At his point I am beyond frustrated. I have run all diagnostics as recommended by Shapeoko with the limit switches and everything passes. However, when I initialize the machine, it goes back and activates the y switch and then it just stops without completing the homing cycle. I have tried everything but nothing helps.
I had problems previously as well and I did random things such as taking out all cable connections and rejoining them etc. Sometimes it works sometimes it doesn’t. Has anyone else experienced this. I was in the middle of a cut on an expensive wood when it just malfunctioned and destroyed the entire 3 hour worth of roughning cut. Now the machine won’t even work.
homing switches — are they securely in place and all connectors secure and each can signal reliably based on machine structure or a metal post triggering it
motor wiring in good condition and all connectors secure
pulleys securely in place with both set screws tight — put a witness mark across the end of the pulley/motor shaft to monitor this
belts properly tensioned and belt anchors secure
linear rails and blocks properly lubricated and kept clean
Completed all above steps now including resetting the belts, lubrication and wiring check. Still the same issue that the machine gets stuck upon hitting the y limit switch. No noise whatsover, just dead after this. I have shared videos via email to support.
After redoing and cleaning everything up and tugging on the wiring to the x axis motor, this seems to be working now. I am running a test cut again and fingers crossed if it goes through then one more time this lives to see the day.
Bad connectors are notorious for causing random issues - my SPROXXL had both the X-axis & eventually the Z-axis motor connectors give me problems.
You can easily check if a wiring connector is an issue by jogging the axis & then wiggling/straining the connector in question. If the motor stops/stutters/makes a grinding-type noise, the connector is not providing a solid connection.
The motor connectors really do need to be secured well & shielded from anything which might strain them during operation - like a vac hose. Some people zip-tie the 2 sides of the connectors together to help maintain proper connection.
If a connection is really bad, then replacing the wiring harness may be in order - if you can get that warrantied. Otherwise just replacing that connector if you are so inclined. Some guys have just cut the connectors out & hardwired the motors for max reliability. Obviously, in doing this, C3D would no longer warranty the wiring harness.
