Can I ask if backlash is now handled correctly in Version3.1?
Coordinate display matches actual position?
I also assume that the DIR change timing issue is now resolved.
Thanks for the excellent and quick response to past problems.
Richard

The DIR change timing issue has been resolved.

Ver: 2019-05-21-110 Description:
1. Add the Ext-key function definition(#446,#447) configuration item: Disable(4), to turn off the Ext-key response;
2. Improve function backlash, all motion mode have increased the backlash;
3. Improve the coordinate display when the backlash is enabled, to ensure that the coordinate display match the actual position;
Note: To ensure that the backlash is always performed correctly, the following configuration is strongly recommended:
#113=1 "Arc interpolation algorithm selection"="Soft algorithm"
#448=0 "MPG control mode"="Open"
#114=0 "Jog support in continuous mode"="Mode 1"

slib.nc in the firmware supports fixing drilling cycles on axis A (G73, G81, G82, G83).

That is really great news re backlash, however is that just V3.1 or V2.1 as well? I do not have a controller handy to physically check the install.
What is the function of #448 and its options?
Thanks for the update

This new feature is supported on all DDCS.

When #448=0,Open the MPG control Mode,means the MPG will work in precise mode.In precise mode,the MPG will send out each pulse which the handwhleel has gernerated;
When #448=1,close the precise mode,when the user stop turnning the handwheel of the MPG,the MPG just stop sending pulses.
