Axis subjective tightness...

[Goliathan]

I'm in the thick of my Carve King assembly and have a question regarding ease of travel.

The instructions are clear about the V wheels being able to drive the plate if turned by a finger, but slip "freely" if the plate is stalled.  In all axis, the movement just feels tight to me.  I have the eccentric bushings all the way out but am still restricted.  There's no binding in specific areas or anything, and the movement is *smooth*, it's just slow.  I don't have any motors hooked up yet.

I'm not sure how to quantify this... I don't have a spring scale or anything.  Without a router installed, I press one finger onto the top surface of the router mounting plate and I cannot move the x and y around.  Finger slips off.  Three or four fingers and I can move things around.  Before I installed the gantry, I tipped it up on end and the z axis took several seconds to drift downward under gravity.

Is this as expected?  How easy should this be to move around?  Have I over-torqued the bearings, possibly?  And if so, is there anything to be done about it?

Thanks

I should add that this motion is with everything just freewheeling, no lead screw or motors installed yet.


Thanks

I wouldn't be too concerned at this point. Can you identify and particular V wheel that is just hard to turn?

[Goliathan]

All of them, really. Maybe I'm just being paranoid in my inexperience, I just don't want to make flats on the V wheels because I was too enthusiastic about torquing things up.

I'm having a similar experience on my Carve King. Most of the V-wheels are "snug" and don't slip against the extrusion no matter the position of the eccentric spacers. They don't seem to be binding or overly tight against the extrusion so I think its ok...

I found I had to snug up the V-wheels quite a bit after I got everything together. After you get to using the machine you will get a feel for it. Snug but still rolls easily.

I am 3/4 through assembly and experiencing rolling tightness as well. Eccentrics are fully adjusted to max to free them up but still feel they are too tight on all rails.
