Crash Detected
On two of my printers, I am getting a crash detected repeatedly. No crash appears to have happened? Both printers are over a year old. Do I need to replace the bearings?

Every once in a blue moon I'll get that 'crash detected, resume print?' message and I'll inspect things and it did not appear that the nozzle could have touched anything. In every case I just re-preheated and restarted and the print completed fine.

This happens to me occasionally, but mostly when the printspeed is too high. I think that the crash detection is set too sensitive. Reducing the print speed (may cause lost steps or layershifting) has usually solved the problem. But it is also possible that worn linear bearings cause the crash. I don't have any problems with this, because I changed to brass bearings a long time ago.

I had a print yesterday. I litterally got 1 for each level. That makes me think it is due to the Z axis.

crash detection can of course be triggered on all axes, i think also including the e-axis, if the extrusion rate is too high, for example. Maybe your trapezoidal nuts of the Z-spindle are already slightly damaged? After 1 to 2 years of operation, this is not unlikely.

Check if nozzle hits the model/infill.
Loose bolts/screws is also possible, check the whole printer if something is loose.
Hold the extruder, and see if it moves to much, or bolts is to loose.(I had this).
Check if all axis move by hand without power on the printer, if it hits something.
Check also at the backside of the x axis, if cables hit something.
Check belts if they are not to loose.

In addition to mechanical issues, acceleration is a very important setting to reduce "false positive crash detection". The speed is not quite as relevant as the acceleration. In the user-defined Start-G-code from PS, add for example:
M204 S500 T500; sets acceleration (S = print, T = retraction) to 500mm / s²
or the same just new:
M204 P500 R500; sets acceleration (P = print, R = retraction) to 500mm / s²
Without an M204, the maximum values of the firmware (1000mm / s²) are used.
It would be nice to hear whether it works for you.
thank you!

The setting of the M204 can be saved permanently with an M500. Using a terminal (OctoPrint, Pronterface) you can check the current setting of the M204 with an M503 cmd.
