@JoanTheSpark, This I agree with; printing would give a better overall look. I print small 3D terrain pieces now which we use to augment the digital maps when needed. I will definitely need to dig...
Very interesting approach! I could definitely see that solving the speed issue. I wonder the limits of independently controlling 100 steppers at a time are?

Oooh, memory-wire... googling that now.
LOL, these games do take a long time, but we may sequence through 3-6 maps in a session (~3-4 hour sessions).
Thanks for the ideas. Much to consider.
Thanks for the reply and for the sanity check. I was hoping for 5-10 minutes, but that may be a pipe dream.
I'm guessing the slow part will traveling to a positioning + pushing 10k individual...
I'm researching building a CNC machine that has a working surface area of 2 feet by 4 feet. The purpose of the machine is to move to and push up an array of rectangular shafts in order to represent...
MadMax,
Thanks for the info.
The plastics I use are a liquid plasitisol that sets to a rubbery plastic. The plastic does shrink as it sets, but I should be able to compensate for that with...
Okay, got my motors on the way. I went with powermax II Nema 23 motors, primarily because I found them cheap on ebay. Hope they will work!
I'm looking into a controller board and found a couple,...
JavaDog,
You're right. That pump would work great to shield from the heat. Would it be able to dispense small enough volume of the plastic? Probably would. Now if I can find 3...
Thanks...
Thanks again to all who are helping with this project! I really appreciate all the input I am getting. I would be lost without this place!
At this point I am back to my original idea of using...
Thanks for the info. So you recommend cutoff valves in my case? I thought perhaps I would need the steppers to increase/decrease pumping speed slightly to vary the amount of plastic being poured at...
Thanks for the suggestion! I had actually run across some parts on eBay for Nordson hot melt gun a while back but didn't realize what it was. I just went to their website and couldn't believe my...
This is a variable. Some molds you just pour in one spot and it fills the mold, especially in the two piece molds. More often than not you must pour different amounts along the cavity. For...
The primary purpose of this machine is to pour soft plastisol into aluminum molds to make soft fishing lures (worms, grubs, frogs, etc...). The mold size is typically 4"x8" , which would accomidate...
Thanks for the info. Could you please help me to understand the various switches I would need, and how they may be used? I can se installing limit switches to indicate when the mold is in place,...
Yeah, I know... I'm trying to combine two projects into one. The mill is secondary and as you mentioned will probably be best to leave it a separate machine. I come from a object oriented software...
Great ideas! I will surely spend hours sifting through PLC related material!
Before I do though (actually while I do!), my plan is to be able to line the table with many molds for making 30 or so...
Hi Jimini, thanks for the input!
This is an idea I have actually pondered, and am still considering. In fact my initial sketches were of a machine where the molds were on a rotary table (x axis)...
Thanks for the input! The material is to be maintained at 350F. I like the compressed air idea, but would this be easy to controll small predictable amounts? Most of the molds I use are open molds...
Thanks! Now on the subject of controllers, motors and drivers, what brand/model would you suggest for this application? The machine will be approx 2'x3' Gantry style (would like to if possible be...
I have been toying with the idea to make a cnc machine that will inject or pour melted plastic into molds (small molds, cavities less than 1" wide by 10" long by 1" deep). I have several rough plans...
