      I am making a custom laser cutter with a build volume of 30"x20". I am using the GRBL 1.1 firmware on an Arduino Uno + CNC Shield with LaserWeb as the software for controlling it.

      I used this link here to get the correct screws, nuts, and bolts for my Laser CNC
      OpenBuilds ACRO System.
      -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
      Day 1 (5/28/2018):
      I have all the electronics and have installed the firmware on the Arduino. I have mostly assembled the frame but have not yet mounted the electronics such as the laser and the motors.

      Day 1 issues:
      The motors make a higher tone buzzing and vibrating sound and refuse to spin when told through LaserWeb and/or GRBL Controller. I have tried to reverse the motor connection but the same results have been observed.

      Day 2 (5/29/2018):
      Today I did a lot of research on how to fix my issue with the motors but lucky for me, the user Scotty Orr posted a solution to my problem. So, I looked at some videos on how to tune stepper motor drivers. I got them all to move using LaserWeb and I couldn't be happier.

      Day 2 issues:
      I accidentally turned one of the pots on my DRV8825 pots too much and now I can't tune it...whoops! However, I had a spare because I was smart and bought 4.

      Day 3 (5/30/2018):
      Today was really productive! I got the motors to move even better than yesterday. They sound even more quite today than yesterday and it seems to run very smooth. Tomorrow I plan to start mounting the motors and then to the frame.

      Day 3 issues:
      None to report.

      Day 4 (5/31/2018):
      Today I mounted the motors to the mounting planes and to the frame. It's starting to look like an actual laser cutter.

      Day 4 issues:
      I very quickly realized that I do not have the standoffs for the v-wheels, nor do I have some of the buts and bolts I need to connect some components to the frame correctly.

      Day 5 (6/7/18): I have bought more bolts, nuts, washers, and the right size v-wheels to finish mounting everything except the laser module.

      Day 5 issues:
      I ended up breaking one of the x-axis motor mounting plates, so I made a copy out of a similar thickness of plywood.

      Day 6 (6/14/18): Since everything is mounted I decided to add the belts today and check for tension and the smoothness of the movements on the X and Y axis. I also checked for alignment of everything.

      Day 6 Issues: Some of the wheels are a little tight so I loosened them and rechecked smoothness.

      Day 7 (6/21/18): Today was a big day! I test the movement of the laser cutter using LaserWeb4 and I couldn't be happier because I didn't break anything and it works.

      Day 7 Issues: I had some of the motor wires plugged in wrong and it reversed the motor directions. So I changed them to how they needed to be so they move how I want them to move.
