Welcome to the SeeMeCNC Community

Not sure what i did, but i downloaded an autocad file, exported it as STL then opened it up in MatterControl and shrink the size down a little.

For some reason the head was printing way off the bed and all i did was shut it off last night after it was printing fine.

So then i figure i will try to re-home the towers on the glass and when i click the Home all (G28) it just moves the head down like .5 inches each time i issues the command, whats going on?

I would do further research on the forum about Home issues. I just had the same issue and I ended up clearing the EEPROM and reflashing it. This worked immediately. However, if you look at my posts I ask many more questions then any I have correctly answered. Hope you find the solution.

This thread helped me..
