Hi can can anyone help me out my machine seems to be all over the place. Can anyone shed any light as to what’s going on? Sometimes it runs alright then the y axis wants to go in different directions cheers Lucas
Random direction changes points to wiring: docs:blackbox-4x:faq-identify-motor-coils [OpenBuilds Documentation]
Do the checks first to confirm it is the case, but if it is - couple possible reasons: - a terminal left slightly loose and wire pulled out recently - terminated with insulation pinched into terminal along with the wire causing bad contact - terminal loose enough to cause a bad connection, but not pulled out yet - cable management issue causing some tight radius bends, or stretch/strain/pinch point issues causing damage to the extension cables itself - etc The symptoms are consistent with what you'd see if only 3 of the 4 wires are making solid contact throughout
because the machine moves and vibrates and copper work hardens and cracks when bent repeatedly. that is why we use cable chains and cable chain rated cables inside them (preferably) and we make sure that no moving wire makes a sharp angle, smooth easy curves is what we want, with no stress points..
