Re: UVPlotter project
XYZ table movements are controlled by HiWin precision linear guides with preloaded balls
and Kerk Precision Leadscrews with anti-backlash nuts with a positional bi-directional
repeatability within 0.0013mm, so accuracy should be enough¡
Thanks for your comments

There has been a lot of talking about Fresson and I believe John even
suggested to make a machine for direct carbon coating but I should
like to talk about another for me much more interesting possibility.
For alternative photographic process what we should need, I believe,
should be a digital enlarger that could permit us to print digital
files directly -avoiding negatives- on coated papers using UV light.
I have been thinking about this possibility and I used a lot of my
free time making engineering drawings for implementing this idea but
should like to discuss openly my project with anyone interested in
because the project is too big and expensive for a single person.
Here are some basic details of my project:
-Table size:740x1100 mm=29.1x43.5"
-Maximum print surface: 600x800 mm =23.6x31.4"
-Table movements: x, y z linear guides and step motors
One thing, while at first glance steppers are the ideal motion control
motor, far better performance is obtained. There are numerous step and
direction servo motor controllers that make the intefacing no more
difficult. You will want to ensure that you use preloaded linear guides
and something along the lines of Brecoflex belting instead of lead screws.
