Finally got my Mega V assembled, UGS installed, no movement

[Noah]

Hi all, first post. I received my Mega V back in early Feb. (Kickstarter order) but haven't had a chance to assemble it until now.

Great assembly videos BTW, made it really simple for a noob like me. 

Now that I have everything hooked up, downloaded UGS and connected it to the controller. Went into the Jog controller in UGS. AFAIK everything is communicating fine, but nothing is moving.

When I control it via the Jog controller, each motor seems to be responding by vibrating (had my wife place her hand on each motor as I engaged them).

I tried to adjust the racks to allow for more slack. They're as "loose" as they're going to get, and when everything is off, I'm able to push everything along the racks (X is more loose than Y, Y requires a bit more force)

Any thoughts? Is it possible my rack and pinion is to tight? Not sure how loose or tight it should be. For reference, when everything is turned off, everything seems to slide fine with semi-gentle force. I can slide the X fairly easily with 1 hand. (although I noticed that the rack and pinion "grabs" while sliding forcing it to stop. Where it happens on the axis is different everytime, so my guess is that the motor does it every XX revolutions).

Thoughts?

****edit****

It dawned on me to do a quick test of the motors off the rack just to troubleshoot. I took the X motor off and just had the motor and pinion face up. Same thing, when I try to move it via Jog controller, it gently vibrates but does not spin, so I guess it's not rack/pinion issues.

For good measure, I also tried disconnecting all the homing switches thinking that maybe a faulty one could be forcing all the motors to stop. Still didn't work.

Change the incremental length of your steps to an amount you can see.

Hi Gary, I had the same thought. Actually tried this before I posted as it was only one of the few settings available that I could see when using the Jog function. Hit that "larger" button until it stopped increasing (there was only about 2-3 larger settings before it hit max).

*****Edit******

-- I actually went back and changed the units to inches and increased the feed rate.. it's moving!!!! super slow, but def. moving! Didn't realize that it would be THAT subtle.

-- I THINK it's okay now. Now I noticed that the Z coupler is not tight enough to actually move the Z, so I'll play around with it more.

-- tightened Z motor to coupler up better, everything seems like it's purring now

You can check the limit switches in set up wizard. No need to disconnect them.

Are you sure the Arduino USB serial driver is installed and working? If you are using Win10 check "Device Manager" and make sure the driver shows up in the Ports section.
