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? Is there presetting dimensions in a file somewhere or does it have some sort of limit sensors? Anyone have any suggestions? ![20241221_224111](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/8/8bd65aa1dacea3716ce94deb1188d092a99c170c.jpeg) ---

Flip the printer around so you are facing the back of the printer. Reach under the back of the bed & feel for a piece of foam. You can’t see it, it between the bed & the rail. ---

Hello, For all the idiots, the same. 🤷🤷 I asked Sovol to stick a sticky note on the bed to remind users to remove this block of foam. ---

Is there just the two foam blocks or is there a third I need to find? I am also getting the thud, but thought I got all the foam blocks out? ---

The only one we forget (so far) is the block behind the printer between the bed and the rails. You can find it when you flip your printer. Otherwise, you can’t see it. ---

**By the way, Sovol sent a message saying that they’re going to do a printer improvement to fix this issue.** **It will be for the next buyers.**
