Hi new to this 3d printing fitted this glass to hot bed but now find that when the extruder unit parks hitting the bed.How do I adjust this so it doesn't happen. Print is great now since bed is really level now.

What do you exactly want? Heating with extruder not touching bed? I guess G28 is responsible for this and you have it in your slicer start gcode. Just add a 
G1 Z10 F600
after it if you want to heat with extruder in the air.

Thanks for that I will try later today

Still having problems with the extruder touching the print. Have levelled bed and increased z hop to 2.0 and still hits the print .

When does it hit the print? Even without hop that would normally only happen on flat angles with warping. If you hit bed at layer 1 printer is not calibrated correctly. G28 should at best just slightly touch the bed, so that first layer 0.2mm would not hit it at all.

Normally hits the print during infill and long runs.

If it happens later in the print and not on layer 1 it is normally not leveling dependent. Is your extrusion well calibrated? One other reason is when you extruder more then needed for 100% so the extra filament stacks up until you hit it. Without images I can not say more, just wild guesses.
