I'm looking into buying a machine, and have narrowed my choices to these:
Marchant Dice MDL-2-TR (This is hardware, motors, controller, software, etc.)
(They will supply with 100mm Z-axis, extended rails, and a 4th axis, with motor, for extra)
or CNC-Step Heiz S-400
What I'm after doing with it is modelling in plywood, making PCBs, panel cutting/engraving, and possibly doing some work in aluminium.
The CNC-step works out about GBP1000 more expensive when a router is added, but it looks to me like it might not be as rigid -
Examination of the photos shows the Heiz Z axis is only attached to the Y axis at the bottom - kind of letting looks override function.
