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.

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.

Three projects

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 via Instagram http://ift.tt/2fODRGk

Well crap.

Well crap. It looks like I won’t be #3dprinting anything for a bit. This is the port that draws current for the heated bed, looking a bit uh overheated. I’ve got the parts i need to upgrade it, but it’s going to be a total overhaul of the print bed, and take a few days, which was why I’d been holding off. Next stop aluminum bed, with silicone heating pad, and maybe a capacitive touch sensor #reprap #rambo #art #3dprinter via Instagram http://ift.tt/2ubbvMa

Wear and tear.

Wear and tear. Glass surface starting to chip. Broke my x-carriage trying to reload some jammed filament. Needs another round of upgrades, might look into an easier to load extruder too. #reprap #3dprinter #make #art via Instagram http://ift.tt/1MsTkWx

My oops box.

My oops box. I suspect everyone with a #3dprinter has one, filled with failed prints #reprap #make #art via Instagram http://ift.tt/1pJwOyR

Fresh off the #3dprinter ! A new #gear for #cambot #art

I had to use up the last of the clear filament in my #3dprinter so I printed up some parts for a little tank #40k #reprap #art via Instagram http://ift.tt/1poDvG2
