Thanks Chris, just wondering how the scaling is done for me? After turning the pot from end to end once I have a perfectly working knob calibrated 0--200% feed override. Something inside halui is adjusting to my pot travel. Might be that what should be an endless encoder input hits max and min override and so my limited count range is "fenced in".
BTW, after just a few months of use I have found that EMC2 often knows what I want to do and adjusts accordingly. -----Original Message----- From: Chris Radek [mailto:[email protected]] Sent: den 3 mars 2009 20:01 To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] halui.feed-override On Tue, Mar 03, 2009 at 07:36:14PM +0100, Lars Andersson wrote: > Hi list, > > I have > halui.feed-override.scale to 0.00047 > Feed override range set to 0-200% > A pot connected through input that feeds ==> halui.feed-override.counts > which is changing from 14 to 4086 with the pot > > Feed override is at 100% when AXIS starts up whatever the value of > halui.feed-override.counts from the pot.

An encoder. That's a differential input -- counts go up, FO goes up .00047 per count. counts go down, FO goes down .00047 per count. It's meant to be used with an encoder that you can turn forever. ---------------------------------------------------------------------------- -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
