  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Metal lathe options

    What is the required HP to work metal? I am looking at the affordable 8 x 13 wood lathe from KMs tools https://www.kmstools.com/king-canada-8-quot-x-13-quot-variable-speed-wood-lathe.html However I'm not sure if it can be used with metal. What exactly is the difference between a metal and wood...

    Laser Engraving

    Before I got the laser engraver, while I was making a lot more jewelry, I had tried my hand at hand engraving with gravers and a graving vice. That method gives you much more control of the depth and angle of the engravings, but takes quite a bit of patience and control.

    Laser Engraving

    I'm thinking that would work even better. I'm not all that confident that non burned cermark would work as a good resistant to feric chloride; and the laser engraver would most likely be powerful enough to burn off the nail polish in a precise way.

    Laser Engraving

    That's a great idea for the cermark that I'm still working with. Though it still doesn't leave a permanent mark, I have found a setting that is more difficult to remove than every other setting. In that case I I'm thinking it might act as a good resistant to ferric chloride which is what I use...

    Laser Engraving

    This engraving is much more visible than the first. Since I decided to run two passes at full power, it actually engraved the steel instead of just oxidizing the surface. The way the engraver fires bi directional left and right is very noticeable. I still feel the individual lines would blend...

    Laser Engraving

    Yeah I discovered how Inkscape can trace the outline of a picture and convert it to a dxf file. That is required to use the plasma table to cut or mark a decorative image; however, most laser engraving platforms don't require a CAM program to first process a dxf to G code. Inserted images are...

    Laser Engraving

    CO2 lasers, fiber lasers, and solid-state lasers are only realy designed for cutting, because you don't have much control over the optical power output. Unless a smaller tube is installed it would only ever cut the material. Diode lasers like these modules built with multiple diodes give you...

    I ordered the 2 oz Cermark ultra laser marking aerosol off Amazon. I was looking at the Brilliance Laser ink which is much cheaper, but the reviews are not good. Every laser metal marking compound I have found online only marks the metal with a permanent black mark. Only glass marking compounds...

    Laser Engraving

    Yeah, this machine does have a pretty simple focusing system. I cant remember what the focus was when I was trying to cut resin infused birch made for knives. I tried to cut it with 100% power at, I think a speed of 20. It did not go deep at all. I should try it again focussed at 1mm. The...

    Laser Engraving

    That was one of my first arduino projects after got my plasma table. The gantry was easy enough to make with stepper motors, but the module I had could only engrave soft material like wood.
