We have again run in to a problem like stated before on the forum. That is that during the passthrough print the laser arm derails itself during the line up proces.
This is now the third time this has happend. There is nothing elevated there is no debris on the sides I did not bump into anything and everything is clean belts are tight etc.
What I did notice is that the arm moves really fast to where to take the picture for the line up. And that is when it miss align its self. Than it moves back really quick and bumps and aligns itself again because of the speed I guess.
After that happend I re tried the allignment and than it did not derail but pusses the alignment about 1 inch lower than where it should be. This happend printing a giraffe I could not finish.
Why does the laser sometimes move so fast and other times really slower ?
Maybe my English is not 100 ok that is because I am dutch so you know.
This is my third machine and when it working ok I really like the machine but this has taken so much of my time and money and material that I seriously like stated before and before apricate to be compensated for al my trouble and this time for real !
And have the decency the respond to the request because gf always ignore this.
In the attachment is a film where you see that the same thing happend like stated above.
But here i thought maybe the inch lower alignment was only on the screen an maybe it was aligned in the machine. But as you can see it wants to go the inch lower like on the screen.
My guess the stepper motor is not ok. I have been making lots more passthrough prints whit previous gf and never had this problem this machine is not ok.
Also when moving the laser arm when its turn of it isn’t a smooth ride.
I would appreciate a solution as soon as possible.
this was send by email and have had no response!
Thank you for your effort !!
