Mini-LEM Amersfoort - 30 january OR 6th of February

[michelrietveld]

happened to me once a few days before a show, first no idea what happened, saw a line instead of a graph, closer look at the galvo mount revealed that one of the mirrors fell off, the days before i noticed a wave-like pattern on my lines and was already thinking of what this could be. My mistake was that i set the scanning speed too high in combination with a too wide scan angle.
I repaired the mirror by glueing it back on, before that i covered the mirror with "first contact", this is a cleaning liquid that you can peel of later to prevent glue attaching it to the mirror surface. Two component glue seems to be the best and make sure it is glued back in the center position. You also have to retune the set afterwards and the tip i got for the next time is to replace the mirror by a spare one, heating up the old fragments with a soldering iron or so seems to loosen up the glue and making it easier to gently scrape off the old mirror parts. Again a retune would be advised.
I know ledfreak3d on this forum, he lives in Hoorn, is one of the people who are able to repair such things for a reasanoble fee.
I don't know about the people coming to the lem at hobbybob if someone can/wants/dares to repair it.

I want your galvos hand them over
I dont really need the galvo's repaired, the guys who help me at the lem can have them as a thanks^^. Dont know who that person will be
The broken galvo mirror just made me know that there is no way back then taking on the challenge to upgrade and i fear there might be stuff that cant be done for the price or something similar.
Im going to purchase galvos no matter what, before the 30th.

That won't be me XD
I still am a noob with the hardware part.
I know how serveral things work, but thats it.

I do like to see that tuning though.
I read the whole tuning guide before.

Hi all!

I am new to the forum, and new to lasers and laser-displays in genral and recently bought my first scanset!
(from laserwinkel, nice to see you here )

I would like to come to the LEM very much to talk to some of you guys, and gain some 'field experience'.

Thing is I'm not available 30th jan, only 6th feb...
