CRASHING THE REVO NOZZLE ON THE BED

Hello,

yesterday I decided to try the REVO 0.20 nozzle, so without thinking much 😖I removed the 0.40 REVO and screwed the new 0.20 nozzle and started the first layer calibration.

Unfortunately as soon the printer performed the homing, the nozzle crashed on the bed creating a punch hole on the bed near the 0,0 position, and before I could reset the printer, it went on the right top of the bed and performed another hole.... 😭 

This incident surprised me, since I would have expected that two REVO nozzle were the same height, may be a few hundredths of a mm of difference.

But when I checked the situation, the offset was much more, and I had to low the SUPERPINDA around 3 mm. 😧 

That sounds impossible to me so the possibilities are:

  • For any reason I moved the SUPERPINDA up during nozzle change.
  • The previous REVO nozzle was too deeply screwed.
  • The current REVO nozzle is not completely screwed despite it seems to be fully screwed.

 

Moreover after the first attempt to setup the PINDA, during the First Layer Calibration, I realized that the MK3.5 - 6.0.2 FW supports a maximum distance of -2.000 mm and I had over 2 mm. Not sure, but I think the original MK3S FW had -2.5 o -3.0 range. So I had to put the SUPERPINDA more near the bed.

However the SUPERPINDA screw is a pain, since once that the PLA take the form of the screw, moving the SUPERPINDA up or down of a small amount is almost impossible, because even if the threads are moved a little up or down, they tend to skip and move back into the old PLA hole shape they were. 😑 

Further controls will follow.

- Does anyone of you swap REVO nozzle without performing a dismount/setup of the SUPERPINDA ?

Regards

Every time I change the nozzle I do an pinda calibration. It is a few minut's job. You can damage the buildplate if the distance between the nozzle and pinda is incorrect.

I never recalibrate my superpinda between nozzle changes. With nozzle wear it's sometimes necessary to check the Z height, but that's as far as it goes.
