Does anyone have ideas on how to remove lock-tight on up facing camera lens?
I hooked the camera's up to openPNP and tried the part recognition pipeline. Seems to work very well but because the part is not focused the alignment is out by about 0.1mm on one side.

Is the part height set correctly? This should be being used to adjust the focus distance for different part sizes

Yep, check part height and camera height in the settings. When OpenPnP wants to image a part with the bottom camera it uses the camera's Z location (set in camera properties) and the part's height to calculate where it should place the nozzle. When you set the camera Z, it should be with no part on the nozzle and with the nozzle bottom in focus over the camera. Then when OpenPnP images it adds the part height to this value.
Today I tested out our own feeder and tape stripping system on the TVM802. The stripping works independently of the TVM, so it works fine with the stock s/w. I made a completely new feeder block that solves multiple issues of the original one. And don't even get me started on the TVM's stripping mechanism...
So far we only ran test jobs. Placed over 500 of 0603 caps and close to 100 of SOT23. I think there was one discarded components in total.
My feeder block packs tapes tighter (3 mm spacing instead of 5 of the original), so more lanes can fit into the same space. It has 18 of 8mm lanes and some space for configurable lanes, which allows setting up an arbitrary combination of tapes of any width. (That part is not tested yet.) If you fill configurable space with 8mm tapes only it gives 11 more of 8mm tapes. So L side can host 29 of 8mm tapes in total.
My stripping mechanism provides constant pulling force and it supposedly will never require any adjustments. Well maybe once when you install a new reel with a different peel force. However suitable peel force for the tapes that I checked is in fairly wide range, so I don't think it will be ever required.
I have crashes as well but eventually once a week using it for 2-3 hours a day.
My experience is that one of the SW updates reduced the number ob mismovements.
Do you have any other activity on that PC during usage?
In the first sequence it can still be skipped commands.
I am using the TVM802 since 9 month and never had any crash or wrong movement.
My software is version 2.12, I will not update it since it works perfectly.
your problem may be caused by missing commands over the network, like the well known Win10 problem. However, I cannot understand how a command can get lost in a network.
I can tell you how. Normally two separate commands arrive in separate packets. But W10 can be merging some packets if they are issued close enough. Then the machine does not recognize them. I've confirmed that with WireShark when I worked on reversing protocol.

Do you successfully start machine under free software as a result of reversing protocol ?
No. I've worked out the protocol and made basic application that allows to control everything, but not past that. In the hindsight, the machine has limitations that go beyond the crappy software, so even porting it to OpenPNP would not be sufficient to make it useful.
In particular, the stepper controller is not smooth enough. It creates too much vibration. As a result parts, especially ceramic caps dance on the nozzle which results in frequent discards and/or misplaced parts.
