Print head chrashes into corner

[ManAtArms 59]

Since this week i have a curious problem with my Ultimaker 2+...

When i finish a print, let it cool down and print a new file again, the print head chrashes into the left back corner and does not stop until i flip the switch.

I had this problem right now again, it looks like the endstops do not send a signal to the board, but they are all okay and work when a print is finished.

I use Tinkergnome 17.10.1 since a month now and everything works great, till that happens after the cooldown phase and starting a new print without restarting the printer.

After i restart the printer, everything is working again as it should.

I have some other problems too, but they were mostly solved and have nothing to do with this.

I have the printer about two years now and maintance is done regulary each month, but the most problems started early summer this year or better said, since the waranty is over.

It also got a Bondtech DDG extruder a while ago and some other stuff.

 

Could it be a bug in the TG firmware? I do not want to change it, i like the system and the infos it puts out very much.

 

EDIT: Problem solved, it is a bug in the firmware, can be closed!

Can you elaborate it a bit more? I also use 17.10.1 but haven't seen the bug yet.

Sure 🙂

 

After a print ends, you let everything cool down and then start a new print, it can happen (it musn't) that the system doesn't register the endstop switches and drives the printhead into the corner till you abort the print or cut off the power.

 

The reason of this could be the geek mode, disabling it can provide less stress on the system, as i read it.

 

I powercycle the machine now after each print, i don't want to change the belts tjat early.

Thanks! Yes the geek mode could be the reason I haven't seen it yet, I have turned it off.
