X Axis Nozzle Wiper for Ender 3 v2

Settings used:

• Print height : 0.2 mm

• Perimeter wall: 4 or 6

• Top wall: 5 or 6

• Bottom wall: 4

• PETG preferred

I am mainly more active here on my Cults: https://cults3d.com/en/3d-model/tool/x-axis-nozzle-wiper-for-ender-3-v2

but I will try to get active here..

(The speed/feedrate set on the Nozzle wipe; wont make any difference, unless you change the max acceleration on your printer/firmware) DISCLAIMER: Please be advised, research your machine carefully, the drawbacks are; if you are not careful, given the new speeds.

• Your hot-end might collied with things on your build plate/printer/point of travel, if left unattended during Homing of Axis

• You will wear out your belt or v-rollers much faster if not calibrated/tightened properly by manufacturer specifications.
  

(On ender 3 v2 with Mriscoc Firmware, I change my max speed and acceleration, both from default; 500 -> 650 on the X stepper only.) here is a guide by Prusa, Knowledge Base: https://help.prusa3d.com/article/adjusting-belt-tension-mk4-s-mk3-9-s-mk3-5-s-mk3-s_112380

Here are your Physical Maximums that needs to be set on your Ender 3/v2 (please do not change if you have changed anything on your X/Y travel path on min -> max)

• X = 251 mm (you can try to verify this by sending your Hotend to 230, then try to get close by 1 mm. your M5 screw threads, behind your Hotend shouldn't hit by the end bracket/attached to the 4020 extrusion. )

• Y = 230 mm (shouldn't hit your stock tensioner)
  
  

UPDATED (07/01/2026) : Added bypass for Nozzle wipe speed so you wont go thru the trouble of unlocking. it will revert back to your printer max limits after the g-code nozzle wipe.

REMEMBER: If you have a stock ender 3 series, your X axis should be maxed around 251mm. that is before one of the 3 bolts, behind the hotend plate smashes on the Z axis gantry/beams.

- Kindly Verify your max limits on your Printer first then, run the gcode with a sliced test cube before.

Thank you.

G-code: Copy below this bracket and test on a small print. cut in half test cube.
