Give LVD a call they should be able to troubleshoot it... I was up at their facility last week in Buffalo... Most parts are being made in the usa now...
Does anyone out there have any ideas as to what might be causing the pressbrake to "shudder" on the downstroke - no problem during the freefall part but once it passes the mute point it seems like the pressure isn't being maintained. Also the machine won't calibrate the tool in "Production Mode". Any suggestions gratefully received!

Thanks for the suggestion .... unfortunately we aren't based in the USA.
I was at there facility today... They are more then helpful if you give them a call..
Did you change springs on the prefill valves?
If machine is old, it can be that springs are tired (or broken).
Better to change both springs on the prefill valves on the old machines. (10 years and more).
I am sure that your machine will work ok after that a long time.
