Error "Unable to calibrate base plate"


#1

Hi all, I am new to 3D printing and Flux is my very 3D printer. I am having an error on my first print. Please see my screen shot

Not quite sure what I am doing wrong. Any help is greatly appreciated.

There are 3 force sensing resistors in the “corners” of the build plate nearest the rails and belts… When you start a print, each tower will home against the endstops at the top of the machine, and then the head should come down and tap 7 or 8 times in each of those corners, and go around the triangle 4 or 5 times before it does the same thing in the center of the plate.

What happens when you start a print? Does it tap any of the corners?

I haven’t seen this error, but I would look to see if the base plate is facing the correct direction.

  1. First, make sure that you are printing on the unprinted side of the plate.
  2. There’s a small hole in one of the points of the plate. It should be on the right-most side of the flux if you’re facing the front. You’ll see it under “Setup Steps” in the manual - https://flux3dp.zendesk.com/hc/en-us/articles/215794098-Manual

What is that little hole actually for? I’ve been lining it up every time, but I honestly couldn’t tell you why.


#5

I have absolutely no clue. I’ve been wondering myself.


#6

@Jimustanguitar, the print head only tabs one corner once and goes back up. Then the error message comes up.
@Milkdog, yes. i am using the unprinted side of the plate and i started with the hole in the right corner then turned the plate to a different corner. Error persists.


#7

I think I figured out what that error means. The Flux seems to think that there is leftover filament on the nozzle. I would check to make sure the there is nothing sticking out of the nozzle.


#8

I checked. there is nothing on the nozzle or anywhere around it.


#9

Is there a physical obstruction visible that would keep the metal plate from contacting the rubber corner pad?

If not, I’d contact support. Perhaps they have a console that can run an M119 command or something like that to help troubleshoot the FSRs.


#10

the plate sits very sturdily on the rubber pads.


#11

Yeah, hopefully there’s a GCode console hidden in Flux Studio somewhere to help perform troubleshooting like this. Definitely put in a support ticket, and let us all know how it goes.


#12

will do. thank you all for your help.


#13

I had this, and it was the hole not being lined up for me.


#14

@james_lan, I rotated the plate 6 ways and even flipped printed side up. No luck. Thanks.

I have submitted a ticket already.

I also noticed during the calibration process, when the print head hits the base plate, there is a very slight jerk to the left. see the gif below. thanks


Calibration error all the time
#15

It’s probably physically making contact with the plate, and that’s just the direction that it deflects as a result.

I’ll take a video of mine after this next print finishes.


#16

Here’s the routine that my machine goes through.


#17

Here is my “real” video.

obviously there is something wrong.


#18

has the machine worked before? or is this the first time? try to change the head in a different direction (take all 6 connector off and turn one side) and see what happened. also try to observe when the hit and tilt action causes any loose connection on any of the rod.


#19

I have rotated the head and swapped two of the rods from one side to another. Still no luck. i will try again this evening.


#20

Looking closely at the GIF I do not see a "jerking to the left. I see the entire print head tilting. As if the nozzle is contacting the baseplate but the print head is still trying to come down. Because the vertical/nearly vertical suspension rods have the mechanical advantage, the printhead TILTS to that side.
