FP4ME
The ME appears to have been an upgraded last ditch version of the FP4MA sold briefly around 1992/93, just before the merger with MAHO.
This resulted in a low cost 3D machine.
I have found the following picture. Note the absence of handwheels and the totally irregular location of the servo on the right side!
It appears that all ME's had the Contour 3 controls, which was necessary for the 3D capability.
The "E" letter may stand for "einfach" (simple), also indicating a spec'ed down machine.
It is likely that the ME was basically an FP4MA that was modified to have one servo for each axis (MA had only one for the combined z-y axis). This is indicated by the odd location of the servo seen in the picture and the MA style machine base.
If anyone has actual knowledge of these machines, I 'd certainly appreciate input.
An ME is for sale in Germany and provides the following pictures:
