[What is "Print Jerk"]

Great explanation, but exactly does enabling this do?

[Ultimaker 3 Extended control board]

Good Day,

 

Thanks for replying.   I am in New Brunswick Canada.  The only thing that happens is the exruder fan will turn on for approx 2 or 3 seconds,  then nothing happens.   The Olimex board has a red LED illuminated.  I attempted to flash the firmware again with instructions from the dealer and nothing happened (no LED flashed).  I suspect a bad Olimex board.

[Carbon fiber filament]

What temperature are you setting to print for this? 

 

 PLA print temperature is typically 185 to 205  degrees Celsius.  Carbon fiber is a bit higher  

 

Carbon Fiber Print Temperature typically is : 240-260 degrees Celsius

[Ultimaker 3 Extended control board]

Does anyone know the make and model # of the control board used in the Ultimaker 3 extended?

 

We just got ours and it printed 1 thing,  then the limit switch would not detect the print head on the X axis.  Now the printer will not power on.  I am in contact with the dealer,  but I would like to have some info going into this problem.

 

 

Thanks
