Hello zapta!
can you explain why you chose that relatively large syringe size? Wouldn't a smaller one (e.g. 10ml) will give you even faster vacuums control?
There’s several reasons, first and foremost volume. As you can see the leadscrew and piston occupy a large space inside the syringe which reduces dispensing volume roughly by half, using a 10cc syringe would leave just 5cc of effective volume which I don’t consider acceptable, especially for adhesive dispensing.
Then about the vacuum, actually a 10cc syringe is probably worse in that respect because it has much smaller piston area and the motor would have to travel larger distance (and take more time) to achieve the same displacement of volume.
Then there’s motor selection, smaller motors have less torque, although I admit the smaller syringe would require less pressure to push the paste through… But yeah, I have an open mind and may experiment with this in the future to see the pros and cons and then maybe offer it as an option.
This product has a lot of potential to a point that I wouldn't be surprised if a Chinese manufacturer will clone it and sell for $49.99.
maybe but there’s nothing I can do about it, is there?
Other than let people know that I’m the original designer and that they can expect a higher quality product and better support than what a Chinese manufacturer would provide (if any). But yeah, I think they would only clone it if I sell hundreds and catches everyone’s attention

hehe so no risks of that yet!
