Following the previous problem, I changed the cable, the perforated tray, the hot-end, the nozzle, the pcb and the thermistor / resistor.
After that, I started jobs, and I had a good results
Yesterday evening, I wanted to launch another job, bigger surface / volume and I had warping on the front side of the board.
Have you set fan speed in Z-SUITE to 0%? This is recommended when printing bigger models.
Is HEPA Cover fan speed set to minimum?
You can also take a look at our Complete Guide on How to Avoid Warping. Z-ABS Juice mentioned in the last paragraph is simple to prepare and it can really reduce warping.
No need to worry about the Z-ABS juice. Just don’t apply it near the small connector, it doesn’t affect the calibration process.
As for the calibration, can you recalibrate the platform and take a picture of the values that you get?
