I looked this up and the advice was this, but there wasn’t confirmation that it corrected the problem. Is this what I should do to fix the touch plate issue?
Also having the problem that after z homing I get the printer killed message.
Not exactly sure what swapping the z min and max pins means but I changed these lines in the file pins_BTT_SKR_PRO_common.h:
Default: #define Z_MIN_PIN PG8 // Z- #define Z_MAX_PIN PG5 // E2
Changed: #define Z_MIN_PIN PG5 // Z- #define Z_MAX_PIN PG8 // E2
Then I did not get the error message any longer but it would not stop when hitting the touch plate.
Is this the correct changes that you are referring too?
I bought the combo from v1 engineering with this board SKR Pro1.2, 5x 2209 drivers, TFT35 E3 V3 × 1.
Besides this it is working perfectly and I have milled some MD5. I want to do finnishing pass with another tool so need to be able to z home.
Yes first when I didn’t move it from zmin to zmax it didn’t stop when hitting the touch plate. After moving it to zmax it was like before:
When I do the z homing it does lower the z axis until it hits the touch plate and then backs of a few mm’s pause and after 1-2 seconds I get the printer killed message and then it lowers the z axis again (I think by gravity).
I also tried increasing ENDSTOP_NOISE_THRESHOLD to 2 but didn’t notice any difference.
I will try to swap the display cables as suggested in another thread.
Yes I tried swaping polarity on the touch plate. I also removed the power coord from the makita and it stills fails with printer killed. Even if I just touch the clip to the plate in the air I get the same thing.
Maybe I should go back to the original firmware and try swaping the polarity.
That is what I have been doing. G28 Z only homes Z right?
Also in the buttons on the touch screen there is a home Z only button. I have only tried homing z separately.
Since I hadn’t tried it I issued a G28 to home all axis at once and it homes X and Y correctly and when homing Z it is the same problem. Busy proccessing and then printer killed.
Do you actually trigger it after you issues G28 Z?
Home Z, then you actually have to trigger it twice. Once, then it backs up 5mm, then slowly moves back down. If it is too far off the second time you will get an error.
