Hello,
I had to replace J-Head in my home-made Prusa i3 XL. I've bought
this one with an additional fan. The problem I'm facing right now is that rectangular chamber holding the 0,5mm nozzle is loosening when I head up the print head. Even if I tighten it up when the head is cold, when it reaches 220C it is loose what have negative effects on the leveling. During printout, the chamber may turn freely what causes the head to lower its position. Do you have some solution for this issue?
Best regards,
Chris.
