Hi Adamson, I’m very sorry I didn’t see your message until now. Sorry for the delay in responding.
From the photo, I can see that the Art2BodyA part is positioned further out than it should be (looking at the photo, the Art2BodyA part should be about 2-3mm further to the right).
If you don’t mind, please check the following points:
– Check that the gears on the joint 2 motors mesh perfectly with the gear crown on the Art2BodyA part.
– Check that those same gears are correctly inserted into the motor shaft and that they are not pushing the Art2BodyA part outward.
– Check the length of the smooth rod that acts as the shaft on that side of the joint. If it is longer than it should be, it will push the Art2BodyA part outward.
Best regards, and apologies again for the delay in replying.
