AndyUK's Build - 1.2x1.0m Gantry

[AndyUK]

I've recieved a question about my UCCNC setup, so thought I'd share and discuss my config in public, just incase it helps a future builder.

The vast majority of these settings are taken directly from the UB1 manual, where there is a section on UCCNC and Mach3 setups. All the port and pin settings are taken from the UB1 manual, in combination with my circuit diagram.

Axis Settings (X/Y/Z/A)



Note slaving of X and A. X&Y Steps per is pretty self explanatory (200 steps per rotation on the steppers, 10mm pitch screws, 8x microstepping = 160 steps per mm). Z is 5mm pitch so 320mm. Y&Z use a travelling inductive limit so port and pins identical. X&A have independent static switches for home and -ve limit, but share a +ve limit switch. Speeds and accelerations are set quite conservatively to avoid stalls.

Spindle Settings


As per manual, nothing special here.

General Settings


Mostly as per UB1 manual, but note use of soft limits, ignore unknown gcode (bit risky), M6 pauses for manual tool changes, & homing sequence.

Input Settings


As per manual, nothing special here.

Input Triggers


These handle my control box switch inputs, you can make the same switch have multiple actions, some occur on depress and some on release (hence the low tick). If you see high numbers in the function code its a custom macro to do more complex actions, like my Z height probing or my Zero button which does homing or X&Y zeroing depending on the machine state.

Output Triggers


These exclusively control LEDs on my control panel, alongside some of my macroloops.

Xbox Controller Settings


See my previous post to discuss these.
