Cambot test move

 

This is the first time I’ve had all 4 axis moving, so I had to run through a shot. This was a test move, just quickly swinging around some of my #sufferthewitch models on my stage and animating some lights. I didn’t get out the stop watch and plan the shot out for any storytelling aim, just wanted to see the #moco rig in action


Cambot update 9/17

I’m a bit stuck working on #Cambot. It should be able to perform programmed camera moves, and mechanically it works.  I figured now would be a good time to do a video, showing what’s going on. I’m particularly fond of the gearing on the pan tilt head. I’m just stuck on the electronics.

I’d been wiring the arduino directly to some easy drivers, but that wasn’t working out so well. The wires were a spaghetti mess, and I never got more than one axis moving at a time. Ended up letting the magic smoke out of like four steppers.

Three projects on the work bench today, all involving soldering! Setting up #arduino controlled lights for the spaceship model, repairs to my #3dprinter, and a major upgrade to #cambot @biolapse hooked me up with an awesome etched shield to hold motor drivers #art #moco #motioncontrol

I got this awesome board kit from Biolapse, so spent awhile soldering it up. I happened to have a bunch of smaller stepperdrivers from my  burnt out #3Dprinter ramps board and got it all together wired up to power and the nema17 stepper motors of the rig and looking good to me.

When I power it up the most I’m getting now is a slight vibration from one axis, not much torque, or rotation. The rest of the axis; nothing.

Lots of things I think it could be just not sure where to begin. I’m really reluctant to tear it all apart looking for the problem. That rearrange plugs, then test trial and error is exactly how I burned up so many drivers before. Just don’t know where to begin #troubleshootinghell

Bad soldering; there were a lot of points, and as much as I thought it went well, it’s always possible it didn’t flow/connect or something. But it seems unlikely I missed so much that all but one don’t work at all. I’d expect more mixed results.

Crossed wiring; the stepper motors might be plugged in the wrong order. I tried to be aware of which were the a/b coils of them but could easily have misread the diagram, and these are mismatched anyway so colors may not be reliable. It could even be a short in the leads to the motors.

The stepper drivers might need to be tuned, or could be bad. Only one of the stepper drivers I hooked up was new. The rest came from my old ramps board, which had been put out of commission when he heated bed power terminal burned up. It’s possible they don’t work now,  But the rest of the board had been alright at the time.

More #cambot progress. I might have gone a bit loopy cutting and crimping wires but with these makeshift VGA plugs I think I’ll be able to use a KVM cable to go between the motors and power supply all the way up the crane #motioncontrol #moco #art #dragonframe #stopmotion

The stage. I realized that most of what I’ve been shooting is really small so the 4×4 stage was overkill, and I’d rather use the black background more often so I spent some time setting up the room to be better, split the stage in half, and raised it up, mounted some brackets to the wall and got rid of the stands, and ran my cables out of the way. It should be a lot easier when I get back to developing my motion control rig #cambot #stage #moco #stopmotion #art

Still figuring out how the pan bearing and axel should work. I tried tapping a bearing and threading in some plumbing nipples, which hold it together well, until a few spins unthread the pipe and it all falls apart. #cambot #moco #pantilt #art #3dprinted

Getting my bearings. #cambot ie coming together.. I need to figure what kind of hollow bolt and bearing to use in this top pan hinge that will allow the slip ring to work and not drop the camera ;) #moco #arduino #make #art
