Heating Extruder stuck at 98%

Support&troubleshooting Zortrax M200
#1

Hi All,

I just got my Zortrax M200 but it won't print, heating extruder keeps stuck at 98% for 1 hour, 2 hours.

I powered off, waited a while and powered on again and the same happens again.

it seems to loop at 98%.

I have checked the flatkabel, removed it  put it back in and power on again but doesn't help.

The only thing which get the print started is when heating extruder is stuck at 98% i remove the flatkabel and put it directly back.

This seems the only way to get out the loop and only than the print starts and prints perfect but that is not the way to go.

looks to me the firmware is looping in checking temp. ?

Have you "Forum members" any idea what's wrong with my new Zortrax M200

Regards,

Richard

It seems that Zortrax has a systematic issue in the latest printer batch that needs to be addressed quickly.

Ok, thanks I will have a look at this instruction but my new Zortrax M200 had this problem witht the first print.

I do not think it is the firmware since it is the same one for all printers.

It is difficult to help you since I do not know the strategy used by the M200 for controlling extruder temperature.

It might be a simple "heat the extruder till a certain value of temperature is reached then start to print" or it could use a PID regulation to precisely reach a defined temperature.

In this second case since energy is cut the more the value of temperature is near if the temperature sensor or the heating element are not in correct position the system will not ever reach the desired temperature .

Disconnecting the flat cable could reset the PID controller that start at the beginning of the cicle to give enough energy to overtake the 98% value and so start to print .

These are only hypothesis, I might be completely wrong ...

My printer actually told me last night that it was heating and to please wait. 

:o  :angry:

I didn't like it's tone so I turned him off and then back on and tried again. This time he went right to heating and didn't talk back!  :lol:  :lol:  :lol:

:D
