Topic: Suggestion request for nozzle size, 3-4 to drill.

So my main concern is for 3mm pla, I use the 3mm melt filter for abs and get great results on both vertical and horizontal with a slight slope. Pla comes out around 2.2mm on the same setup with 3 fans, i've drilled one for 1.9mm and get great results on vertical with winder for pla/abs coming out around 1.8mm, but might want to drill some around 1.8mm.

have 3 undrilled nozzle's i'd like to drill for pla and other materials that have a slower cooldown time.
any suggestions from experience would be great at this point before i just go drilling away.
will be using a drill press at work so i'll have to pickup the bits first and will post results once there in.

feel free to post any suggestions for all sizes you'd like to see as well.

Re: Suggestion request for nozzle size, 3-4 to drill.

Standard 3mm nozzles are drilled to 2.77mm. I'd guess 3mm or 3.2mm would get you in the ballpark if you're currently seeing 2.2mm.

It also sounds like you're extruding a bit hot or have quite a large loop for the winder if you're seeing 2.2mm on a stock nozzle.

might be a bit hot on the pla, but also using beta speeds on the motor, the loop is quite large and feeds backwards behind the vertical extruder to the winder.  limited workspace

that dimension on the stock nozzle will help as a starting point. thanks

Re: Suggestion request for nozzle size, 3-4 to drill.

search for conversion chart for orifice gauge, number, letter drill bit sizes and they give MM and inch sizes of each drill bit so you can buy correct bits needed. or buy complete sets like I have from when I used them in my trade career. for LP and Natural gas burners in HVAC and appliance service. can also find gas flow charts for them using various pressures.
