Tecan Fluent not saving TeChrom dispense parameters

Hi all,

We have a weird issue that has popped up when programming our Tecan Fluent with Robo Columns, aka TeChrom dispense steps.

When entering new parameters into the TeChrom dispense steps the parameters don’t save.

For example:

  1. We open the script
  2. Change the dispense parameters to 1000ul sample dispense on the TeChrom step, overwriting the previous parameter of 0ul
  3. Hit save
  4. Close the method
  5. Re-open the method
  6. The OLD TeChrom parameters are still there of 0ul sample dispense

We have tested this in small test scripts as well as our full method. Restarting fluent, the tecan itself, or the computer has had no effect.

Is this a common occurrence for Tecan Fluent? How do we resolve this? Happy to attach a gif of this as well if that helps!

Thanks,
Colin

FYI for anyone that runs into this, this is a bug in this version of software. The solution from Tecan was:

" A possible workaround would be: Program script in a location where context-check reaches it (e.g. line 1) and then move the script command into the If-Else branch.

​

As the script is quote long, it takes a while that the context check info: “this command has not been hit by last context check” appears. However, with default settings line 324 is not reached with the context - check.

For me the workaround - copy the line to e.g. the beginning of the script, change the values, save them and copy them back - worked out. But you need to be careful that the destination labware needs to exist (at the beginning of the script the variable “RobocolumnType” = 0."

Obviously not an ideal work around, but this allows us to get this software running.
