    Real nice project however the box was a silverchest not a cigar box...thats why the green felt my mom and dad had one and the green felt was soaked in so chemical to prevent tarnish.

  • How to Fix Bad Chinese Arduino Clones

    I have purchased several clone arduinos UNO and never have I had a problem.One thing you do not realize is that all high speed manufacturing is done in China and the units produced all pass the same test as any others. Now if you were to design a product yes you could do a test run in your own home country but when you need 5 million than you will need a high speed high throughput producer and that's where the Chinese companies shine so please stop using the word CLONE and stop being PREJUDICE as we all live in this world and when we are born we do not push a button to chose race,creed or color or birth location.Now check that you are using a data cable and not a CHARGING cable and if you truly get a bad device that send it back and a new one will be sent to you.

    mine is complete and I used a linear stepper rail from Amazon as the z to raise and lower the pen so I can use GRBL just like my cnc .It is a lot of work to get the axis lined up correctly.

  • Laser Cut SphereBot

    Yes on the drivers the big silver round thing beside the heatsinks is the current control pot you need to turn it down till the motors stop than turn it back up 1/4 turn from where the motor stopped this should fix the heat problem...never in over 30 years have I had to use a heat sink on a stepper motor.

    If the motors are getting so hot as you say then you need to adjust the current to the motors ,I have built and run cnc machines and have never experienced hot stepper motors,on the driver board there should be a variable pot that controls the current to the motor well you need to turn it to reduce the motor current or you could end up with burned out motors or worst a fire.

  • Replacing a CO2 Laser Tube

    ok here's what I just did ,today I found 1 little bubble in my tube and I could not get rid of it so after checking again on the net ,somewhere it referred to a chemical agent that makes water wetter with no suds and suddenly I remember looking through the window on the washer machine and no suds and I remember the problem with the toilet that was solved by pouring the new liquid type laundry abour half a cup into the toilet well problem solved...1 tablespoon of liquid laundry detergent into the water container and within 10 minutes the bubble is gone and the machine is firing perfect. The new liquid laundry detergent makes the water wetter with no soap.

    theres a vid on the net watch it and also insure both supply and return tubes are under water,also place the water container level with the machine with water level above the machine.

    the power supply may have a selector switch for either 115 /220 or look for a jumper which will be labeled 115/220 and set either the switch or the jumper to 220vac.

  • Laser Cut Pepakura Files

    There are 2 types of laser cutters.A laser diode and co2,for this project a laser diode cutter will work just fine provided the user has the knowhow to set it up and run it and you can purchase off ebay and amazon as low as $100 -$400 depending on the power rating of the laser itself now do not expect to plug and play(pray) be prepared to learn and learn and experiment for the first 6 months for someone with no experience with any type of cnc machine.Also remember you have to experiment to find the correct settings for each material you want to us.I started out years ago doing maintance on a 100 watt co2 laser @Vishay in Malvern ,Pa.

    One thing I forgot and it is the most important you must have the correct laser SAFETY glasses for your machine or you could lose your SIGHT in a flash.SAFETY FIRST.

  • K40 Laser Cutter: How to Cut and Engrave in One Job

    there are 2 layers one is RASTER and the other is CUT

    this is a real good tutorial,however the real problem is people buying these machines and not knowing nothing about setting up a laser/and using the design software.well heres the truth...It is NOT a CELLPHONE you need REAL WORLD experience and KNOWLEDGE to use this machine and you need to READ and UNDERSTAND the software.

    Its not closed source its on the net to download and use however if you have not used Corell Draw you will find it hard to use.

    you really need some graphics design experience ///just a dot will work as it is a zero point reference

    Check ALL the wiring CAREFULLY
