I just purchased the Shapeko 5 pro with the spindle.
I successfully ran 2 simple jobs, then this came out of nowhere.
When lowering the Z axis, about 3/4 down, it makes a sound like it’s binding and pauses, then continues. It was previously working fine. Doesn’t occur when raising, only lowering.
When I manually turn the threads to lower the gantry, I am able to lower to the bottom and I feel no binding. (I am unable to push the gantry down but can lift it up.)
When I lower the Z to desired location and “Set Zero”, it goes over to the bit setter, etc. and appears to be ready. When I fast move to Z location, it makes that binding sound and stops short (Didn’t do this previously). (Zero location doesn’t match what I set it to)
Previously, my job was running fine doing V carve, then out of nowhere, it started cutting deep into the wood ruining the job. That’s when all this started.
Unable to produce consistent results in order to determine the issue,
I tried a simple rectangular pocket on a piece of scrap wood. I set the depth to .04"deep. When I hit start, it bored all the way through the wood (approx. .50" thick) and began to run a .5" deep line.
My relatively new 5 Pro with spindle just started to do something similar.
Mine was cutting great and then just plunged through the material and about .5" into the spoiler board and broke the bit. I stopped the cut, shut down the machine, powered back up and tried to initialize. The Z axis made a horrible noise and would not go to the home position. After failing to initialize I would get a GRBL Alarm 9 code (limit switch). I replaced the limit switch with the spare that came with my 5 Pro but got the same results. I reached out to Carbide Tech Support and got a response back within the hour. Fleming with Carbide 3D is awesome!! Fleming had me jiggle the wires and connections going to the Z axis while the machine was powered on. When I moved the Z axis stepper motor wires you could hear a thumping sound coming from the stepper motor. I disconnected the stepper motor and then reconnected it and was able to get the Z axis to work and allow the machine to initialize. This fix did not last long and the Z axis stepper motor connection became extremely hot to the touch. Carbide 3D is sending me a new stepper motor and hopefully that takes care of it.
I should have the new stepper motor this Tuesday and will keep you posted on the results.
I believe I may have found the issue. It appears the bushing behind the gantry is out of line with the threads slightly. When I get the gantry off, I’ll upload a Pic
It appears the nut that connects to the bottom of the motor housing came loose and fell. That’s it with the blue. Going to tighten it back on and retry.
