Frage UCCNC step increment

Dear COmmunity,

I have an issue and I was wondering if one of you had ever encountered such problem before.

Everytime I click on axis movement (X, Y or Z), in the "Run" menu , and I tick the button for displacement by "Step", instead of moving with increments of 1 mm, 0,1; 0,01 or 0,001, it moves by 0,9975; 0,0975 and 0,0075 respectively. It doesn't move at all for 0,001.

Have you ever come across the same problem on your machine?

Thanks in advance for your reply,

Jules Garnier
