I recently started working with a v2 dual extruder using Innova-1800 and eSun natural PVA. My hope is to use pva in 2nd(front) extruder as support for my models. I am using one or both the prime tower or the ooze shield when extruders switch. I am growing frustrated that I have not had one of the features successfully build beyond the very early layers of the model. The issue with both is they come free from the bed. The prime tower specifically has an issue because the first layer is PVA and it rarely extrudes material immediately creating partial layer and leaving little or nothing for next layer to build on. excess material begins to build up on hot end getting wiped off by edge of model. I run the Innova at 240c and the PVA I have tried at 210, 200, and 190, the bed I am running at 70c. I am using glue stick. My thought is what would code look like so wipe tower starts with the model material? Possibly, enter sequence in start/end sequence gcode tab. I am no expert with code but I need to try something it stinks to wipe out my models because the features fail.
-On a separate note is anyone using Scaffold support material from E3D? Successful settings for temps, etc. It hasn’t run well yet for me mainly adhesion to the bed and to the Innova-1800.
