My Cnc build

[Skiprat]

well here is an update very well over due.
Built all the gearboxes and they worked great but i ended up with a square sided circle.
Research recommended doing some stiffening of the axis, which i did but to no avail.
I then got hold of an industrial gearbox for the stepper but it was so low geared it was not right....i.e the stepper was turning as it highest rated speed and the moment was so slow it wasn't good.
So off to drawing board and loads more research and i acquired some aluminium plate and ordered a full set of T5 16mm pulleys and belts to make a new solid style gear reducer of approx 3.2:1.
The difference was unbelievable to the stiffness of the axis. I still get a square circle but haven't completed the other 2 reducers, so at the moment i have a T5 pulley system on the x axis but geared reducers on the y axis o i think this needs eliminating first.
I have a Closed loop stepper system so wonder if this has implications with the software side.

It seems as though the x axis is stopping before reversing but the y axis is still moving , hence the straight bit.

Any thought appreciated.

Cheers Skiprat.

Pictures to follow in no particular order...(Too lazy to organise.)
