extruder height

I'm new to Coura. I've been using slicer but looked at coura and it looks as if it has a better fit for me. I'm fairly new to to 3d printing. I uploaded the stl file..made some changes in coura and started printing...notihing complicated..just a flat piece with some lettering on it...
 

here's the problem. When the bed gets to operating temperature, 60c  ...it moves the extruder to the home point, except it parks the head about two inches off the heated bed. Then when the extruder gets to 210, the head starts moving and filament flows from the head while at the same time the head is lowering towards the bed.  It's not going to work that way....but everything is okay....

anyone ever run into something like this?

 

It's a sintron ultima 

 

thanks  rb

If I am reading you correctly then what you describe is normal, minor differences depending on printer/firmware. Depending on how well your printer is setup, one of two things will happen; either the filament will immediately stick to the bed or it will not, in which case you will drag some filament along the bed before it does stick. It is advisable to print with either a brim or a skirt, which does two important things. Firstly it will keep the string of extruded filament away from you model; secondly this allows the pressure to equalise before it starts printing your model.
