Hello,
I am rebuilding my Burly, and switching to a Primo 23.5mm.
I have tuned my modified Ender 5 for a good CHEP cube, and extruder calibration.
I noticed that after those cal procedures, I also had to reduce the flow rate.
My parts that accept the 23.5mm are actually 23.2 to 23.3mm. Is this normal? I have NOT actually measured the conduit pipe…it MAY be less than 23.5mm
On another issue, I see that Cura is changing the temperature in the gcode, even though I have all
temps set to 200. I went through the gcode and found 200, 210, 215 and 220. I cannot find why it is
doing this…???
The parts look good, even though I switched to a 0.6mm nozzle and 0.4mm layer height.

No, improvements are SKR 1.4 board 2209 drivers, all metal hot end, all metal extruder, Bowden tube upgrade.
I have not, as yet, put on a direct drive extruder…
I am wondering if the slicer developer has a data model in house based on temperature and volume of material passing through a hot end. It would require more heat to be applied to a hot end to maintain a consistent melt zone for 0.4mm layer height from a 0.6mm nozzle than for a 0.2mm layer height from a 0.4mm nozzle with all other factors being equal.
I’m currently getting all my parts together to build a primo from scratch. I’m using Cura 4.9.1 to generate the gcode from the 23.5mm *.stl files for my Ender 3 pro (all stock).
I’ve printed the feet and 2 trucks so far, the 2 mirrored trucks are currently printing. I’ve been checking the ender every so often, and it always has an extruder temp of 200 with a bed temp of 50. Those are consistent with the settings in Cura.
I haven’t taken my measuring devices to them yet, but the feet slip over my 3/4 EMT conduit with plenty of space to move around.
So far everything looks good on my end. I’ll keep you updated if anything looks off.
