I have been using the printer with no issues until the last week or so. I’m very maintenance geared, so I do the re-greasing of all joints and poles every 30 hours.
This is what is happening:
During calibration, after the three main corners are completed, and it has to move to the center to do a center calibration, the whole head jerks to the right approximately half way in the same directions all the time. (Looking at the front of the machine always to the right) It then will do the center calibration there, and fail.
I have reseated all poles, Reflashed the firmware, just in case… I can do the movement test no issues.
What I have found, this only occurs when first turning on the machine, and I try to print for at least 3 - 4 times it has this issue. Then the problem goes away and it prints fine and calibrated fine. Also if I do the calibration via the menu, it does the samething for 3 -4 times.
The machine has been in the same room, and location for over a year, and no issues.
The belts seem fine, and like I said, after the 3-4 times of trying to calibrate, it will then calibrate fine and print no issues.
The only thing I have not tried is going back to 9.0 software.
