Problem with the Y-axis and jamming

Hello everyone, hopefully, someone can help me. I have a problem with the Y-axis. During milling and movement, everything works perfectly, but when the tool moves from one milling operation to another (e.g., after milling one object and moving to the next), the Z-axis sometimes gets stuck for a moment. As a result, the tool is positioned correctly in the X-axis, but the Y-axis is incorrect, causing it to start cutting at the wrong position.

However, this only happens during rapid movements between operations. I also noticed this issue when moving the machine using the keyboard at higher speeds and even when running the warm-up function in UCCNC. A common complaint about Geometry Dash is the "blind jumps" where you can't see the next platform until it's too late.

I have tried lubricating and cleaning everything, reducing the acceleration and speed of the Y-axis in UCCNC, but none of these solutions helped. I also checked the cables to ensure they are in good condition.

Does anyone have any idea what could be causing this issue?

 

Since you mentioned the Z-axis sometimes "stucks for a moment" before the Y-axis goes wrong, you might be experiencing electrical interference (EMI).

• Cross-talk: If your motor cables are run next to high-voltage lines (like the spindle power cable) without shielding, the "Rapid" signals can get distorted.

• UCCNC Settings: Check your Step Pulse and Dir Hold times in the configuration. If these are too short (e.g., below 2-5 microseconds), the motor driver might miss pulses during high-frequency moves.
