Voron Trident

Short answer

The Voron Trident is a fast CoreXY with a direct-drive extruder and an all-metal hot end, and it prints PETG best at a 240 to 250 C nozzle and a 70 to 90 C bed, with low part cooling and a short retraction. The Trident can run PETG quick, and the hard part is the filament: PETG strings when wet, so dry it first. Slow the first layer and these numbers give a clean print.

01 Starting PETG settings for the Trident

These numbers suit a Voron Trident with the direct-drive extruder. The nozzle and bed values track the Polymaker and Prusament PETG datasheets and Bambu’s PETG guide. The retraction and speed tuning are Marqilo starting points for the Trident’s fast, direct-drive setup. Dry the PETG first.

02 How to adjust PETG settings

  1. Dry the PETG

    Run the spool at 60 to 65 C for 4 to 8 hours, then print from a dry box if you can.

  2. Set the temperatures

    Nozzle to 240 C and bed to 80 C is a safe start that melts PETG clean on the Trident.

  3. Keep cooling low

    Run the part fan off for the first 2 to 3 layers, then 30 to 50 percent.

  4. Tune pressure advance

    The Trident runs Klipper, so adjust pressure advance for clean PETG seams.

03 What goes wrong

Most failed PETG prints on the Trident trace to wet filament and too much cooling. Wet PETG strings and prints cloudy, so dry the spool. Full part cooling weakens the layers, so cap it at 30 to 50 percent. A nozzle too cool under-extrudes at speed, which clears when you lift it toward 250 C. The PETG stringing guide covers the hairs.

Frequently asked

What PETG nozzle temp for the Voron Trident?
240 to 250 C. Start at 240 C and move to 250 C at higher speeds. The all-metal hot end handles the full PETG range.
How fast can the Trident print PETG?
80 to 200 mm/s is a safe range for the bulk of the print. Keep the first layer at 20 mm/s and the outer walls slower for a clean surface.
Why is PETG stringing on the Trident?
It is usually wet filament. Dry the PETG at 60 to 65 C first, then tune pressure advance and retraction, and keep part cooling low.

For the material side, the PETG hub explains the filament in depth, and the filament storage guide covers keeping spools dry.
