halui feed and spindle overrides behave differentl

When using the ...direct-value=1 option and writing to ...count feed override can be set to 1.2 (120%) but spindle override is clamped at 1.0 (100%). Even stranger, the count apparently "winds up" to 120% and must be "unwound" before the override begins to decrease. This behavior is also observed using the the count_up / count_down pins (at least the 100% maximum, I didn't fully test for windup).

The AXIS GUI is able to write 120% spindle override, so I suspect the bug is in halui itself. I don't have the sources (yet) to investigate further.

This is not really a bug.

First the upper limits of feed and spindle override can be set for axis in the INI file.
second halui and AXIS do not directly communicate between each other.
You are using two methods of controlling the overrides, each one thinks it's the only controller.

so either set AXIS override limits higher or lower the override limits of HALUI so they match.

My values to FOVR and SOVR are clamped in ClassicLadder, so windup should not be a problem. I'm using panel encoders that have a momentary pushbutton switch built in that I use for an immediate 100% value. It all works well except for the behavior of SOVR -- I'll review the .ini (and stepconf settings that created it).

Thanks, Dave

can you post your HAL and INI file please.

Well, OK, you asked for them...
(I'll be happy to discuss the details of this project if you are still interested).
StepConf writes 'MAX_FEED_OVERRIDE = 1.2' to the .ini file but not 'MAX_SPINDLE_OVERRIDE = 1.2'. That change fixes my complaint.
I have been trying to keep the .hal and .ini files "pure" (created by the Wizard) and making my changes in "custom.hal", but I am now forced to edit ".ini". Oh, well. REAL men don't trust Wizards...
