There's things that are missing from this list, but I'm out of coffee. Also pick up a can of dry silicone spray. Just attach to the end of a drill and run them through the blocks a few times. You may notice that your lead screws will be tight in the nut blocks. If you need more accuracy, you need to cut a square, measure and do come calculations: Its located in the Grbl Settings tab next to parameters $100, $101 and $102. You can get very close with the built in fine tune wizard in OpenBuilds control. Go to 27:00 minute markĪnd another video showing after fully assembled. However, its easier to get them pre-adjusted before. The OpenBuild video shows adjusting them after the machine is fully assembled. This seems to be frustrating to people who are just starting out with these types of machines. I've been meaning to post a FAQ for some common things that come up during/after a build but in the meantime, here's a list (not complete). (metric gcode is mandatory btw).įor the mechanical build side of things, the build videos are good. I use fusion and model/cam everything in imperial, then have the post processor create the g-code in Metric. It might be a bit annoying at first, but you'll get use to it. You dont need to know much about grbl since there's a built in config for your machine but it does help to have a basic understanding of the configuration settings. The good news is that OpenBuilds Control makes things pretty simple.

Since you're going grbl based, then use the following post processorsįor Fusion: swarfer/GRBL-Post-Processor Here's how to use a custom post in fusion: How to install a Personal (local) Post Processor in Fusion 360 CAM | Fusion 360 | Autodesk Knowledge Networkįor Solidworks (note, I haven't used this personally, but I believe its the one you want): CAM Post Processor - CARBIDE 3D SHAPEOKO You can use an arduino with the Gecko which is probably better: g540, mach 3,4 or other? The DRV8825 drivers are under powered, even for the 175oz motors.
