Moving Head Basics

Question

Just got el-cheapo MH to learn more about the control of these things. I've done some AutoMark experiments so Pre-Positioning is in the bag. 
 Scenario; MH on 1st auditorium bar (in middle) approx. 30' from stage apron. We are want to pan it across the stages 34' width and tilt it from the stage floor to 15' foot above. 
 1/ Is Fixture Profile Edit where I would set the minimum and maximum values? I.E if, when it's not powered my MH points to its lower left and upon powering calls this position Pan 0 and Tilt 0 then we want it to work in say the pan range of 40 - 140 deg and the tilt 80 - 100 deg. And not go beyond those values. I'm getting a bit confused about pre-set, home and so on. 
 2/ Which brings up an interesting question. Just look at pan; let's say we have restricted it's range from (its) 40 to 140 deg. Now, if we select it and set to 0% will that = 40 deg and 100% the (max) 140 deg? This would obviously make for a very controlled pan.

the position the fixture goes to when powered and there is no information from the console, the channels go to the Home position. you can change the fixtures home position either by editing the fixture profile or by setting a home preset. 
 to limit the fixtures movement you would need to edit the fixture profile. you will need to go to the Range section and there change the column DMX Min and DMX Max. those are the values that get output. the UserMin UserMax columns define what values you see (e.g. a value in degrees). 
 if you have more than one MH you will probably need to copy the profile and separately edit because since the MHs will not hang in the same place their limits will also be different.
