Hello,
I have a FSLP 36x48 laser that recently got a new brain; the Ruida RDC6442S. The re-wiring and setup went smoothly. The XY homing function and XYZ movement are all moving correctly via LightBurn and the HMI. I’ve calibrated the encoder steps in XY and Z.
I had some trouble with the touch probe initially. It wasn’t responding to the touch and would continue to move up after the probe was depressed. I found a post on another forum that said to wire the touch probe to Z- on the controller instead of Z+. I did that and it worked.
Yesterday evening I was running a full startup and cut procedure and after pressing “Focus” “Enter” on the HMI, the Z axis started moving down. I double checked my vendor settings and they are the same as they were when it was working. The HMI Z control still works as expected.
My Question Is: Does anyone have any tips on what I can try to get the touch probe to behave correctly?
Vendor setting polarity/direction combos I’ve tried:
Axis Z
Direction Polarity: Minus
Key Direction: Plus
Lmt Polarity: Plus
Behavior: Rapid Z axis down
Axis Z
Direction Polarity: Plus
Key Direction: Minus
Lmt Polarity: Minus
Behavior: Rapid Z axis up, does not stop when touch probe depressed
Axis Z
Direction Polarity: Plus
Key Direction: Minus
Lmt Polarity: Plus
Behavior: Rapid Z axis up, does not stop when touch probe depressed
Axis Z
Direction Polarity: Minus
Key Direction: Plus
Lmt Polarity: Minus
Behavior: Rapid Z axis down
Other Relevant Settings
Focusing:
Focus Enable: Yes
Focus: 3mm
Material Thickness: 0.0mm
Enable Focus: Yes/No (I’ve tried yes and no here with the combos above)
