Ok. So, I am completely shot on my 3d printer. I’ve purchased and assembled a delta kit (HE3D Delta type) and am having about 0 success in getting it to work. I’ve decided to restart at step 2. (step one would be assembling the thing). I’ve uploaded new firmware to the arduino board, but need to figure out things like steps per mm, print bed size, etc. to configure this properly. Without completely destroying the assemblage, is there a way to figure this out? or do i need to deconstruct and go from there?
