I've been getting some excess filament when printing.

@bcrazycramer i think it would be useful to approach the issue step by step. When doing a “home all” (G28) there’s not much that comes into place:

  • Homing direction per axis
  • Endstop switches

Depending on your firmware (i think you’re using Smoothieware which i don’t know too much of) you may also have additional settings like values for a move back when checking the home position or something like that.

As you’re getting good positions every now and then i wouldn’t worry about the firmware settings too much. I would check:

  • Is G28 always the command that is getting used (when homing manually via the Host software it should be but also in your starting G-Code?)
  • Are the endstops mounted well and can’t be moved by hand?
  • Do the endstops all feel well in their switching position or may one be broken and switch differently every time you drive into it?
  • May your bed be mounted unreliably? Does it come back out of the springs if you press it in?

You could also post your home/endstop settings from the smoothieware so we could look if there are unusual values. I was just reviewing the documentation for that (endstops [Smoothieware])

Here is the Azteeg X5 Mini config file:

I slapped (installed) Repetier Host on my desktop computer this morning and started up Eustathios Spider V2 and guess what? It’s printing like a dream. I have no idea why, but I’m glad it’s working.
