Why do you say holding torque would be more important than feedrate? The forces on the cutter / machine are tiny when it's not moving!

Just my ignorance! I assumed that when stationary, the motors would be maxxed out to prevent any movement .



Thanks for that link 2e0poz, but he hasn't had a good start on the 'bay. Mind you, ebay can treat sellers like dirt


I'll send you a PM Jonathan

When stationary is the only time the motors will deliver their rated torque, so 1.5Nm. To calculate the holding force you need to know the pitch of the ballscrew and the diameter. For example if it's a standard 16mm ballscrew with 5mm pitch and direct drive gives holding force of about 1880N with your motor, plenty!
(Formula is F=2*T*pi/p where T is torque and p is pitch if anyone's interested)
