xyz homing issue

Post by Chay » Wed 22 May , 2019 14:43 pm

Hi all,

I've just been given the task of getting a Denford Novamill up and running. The machine won't home any of the axis. I exposed the limit switch on the y axis and when the stepper motor started it's whining I pressed the switch and the axis moved. I have let the homing time out once and that gave me access to jog which works fine.
I'm using the VR software. We want to get this machine up and running to give our students a basic idea of CNC. Any help would be really appreciated.

Update...
After a lot of messing about the z and y axis have homed though not consistently. When I try and home on the x axis the bed goes in the wrong direction.
I’m using vr version 5

Does the X axis move towards the Home switch or away from it when you ask it to home?

Have a look at the machine parameters for the NovaMill below from an older machine. It should be similar. (Setup, Setup Machine Parameters, (Password is denny)).

[Home]
X=0
Y=0
Z=0
Feed=500
Negative X=FALSE
Negative Y=TRUE
Negative Z=TRUE
Negative 4=FALSE

[Feed]
Default=100
Maximum Rate X=1500
Maximum Rate Y=1500
Maximum Rate Z=1000
Maximum Rate 4=500
Minimum Rate=20
Steps per mill X=200
Steps per mill Y=200
Steps per mill Z=200
Steps per mill F=200
Motor Direction X=1
Motor Direction Y=1
Motor Direction Z=1
Max Contour Feed=1000
Max Contour Angle=30
Jog Rapid Feed=500
Shortest Contour=0
Shortest Time=0
