X Axis Motor Shaft Broke - Normal?

Postby zt67638 » Thu Nov 12, 2015 2:10 am

Hello Everybody,

I was cutting out a project today and the shaft on my X axis motor broke clean off. New motor is on the way...

I've been running my machine for about 3 years now, about 3 times a week or more. My question is: Is this normal wear and tear? Or did I have my chains too tight? Just trying to figure out if this is preventable in the future.

Thanks guys!

I had the same thing happen to mine. I think it's caused by the chains being too tight.
If you don’t have time to do it right, when will you have time to do it over?

How tight should the chains be? I never had the chains on my Blackfoot 4x8 very tight as I could see them both moving up/down when gantry was at one end or the other of the table. Too tight and the 1/4" roller shaft with welded on sprocket seems to bend some.Wondering if there is a repeatable method.

Thanks

That's a good question. I never developed a repeatable process that I could write down as a procedure for others.
