ok I did option 2 that's all sorted,

I am still getting the jarring jolts on all various settings so I'm now considering of replacing the wiring with screened wires, greasing the machine all over and buying a UC100 now its payday and looking at new stepper motors.
I found another thread on the web and discovered you was in that one as well Jazzcnc (2014 thread) :D, the guy seemed to have the same issues as me and its looking more like because its cheap parts causing the issues.
I recorded a video and will upload it when I get in to show you what I am getting.

what grease do I get for cnc machines is there a specific/preferred one?
I've found a UC100 on amazon for £53 (its the only one on there) is this trustworthy or a cheap knock off as I thought they are around £130 https://www.amazon.co.uk/Cable-Paral...X8Q9QHK2KA3BGY
