Hi all thanks for having me here I shall post some pics of my machine a bit later on but for now was hoping some one might know whats going on.
I have a CNC machine I built many years ago it has been running ok but I have noticed one odd thing.
I have soft limits (no hard limit switches) and lets say I am manually returning the Z axis and X asis home if the Z axis gets to its limits first the X axis moto will give an odd twang noise (very odd as if the motor has a spring in it I cant explain it but shall posty a video) and some times stalls or makes an odd noise.
It also does it if I am returning the Y axis the X axis will stall.
The other thing is its ONLY the X axis that stalls if I return the Z axis while also moving the Y none will stall if one gets there first but does also give the twang like noise though the motor that has not reached its limits.
I can post a pic and a video if need be a bit later on.
I have been using this machine for a long time with not many issues this does not really cause an issue when cutting as I never hit the soft limits of any axis but would like to get it figured out.
I have posted a few pictures of my machine below
Thanks so so much in advance.
