Having the same issue with lock and top shim. I lock on CDCl3, and it says completed, but when I try to shim I get an error message that says “please lock prior to shimming.
Same issue regarding lock and topshim happend again as on Sept 20th. Topshim has kept failing with prior lock command. Using CDCl3 so shouldn’t be the solvent issue.
incorrect password prompt keeps popping up on AV300
cannot log in in av 300, but totally fine in av 500!
Same issue as Matt and Yifei. Possibly a temp problem since I ran in DMSO but temp was 23 C.
Same issue with Matt about LOCK and TOPSHIM
After locking in CDCl3, I see “lock completed”. However on applying topshim, I get the error “lock pending – please lock in before shimming”. Tried exiting and re-entering the program 3 times; tried waiting 10-15 seconds between end of lock and start of shim; “locked” and attempted topshim probably 15 times before giving up and cancelling the rest of my reservation.
Stuck on black desk stop screen. Unable to start program.
Bruker not opening/not logging out. Stuck on the desktop screen.
Spin rate error happened again after clearing with BSMS panel. Also, wasn’t able to lock DMSO for sample. AV300
