printer head crash to wall

Recommended Posts

Posted · printer head crash to wall

As the title says: My ultimaker2 printerhead has started to crash into the frontside.

 

Whenever I start printing everything starts ok. The printerhead moves to the "home position" as it should and stops at the right position. But when the printer head moves to the front, for extruding filament, it doesn't stop it before the end of the rail. Instead it just keeps going and grinds on the belts. After grinding for a second it moves back and starts printing and everything is fine. It stops fine in the other direction. It's only in the back-to-front direction it doesn't stop in the correct posisition.

 

So I have:

  • manually tested the switches and they work.
  • resetted the printer to factory settings.
  • updated the cura to 4.6.1.
  • tightened the bets

 

I have had the printer for many years and never had this problem until a couple of days ago. Any ideas how to fix this?

Could it be that you selected the wrong printer in Cura, or whatever slicer you used? Or its bed dimensions in Cura got corrupted?

 

Or else: defective SD-card, corrupt gcode files, hairs or dust in the SD-slot causing bad contacts (try blowing it out with compressed air)? Or something else along this line...?

I solved it!

 

I had set the gcode settings to "Marlin" instead of "Ultimaker 2", in cura.

 

Unfortunately, the temp settings in cura can't be made with Ultimaker 2 settings. So now I have to find how to set the start up gcode in Marlin. 🤷‍♂️
