Can't get good graphs on VC4 400
This is 24th graph I did today. After 3 hours I still can't get the belts to align. It doesn't make any sense. When I loose the upper belt it doesn't get closer to the lower belt. Either the second smaller peak dissapears or nothing changes. I tried realigning Y rails, the X gantry. Measured distances between various points to check for obvious frame issues.

Getting there finally! I unbolted everything I could and tried to alignt and bolted again. This is the latest:

Here is a new one after I tighened the lower belt and loosened upper belt. No difference from the previous one
I'm not the best person to give advice given my own problems with belts on VC4 400, but maybe try to lower the tension on both do that two peaks are closer to each other?
your lower peak seems to be in the right range on the Y axis of the graph, if you brought down the higher peak closer to 3-4 1e6, I think you'd get closer to a good graph
I tried that. I lowered both to the point that belt were flapping agains the frame they were so loose 😄 I don't get why it doesn't cooperate. The higher (orange) peak basically says that upper belt has more tention, right? So if I loosen it then orange peak show go down, right? Instead if I do that then the smaller peak on the left completely dissapears

Can I leave it like that? I don't want to touch it anymore :mildpanicintensifies:
