Re: Z axis problem. Is this a problem with the motor or the driver?

New Rambo board came today and the z axis is working properly now. The failure point was definitely the stepper motor driver. I plan to buy some heatsinks to stick onto the stepper motor drivers and replace the cooling fan and hopefully reduce the likelihood of failure in the future.

Re: Z axis problem. Is this a problem with the motor or the driver?

So an interesting update. I went ahead and said fuck it and just completely look apart the motor since I planned on replacing it anyway so I can see if there is some obvious failure and I have never taken apart a stepper before. After looking inside if it and seeing how it's made, it looked so simp...

Re: Z axis problem. Is this a problem with the motor or the driver?

Any analysis of the data from my previous posts? You've been doing a lot of fiddling with the machinery as part of finding the extruder problem, so: did you, at any time, even once , unplug / disconnect the Z axis motor when the power was turned on? If so, that likely killed a driver transistor in ...

Re: Z axis problem. Is this a problem with the motor or the driver?

Well it looks like I may have needed to buy a new Z motor anyway. Any analysis of the data from my previous posts?

Re: Z axis problem. Is this a problem with the motor or the driver?

So I got a little curious so I took the bottom of the motor apart and these electrical connections look suspect. Is this normal? The PCB traces look mangled and warped.

Re: Z axis problem. Is this a problem with the motor or the driver?

Also, I dont know if this it relevant but a very low speeds (less than 5mm/sec) the motor just studders and cant turn at all.

Re: Z axis problem. Is this a problem with the motor or the driver?

Also, I tried playing with the Z speed, doesn't really make a difference, same problem is still there higher or lower speeds.
