Pre Print nozzle purge

Recommended Posts

Hi,

I have 4 UM2 printers all running on the same version of firmware yet they don't all do the same thing when it comes to their pre print routine.

Once the bed and nozzle have reached temp and the build plate rises to begin printing I am seeing the following on different printers

1. The nozzle will purge (dispense material) onto the front left hand corner of the glass and then printing begins

2. The nozzle will purge while moving to the start position of the print job

3. No purge will happen

Is anybody else seeing get these differences while running the same version of firmware?

Is this a friend ware issue or does this get setup somewhere else?

Is this with the same GCode-file? Are files prepared with cura, if so, which version and have you set the GCode flavour to UltiGcode for all machines? Have you tried doing a factory reset on the printers?

 

Different GCodes but I have never setup these in cura outside of layer thickness etc.

I am using two different versions of cura depending on which laptop I use. I will take a look at the setup of both and report back if I need more assistance.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
