Okay everyone I have been working on a new Zen for a long time now but I am really trying to get more serious about it.
I have all sorts of things that need improvement but here is what I have on my list.
-Try to make it so it fits in any current ZenXY table/build…at least the glass part. Trying to keep the same or larger “work area” within the same size constraints as before including the mechanism to glass gap.
-Low unique part count, unfortunately not the same parts as the previous Zen (expect steppers). I felt this was not a concern since the initial part count was really low.
-Fully constrained rails. The last one had chatter and did not lend well to you speed demons.
-Mechanically quieter, I am currently using small wheels (inexpensive).
-Same magnet, but hopefully room for more.
Differences (so far) that ya’ll might not like.
-Up to 10mm belt. Also means you have to use larger idlers. You can potentially use the same belts and pulleys though.
-2 sizes of rails. Currently I am using 3/4" for the long axis, and 1/2" EMT for the short axis. (I intend to make an international or two version as well).
-Shooting for no endstops but have not gotten that far. Trinamics are dirt cheap and allow for silent stepper driving (important) and they come with the ability to sense home. less wires and hardware. the cost of endstops and wires and wire management is probably the same as some trinamics. win win.
1- Open source? Keep it civil, I am asking for any pitfalls you might see. I feel like this could be a fun test into the fully open world. Any ideas to help keep the project profitable as well?
2- Threading into printed parts? I am trying to decrease the part size and not using nuts on some low force screws seems like a waste. Also saves on part count/cost. So threading M5 screws directly into plastic and orienting them to also work with gravity seems cool right? A drop of loctite can actually help if any of you have loose screw holes after printing.
3- Board options. Sensor less homing, small cheap? Headless?
