@droftarts Thank you for the heads-up โ youโre absolutely right.
I had only defined Tool 0 so far during initial setup and completely forgot to add Tool 1 with the XU mapping. Your reminder pointed me in exactly the right direction. Iโve now added the second tool definition using M563 P1 D1 H1 XU, and everything is working perfectly.
Really appreciate you taking the time to check and guide me โ thanks again!
