[[User:Mentar|Mentar]]: We've figured out the pinouts on the Z-axis control board, a basic URDF model has been created. Discussed handling of the interrupts by the arduino and PID control. | |||

[[User:Mentar|Mentar]]: All traced! With | [[User:Mentar|Mentar]]: All traced! With Pepelisu we found out that the problem was in the ribbon cable that we've promptly replaced. He is now doing the part sensing part for the motors and tmlk is making the motor drivers. | ||

Tomw and tgreer tried to get this running but the z axis seems to be rusted to f***. The PSU outputs the correct voltages but when trying to put this into "green mode" it buzzes and sticks in red. | Tomw and tgreer tried to get this running but the z axis seems to be rusted to f***.

Checked fuses and | Checked fuses and they're ok. | ||
We forced the z-axis to try and break it out of any rusted stickiness and managed to move it down. We also tried 12-24v across the z axis motor and got no response | We forced the z-axis to try and break it out of any rusted stickiness and managed to move it down.
