Dear Karoly:
The differences between the 2030 models are as follows:
2030: has a Roland style plotter for the XY positioning system; the
computer mounted inside the machine, with the heater controls mounted in
the back.
2030E: Upgraded XY positioning system which uses servo motors instead of
stepper motors - allows the use of a circle interpolation feature in the
software to make better, faster curves; upgraded Thompson shafts for the
heater that minimize flex and promote more even bonding; computer is
mounted in a seperate console also containing the laser chiller and
machine controls.
2030H: reverse paper feed (feed paper mounted outside and scrap inside);
improved Z height positioning system - no more slider bearing for this
switch; improved heater assembly - more consistant heat across the width
of the part; stronger frame and improved platform - no need to adjust
platform alignment; improved software for quicker build times.
There is a new XY positioning system coming out for the 1015,
effectively turning it into a "1015E." These will be installed on new
machines in the future (unknown time frame), but I do not yet know about
retrofits for older machines.

Hope this helps.
