trouble with nozzle alignment

trouble with nozzle alignment

trouble with nozzle alignment

how importent is it that the beam is in a straight line from last mirror to lens? its like this, if i shoot a alignment shoot with nozzel at sheetmetal level the beam is in center but if i move the head up about 60 mm the beam is off with 0,3 mm( a little more then the beam). The guy that is teaching me the machine say that its not important that its off up there as long as its centerd at sheetmetal level, but i would want it to be better centerd all the way.what do you guys think, am i to picky?

do you align your mirrors your self or is this only for service guys? got only two mirrors, my machine pulls the sheetmetal around and the beam is on same place all the time.

RE: trouble with nozzle alignment

It's important that the beam is perpendicular to the plate.  Otherwise, you could have cutting issues (like tapered edge, or cut issues in 1 or 2 directions).
If the beam alignment is good with the head up and down, then I would think that your nozzle alignment issue might be related to a mechanical problem with the head up/down movement.
If you don't have cutting issues, and you don't mind having to align the nozzle at the plate height, and you don't have to cut "non-flat" materials, then I guess you could leave it like that.  In normal condition though, you should be able to align the nozzle at any height and not worry about head position.
If you are using a small nozzle (0.8mm for example), and the nozzle alignment moves by 0.3mm, it could be too much and cause cutting issues.  If you're cutting with bigger nozzles (2mm for example), 0.3mm movement will probably not affect anything.

For the mirror alignment, with some training, you should be able to do it yourself.  It's really not that hard.  Sometimes it just requires some patience.

RE: trouble with nozzle alignment

Thanks, well i think i will try to get someone to show how its done then. Got issues with cutting if i got long pices and the tension in the sheetmetal pulls it up.

RE: trouble with nozzle alignment

If the head has been whacking the material that's bowing up, then the Z-axis may be bent/damaged. you may not be able to align it if this is the case. This may be one of the mechanical issues footstrap mentioned. If this is the case then aligning the nozzle at material height may be the only way to get it to cut at all.
