Re: Machine crashing when homing despite stop switch

ok, i made a video to illustrate the issue: https://youtu.be/QjMIq9Lw7YA There are two passing and failing cases on the video. My theory is that after the machine crosses certain value on the X axis the stop switch doesnt work anymore, as you can see on the video, when the switch is presed further f...

Re: Components not released - release time?

when i press pump off on the basic setup section the vacuum is gone and the part is released. I interpret that like the pump and valve work in manual mode, but not when picking and placing. Any manual commands that i can try in tinyG terminal to confirm this?

Re: Machine crashing when homing despite stop switch

I start homing way far from the X=0, so there is enough time, that is not the issue. The switch is pressed and the machine when it gets to the end and the machine keeps going and hitting the rail so i have to turn it off, at this point the switch is pressed. I have the machine homing at a very slow ...

Re: Components not released - release time?

ok, the vacuum is still to strong, solder paste tension is not enough to "pull it" any guidance on the pick up and release times? what values should i use? any other ideas?

thanks

Re: Components not released - release time?

should the sw turn off the pump as well? so you make sure the device is released?

Components not released - release time?

Hi, i am testing my machine by picking and placing components using the "pickup this...place here" option. The components are picked up successfully, but then what i try to place them, they just remain there and there is still vacuum on the system. After a while it falls (~10 seconds). Ele...

Re: issue with rotation motor

i forgot to mention, i checked the coils and resistance and it's good, i can see resistance on each pair and no resistance across pairs. So the coils are not blown at least and there is no short between coils. I also swapped the motor temporarily to the Z channel and got the same exact behavior. So ...
