Re: CONFUSED... Where to home too... Help! where should my home switches be.
Just to add some confusion here, one should not confuse a home position with a ''parking'' position. Normally a home position is where the Machine Coordinate System (MCS) is set to 0,0,0. The parking position could be an offset from the home position.
On the Haas, the home position is a fixed location set by limit switches and servo encoder index. The Work Coordinate System (WCS, G54-59) is set as an offset from the MCS (G53) and is set to the work. The parking position is an offset from the WCS, I think (I don't run the Haas). To park the Haas we normally move the table to the center, and to the front of the machine, Z is sent to the top. I don't know if this is done with a G28 or just a G0 move.
On my knee mill, 0,0,0 (WCS=MCS) is always set to the work, there is no fixed home position. The parking position is set per the job by moving the table and Z to a convenient location and clicking on ''set park position'', I think this is equivalent to a G28 move, but I have never used a G28.
