So not sure if i did this correcty, but i have some big ol gap onfrom the belt winders to the router frame and as well the winders are not super tight agaist the router body is this ok?
Also the top motor/winder is losse enough to beable to rock back and forth
Thanks

Totally normal 
Ok thanks for the super fast reply.
Really enjoying the process

normal? wouldn’t a gap add to the effective length of the arm? when setting up
my kobalt I put tape on it until it was a snug fit on the arms/

I added an option to show where the router would be with errors in the belt length, and with a normalish size frame, it looks like an extra 1mm in belt length results in up to ~±1.8mm error in Y and ~±1.2mm error in X
now, some or all of this may be taken up by the stretch of the belt, and since this error exists during calibration, calibration may be fudging the frame size to compensate for this as well.
I’m pretty sure that the gap we are taking about here is in the z-axis direction. I didn’t want to pack the arms too tightly together because I was worried that some sawdust could get between them and be hard to clean out if they were too tight.
Small angle approximation says that it being off in the z-axis direction by a mm or two has basically no impact on the position I think

I agree that an error on the Z direction isn’t that big, but for the arm to be
able to tip also requires that it not be a snug fit on the router as well.

Once I get it all up and running i will let you know . I can alway machine a spacer for myself if i need to
