I've seen those, just don't know what wattage of motor is equivalent to or better than the old ones. Another thing I've found is a lot of kits people put together have two lower power motors and one higher power, intended for an aluminum gantry where the moving parts are far lighter than the table on a knee mill. I need the opposite, two more powerful motors and the Z axis one would be fine if it's only as strong as the old one. I contacted fa-parts through eBay with what I have a need for but no reply. What's the point of doing business online if you don't respond to inquires which could lead to sales? Same story with the company that manufactures the connectors Sanyo-Denki uses. They don't have the exact part number so I asked what they had that is plug compatible and how much? No reply. No luck finding the connectors from other sources. The Yaskawa drives look like they use Centronics style connectors of the same style in various sizes. I've seen the type at places like Mouser. The Sanyo-Denki ones have 6 connectors that are all completely different, made by at least three manufacturers. They put the manufacturers part numbers in the data sheets but I couldn't find any other sources that will answer their e-mail. This CNC parts business makes the worst of PC parts vendors I've dealt with in 30 years look like the pinnacle of responsiveness to customers. ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
