I just finished building my printer and it was fun.
I only encountered three problems during the build:
On the Y axis the cable for the heater bed turned out to be a little too short. THis could be my fault. I probably did not check the cable length properly. Not a big problem though. I removed one of the cable ties and now the bed can move all the way forward and backward.
Second problem was the end switch of the Z axis. Somehow it was activated by the bottom edge of the Z train’s left alu plate and not by the adjustment screw. So I could not properly adjust the Z axis. I think this would be no problem if the alu plates would be mounted the other way around ( with the smaller 10 mm side down and the 15 mm side up ) But I double checked the manual and it says I mounted the plates correct. Then I tried to place the switch a little further to the left but this was not possible due to the length of the screw holding the switch. If I placed a spacer between the switch and the motor bracket I could not fit the nut on the switch screw. Finally I realized that the fan screw was a little longer than needed so I decided to exchange the fan screw and the switch screw. This allowed me to place the switch exactly below the adjustment screw. See the pictures.
Last problem is that the X axis movement is a little ‘bumpy’. Could this be due to the center hole of the toothed pulley not being properly centered? I don’t know if you can see it in the pictures I took but the pulley in fact more resembles the shape of an egg. This is the only flawed piece I found in the whole kit but I think it’s a rather critical part of the printer.
All in all a great assembly kit. I am looking forward to do more prints as soon as I get more PLA filament and my X axis problem is resolved somehow.
