I was trying to bot some diamond bolt tips because I saw they have a nice profit margin but osfletcher doesn't seem to have that, and acerds fletcher seemed to be broken when I used it for that purpose. Change the RAW_MATERIAL variable to a different type of gem to cut that instead, but note that it is case sensitive: 

package boltTips;

import org.osbot.rs07.api.ui.Message;
import org.osbot.rs07.api.ui.Message.MessageType;
import org.osbot.rs07.script.Script;
import org.osbot.rs07.script.ScriptManifest;
import org.osbot.rs07.utility.ConditionalSleep;

@ScriptManifest(author = "theorems", info = "t", logo = "", name = "bolt tips", version = 0.1)
public class Main extends Script {

	private String RAW_MATERIAL = "Diamond";
	private int KEYCODE_SPACE = 32;
	private String FINISHED_MATERIAL = RAW_MATERIAL + " bolt tips";
	private String[] boltTip = { "Chisel", FINISHED_MATERIAL };
	private String[] unfBoltTip = { "Chisel", RAW_MATERIAL };
	private String[] makingBolt = { "Chisel", RAW_MATERIAL, FINISHED_MATERIAL };
	private String lastMsg = "";

	@Override
	public int onLoop() throws InterruptedException {
		if (getDialogues().isPendingContinuation()) {
			// when level up
			getKeyboard().pressKey(KEYCODE_SPACE);
		} else {
			if (getWidgets().isVisible(270, 14, 38)) {
				getKeyboard().pressKey(KEYCODE_SPACE); // this returns void
				sleep(random(500, 1000));
				getMouse().moveOutsideScreen();
				new ConditionalSleep(100000, 5000) {
					@Override
					public boolean condition() throws InterruptedException {
						return !getInventory().contains(RAW_MATERIAL) && !myPlayer().isAnimating();
					}

				}.sleep();
			} else if (getInventory().contains("Chisel") && getInventory().contains(RAW_MATERIAL)) {
				if (getBank().isOpen()) {
					getBank().close();
				} else {
					if (getInventory().isItemSelected()) {
						if (getInventory().getSelectedItemName().equals("Chisel")) {
							if (getInventory().interact("Use", RAW_MATERIAL)) {
								sleep(500);
							}
						} else {
							getInventory().deselectItem();
						}
					} else {
						getInventory().interact("Use", "Chisel");
					}
				}
			} else if (getInventory().contains("Chisel") && getInventory().contains(FINISHED_MATERIAL)
					&& !getInventory().contains(RAW_MATERIAL)) {
				bank();
				if (!getInventory().onlyContains(makingBolt)) {
					getBank().depositAllExcept(makingBolt);
				} else {
					getBank().depositAll(FINISHED_MATERIAL);
				}
			} else if (getInventory().contains("Chisel")) {
				log("only chisel");
				bank();
				getBank().withdrawAll(RAW_MATERIAL);
			} else {
				setup();
			}
		}
		return 500;
	}

	public void setup() {
		if (!getBank().isOpen()) {
			bank();
		} else {
			if (getInventory().isEmpty()) {
				getBank().withdraw("Chisel", 1);
			} else {
				getBank().depositAll();
			}
		}
	}

	public void bank() {
		if (getInventory().isItemSelected()) {
			getInventory().deselectItem();
		}
		if (!getBank().isOpen()) {
			try {
				if (getBank().open()) {
					new ConditionalSleep(2500) {
						@Override
						public boolean condition() throws InterruptedException {
							return getBank().isOpen();
						}

					}.sleep();
				}
			} catch (InterruptedException e) {
				log("Error banking: " + e.getMessage());
				e.printStackTrace();
			}
		}
	}

	@Override
	public void onMessage(Message message) throws java.lang.InterruptedException {
		if (message.getType() == MessageType.GAME) {
			String msg = message.getMessage().toLowerCase();
			String er = "you don't have enough inventory space.";
			if (msg.equals(er) && lastMsg.equals(er)) {
				log("Shutting down for safety");
				stop();
			}
			lastMsg = msg;
		}
	}
}

EDIT: completely rewrote the script except for the msg failsafe. It is now quite robust, I tried to break it in every way I could think of and was unable to do so.

Complete rewrite

Lots of tinfoil and stuff that will break within 2 weeks  

Edit: Not a bad try though

The thing I know that might break after 2 weeks is the widget ID which will probably change when rs updates. Anything else you see which could break easily so I know for the next script I make?

I completely re-wrote it except for the onMessage() -- no tinfoiling this time!
