I am glad solder paste dispensing is working well. The team was all smiles after reading your post
Rotating the card in SW
You probably would have discovered this eventually, but you can actually mount the PCB in any orientation you wish. As long as you teach the V-One the location of two pads it will automatically rotate the design in software and compensate. To demonstrate, I just mounted a Hello World board at 45 degrees and located 2 pads. This is the result:
If you have connectors going all the way to the edges (or a very large board) it will certainly be awkward to secure the board . We've encountered the same issue a few times ourselves and our go to solution is to use some Kapton (Polyimide) tape to secure the board down.
We prefer Kapton since it will not leave adhesive residue (unlike electrical tape) and it is high temperature. This means that you can leave the tape on during the reflow cycle and the tape will come off clean afterwards.
If you adjusted the height (Z) during a print, the software will remember it for you for your next print, even if you restart it.
Out of curiosity - what height (Z) value did you end up choosing? The default for paste is 0.14 mm.
The E value is a relative value, clicking + or - simple rotates the gear and will push or pull the plunger inside the dispenser by a tiny amount. It doesn't really make sense to 'save' that value. It's a value that might have to be tweaked every time you print.
With that said, if you are careful with the dispenser and you do not move the gear by hand after it has been calibrated, you should not have adjust E the next time you print.
If you have some cool boards that you've dispensed on, and you are comfortable sharing them, feel free to post them here or in the #madeWithVoltera post.
