Middle chain ring issue

HI
I Currently installed a triple ring deore crankset onto an existing 8 speed rear cassette set up. Previous cranset was an stock suntour crank.
I have set the low screw and high screws to 1mm clearance. However I cannot get all gears in the middle chain ring. Can only get 3 to 7. (1 being smallest) If i adjust the cable tension I can get move this range but cannot get all 8 gears.
How can I cure this? Is there somethign I need to do with the rear derailleur?

And start again.
Presumably you have changed like for like in terms of gearing?

"As I said last time, it won't happen again."
Do i need to set the limits further out. They are already over 1mm on both highest and lowest gears which is the setting i have read is to be done??
If both these limits clear the highest and lowest I cant understand why I would only get 5 gears of range in the middle??
I have read numerous articles, but what is written doesnt seem to work on my bike?

what parts do you have? part numbers?
what is this 1mm you mention? there is a right place to set the first point for a mech and the rest follow from that.
read the info on Parktools and t5he info for YOUR mech and shifters.
Or tell us what you have.
