Even after upgrading the CW2 to a G2E I wasn't happy with my extrusion. So I got rid of the Rapido UHF with a Lancer.

!!! This only works with G2E without modifying the Lancer Hotend !!!

----------------------------------------------------------------------------------

I bought an AWD Trident from Siboor and wasn't that happy with the Stealthburner Combo. As much as I like Phaetus as a vendor, the Rapido 2 Plus UHF the kit came with wasn't mine. I switched from CW2 to G2E hoping it would get better, and it was, but I wasn't satisfied.

I heard good things from the Lancer Hotend and wanted to try it. I modified the Toolhead Holder, to screw the Hotend in with 4x M3x6 countersunk screws. I made the Toolhead holder one piece to make it lighter, more accurate and save the weight from the screws/heatinserts. I also adjusted the angle of the air outlet to better reach the nozzle.

Print this as you like, preferred on the angry face side with lots of tree supports. Slice and print with Voron standards in ABS/ASA.

You will need an 11mm long PTFE Tube to bridge the gap from the G2E to the Lancer inlet. I found the 2,5mm ID ones for the Bambu AMS work good without much friction. And since the inlet from the Lancer Hotend is countersunk to 2,6mm it works fine. Look for something like this or use Capricorn Tubing or whatever you have on hand:

The Cartographer will be really close to the bed while adjusting your z offset after this change, which will also be really close while touching the nozzle on print start. To prevent this I made a little spacer with 8mm height, to substitute the UHF Extenders, which are around 8,8mm height. You can use this or normal standoffs for like motherboards with m3 thread and 8mm height, or make your own spacer. To compliment that I used low profile screws ( 2x M3x14) like these:

Lancer Hotend Heater needs to be recrimped for use with EBB2209 CAN, but thermistor works fine in TH0 Port. Just comment out the PT1000 stuff.

I get around 30mm^3/s Flow with the Hotend, with 0.4 nozzle and ASA @250 degrees, very consistent extrusion, with a clean finish.
