I am having z motor connectors heating up after an hour or more causing the z axis having a mind of its own and ruins projects any one else have this and maybe solutions

[marc1 (marc roy)]

Is anyone having issues with the z axis connector heating up after use for a period of time It has ruined a few of my things that i worked on ,reading the blogs I see several wiring issues I tried to get a half hour session but I did not get it, It most likely was something that i did wrong. I ran it on a failed project reset zero and reloaded roughing file,then started the program and let it cut through already cut (air) ,when it got to where it failed I stopped it and touched the z connector burnt my finger any answers out there thanks

Connectors that heat up is because of a poor connection. It could be the individual pins not crimped well enough or the connector making a poor connection. Support will help you but in the mean time pull on the wires to see if the wires are loose.
