Rattle on start or stop...

Hey all,

   My excellent son bought me a Monoprice 3D printer for xmas. I have been playing with Blender, CURA 15 and created a project. I have learned a lot about ABS this past week and have the printer heating up to 230/80 and the print looks great.

   However, every time I turn on the printer or the print jobs finish, the print head runs to home and rattles like it is being told that home is somewhere off the grid. Of course, my concern is it will eventually destroy the belts.

 

   You guru's out there, what is happening and/or is my fear accurate? BTW... for an older Geek like me (56)... this home capability is absolutely fantastic. It really plays into my ADHD/OCD wheelhouse. :-)

 

Thanks for any pointers you can offer.

Hey,

 

  • So from reading this post it seems like there is something wrong with your end G-Code, to explain more, G-code is the language printers speak. So when you take that .STL model from your 3D cad software, it loads into cura. Cura acts as the translator and changes the .STL language into G-Code. You can modify your end G-Code. I personally would get rid of the end home, just for simplicity. In the end G-Code I would have it shut off the heaters and disable stepper motors. This will then allow you to move the extruder head to where you want it. Use google to find how to edit your G-Code 

 

EX:

 

M104 S0 ; turn off extruder

M140 S0 ; turn off bed

M84 ; disable motors
