My previous comment was incorrect. A good g29 does run for a while (like 3 or 4 up and downs), but eventually does end with the message “Calibration Complete” on the display.
While the arrow shows where to plug the EZR Struder in (If you zoom in), I managed to plug it into the wrong socket. Note that from left to right, are: X stepper, Y stepper, Z stepper, EMPTY, then the EZR Struder. If you plug in the one that’s supposed to be empty the extruder moves along with Z. The E0 label on the board is to the left of the correct socket.
From what i can tell, an successful G29 command runs over and over forever. This is why you need to reset things before doing anything else. If G29 stops, check the display. If it says something about an ‘OFFSET ERROR’, it probably means that the screws that hit the end stops are set to different heights. I couldn’t get them even by measuring. I found the best way to adjust them is to watch where the calibration ‘taps’ on the plate relative to the white circle. The 3 taps should be about the same distance out from the center. If it taps too far out, make the screw higher on the nearest carriage (which makes it home lower). If it taps too far in, make the screw slightly lower (which make it home higher). You’ll probably have to iterate on it a few times since adjusting one affects the others a little.
Eventually when you calibrate the machine, the routine is going to require that these screws are close to the same height. Do your best to make them even. You may still have to adjust them later.
I had the opposite problem. If I screwed them in too far, some wouldn’t line up with the hole.
I think the phrase in this section “The Bowden tube will fit nearly the entire length of the hot end “ is a cut and paste error since we aren’t dealing with the hot end. I believe the tube can only go as far as about 5mm before the motor shaft.
When you are seperating all the parts from the laser cut panels, throw all the little scraps in a ziplock bag and keep them until the end of the project. There are a few small parts you may not recognize as being needed right now. At the end when you need them, you can go to the bag.
Note that to get the red stripe on the left, the ribbon cables need a half twist. This troubled me since the instructions say “The connection is keyed on the LCD itself so the orientation will be correct. “ I guess that just means the red stripe is in the right place at the display end.
Okay, I should have looked ahead one step before commenting on the last step, but I still feel some of this info belongs in the previous step.
Wait, there is yet another dangling connector. This one has 2 positions and a blue wire. This goes to ps-on, at the right of the board?
