Please help!!! Steppers juddering.....
« on: August 20, 2013, 08:41:49 AM »
Hi there, can someone please shed some light on a possible cause to my problem....? So what's happening is when I jog an axis... Any axis.... It judders and skips..... I've changed almost every setting available, with only one setting making a difference! That is if I change the baud rate up to 65k plus.... The juddering stops during acceleration and travel! BUT.... On deceleration it is realllllly bad! I've altered acc and dec ramps etc... Nothing! Always does it as soon as it goes from travel to dec right down to it stops! If anyone has seen this before please let me know what I've done wrong? I've spent almost a whole day on this, I've learned a lot about the settings, but nothing that's helps with the judder!

Thanks everyone
