Hello,
My Z Axis is defined as 60mm-up 0mm-down
If i start for example (code below) at 40mm in machine coord (G53), equal to 0mm in G54, the soft popup an error over limit 80mm !?
I think sofware add 40mm to the actual 40mm in machine coord. and say overlimit ... no no no i just want to go on 40mm in machine coord, in this example, no move from Z.

(1001)
(T2 D=3. CR=0. - ZMIN=-4.2 - flat end mill)
G90
G0 G53 Z40.
(Circular1)
T2 M6 (flat end mill D=3. 4 dents 3mm)
S10000 M3
G64
G54
M8
G43 H2
G0 X13.655 Y86.2
Z15.
Z0.
G1 Z-1.7 F200
X13.663 Z-1.767
X13.685 Z-1.83
... to be continued



If i stroke the same command on MDI that's ok. and after lauch my Gcode (without "G0 G53 Z40." it work fein.

Have you an issue to correct the control of limits ? button overidelimits dont work in this case.

Regard, Thierry

Nobody's can help me ?

What is the tool length of tool #2?

I don't use the tools length in Uccnc, all tool have a 0 offset

I still have the problem and still no solution, I am the only one to have this case ?

I'v see some other problem with soft limit, this is another one, but i think no one can help me.

I close the post

Your Z Axis is defined as 60mm-up 0mm-down which is typically backward. Normally Z zero is at the upper home position then it travels down (DRO goes negative) as it moves down towards the work. I think your 60mm up & 0mm down are what's causing the soft limits error. Try reversing the setting and see if the problem goes away.

Hi,

Thanks for your post.
I'v set my cnc as that because i need a absolute 0 on my ground (martyrdom in english ?).
I have some hand writing Gcode and im lazy to correct them.
I will try but i dont like to work with negative values.
