Hello all,

Anybody please help why UV coordinate very difference between Mitsubishi Wire cut EDM and Standard NX post for Mitsubishi as below:

 

Manufacturing cone shape: D1=10mm, D2=5mm

Mitsubishi Gcode output:

G41G01X5.Y0.U5.V0.H1
G01X4.998Y0.14U-0.002V0.14
G01X4.992Y0.28U-0.006V0.141
G01X4.982Y0.42U-0.009V0.14
G01X4.969Y0.56U-0.015V0.139
G01X4.951Y0.699U-0.017V0.139
G01X4.929Y0.838U-0.021V0.138
G01X4.904Y0.975U-0.026V0.139
G01X4.875Y1.113U-0.03V0.136
G01X4.842Y1.249U-0.033V0.137
G01X4.805Y1.384U-0.037V0.135

 This is code output from NX

G41G01X5.Y0.0U-2.5V0.0F0.0
Y.057V-.028
X4.999Y.114U-2.499V-.057

X4.959Y.637U-2.479V-.318
X4.951Y.696U-2.475V-.348

I imported this code to Mitsubishi Wire cut machine, the shape is not correct.

Looks liek NX is outputting UV in absolute values, Mitsubishi is expecting it to be incremental values (i.e. delta from XY position)

I've not touched Wire EDM posts in a while, there (hopefully) is an option to switch them, otherwise you'll have to figure out the math & change value to $upper(n) - $mom_pos(n)

(not sure the variable for "upper", but it should be the variable currently in the U/V words)
