The extensible Y-axis parameters (depending on the paper used, etc.).Since we had decided to create a painting machine on wheels rather than using a rack and pinion for Y-axis movement, a number of issues need to be accounted for in the software:

INSTALL COOLTERM SERIAL

Using the TinyG JSON server and the serial port used by our TinyG board (ls /dev/ttys.*) we were able to connect the TinyG to three motors, and have it running all three axes at once. We're not sure if this was just a connection issue, but a top speed of F600 was achieved after reconnecting one of the motors. After some adjustments, this number fell to F250. However, we struggled to find a point at which the trimpots affected the upper limit, while the motor itself refused to run at higher than F380 without stalling, which seemed like a relatively low speed. According to the TinyG documentation, we could use the trimpots (plastic screws near each motor input) nearest to each axis to fine-tune the amount of voltage going into each motor. Overdriving the motor draws more current and results in overheating and thermal shutdown. The next step was to find the limits of the stepper motor which turned out to be quite challenging. A standard block might be 'G1 F400 X300', indicating linear interpolation 'G1' which finds the straight path between the current position and the next, an 'F400' feedrate of 400mm/minute, and a movement to 300mm on the X-axis, depending on whether the movement is set to relative or absolute. We then proceeded to spin the motors according to the default G-code presets.Ī note on G-Code. We then wired the motors by finding the coil pairs which was fairly simple. We then set up Coolterm and established a simple serial interface with the TinyG.

The next step was to establish the USB connection and install the FTDI drivers for Mac. For our initial tests, we used the power supply available in the arch shop, and set the voltage to 24 volts. We made sure to wire the power input correctly. The first step was to connect to the power. If your Mac is set to allow apps from the App Store and identified developers, the first time that you launch an app from an identified developer, your Mac asks if you’re sure you want to open it.SThe documentation provided for TinyG was quite exhaustive which made the process of setting up and testing the TinyG a lot easier than we had thought. You may want to look for a later version of the app in the App Store or look for an alternative app. If you see a warning, it means that the app has not been signed by the developer, so macOS can’t check whether the app has been modified or broken since it was released. For example, some apps were written before Developer ID registration. These messages don’t necessarily mean that something is wrong with the app. 'Example-app.app' can’t be opened because the identity of the developer cannot be confirmed. Your security preferences allow installation of only apps from the App Store and identified developers. 'Example-app.app' can't be opened because it is from an unidentified developer. If your Mac is set to allow apps from the App Store and identified developers, and you try to install an app that isn’t registered with Apple by an identified developer, you also get a warning.

If you have set your Mac to allow apps only from the App Store and you try to install an app from elsewhere, your Mac will say that the app is not from the App Store. Please change "Allow apps downloaded from: " to "App Store and identified developers" If you see a warning message and can’t open an app Select App Store under the header “Allow apps downloaded from.”

Click the lock and enter your password to make changes. In System Preferences, click Security & Privacy, then click General. For additional security, you can chose to allow only apps from the App Store. View the app security settings on your Macīy default, the security and privacy preferences of your Mac are set to allow apps from the App Store and identified developers. With macOS Mojave, developers can also have their app notarized by Apple-an indication that the app was uploaded to Apple and passed a security check before it was distributed.

INSTALL COOLTERM SOFTWARE

When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature and notarization status to verify that the software is from an identified developer and that it has not been altered.

INSTALL COOLTERM DOWNLOAD

If you download and install apps from the internet or directly from a developer, macOS continues to protect your Mac. If there’s ever a problem with an app, Apple can quickly remove it from the store. Apple reviews each app in the App Store before it’s accepted and signs it to ensure that it hasn’t been tampered with or altered.

The safest place to get apps for your Mac is the App Store. MacOS includes a technology called Gatekeeper, that's designed to ensure that only trusted software runs on your Mac.
