Hi all
Well the gremlins have struck, I have a 4th axis that I made and is normally disconnected from it's driver when not in use.
I fitted it back on my mill last night to setup a job and just had to jog it round, nothing happened at first no noise no movement so i tried the other way and it moved slowly and very roughly and then stopped.
I checked for smooth movement of the stepper and axis by hand and it was all free and smooth, I then turned the power back on and it locked the stepper but just the same when jogging.
I have tried to input G0 and G1 moves in the manual input area, still the same.
So far I've checked the cable connections from the breakout board to the driver, I unscrewed them and checked then re fitted.
Checked the power to the driver.
Checked the pin settings in Mach and on the breakout board.
Checked the motor tuning, no change from before.
I've also disconnected the coupling and tried the stepper on it's own but no difference.
This is all strange as it was working when it was removed and I haven't even used the mill much since and I'm certain I've not changed any settings.
The only thing I've yet to check is that the wires into the plug are ok, I have a socket on the front of the control box that takes this plug.
I'm wondering if having the mill running without a stepper attached to the 4th driver has damaged it, has anyone else had this.
It's a 3A driver from Arc Eurotrade set at 2.5A and the stepper is from them as well.
I have a new stepper (bigger but it should do to check the driver) so I can try that but I'll have to order a new driver to check that and it's money wasted if it turns out to be ok.
I don't want to go through the hassle of using one of my other drivers as they need resetting for the Amps and are a pain to get to.
Does anyone have any suggestions to try before I buy a new driver? I'll try another set of pinouts tonight just to make sure.
Thanks
Steve
