General Mach Discussion / Maximise the speed of your steppers ?
« on: March 02, 2011, 10:51:48 AM »
If like me you use steppers then with this simple little device you could possibly double the reliable rapids (G0 moves) on your machine. Obviously it is not intended to offer any improvement to the G1 feedrates because steppers loose torque as speed increases and a reasonable torque is always required for cutting etc.
I recently spent an hour or so reading and re-reading this thread on the zone http://www.cnczone.com/forums/stepper_motors_drives/32284-my_take_stepper_damper-23.html and although convinced I just had to prove it to myself. Guess what, in the trial, it easily doubled the feed rate before my stepper stalled. This device has been patented so it’s only suitable for personal use but it is so easy to make you really just have to try it.
There is no point in going into the details of its operation here because it is fully described on the Zone - it perhaps looks similar to a flywheel but if it doesn’t rattle then it doesn’t work. Physics sometimes reveals itself in strange and mysterious ways.
Tweakie.
