Invalid coordinates

Please Login to Comment

Hello everyone,

I set up my Predator a few days ago and I have noticed that for some of my prints, the predator can get stuck into an invalid position whereby one of the pulley mounts gets lower than the extruder. The entire carriage gets stuck into a weird position and one of the steppers just grinds loudly until I turn off the print or the 3D printer. Overall, I think there's a problem with the slicer.
My question is: what are the chances of damaging the unit in such circumstances and which parts are more prone to break? I'm not sure if the grinding noise is due to the stepper motor missing steps or because the belt jumps steps. If it's the case of the latter, then I might think of getting some spare belts just in case.
It's also quite strange that the firmware doesn't check if the gcode positions are valid coordinate points.

Thank you very much and I look forward to your thoughts on this.

Kind Regards

If you think it is the slicer's fault, try another slicer. Also check the grub-screws in the top-pulleys, they are often not tightened. But since it prints also normally (I guess) maybe it is something completely different. Send some pictures.

Hello. Yes, definitely the slicer's fault. However, my questions is regarding the likely damages such a delta printer can sustain in case of invalid coordinates - or in case one of the limit switches fails, for that matter.

Kind Regards

The rods and bed are the most vulnerable and can break or damage.
