I have started putting a new tube in my K40, how far should the laser be from the 1st mirror? I’m guessing as my new tube is larger 66w!
Isn’t that tube too long?
I added an extension to add for the longer tube from light object plenty of room!
I can’t think of a reason it really matters. The closer the better to decrease angular sensitivity but not so close as to make adjustments and targets a challenge.
tube from light objects also?
The distance doesn’t matter, but in the future take pictures before you remove old one.
Also are the mounts big enough? The diameter of a 60 watt tube is generally larger. My true 40 Watt replacement required changing the mounts out.
No purchased from another firm , twenty dollars difference between 40 w and the 66w!
Had to replace tube, broke due to cold
@Jerry_Martin What length is your tube?
@Matt_Staum 40 inches
