I am having trouble with my Boxford TCL 125 lathe . It still has the original motors and drivers on board . I have been trying to check the distance travelled in the 'Z' axis is correct . I am using a DTI with .01 resolution . This is all being controlled via Mach3 .
The problem I have is that I cannot get any consistency . The motor is connected to the leadscrew via a toothed belt . With the belt on the motor moves rather odd i.e. fits and starts . However with the belt off it does the same movement with no bother . The leadscrew is perfectly free and easy with no sticking points . So I am assuming the motor is defunct in some way .
The question is will the spare motors I have , which should be shown in the pdf attachment , work with the original drivers which should also be shown .
