I was defaulting at 1200mm/min which was slow enough I can’t really hear anything but the ball against the table or sand. If I take the ball off it’s essentially silent. But I did enjoy the slower 600mm/min speed as well.
I hadn’t thought to try turning down the current yet…will try that next. Should also help keep the drivers cooler which brings me to:
I did some cleanup on the wiring this weekend - Designed a quick and dirty box for the 2 axis controller with some connectors for the steppers/endstops so I can still swap it between projects fairly easily:
Still need to finish the design with some ventilation, and a lid…but it’s a big improvement. I left slots for the uSD and USB on top so they’re easily accessible and left a slot for the WIFI antenna partly to make the box as small as possible and partly to give it a stronger signal.
Debating if I want a power switch on top as well…just pulling the power isn’t that hard…but a switch may be nice to have.
I also toyed with adding the M5 dial and buttons so it can be a self-contained controller/pendant but decided not to bother for now.
Also tried to add a bit of “sand containment” and “anti-cat protection” with a frame and sheet of glass:
I got some shuffleboard sand I want to try as “sand” - but it’s so slippery and will go everywhere if it isn’t contained. So I needed the surround. Unfortunately cutting the frame didn’t go exactly as anticipated so its’ not quite contained yet.
Oh well, doing it again gives me an excuse to do it right and get out the glass cutter and actually making it only cover the area it needs to cover. That was my initial plan but I kind of rushed just to get “something” done last night. Now I’ll slow down and do it right. Since I have to do it over maybe I’ll even finally get brave enough to try a tool change and add a chamfer with this 45 degree bit I finally have…
