Good Day everyone,… I come to you out of pure frustration… I finally have my CNC set up (almost)… Finally got to the part to connect my MAC OS and test for movement… I was able to get my Z axis and X axis to move and only ONE of the Y axis to move. My left one moves fine but my right one just grinds and grinds… I had a VERY difficult time threading the lead screw into the backlash nut, but with a little lubrication and some heavy duty rubber gloves , I was able to finally twist it all the way thru, it is SUPER tight and not able to twist even a little bit with my bare hands, but it seems as if the motor isn’t able to grab it and turn it properly since it’s so tight.
SO…I disassembled that back right motor and took the lead screw out and struggled to get it back in again and reattached everything…reconnected it to my computer and tried to test the movement again… It did the same thing… So I read the troubleshooting section and saw that I should jog the machine all the way back on the Y axis until it grinds to get it to reset. After I did that, the right motor that wasn’t moving at all now creeps ever so slightly in its movement… but NOW the left side doesn’t move at all! …Looks like the Lead screw came out of the motor and coupler, so I took THAT apart to re tighten and NOW it seems as though the lead screw will not even fit back into the coupler at ALL, like the lead screw all of a sudden is too big for the coupler, so I’m not able to push it anywhere close to the motor shaft and it barely is able to grip it for the motor to turn it. I don’t understand what is going on. How did it fit and turn previously? As for the right side, I think the lead screw is way too tight inside the backlash nut for it even to turn at all.
I am SO FRUSTRATED!! I just want to get up and running!. Do I need new lead screws? DO I need to try a new back lash nut?? I really don’t want to take this entire machine apart to take the back lash nut off! PLEASE HELP!!!
