I have asked this question in the posts before.
When I set backlash settings these are visible with the actual move on the display.
For example, I move the X cordinate 10mm backlash setting is 0.32 mm.
The table moves to the correct position but dispalys 10.32 mm.
Please can you help, this cannot be correct.

I would also like to understand motre about backlash compensation.

I think a recent update made some changes to the backlash algorith.

A couple of questions:

1. Do backlash compensation work when jogging with the controller?

2. Does backlash comp. work when using MPG wheel?

3. I also notice the display shows the compensated move.

Can someone please explain what is happening.

My friend in  the UK also requested info on this backlash problem.
After many weeks of no response he sent the controller back for a money refund.

At present, the controller only performs backlash compensation when executing G Code. Manual mode (CONT/STEP/MPG) has no backlash compensation, so it is necessary to manually eliminate the backlash before starting machining.
In addition, the coordinate display does not eliminate the compensation amount, for example, the backlash compensation value is 0.1, the initial position of the X axis is 0, and execution:
G01X5
G01X0
The X-axis motion trajectory is:
0->5 (forward motion 5)->4.9 (reverse compensation 0.1)->-0.1 (reverse motion 5)

Én nem használom a backlash -t.
G0 x0
G1 x50
G0 x-1
G0 x0

Másik példa
G91
X50
X-51
X1

Így mindig pontosan nullára áll . Teljesen mindegy hogy mekkora a szán játéka.
