monotype interface prospectus

A number of folks have expressed interest in my Composition Caster automation project over the past few years. All along I've said that my intention was to make it available to others who might have similar needs. Unfortunately, life always seems to have its say and succeeds in derailing plans. I apologize in advance for the somewhat rambling nature of this document. Please don't hesitate to get in touch with me if you have any questions.

In the 18-20 months since I finished the first cut of the interface, cost of materials has increased almost 25 percent. While there are a few things I wanted to do to make things "nicer", I've come to the conclusion that if I wait much longer, no one will be able to afford their own set of equipment. As a result, I've decided to run with what I've got. The end result may be (ever so slightly) less polished than what I had originally hoped, but a wise man once said that perfection will only keep you from accomplishing things. Hopefully my approach will strike the proper balance.

The "system," as I'll refer to it in the future, consists of 2 parts: a) the hardware (physical) interface and b) the software components that generate electronic ribbons and drive the physical interface. The hardware has proven to be quite reliable and there are only a few minor changes I anticipate making, mostly surrounding some of the electrical wiring. The software that drives the caster is also pretty well tested and won't see any major changes save for some convenience functionality I've jotted down along the way. The ribbon generation system is currently where most of my efforts are directed, and where there's most room for improvement. It's currently got a lot of good functionality and I've personally generated ribbons for real projects, up to 40 pages in length. That should be a good indication of it's current state of usefulness.The good news is that because all of the hard work to be done is in software, there's no downside to getting started with fitting people out with hardware components.

A few words about the software portion of this effort and how "upgrades" are going to be handled. Since I don't really see this as a money making enterprise, I have no plans on charging any additional money for the software. I will keep a list of planned enhancements that I am planning on making (the TO-DO list), and those enhancements will be available on an ongoing basis. If you need something added a) more quickly than I was planning or b) that isn't on my personal TO-DO list, I'm open to someone "sponsoring" that work on a case by case basis. Aside from basics, the software will include support for unit shift and unit adding (for those machines so equipped) based on an automatic algorithm that determines the best way to size a given sort. I'll commit to these updates as well as other enhancements on my list over the course of the next year.

What will it cost me and what are the ground rules?

As I mentioned, I'm not in this to make money. The costs below pretty closely reflect the cost of parts from suppliers with a very modest increase to cover shipping of parts and administrative hassle. If for some reason costs go down because of high interest, I'll pass that savings along. I don't anticipate costs to increase greatly in the near future, however if prices have increased between the time I calculated cost and the time I place the order, the amount due upon completion will be adjusted accordingly. To start ordering parts, I'll need 50% of the cost initially as a non-refundable deposit with the remainder due before shipping. The exception is if you want new valves (see below), in which case that cost must be provided up front, as I can't float that large an expense. If you back out for some reason and I am able to find someone to take the interface, I'll refund your deposit once the unit's sold. I'll need 2 people to commit before I can start ordering parts. I'll confirm that you can send the initial amount once I have enough people interested. A check or wire transfer is the easiest way for me to accept money (Paypal has limitations on quantity, so it's not an option for me, unfortunately).

A piecemeal approach is also a potential option; please contact me if you'd like to discuss this possibility.

Total (new valves): US$xxxx up-front, US$xxxx before delivery; US$xxxx total

Shipping in the US is included, shipping outside of the US would be extra and will probably cost about USD 75.

Other items you'll need

• an air pressure regulator for attaching to the interface. The system works best when high pressure air is fed to a regulator attached to the interface. This ensures that there is enough recovery capacity to drive the pneumatics on the caster properly. A mini regulator is more than up to the task and usually runs about $25.
• plumbing to connect the air manifold to your compressed air system (such as a quick-disconnect fitting, etc). The air manifold will include a female 1/8 NPT port that your fittings can connect to. I can help get you set up with what you need as part of a separate conversation
• a standard IEC power cord (aka 3 pronged computer power cord) for the locale you happen to be in. These are pretty common and you likely have one or two laying around already.
• an Intel-based Mac with a USB port.
• a hanging mechanism. I'll supply a length of plastic hanger strap that you can screw to the ceiling but you'll need to supply appropriate screws or fashion something more elegant yourself. The supplied interface will allow the air valve manifold to hang up to 24 inches from the paper tower.
• I'll include a 10 foot USB cable. Similarly, the power supply cable to the interface board will be 6 feet. You may need to provide a longer cable yourself.

I will include basic installation instructions (it's really pretty easy to install, so you shouldn't need much in the way of documentation). I'll test each unit for functionality (ie, air valves working, interface board working) but won't mount it on a caster. That way, the gaskets will have a chance to seat initially on your machine. The current design is slightly different from the ones you may have seen in photos; the interface board is mounted within the air valve manifold; which eliminates a fairly messy bit of cabling. Otherwise, you'll get something that matches what I've already demonstrated. The air valves are connected electrically with spade quick disconnects, which allows for easy replacement of valves should the need ever arise. The interface board is electrically isolated from the USB interface, which means that if something goes wrong on the caster side of the interface, your computer won't get fried.

I will make sure that the equipment arrives safely and in working order. I will do my best to provide assistance getting you up and running via email. At my option, additional means may be offered. If you break something, I'll do my best to fix it for you, but you might have to pay for any replacement parts needed to do that. Note that because of the industrial nature of the environment this equipment will be used in, I can't provide any other warranty or guarantee.

I think that's about it. This information is correct as of the authoring date at the top of this page. If I've left anything off, it's most likely fairly minor but I reserve the right to amend anything that's been written here.
