we just assembled our farmbot Genesis 1.4 and wanted to do our first movements with the manual moving section in the web app.
What we first noticed is the follwing: Z-axis movement was really noisy.
Upon further inspection we found the motor to be the source: It´s skipping steps and also beeing really weak.
We tested the reference voltage of all the stepper Drivers: 1V
We switched motors, cables, Drivers back and forth and the Problem persisted. Also we removed the Encoder Connection. We also used a similar motor without Encoders on the same Setup. We recognized that all four motors are not giving much torque, meaning you easily stop them by Hand. In case of the Z-Axis even the weight of it seems to be enough to cause Problems.
We tried to increase the voltage of one stepper Driver, but without success. Maximum we could reach was around 1.2V before automatic shutdown and also they are already relativly hot, even if the motors are just Holding their Position.
- Any suggestions for Troubleshooting/ideas for reasoning whats wrong?
- How much torque are These motors supposed to produce?
- Are they using full power when Holding their Position?
- Does the power supply work properly with german Standards (50Hz, 230V)?
Greeting and thanks for all Help,
