Oh I forgot to say I gave up on the gantry component once the JA branch could home a gantry correctly and now it is in master. JT On 9/5/2016 4:14 PM, Danny Miller wrote: > On 9/5/2016 9:24 AM, John Thornton wrote: >> Sounds like your home switches for the gantry are not connected >> correctly

Re: [Emc-users] Can't figure out homing on gantry

Sounds like your home switches for the gantry are not connected correctly in hal. You do have one switch for each joint right? JT On 9/5/2016 7:34 AM, Danny Miller wrote: > > On 9/2/2016 9:45 AM, Charles Steinkuehler wrote: >> On 9/1/2016 9:28 PM, dan...@austin.rr.com wrote: >>> Well, wait-

Re: [Emc-users] Can't figure out homing on gantry

I floundered around with other components while trying to set this up, and was told "WTH are you doing just use 'gantry'". So I went with gantry component, and it's worked ok. But if I need something else, I'm open to it. I have the RT version of LinuxCNC. Will that update with this JA stuff

Re: [Emc-users] Can't figure out homing on gantry

OK, well the gantry man page says: "All controlled joints track the commanded position (with a per-joint offset) unless in the process of homing. Homing is when the commanded position is moving towards the homing switches (as determined by the sign of search-vel) and the joint home switches

Re: [Emc-users] Can't figure out homing on gantry

What's that mean? Does it just drive both in tandem until both switches are TRUE, then call it homed? That wouldn't work, I need independent homing for sure. Not sure what the Probotix code is saying but I'll try it out later: # join the home switch signals so that both switches have to be
