Dual extruder head crashing

[bman 2]

I have noticed a continuing problem with Cura with regards to third party dual extruder printers.

 

I f you use your printer without enabling the prime tower or ooze shield everything works fine, i.e. no crashes.

 

If you enable the prime tower or ooze shield, and don't look at the prime tower location, it could be defaulted off the print bed. This results in a crash.

 

Cura does not earn you that the tower is out of bounds and slices the print without warnings. This happens with either the prime tower or ooze shield enabled.

 

If you expose the prime tower location it is red, signifying and error, but only if it's visible.

 

Cura should warn users and prevent slicing if the print head goes to the beyond the safe travel area as setup in the machine settings. This way user's know there is a problem and what is the cause.

 

Thank you

Bernie

I am not an expert for the printer definition files, but I guess there are the "not allowed" areas defined and also a default location for the prime tower. When you just add a custom printer in Cura you will miss some features of the definition files. Take a look on Github, there is a wiki with some deeper information about the printer definition files and then check the included ones to get an idea how to create your own.
