I know it has something to do with .ContainerOreSmasher.detectAndSendChanges...but i do not know what?

You never initialize this field, therefor it stays null.

I highly recommend you put the

final

modifier on fields that you will not change, because that would make this situation cause an error.

That fixed it...

Do i create another post...cuz it seems that i have new issue....

custom furnace recipe...for this machine dose not work.

As soon i place fuel in slot....block switch state from inactive  to active...even tough there is nothing to be smelted....ie no item in smelting slot.

 

I did add = to make it equal ...but still not working

Also, the general logic in

update

is flawed. You just set the current burn time without condition every tick. That doesn't seem right.

 

 

this better?

boolean hasBeenSmelting = this.isBurning();
	boolean changeSmeltingState = false;
	if (this.isBurning())
        {
            --this.burnTime;
        }

        if (!this.worldObj.isRemote)
        {
            if (!this.isBurning() && (this.Total_slots[1] == null || this.Total_slots[0] == null))
            {
                if (!this.isBurning() && this.cookTime > 0)
                {
                    this.cookTime = MathHelper.clamp_int(this.cookTime - 2, 0, this.cookTime);
                }
            }
            else
            {
                if (!this.isBurning() && this.canSmelt())
                {
                    this.currentItemBurnTime = this.burnTime = getItemBurnTime(this.Total_slots[1]);

                    if (this.isBurning())
                    {
                    	changeSmeltingState = true;

                        if (this.Total_slots[1] != null)
                        {
                            --this.Total_slots[1].stackSize;

                            if (this.Total_slots[1].stackSize == 0)
                            {
                                this.Total_slots[1] = Total_slots[1].getItem().getContainerItem(Total_slots[1]);
                            }
                        }
                    }
                }

                if (this.isBurning() && this.canSmelt())
                {
                    ++this.cookTime;

                    if (this.cookTime == this.furnaceSpeed)
                    {
                        this.cookTime = 0;

                        this.smeltItem();
                        changeSmeltingState = true;
                    }
                }
                else
                {
                    this.cookTime = 0;
                }
            }

            if (hasBeenSmelting != this.isBurning())
            {
            	changeSmeltingState = true;
            	BlockMachineSmasher.setState(this.isBurning(), this.worldObj, this.pos);
            }
        }

        if (changeSmeltingState)
        {
            this.markDirty();
        }
