fixing a twisted frame that doesn't budge - Vcore 3.1 300
https://www.youtube.com/watch?v=h7ZTq2dDTkM
Hi! first of all, I've watched this famous video about the topic: I'm trying to fix a slightly twisted frame on my printer, and considering what's in the video and my current mesh I tried doing the following:
1- tapping on A to push it down
2- trying to push B up
the point is, if I screw the four screws mentioned in the video (and the RR commissioning guide) for each side they don't budge a bit, I even tried lightly tapping on A with a rubber hammer but the results are almost none (even hitting the extrusion with a force I wouldn't be comfortable applying more than a couple times honestly lol)
Any help is appreciated, how have you handled this problem practically?

If you can't get the frame to move, you could try shimming one of your rails to get the same effect...
Similarly, sometimes just playing with the torque on the rail bolts can help...
That said, you are looking for less than 0.5mm of movement in the frame... You might just need to be a little more persuasive... If you don't want to strike the machine directly, consider using some means of leverage to aid in applying torque where you need it...
