Newb here. Assembled my new 06 Plus Ace, ran through the original 15-minute calibration. All well. Print sample connector. Looks good. I GENTLY move the printer to another table, its final resting place. I decide I want to go through the full calibration again, so I allow the system to reflash factory settings. All well, it appears to sense all four corners and correct bed height.. I allow the full 15-minute calibration. No problem. Now I go to print the same sample as before. The head moves to the center of the bed, touches the bed top, then raises, then moves to the very back of the bed. The printer head is just beyond the edge, then the head drops, continues to just below bed top, comes to a stop when the stepper motors bottom out, and continues to try to power to a lower position, but just grinds until I cancel the print and turn the system off. Thoughts? One additional “symptom”. The bed slams fairly abruptly when it bottoms out in the forward direction. ---

I’m not sure if the Plus had the same issue as the ACE, but check for a black piece of foam under the bed. > [@Y axis thud/ bottoming out on brand new sv06 ace](https://forum.sovol3d.com/t/y-axis-thud-bottoming-out-on-brand-new-sv06-ace/6322): > > Just got a new svo6 ace but I’m having trouble with the y axis. It seems to be travelling too far foreward and hitting the end of its travel. When it does this it makes a thud and a clicking sound. I have tried all the calibration settings and updated the firmware from v15 to v19 but still no luck. While doing a test print (benchy) it gets halfway through then skips alignment about 4mm then skips back a little bit further on. Im guessing it’s all related. How does it sense the end of its run? … Also, there was no reason to do a factory reset when you moved it to another table, all you had to do was run the calibrations again. ---

Thanks, Lion. The bed did originally come with two squares of foam under it, but I removed those right away. I looked again under, and the path looks open. I did look at the calibration menu and saw two (I believe) calibrations, but they looked abbreviated compared to the original 7-step calibration. From now on, I will only use the couple of calibrations if I move it again. Thanks! ---

Apparently, the bed had skipped a tooth on the belt. I forced 1-tooth jump, and is printing flawlessly now. Thanks! ---

Point of note: The zero point for all axies is lost on power cycle or “firmware reset” from Klipper. The endstops for X and Y are “sensorless”. If the bed or toolhead are blocked from reaching 0 when you home the zero point will be wrong. Yes if the belt skips the zero will shift but you can “home all” and fix the zero points.
