Alignment issues

Post by daveinhull »

Hi,

I've now got the printer mechanics virtually built but have noticed a few issues or possible problems.

The first is that the y-axis motor hits the bottom of the x-axis motor when at its highest position and the nozzle and plate are about 5mm apart (picture 1). I'm sure I've read something about this but can find it a thread anywhere now.

The other issue or maybe a problem is that when the x-axis is parked (closing the optosensor) the nozzle is about 2 mm of the plate. I'm guessing this is OK because I think this will only be needed to calibrate the x-axis but could someone confirm that it isn't a problem.

Many thanks in advance,
Dave

Hi Geertjan,

Thanks for the reply and the thread link. I think I'll go with the Dremel idea and cut of the excess y-axis spindle. I think I may also add another nut to the plate supports as well. I'm guessing everything can be sorted out during calibration.

Are you seriously going to dremel the spindle? why not put washers on the motor fixing screws to offset it a little lower (and relocate the belt drive a little upwards to compensate)

Hi Lioric,

Well yes actually - what's it there for anyway and with plenty of plastic covering and a good Dremel metal blade it'll come off no problem at all. I'd need to put 5 washers on each of the motor fixings to stop it hitting the y-axis motor and then the screws would be too short, that or lower the heated plate with more washers on to the y-axis bolts and then they would be too short......

Actually, I reckon as an alternative I could just file a little bit of the y-axis metal work in one corner, it probably only needs .5mm and there's plenty to spare....
