Thanks for your answers, they have put me def in the right direction. What i have tried since: (i have one pin for all limit and home switches)
modified the .ini file to: [AXIS_0] TYPE = LINEAR HOME = 10.0 MAX_VELOCITY = 10.0 MAX_ACCELERATION = 50.0 STEPGEN_MAXACCEL = 62.5 SCALE = 533.333333333 FERROR = 1 MIN_FERROR = .25 MIN_LIMIT = 0.0 MAX_LIMIT = 300.0 HOME_OFFSET = 0.000000 HOME_SEARCH_VEL = -2.000000 HOME_LATCH_VEL = -0.937500 HOME_IGNORE_LIMITS = YES HOME_SEQUENCE = 0 HOME_IS_SHARED = 1 ... same for axis 1 and 2 and modified the .hal file to net all-homes-and-limits <= parport.0.pin-13-in setp stepgen.0.position-scale [AXIS_0]SCALE setp stepgen.0.steplen 1 setp stepgen.0.stepspace 0 setp stepgen.0.dirhold 35000 setp stepgen.0.dirsetup 35000 setp stepgen.0.maxaccel [AXIS_0]STEPGEN_MAXACCEL net xpos-cmd axis.0.motor-pos-cmd => stepgen.0.position-cmd net xpos-fb stepgen.0.position-fb => axis.0.motor-pos-fb net xstep <= stepgen.0.step net xdir <= stepgen.0.dir net xenable axis.0.amp-enable-out => stepgen.0.enable net all-homes-and-limits => axis.0.home-sw-in net all-homes-and-limits => axis.0.neg-lim-sw-in net all-homes-and-limits => axis.0.pos-lim-sw-in ...same for axis 1 and 2 but when i try homing i get an joint 1 on limit switch error.... it seems to me that the "Ignore limits =yes" in the ini file only ignores the limit switch signal for the respective axis but still tracks the other axis, although they are not active.... Did i make any obvious mistake, or is there a way to ignore also the other limit switches during homing? Thanks Nik P.S.: I have attached the ini and the hal file if there should be a bug elsewhere... > Date: Fri, 9 Apr 2010 17:51:29 +0200 > From: esla...@gmail.com > To: emc-users@lists.sourceforge.net > Subject: Re: [Emc-users] pin configuration for diy xyz stepper controller > > Andy Pugh pravi: > > ie, assuming that Pin 11 is the "all limits and all homes" pin then > > set it to be the combined pin for the X axis and then edit the hal > > file to combine all the axes on one pin. > > Something like: > > net all-homes-and-limits parport.0.pin-11-in-not => axis.0.home-sw-in > > axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in axis.1.home-sw-in > > axis.1.neg-lim-sw-in axis.1.pos-lim-sw-in axis.2.home-sw-in > > axis.2.neg-lim-sw-in axis.2.pos-lim-sw-in > > (All on one line, ignore any spurious line wrapping). > > > > You will need so assign a home sequence number to each axis so they > > can home one at a time or EMC won't know which one has hit a limit. > > Note also that this might not actually work, I have not tried it.
