Coordinates maching axis movement gut G-code position is bad
« on: December 02, 2018, 11:03:36 AM »
Hi all

I got a strange problem on a newly configured machine.

When i move my axis 100mm the DRO shows 100.000 so that works.
When i zero my DRO and then enter G1 X10 the axis moves 20mm the DRO allso shows 20.00

Scaling is 1,000

Can anyone tell me where to look to solve this?

How are you moving the 100mm that is correct?

Hi,

I have startend over with a new configuration and configured all over.
Unfortunaly this did not solve the problem.

Moving the axis 100mm by jogging pressing the keyboard shows on the DRO 100mm
Entering G0 X10 the axis moved to 12mm the DRO shows 10mm
Entering G1 X10 the axis moved to 20mm the DRO shows 20mm
I have no idea what to do next.

Help please im desperate.

Sounds like you are in Incremental (G91) mode. Change to Absolute mode (G90).

Wow i used a newer laptop to drive the machine with the same configuration file.
Guess what....
All Works as expected now!
Can't believe the problem was the computer.

Thanks for the feedback!
