I would like to add an extruder to my CNC mill. I want one that can take advantage of the speed I have available. My current printer can only go 30mm/sec, in large part because the extruder cannot keep up with thicker layers. I want something that can really MOVE the plastic--perhaps enough to do 2...

It just depends on the filament. Some regular filaments are "self extinguishing" (not ABS). Then you have some high end stuff like PEI or ULTEM that has to be extruded at like 350c. It is flame retardant, but very few printers are able or safe to print at those temps.

Probably Dec 25th lol.

Just don't go overboard with these settings. If you are printing 2 outlines for every one infill you are already doubling your plastic flow. I wouldn't go over 120% infill extrusion width to start if you do this. Try also printing at about 75% infill. It is just as strong, especially on bigger parts...

That profile is so out of whack I'm not sure where to begin. 10mm of retraction takes time, it doesn't happen instantly. For every 10mm of retraction you also have to wait for 10mm + 1mm of prime. Printing fast increases nozzle pressure, and the faster you print the more pressure. I don't see a lot ...

Probably need a little more code than that. I suspect you are heating T0 and printing with T1. Look at your extruder setup and make sure Tool 0 is selected and T0 is selected for heater. Remember the printer doesn't just do what it wants, it does what it is told to do. Like a record player, it just ...

PETG hates to be over extruded. When it overextrudes even a little some plastic accumulates on the outside of the nozzle and cooks to a brown gunk. This will eventually deposit a stain onto the printed piece. In short, turn down the extrusion multiplier about 10% to start. So if you are at 1.00 chan...

It will make sense if the supports where not dense. But the last two layers of supports are 90% infill. The bridge layer just make a total mess of the surface because it follows of course the bridge settings (which are not for printing over a solid layer). No, there should be 1 separation layer bet...

It won't make scars as bad if you are extruding the proper amount of plastic. Since that top layer is overextruded about 10-15% the nozzle drags through the high spots leaving scars. Or is there a second nozzle that might be too low? Both will do it, but having a hot nozzle go through over extrusion...

Change 5 and 6 to 100% unless there is a specific reason you need to alter the values.
