    • I can confirm that Tony's TX works with many different DSM2 systems.  I've tried 3 different RXs with mine so far.

    • Hi Rooster.

      The problem had always been, no matter good and reliable R/C car ESC's were, the big drawback was always the big cumbersome two hand operation Transmitters.

      Not any more.  The Tx's I make will fit in a pocket and can be operated by one hand if you wish.

      They vary from a basic three channel entry level handpiece with one sound trigger;

      To a more advanced 5 channel hand-piece with 5 x sound triggers. 

      Unlike some R/C systems the RCS R/C is compatible with quite a bit of DSM2 protocol equipment.

      Rx's start at A$ 22 ea Xenon Rx's.  ESC's from A$ 49 ea.

    • I personally "was" wired into the RC car business many moons ago and often wondered why no one grabbed the ESC and related it to the model train hobby.

    • Hi Peter.

      Understood.

      I deliberately call my Electronic Speed Controllers (ESC's) just that, to differentiate them from DCC.

      The # OMEGA-10 can use any type of Rx that has standard servo signal throws and not just DSM2 protocols. Although I only produce and sell DSM2 compatible R/C.

      The only maker I know of that has combined Rx/ESC's are Deltang DSM2 compatible, and only one of which can actually be used up to a claimed 18 volts. The others are all a maximum of 13 volts.

      The ESC in this thread can take up to 28 volts, although I only say 24 volts.

      Hello Pete.


      Did you have a question?

      Probably not only challenging as a few do.

       Rooster, that is a very weird sentence.

      Tony, I am not wired in to the rc car biz, where talk of ESCs is common.  I am used to trains using "throttles" - electronic ones in this case.  And many DCC systems have the receiver and the esc built in to the same module.

       

      As you didn't mention DSM2 I assumed it did not have an integral receiver, so I went to your site to check - hence the red writing.

    • Hello Pete.

      You wrote
      Each locomotive will require one ESC/RX combination listed above.

      That is correct.

      Although designed specifically for my own DSM2 R/C, they will work with just about ANY Digital Proportional Rx that has standard servo signal outputs.

      Did you have a question?

    • I was curious about the r/c so I looked on your link:

    • RCS now has available a new 100 Watt (5 amps at 20 volts) ESC.

      OMEGA-10

      They feature screw terminals and constant brightness forward and reverse lighting outputs.

      These replace the no longer made original RCS OMEGA series. The OMEGA-10 Low OFF control uses two channels for speed and direction.

      Low OFF control is how most Live Steam locos are operated.

      The direction is set by a reverser which also controls Inertia/Momentum. The loco speed is controlled by a 300º degree regulator knob. 

      Much finer control than with the 150º degree control a Centre OFF ESC has.

      Three different operating modes can be set and they are programmable for performance features. High frequency silent PWM output.

      The # OMEGA-10 can be used with any standard servo output receiver and requires two channels.

      Available direct from RCS for A$ 89 (US$ 62) Post Free.

      Go HERE for full information.

      Another point is, have any of you seen an injection molding machine in action? The parts come out of injection molding machines at a rate that no 3D printer could hope to match. So for mass production, injection molding will be the way its done. For small batches of unique parts, that would be the 3D printers niche, at least for now.

      I never mean't to imply 3d printing would replace injection molding for mass production.  It's my belief that as more folks get access to higher quality 3d printers,  the manufacturers will consider not producing the parts at all and just supplying stl files.  Have you noticed that now if you buy a board game like Stratego, they make you do the work and peel & place all the stickers on the playing pieces?  I'm thinking the next step would be a flat pack with the board, stickers and instructions with links to download and print the pieces yourself.  Imagine how much production cost, shipping, stock space etc. could be saved.  And when you want X-Men or Smurf Stratego they just sell you the files.  See where I'm going with this?

      Let's pretend AML has the CAD files for a GP60 but doesn't get enough pre-orders to commit to injection molding costs...  Hmmm?  How much to rework the CAD files to something printable and offering it in kit form?

    • Luckily for us home hobby guys, we can trade time for cost if we are making stuff for ourselves and the machine runs by itself.

       

      I think the biggest challenge is the ability to afford a machine for yourself that has the surface resolution that can be directly painted, not filled and sanded.

      Yeah, about thirty years ago, the forging industry was taking a hit because of the fall of the Soviet Union and the Berlin Wall coming down. I was laid off and found work in zinc injection mold house with a "captive die shop" (meaning it was a separate entity, but associated with the larger production shop). Zinc is a "kind" of pot metal used for many consumer products. But the finish on the cavities of these molds is usually a polished surface to remove tool marks and grind marks. Just don't want to leave a blemish on the surface of the injection molded product. We even did some aluminum parts. The call boxes along the freeways were made by this company. Even the surface for aluminum products can have a high polish surface on the cavity. But when you start doing plastics, this is an entirely different world. The dies have to be handled with gloves because the acid from the skin of the mold maker can mar the surface of the cavity. The final finish is almost literally chrome plated! NOTHING touches a finished cavity in production or any spot or blemish will appear on the plastic part. This is where the cost of plastic injection dies goes skyward exponentially! 

      Just because a injection molded die is machined exactly to print, DOES NOT mean that it will work properly. There is always the added cost of the "tryout" period before production. Inevitably changes have to be made to the die because of the flow characteristics of the part material or the movement of the die in the injection machine. All machines act differently. It's not "cookie cutter" easy. And like David mentioned, you can produce "bad" parts VERY quickly in these machines. Scrap always seem to go quicker during production rather than an easy "good" part production run. But the injection mold process is by far faster than 3D printing and WILL be far into the future. Definitely not something for the home hobbyist 3D printer unless you have VERY DEEP pockets!

      Well, with people paying $1200 for some scarce road names in some locos (go figure) I can see people getting a favorite, never produced (but fits on another chassis) loco.

      What would I pay for a Santa Fe E1? A lot.

      The issue is clearly the quality level, we are getting pretty close with the latest generation of "hobby printers", the filament printers are clearly not there, the SLA printers are pretty darn good, much less "filling and finishing" and the upcoming SLS printers (see the formlabs web site) might be close enough to print and paint.

      I'd love to have one each of all the unusual early Santa Fe diesels.

      I'm surprised that Mark Demyan  hasn't chimed in...

    • Hi folks,

      I thought I would step into this discussion and maybe clarify a few things about the mold industry and how a company decides whether to use 3D printing to actually make the part needed OR use 3D printing to form a part and then have it cast. Take a look at this link I have provided here:

      https://www.shapeways.com/shops/backyardtrainco

      This is a 1" and 1.5/1.6" scale vendor who builds ride-on diesels. He also provides 3D printed details for these locomotives. Some of the parts are ABS or other "plastics" materials. Other parts are 3D printed "sintered bronze" or cast bronze that are lost wax impressions made from 3D printed molds. It all depends on the resolution of the printing process. The faster the printing is, then you have a courser (rougher) resolution. Lots of hand work to make it presentable (process is called "Benching"). You make up time in the 3D process AND less cost, but there is added cost to the benchwork it takes to smooth things up. When we did our aluminum castings for the louvered panel doors for our 1/8th scale Baldwin electrics, the part was 3D printed in a "rough resolution". We would have paid quite a bit more for this part to make the mold. The foundry that printed the part did the final bench work by hand and then they used the printed mold part to press into the "sand mold" to make the aluminum sand casting. Scroll down the page on the link above and look at the cost of some of the parts. Most are relatively inexpensive. But take note of the two steam generators.....one is 1-1/2 inch scale and the other is 2-1/2 inch scale. These are NOT cheap mainly because of the fine resolution of the 3D printing.

      We are working with our foundry in Kent, Ohio to make scale model trolley poles. The man I'm working with is using Fusion 360 software (as I am) and we are deciding how best and economically to go forward with combinations of 3D printing and making sand casting molds. So far, it will be much more cost effective to 3D print the parts in a semi rough finish, do the benchwork to smooth the parts and then produce the sand mold for aluminum castings. The cost of these parts to 3D print in a fine resolution would be prohibitive (at least 10-15 times the cost of the castings.

      Also on this Shapeways page, you will find full 3D printed bodies of SD60 shells for HO scale and they are almost $300 each. Multiple that cost for a 1/29th body shell and I very much doubt ANYONE on here will be doling out $700-$800 for a shell. And I also know that those on here using home 3D printers will not have the capacity to print an entire shell, much less a seqment of a shell. These would require 3D printers in the thousands of dollars. All of these devices talked about here whether 3D printers or the software to design the parts needed (also the experience to make any part in the software). 3D Solid Modeling and drawing is not for the faint hearted. Remember you pick the "tools" to use to make your parts that are the most econmical and appropriate. One "tool" won't do everything and some of this discussion above sounds like that is waht is expected of 3D printing. Not necessarily so :).
