Print Time Estimate for Dual extrusion


Recommended Posts

Posted · Print Time Estimate for Dual extrusion

Hello, I am curious to know how, or if, Cura accounts for the time taken to switch nozzles/tools on their dual extrusion printers, and incorporates that accumulated duration into print time estimates.


Print time estimates are very accurate for all of my dual extrusion Ultimakers, although a nozzle switch had to maybe be sub 5 seconds(?). The Problem however: I have a Toolchanger printer that picks up / drops off tools, and runs a purge and wipe sequence every time a new tool is called, this sequence takes apx 18 seconds, so it can easily throw print time estimates off by several hours.


I am thinking if Cura already accounts for a predefined nozzle switch time for Ultimaker machines, then I may be able to edit a value to get a better time estimate on a custom machine profile. I have had a poke through the various files in definitions but nothing jumped out at me.
