I do similar except the preheat. It doesn’t matter anyways as the start g code pauses heating of the hotend and bed until the mesh is complete. I sometimes collect the ooze but the purge line usually takes care of that for me and the skirt will catch the rest.Just wondering if anyone else does thing.
Before I start any print I:
1. Pre heat JUST the bed. My reasoning for this is that my hot end can get to 210 real quick, my bed takes forever getting to 60. I let that get close to where I'll be printing.
2. "Auto Home" so the printer knows where it is, then raise the z position up about 30 mm.
3. Start the print - this triggers the prewarming of the bed and hot end. During this portion as the hot end is heating up some filament will start to ooze out. Before the printer "auto home" itself again I grab my pliers and pull off this excess filament. I do this to avoid having it start collecting on my nozzle.
4. Print starts, printer purges the remaining filament that oozes out
Looks like I’ll be going to ERRF this year. My wife offered to ride along even though this is too high on the geek scale for her. I just ordered the bulk of parts for a Mercury One.1 build and I’m stoked. I’ve wanted to build a Voron, but this will get my close with half the admission price.
