Sooo this has me baffled.
I’ve been printing for literally years with my two X1s. Literally never had issues with either of them other than the typical user error and the inevitable tensioner arm break.
Then all of a sudden, about three days ago, I started a print with 3d Printing Canada’s standard black PLA and had the WORST under extrusions ive ever dealt with. I moved the spool and file to the other printer to finish the job and it went fine. I checked the nozzle for jams, checked the thermistor and thought maybe it had kicked the bucket so I changed it. Started it up again and the first few layers were fine and I got pulled away to something else but I thought it was fixed. Came back to the same terrible layer adhesion and under extrusion. Then the other printer started doing the same thing!! I thought maybe I got a bad spool so I just spent an hour clearing the nozzles again on both because I don’t have replacement .4mm on me. Then I used my fluke multimeter to check the temp of the heat block. My meter was showing a full 40C below the machine setpoint. I had the printer set at 200C and the meter read 142C. I thought maybe the thermocouple for the meter was possibly at the top of its range and decided to just run a print and see.
Sent some filament through by hand and it went fine, extruded with the touch screen, seemed okay. Started a little cube print I have, and the first three or so layers were fine and then bam, under extrusion city. I bumped the heat up on the touchscreen by 40deg and low and behold, PERFECT. FRIGGIN. PRINT. for the rest of the job. I just printed two more on each printer and manually adjusted the temp up by 40deg before the print started and it’s been flawless.
What in the FAAAAK is goin on??
I use Ideamaker to slice and Fusion to model. I have no idea how it would be possible for files from the USB to mess with the calibration of the hotend but I’m at a loss.
ANY help would be appreciated. I don’t want to adjust all my profiles up by 40deg and then have the printer do the opposite and have it burn the snot outta filament all of a sudden
Thank in advance!!
