ERROR: Producer.produce()

I've encountered the following problem, and i havent got a clue where to start
Google and the reprap forum produce 0 answers

ERROR: Producer.produce(): bottom-up builds no longer supported.

I suspect it has something to do with my settings, but that's just a guess.
I'm running the latest reprap software and firmware.

When i start a print job the following happends:
- the machine checks the endstops
- extruder heatup delay
- produces error in console
- checks endstops
- displays "finised" message in reprap software

Thx

found the following reference in Producer.java

if(layerRules.getTopDown())
	produceAdditiveTopDown(gp);
else
	Debug.e("Producer.produce(): bottom-up builds no longer supported.");
	//produceAdditiveGroundUp(gp);

Isnt a reprap a ground-up building device??
I think i have the terms mixed up or something

I reverted to a previous version and everything is fine there.
Looks like there were some changes in the latest 2 versions, maybe it isnt 100% yet.
Will keep an eye on it.

Hi

Did you ever find the cause of this?
I have the same symptoms, and regressing to a really old version does stop this error (but introduces others, making it useless)

Thanks

Are you still using an old preferences file? Try moving the preferences file to a different location so it is not picked up by the application and see if the error still happens.
