp stops 1 degree before the set value after an upgrade to an E3dv6 hot end? The target temp is 245 and I can get there when manually setting the temp but during a print it never reaches 245.

Im using the following config:

temperature_control.hotend.enable true # Whether to activate this ( "hotend" ) module at all.
# All configuration is ignored if false.
temperature_control.hotend.thermistor_pin 0.23 # Pin for the thermistor to read
temperature_control.hotend.heater_pin 2.4 # Pin that controls the heater, set to nc if a readonly thermistor is being defined
temperature_control.hotend.thermistor Semitec # see
temperature_control.hotend.beta 4375 # or set the beta value
temperature_control.hotend.set_m_code 104 #
temperature_control.hotend.set_and_wait_m_code 109 #
temperature_control.hotend.designator T #
temperature_control.hotend.max_temp 260 # Set maximum temperature - Will prevent heating above 300 by default
#temperature_control.hotend.min_temp 0 # Set minimum temperature - Will prevent heating below if set

# safety control is enabled by default and can be overidden here, the values show the defaults
#temperature_control.hotend.runaway_heating_timeout 900 # max is 2040 seconds, how long it can take to heat up
#temperature_control.hotend.runaway_cooling_timeout 900 # max is 2040 seconds, how long it can take to cool down if temp is set lower
#temperature_control.hotend.runaway_range 20 # Max setting is 63°C

temperature_control.hotend.p_factor 120 # permanently set the PID values after an auto pid
temperature_control.hotend.i_factor 1.951 #
temperature_control.hotend.d_factor 175 #

temperature_control.hotend.max_pwm 255 # max pwm, 64 is a good value if driving a 12v resistor with 24v.

Im running a firmware from mid 2015. Is there any compelling reason to get the lastest stable build and do I need to update my config?

Making more progress on my new micro quad. Still need to add the VTX and GPS modules. Almost there!

Designing my second multi-rotor. This one will be about 123mm motor to motor and CNC'd rather than 3D printed. What do you think?
