I’m trying to aspirate and dispense liquid using a Tecan Freedom EVO. Aspiration is working fine but I’m running into error EVO_EVO_013_039 on dispense (see the screenshots below). I tried lowering the dispense speed as suggested by the help menu, but this did not change the values in the firmware log and also did not resolve the error.
Does anyone know how to resolve this error? Please let me know if you need more information.
Hi, the problem solved. It is indeed a speed problem but the actual problem we had was we were using a temporal liquid class with “>> LIQUID_CLASS_NAME <<” on it, so whatever speed we changed in the liquid didn’t become effective. After changing it to “LIQUID_CLASS_NAME”, it works.
As an aside, those customized liquid classes whose names appear flanked by >> and << in EVOware are handled poorly by the Export Import tool and should be avoided if scripts will ever be transferred between robots. It’s much safer to create a new custom liquid class instead.
