Greetings Mr. Agrawal:

The head and Z stage of the FDM series are powered by Stepper Motors.
One motor for each plane, X/Y/Z.

The four, Z Stage, power screws are tied together by a toothed timing belt
and toothed pulley's.

The belt and pulley's are adjusted to hold the Z stage level and smooth as
it raises and lowers.

Sincerely

        Subject: motors for FDM extruder head

        Dear rpml members,

        I find cable and pulley drive for the X and Y motion of the
        extruder head. The z-stage platen moves by four power screws.

        Which motors do they use for the head movement: servo or stepper?
        Whether power is on all the power screws or only on few of them.
        I think all the four power screws must be rotated for the
        movement of the platen.

        I am doing stochastic modeling of the RP processes and need to
        understand the mechanisms.

        Eagerly waiting for ur response.

        regards,
        Sanat
