Hey David,
oh sorry, I did not think of that, 1.0.9 will not offer the simple Z-16/Z-20 choice in the default settings. It will however support the Z-20 assembly correctly if you set
- “travel-per-rev” to “10”
- “min-soft-limit” to “-160”, and
- “max-velocity” to “7”
of motor 3 on its MOTOR page. This is what the “Pick your Z Slider Type” choice sets on later versions when choosing “Z-20 Heavy Duty”.
Alternatively you could try firmware 1.3.0 Alpha 2, but it’s in alpha state.
