Finished Upgrade to 2.5 - Bed crash with Wizard
Hello,
i just finished my MK2 -> MK2S -> MK2.5-Upgrade (04:25 am local time :-D) and the first problem -.-
I resettet the printer and erased all data, to start "clean". I updated the drivers and firmware before the reset, and just wanted to setup the printer by the wizard.
The wizard checks the Bed, Fans, X and Y axis with no problems. But if it comes to the test of the Z-Axis, the Extruder shortly runs down to the bed and crash's into it.
I'm not sure, why this happens: I alligned the distance between the nozzle and the bed (Extruder to the left + to the right, distance about a thickness of a sheet of paper) and setup the height of the PINDA Probe like it is described in the Manual (with a Zip Tie). I don't have the metal sheet applied to the bed, because i read in the manual, that the wizard would give me a info, when it's time to do that.
Has someone a idea, why this is happening / what i can do to fix it?
Thanks in advance... and,.. good night! 🙂

Hi there - i found the problem. I lowered the PINDA-Probe a little bit more, now it triggers the Endstop minimal above the headbet.
I also checked the function of the probe by holding a skrewdriver under the probe - i don't know that the new version of the PINDA has a little LED that indicates it's status 🙂

facing the exact problem with my printer.
No steel sheet on, and PINDA setup with the cable tie like in the manual.
After checking X and Y, the extruder presses the headbed down very hard. (like moving 2mm further than it should)
Because of lowering the PINDA for calibration process, when I do the first layer calibration I have to set the distance to -1.5mm!!!
And that is still with the steel sheet now on compared to the initial calibration process
With my old heatbed I was around -0.6mm.
Is there a problem within the calibration process?
Re: Finished Upgrade to 2.5 - Bed crash with Wizard
I'm now at -1,140mm Live-Z and it seems to be OK. The prints are quiet good, and i don't have to change the LiveZ anymore when i change the filament (testet pla, abs and petg - alle three runs a perfect first layer with -1,140) - thanks for the new PINDA2!
I think about it - if i should lower the PINDA to geht smaller LiveZ-values; but i think i don't do that: On very fragile, small prints, i always have a little bit Filament that's higher than the layer. If i lower the PINDA, it could be that it runs against the print - so i let it, like it is for "security".
Re: Finished Upgrade to 2.5 - Bed crash with Wizard
After upgrading I too found that running the calibration wizard always caused the head to crash into the heatbed. I think it is because for some reason with the 2.5s upgrade the PINDA doesn’t line up with the sensing circle on the heatbed (without the steel sheet) - maybe the PINDA is more to the right with the Mk4 extruder? - The PINDA was certainly to the right of the little dotted circle when it was running the test.
If I put the steel sheet on first, the problem didn’t occur because obviously the PINDA will sense it’s proximity to the sheet anywhere on the bed.
