David Crocker has been working on his Delta 3D printer project:
After performing this upgrade, the printer is much quieter than before. This is because of the change from x16 microstepping on the Duet with A4982 drivers, to interpolated x256 microstepping on the Duet WiFi with TMC2660 drivers. The noisiest component is now the 40mm electronics cooling fan under the bed. I shall search for a quieter 40mm 24V fan, or perhaps do a small redesign of the electronics rear panel to use a slower-running 50mm or 60mm fan instead.
Another benefit of the upgrade is that I can now use the printer in a different room – as I occasionally need to do when hosting meetings – without needing to run a communications cable to it. The gcode file upload speed over WiFi is about 800 kbytes per second, similar to the speed I was previously getting with wired Ethernet on the Duet 0.8.5.
