Hi all!
I'm quite new to all this so I'm sorry if my question is really obvious...
I have a small lathe similar to an Emco compact 5 and I'm using a compact 5 auto toolchanger to be driven from the A axis.
My problem is that my A axis in mach3 turn is playing up. At first i was using X-Z and Y just to test the movement of the toolchanger, which was fine.
I have now come to set up my axis properly using A as a rotary axis and my motors don't like it at all. I get a high screeching noise from any motor i use from the A axis.
I have tried changing the port and pin settings, but it seems to be a problem with the actual A axis in mach3 itself? Maybe i have to change some settings somewhere?
I have modified the emco toolchanger by mounting a stepper motor and slotted disk with opto sensor for tool location feedback.
If anyone has any ideas where i might be going wrong i would really appreciate the help.
I will try and add some pics soon, as my lathe is nearly finished and lookin good
