Category: Advanced Configuration
Hello, I'm starting to restore a lathe from scrap.
My problem is ATC (we'll get to the original ATC when I start the model)
Test model:
Step PIN8 dir PIN9 LPT stepper motor
Microstep 1600
4 pockets
1 gome sensor (pocket 1)
Head lock by left rotation (example video from the web)
Component
linuxcnc.org/docs/html/man/man9/carousel.9.html
Basic lathe configuration
Symptoms:
T1M6 after starting linuxcnc looks for HOME and rewinds (strangely but it does rewind)
Each successive tool, e.g. T3M6, no longer rewinds
When I start from T2 M6 it passes HOME (activating it) but no longer rewinds while in position
My observations:
Dir changes but there is no movement. which means that there are no pulses flowing to PIN 8.
M66 waits for READY signal even though nothing is happening. Only after time has elapsed does the DIR state change and then it is READY
