The following has happened with gcode from both Fusion 360 and Aspire. While running gcode, the z zero is reset to a much lower setting without any user intervention. I’m talking a half an inch lower. I have cut deeply into my spoil board on a few occasions. Luckily I missed the t-track! I had assu…

are you sure the bit isn’t falling out of the collet?

yes. on the second failure tonight, the bit was still securely in place after I stopped the cut.

Can you post the gcode? I’m happy to look at the gcode and look for something out of place. -Tom

marvel 24in small v.gcode (1.9 MB) Here is the gcode used. It did simulate properly. I hope you find something I did wrong!! I just don’t understand how the zero can reset during a cut. I did see a z axis drift before when 3D printing. That was caused by a loose set screw on the z axis coupler. I …

Can electrical interference cause this? I have the power cable from the router running inside of the coil that holds the z axis stepper motor cable. That was to keep the router power cable up and off of the table.

I found the problem! The connector to the stepper motor is bad. At least one wire inside the connector is loose. If I move the z axis up and down and move the cable from the stepper motor, the z axis begins to skip and stutter. I have a video of this. How can I get this fixed?

contact support and they’ll send a new one.

I have emailed support. Thanks for the quick response, even on Christmas Eve!!! You folks are awesome. For reference for anyone interested, here is a picture of the loose crimped wires. This is the male side of the z axis connection. [IMG_5373]

Thank you for updating us - I am happy you were able to find the problem - as this will no doubt help others as well. Happy holiday, Tom

Dennis, I too had a wire issue. Mine was with one of the Y rails. It was not getting powered due to a broken wire so the cuts were very poor. Support diagnosed it quickly and sent out a new cable on a Sunday!. It’s unfortunate that the connectors are so fragile, but we have a great support team behi…
