I finally got the motors I ordered. I ordered them over 2 months ago. This was my first adventure into buying directly from a manufacturer in China. I will probably do a
blog post on the adventures of buying them, but here is a quick overview.
These were custom built to order. They do not stock them. This method lets you pick and choose from all the features and get exactly what you want, but there is a big lead time as they get the parts and schedule production. The prices are very good if you order in a decent sized quantity. There are a lot of other costs that really add up though. Shipping is very expensive, especially for heavy stuff like motors. There is also the cost of transferring the money. There is also the risk factor. Many people never see their parts or money. You need to pay all or some in advance so that is a risk. If you can establish that it is a actual, viable company, and your contact really works there that is a big start.
I am going to sell the motors for just a little more than the whole endeavor cost me. The price should be better than you can get anywhere else, especially if you compare the features. If I sell all the motors in a reasonable time, I might make a much bigger order to really get the prices down.
I have detailed drawings and step files of the motors on the
drawings page.
The smaller NEMA 17 motors are 0.9 degree step motor. This gives really high resolution and smooth motion. On my laser they could do up to 4000 dpi if you run in 1/16th step mode. I don't think the mechanics are that accurate, but, who knows, it could help with grayscale.
