Problem: Article: This is the optimal placement to achieve a quality result. If your material doesn’t fit, you will need to trim it down so it can fit flat inside the machine without bending up at the sides. Press any key on the keyboard, this will cause the laser to test its dimensions across the mat. If the laser moves outside the area of your material, reposition the material so that the laser doesn’t move off the edge of the material.  Don’t forget to resize your image if you trim the material. If your material has a bend in it, place a weighty metal rod on the edges of the material to hold it down. Dampen a piece of cotton wool with rubbing alcohol and lightly rub the lens of the laser cutter. This can be done while the lens is still in the machine. Purchase rubbing alcohol from a drugstore or grocery store. Most modern laser cutter will have an automatic lens height sensor or button. Once your material is in the correct position, press the “adjust lens height” button on the machine if the machine doesn’t adjust automatically. Adjusting the lens height will focus the laser at the correct level. If there is no lens height button, you will need to adjust the height manually. Read the user manual of your laser cutter model to find out how to do this, as the process varies between models. Press the on switch on the fume extractor. This is the large tube located behind the laser cutter. The fume extractor sucks all the fumes and dust from the material out of the laser cutting machine. Don’t use any materials that contain chloride, even if you are using a fume extractor.
Summary: Place the material in the centre of the laser cutting mat. Clean the lens with rubbing alcohol. Set the lens height. Turn on the fume extractor.

INPUT ARTICLE: Article: Open the window and/or run a fan. Wear non-porous gloves, a mask, and safety glasses. Chlorine bleach is an eye and skin irritant. The fumes can affect the respiratory tract. Adequate protection and ventilation are essential. Mix three parts water to one part chlorine bleach. Alternately, you can purchase a cleaning solution that contains some bleach.  If your grout is colored, using bleach may cause it to fade, especially if used regularly. You can repeat this method with a slightly higher concentration of bleach (for example, half bleach, half water) if the 3-to-1 ratio doesn’t work. Never attempt to mix other chemicals with diluted bleach. For example, ammonia – found in many cleaning agents – emits toxic fumes when mixed with bleach. Thoroughly wet any tiles in the area with warm water before using any bleach solution. Even if you’re just cleaning the grout, spatter will land on tiling. Pre-wetting tiles with water saturates them to limit their absorption of chemicals. Use a narrow brush such as an old, stiff toothbrush or any natural bristle or nylon brush. Scrub the grout with the solution in small sections. Bleach can lighten mold so that it isn’t visible. Scrubbing is needed to reach into grout’s pores and remove organic growth. Let the solution remain on each section of grout for about three minutes. Then rinse it clean with clear water. Letting bleach sit for more than a few minutes can cause staining, streaking, or even breakage to tile. Buff away any remaining moisture with clean cloths. Leave the window open or fan running until the grout feels totally dry.

SUMMARY: Ensure proper safety and ventilation. Make a diluted bleach solution. Wet tiles with water. Apply the bleach solution. Soak and rinse the grout. Dry the grout.

In one sentence, describe what the following article is about: Sometimes, overflow happens. In fact, it’s happened to most at one time or another. If you bleed through onto your sheets at night, rinse the sheets in cold water and then immediately put them into the wash. If you bleed into your underwear, you can try washing them (separately or with dark colors), or just throw them away at the end of the day. Worst case scenario is that you bleed into your pants or skirt – do what you can to get through the day by tying a sweater around your waist or, if you must, going home early. Shower, change, and move on with your day stress-free. Talk about your accident with someone you trust. Remember that 50% of the world has dealt with periods – it’s likely that someone you know has had an overflow accident, too. Don’t be ashamed or embarrassed to talk about it and how you feel. If you’ve experienced overflow bleeding, be prepared for next time. When you’re on your period, wear black underwear and pants. If you do have some spotting, it won’t be noticeable. You can even set aside a set of dark undies to wear only when you’re on your period. Using more than one type of menstrual hygiene product can be really effective in minimizing overflow bleeding. If you sometimes bleed through your tampons, use a panty liner or pad, too. That way you have some backup in case you don’t get to change your tampon in time. THINX period panties can also be a good backup method to a cup or tampon. THINX are made so that you can bleed right into them, then wash them out and reuse them. They hold anywhere from ½ to 2 or 3 tampons worth of blood depending on the style, and are available to purchase online. Get used to “checking on things” every hour or two. Make a quick bathroom stop in between classes or as a short work break. Check your underwear and pad, and do a wipe test if you’re using a tampon – if there’s blood on the toilet tissue after you urinate, you may be about to bleed through your tampon. Put a dark towel down on your sheets while you sleep to protect your bedding and mattress from accidental leaking. You can also try using overnight pads that have wings; these offer more protection from spillage.
Summary:
Stay calm if you overflow. Wear dark clothes and underwear while on your period. Double up on your hygiene products. Be vigilant. Protect your bedding with towels.
