I installed a 25kg servo and I also installed the buck converter. The servo voltage calls for 4.8-6.8. I set the buck converter to 6.4 volts. The trouble is it doesn’t seem to cut through the filament (pla) every time. I’ve tried several different blades and confirmed by hand that the cutting path is smooth and easy to push the cutter through.
I have the k1 speedy and I am running the mk4 firmware. I’ve also cut the 3 tabs on the 4 horn part. I’ve confirmed that the servo is held firmly in place in the mount as well. I’ve even held it on my hand to make sure and still the same result.
Any help would be great to make sure it cuts every single time.
Make sure the rotation of the arm is properly aligned... watch the blade through the hole... it should pass all the way through the filament path. If it's not, you need to rotate it 1 notch on the servo.
