I started to have an issue, which I came up with a band aid. Here is what is happening. When I first begin to print, while the machine is doing its calibration, the rear motor section makes a weird sound, like someone is putting a lot of torque on the motor, it is not high pitched more-like there is a jam which it is fighting. So while it is doing the calibration, the last part when it would go to the center to do the calibration, the head only travels halfway to the center, like it got stuck, it then tries to do the final calibration in the middle.
I’m very much into maintenance, so every, thirty hours, I clean the rods, magnet joints, and re-lubricate. In order to proceed to get a print, I found that if I do the movement test twice, there is no noise, all works fine.
Now note, the noise/movement issue I described above, only occurs the first time I’m going to use the machine in a print run, if I do consecutive print runs, I do not have any issues with the prints . The only thing I can think of, is I have my office on the second level of my home downstairs (basement) , which is about 60 degrees F, I was thinking maybe this is too cold and something needs to get a little warm. I wont know until the spring, if this is what really is going on, if the temp affects it or not.
What do you think?
