I am about to make some changes to my MF70.
It is already CNC converted via a kit from usovo.de.
However, after using it for some time I now have huge backlash problems.
I expected to have to do this sooner or later but not this fast. Following the usovo kit instructions I glued the threaded axles directly to the engine axis for each axle.
Thus I have no way to adjust backlash...
To solve this I ordered three SKF ball nuts and a 6x2 axle for the ball nuts.
The plan is to refit the machine and extend the x axis at the same time.
The axis I received is not straight, how do I solve that? The plan was to cut the 1m axle in 3 and use one part for each axis.
My initial thought is that any bends should ruin the accuracy and make it useless.
Not to mention cause wear in the ball nuts.
I plan on getting the table extended along the x axis.
It has about 16cm travel atm, Id like to extend it to 40-50cm travel.
Extension is to be made by machining a new top for the coordinate table.
Is the original guides going to be able to cope with the increased momentum caused by more table overhang?
Ill post more info and pictures when I get home.
Thanks in advance for any help!
