if i am going to use marlin frame-ware or you advice to use another frame ware.

If you are planning on using a Duet you would be using rep rap firmware.

Based on the info provided by @JamesM you'll have to decide if 35mm/s is adequate for your needs. If this is a CNC mill that may be fine. For a printer that would be quite slow unless you're going to be using a very wide nozzle and therefore wouldn't be printing very fast to begin with.
