Dear ETC and EOS Family Team,
Yesterday I was in a venue with Mac250 and MAc250+ units (not Entour or Krypton). I had some problems with gobo control.
On the Mac250+, I was able to rotate the gobos continuously, but only in clockwise direction. On the Mac250 (classic / non Plus), I was completely unable to rotate the gobos continuously.
I checked the fixture profile, and for both of them, it appears the profile doesn't match Martin's definition.

EOS definition of the Mac250 (non plus) for DMX byte 5: DMX-value 0-255, user value -100 to +100. no subsections.EOS definition of the Mac250+ for DMX byte 5: DMX-value 0-255. "Index" when Gobo wheel mode is Index, "Rot" when Gobo Wheel Mode is Rot, Rot Scan +, Spin + Rot, Spin - Rot Martin's information for byte five (both Plus and classic): 0-2 no rotation, 3-127 CW rotation, 128-252 CCW rotation.This (and other) information certainly doesn't align, and probably explains the problems I was seeing.
If I had regular access to such fixtures, I would attempt to adapt the fixture profile to make it work. However, I don't have access to any, so that probably isn't much of an option.
The Eos profile is using the virtual parameter called "gobo wheel mode" to define whether or not DMX ch 4 is in a "standard" gobo type or an "indexed" gobo type. The mode of DMX ch 4 will affect the mode of DMX ch 5, where 0-255/0-100 range is applicable to indexed gobos and the rotation ranges (i.e. 0-1 no rotation) is applicable to standard gobos.
While this may explain the differences in appearance between the Eos profile and the manual's DMX chart, I believe the function Gobo Spin + and Spin - function may be broken in Eos, as selecting these options on Gobo Select will cause all gobo selections to disappear. I will inquire with the Eos team on the functionality of DMX ch 4 and ch 5 of these profiles to verify how it should work in the software.
uhm, not commenting on this specific issue, but since spin means the whole gobo wheel is turning there is no specific gobo to choose...
ah ha! that makes more sense. still waiting to hear back from the Eos team on the rest of the profile.
