realize this has not been active for a while now, i feel there is not always enough information shared as answers are found to issues in mach. i have NO doubt some one will be seaching for this same issue someday. i will pass along what i have learned fixed my issue, so that 6 months or a year it may help someone else.
W7 x64, use compatabilty mode, xpsp3 run as admin.
this may or may not be the cure for everyone but, for me & w7 x64 and dmc4080 asus mother board, and my limit/home switches being seen by mach on the diagnostics page yet not actually working to home the machine it did. my issue was mach saw my home on diagnostic screen, if i activate the switch it would error out stating switch is active mach can not home. deactivated mach would home but ignore the switch when it hit. this cant be both ways!. if it works cancels home why wont it work when it hits?
i chased this for hours on my galil. active low, active hi, cn1 cn -1.
realizing mach was seeing the home sw, the galil was and they both had the correct active setting in the beginning. yet i spent hrs thinking it was comm, wrong settings. hit the switch mach complains i can not home the axis as the limit switch was active, yet would never find it during home? yea ok.
shut down mach, change the compatability mode and off and running.
the reason i am posting to this are below. we all run into an issue and scrub the forums for answers and lets all agree, its alot of time searching, and depressing to see an unanswered question that can help us.
looking at the some simple questions many ask, that are many legit ones yet they go an answered for years. no doubt in my mind many people search the forum for an issue, find joy that they came across a post with an issue they have and let down to find no answers, many views
ones that bother me the most are the ones that are pages long, 4 or 5 people assist and the answer is never posted for the next one of us who may need it.
there are not many members who dont have to ask questions at one time or another and information shared helps us all
many members have migrated to W7 and W7 x64. M$ is pushing us all that way. most of these issues will disappear when mach4 is released. for me i wont be upgrading to mach4 for some time now.
so there are legitimate setup and programming issues for some with W7 more so W7 x64. we should all pass knowledge along as we find cures to issues. it may not be exactly the same fix for each but it sure helps. W7 can be touchy for mach depending on motherboards, processors. i run it on all my machines. each one has its own setup issues. for me i build each Pc using the same components to help eliminate.
