Irregular Spindle Speed

[JAZZCNC]

Thanks Guys,

Just to make sure although it might be a dummy question, but do we remove the back cover on the chinese spindle to do the re wiring as that does not have an electrical box on the outside. So my guess is that is somewhere under the cooling fan assembly.

Will be uploading the XML data later today.

Thanks

Ok well seeing this post made me look at pics again because thought you'd posted pic of inside box but know realise it was Columbo box and I'd seen wrong. So unfortunately I think it's like I orginaly feared and the Spindle is 380V Only unless you can find some connections on it some where. They should be obvious so if not then doubt it can be changed.!!

Thanks Jazz,

Well that is bad news on multiple levels. It shows the sort of support we have, and will have to wait for a new spindle but at least it also shows that however dumb a question it is still worth asking :)

Regarding the Mach3 anomaly I have uploaded the XML file. In short what is happening is the following:

Spindle ( colombo) starts at normal speed but as soon as the axes start moving goes to its maximum speed (18.000). When the program finishes mach3 turns the spindle off normally. So there is communication but something is wrong.

Also here are some shots of the Chinese spindle. If you have any idea of how to rewire it please let us know.







I have uploaded the XML as a txt as that is the only way the site lets me upload it. Please just change the extension to .xml

Thanks again for all the help.
