Turtle stops after one block - Possible loop error

repeat
  local success = turtle.inspectUp() --Is there a block?
  if sucess then --If there is a block, then dig.
	turtle.dig()
	sleep(1)
  end
until not sucess --Repeat until there isn't a block.

function digDown()
  local success = turtle.inspectDown()
  if sucess then
    turtle.digDown()
  end
end

Edit in every function this:

repeat
  local success = turtle.inspectUp() --Is there a block?
  if sucess then --If there is a block, then dig.
	turtle.dig()
	sleep(1)
  end
until not sucess --Repeat until there isn't a block.

I propose you, to edit your digDown function into this:

function digDown()
  local success = turtle.inspectDown()
  if sucess then
	turtle.digDown()
  end
end

function digDown()
  while turtle.digDown() do end
end

or even better:

Completely overlooked the use of ''if success''. thanks guys :D/> hopefully this helps

Edit: okay so i've added suggested changes but how can I get around lava and water? they don't return as false they return as "minecraft:flowing_water" or something similar. I also added two more if/else-if statements to each function so that it doesn't sleep if its not gravel or sand… The program runs really slowly though. Is that just the way it is due to processing speeds or due to the way i've written it? Also I am reluctant to add eniallator's ''do end'' function because I prefer knowing how the code is read by the computer so if someone could explain that in layman terms that'd be great. Thanks again guys.

basically the way that the function that i made works is by simply using the turtle.digDown() as the conditional in the while loop. If you would like to see for yourself and try it out, then try turtle.dig() (or digup or digDown, it doesn't matter) with a block that it will dig and without a block there/a block it can't dig. Basically the way the turtle.dig() (as like any other function of the turtle API) function works is it will return either true or false depending on whether it has successfully ran. In this case it will return true if it has dug a block and it will return false if it hasn't.

The reason that i have put the

while turtle.digDown() do end

is because its already trying to execute turtle.digDown() in the condition of the while loop so if i put for example turtle.digDown() in the body of the loop then it would run turtle.digDown() twice before it checks if it was successful.

Edit:
I just noticed you are checking for gravel/sand in the pastebin, This is not necessary for turtle.dig() because the function either is hardcoded to take a little longer or in the API theres a sleep() because if you have a while loop and you do turtle.dig() it is enough time for any falling sand to fall down and turn back into a block so if ran again it will dig the sand block rather than the falling sand.

function invCheck() -- Checks if inventory is full
local int = 1
repeat
turtle.getItemCount(int)
if turtle.getItemCount(int) == 0 then --\
int = int + 16 ---- If it finds an empty space then keep mining
local full = "false" --/
elseif int < 16 then
int = int + 1 ---- If the slot has something in it but its not the last slot, keep checking
else
print("Inventory Full!!") --\
local full = "true" ---- If the last slot is full then the inventory is full.
int = int + 16 --/
end
until int > 16

if full == "true" then
print("Press enter once a space has been cleared")  -- This pauses the program until enter has been pressed confirming space has been made
local event, key4 = os.pullEvent( "key" )
if key4 == keys.enter then
clearScreen()
print("Check in again soon!")
end
end
end

local int = 1
repeat
  turtle.getItemCount(int)
  if turtle.getItemCount(int) == 0 then
    int = int + 16
    local full = "false"--#Error is here
  elseif int < 16 then
    int = int + 1
  else
    print("Inventory Full!!")
    local full = "true" --# And here
    int = int + 16
  end
until int > 16

local x = 10
print(x) --#10
do --#This just starts another code block, think of it like an if or while or function
  local x = 200 --#Create a NEW local variable called x for this code block
  print(x) --#200
end
print(x) --#10

local int = 1
local full --#Say full is a local variable here
repeat
  turtle.getItemCount(int)
  if turtle.getItemCount(int) == 0 then
    int = int + 16
    full = "false"--#Set full here
  elseif int < 16 then
    int = int + 1
  else
    print("Inventory Full!!")
    full = "true" --#Or here
    int = int + 16
  end
until int > 16

The problem isn't at the bottom of that part, it's at the top. Read this tutorial for variable scope.

I will try to explain your problem.

local int = 1
repeat
  turtle.getItemCount(int)
  if turtle.getItemCount(int) == 0 then
	int = int + 16
	local full = "false"--#Error is here
  elseif int < 16 then
	int = int + 1
  else
	print("Inventory Full!!")
	local full = "true" --# And here
	int = int + 16
  end
until int > 16

When you determine that something is local, it only then exists inside of it's respective code block, for example this random code:

local x = 10
print(x) --#10
do --#This just starts another code block, think of it like an if or while or function
  local x = 200 --#Create a NEW local variable called x for this code block
  print(x) --#200
end
print(x) --#10

You're encountering that problem because you're creating a variable, and putting it as local only to the part of the if statement it is declared in.

It's an absolutely simple fix:

local int = 1
local full --#Say full is a local variable here
repeat
  turtle.getItemCount(int)
  if turtle.getItemCount(int) == 0 then
	int = int + 16
	full = "false"--#Set full here
  elseif int < 16 then
	int = int + 1
  else
	print("Inventory Full!!")
	full = "true" --#Or here
	int = int + 16
  end
until int > 16
