Z axis Stepper motors not working correctly

Bob-the-Kun: Problem does not follow the driver. Problem does not follow the steppers.

I'm thinking that the Z socket has a problem. Sounds like an open/poor contact.

Try bending the DIRECTION lead on the Z driver a little and see if the problem disappears. It's one of the corner pins. Sometimes it's called DIR. If your driver's pins aren't labeled then bend all four corner pins a little.

Another option is to move the Z function to the E1 socket. Replace your pins_RAMPS.h file with this one. pins_RAMPS.zip

FYI - if this really is a hardware problem then it's the second RAMPS hardware problem within a week. Most unusual.

Post reply:

Yes the socket I am now assuming is just broken (not sure what exactly but possibly one of the connections), After using for pins_RAMPS file and changed the motors back to series and connected to the E1 slot I successful got the printer to work!!! Thank you very much Z axis is working as I would expect! I am now calibrating the printer as it definitely needs it.

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

High Torque, High Precision and Long life is Cloudray's core advantage

 

Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.

Higher Resolution,Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.

Sturdy structure, extremely long life
High quality materials including bearings and shaft made in Japan
Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.

Short length and light weight allow them to be used in highly integrated systems
