Hello everyone
First time posting here, hope i am in the right spot for my post
My buddy Mike has a laser machine he bought from China
The Label on it is as follows
SIHAO
Shanghai Sihao Machinery Equipment Co, LTD
Not sure if that's the brand or if its not, what the brand is.
If a model number is needed I'm sure i can find it somewhere on the machine.
Its a 4'x3' Table 150watt Laser
I have been using it all week and its been fine.
Today I was doing an engraving that was 42" long and 5" tall on a piece of rough cut live edge piece of wood.
Everything was engraving fine so I went off and did some other duties at work.
I came back about 5 min later and still was fine, again left and did some other stuff.
Again I came back but this time it was moving side to side and the laser was working but it was not moving on the Z axis. it was engraving over the same spot over and over.
So I hit the cancel button on the machine to shut it off fearing that a gear or something could ge
I went to use the arrow keys on the machine(not the computer) and it started acting funny. If i pushed up it would go up for a second then back down. So I pushed down and it worked fine. So I pushed back up and it went down again.
It is also making a terrible noise while it moves now. Where as before it was smooth and barely any sounds.
So my buddy was in the laser room tinkering trying to figure out what's going on and here are somethings that he has found
1) Least important but need to know. The image is upside down and reversed I'm sure that's just a setting in the computer so not to big a deal
2) The laser head moves fine back and forth while engraving but nothing else........UNLESS you put slight pressure on the bar the head is attached to that it rides on then it moves but you have to keep pressure on it. if you let go it stops, well it doesn't "stop" it jiggles like its trying to move but it just wont. (this machine has been used very little so I don't think its a worn belt, but I could be wrong).
Please let me know of any other information you may need to help me with my issue and I will post it
Thanks so much for your time
