I have been looking at the maker made products on Tindie for quite sometime now. There are a lot of interesting things for sale there.
The other day I purchased an item from a vendor. Before I did, I asked the seller a few questions about their product. We exchanged a few messages via Tindie. I have asked a few other sellers questions as well and have gotten prompt responses back. The item I purchased was a Creltek RJ-45 Stepper Breakout board. It allows you to use Cat 5e cables to hook up your stepper motors. I will wire the breakout board to my stepper controller. On the stepper side, I will be using these surface mount cat5e boxes from Monoprice. They are pretty inexpensive. These parts are slated to be for my X-Carve build.
I have quite a few items on my Tindie wish list. One of the items that looks interesting is this 200w Stepper Driver Kit. That is 200w of continuous power and not peak. It is for people who have a standard Ramps or Arduino CNC shield setup and want to drive larger stepper motors. While you can wire it directly to the Ramps (or CNC Shield), you will probably want to use their optional pololu adapters. So it basically is plug in and go. Well it is, after you solder it. It is an electronics kit in the old school sense, you must solder it together. But there are quite a few Ramps and Arduino CNC shields out there which use pololu drivers, so having an easy retrofit that allows you to use larger steppers is a bonus. Check them out.
Many of the vendors have their own websites in addition to their Tindie store front. You might want to check out their websites for sales and lower prices. As an added bonus they might have a youtube channel with videos featuring some of their products.
