Hi All! Got some issues with my second hand Duplicator 4 that i was hoping someone could help me with.

Howdy,

I was wondering if you could please help me diagnose some issues I’m having with my second hand duplicator 4.

When the z axis / HB lowers all the way :
The print starts, the bed won’t raise unless i put my finger under it with a TINY amount of pressure then it raises. Running latest sailfish


Thanks

PS: I’m running a mac and tried replicatorG and makerbot applications
