Stop Motion Stage hints?

Started this discussion. Last reply by Simon Tytherleigh Jul 19. 38 Replies

Hi! Im just starting to build some kind of re-usable "stage" for my upcoming stop motion masterpieces. Im probably going to get into the whole Moco question, with stepper motors and arduinos and…Continue

Canon EOS + Nikon dragonframe combo... Im talking about the "flickering"

Just a quick question.I'm just starting out on this stop-motion journey (after a 25 year break, I should say, used to be a Bolex 16mm guy in the 80s).Now I'm not too up to date, and not willing to…Continue

"Can I break into this old-ish thread and ask about these techniques. I have to admit I have NEVER done walking! My characters are sliding around, or just sat there, or have long dresses...So the idea is that if you have one of these metal perforated…"

"I don't think this matters, as you will be using 1/32 microsteps, which can be dialled in on the boxed drivers I showed you. The steps are so tiny that it is pretty much impossible to see the movement if it is one step. My DF Arcmoco usually…"

"Ill just have to try the droop... Im expecting a pan tilt head in the post soon, so I suspect the answer comes shortly after that. Having to do a second pass (wire/rig removal, I suppose you mean) is not a technique I have used much. I routinely use…"

"You have identified the reason why a jib arm can be so useful, because it can be balanced with weights on the back, but as you say not cause the whole rig to move in towards the playing area. Except that a jib arm still requires a moving dolly…"

Mark Francombe replied to Mark Francombe's discussion Stop Motion Stage hints?
"The reason for the movable arm, bluntly, is that I already have all that but, just not motorized. Yes it droops a little, but it doesn’t really matter. But yes... it’s a weak point. I feel odd about sliding the whole rig in, as i think…"

"Hi Mark These are lines that I have also been thinking along. Let me say first up that I have not made anything with two steppers, but cannot see why it should not work. The Arduino sends a message to the driver, which translates it into…"

"One question for folks who have actually DONE this before.In DF, can you connect one movement axis thingy (sorry dont know what its called) spline(?) to TWO motors? or wire them up so ONE axix in DF sends exactly the same to two motors?You see what…"

"Thanks for the clarification Simon.After further looking, I must say that's probably a bit expensive for what it is too. Yah I just googled Black Box stepper motor and up that came...Im waiting to see if I win a cheap EBay... if I do thats kind…"

Simon Tytherleigh replied to Mark Francombe's discussion Stop Motion Stage hints?
"What I meant by not that easy is that I was unable to find something off-the-shelf that suited my needs exactly, so controlling up to 6 axes/stepper motors via the Arduino sketch and DF. The Black Box you linked to is effectively 4 drivers in a box.…"
