My comment was meant for Swiss3Dc and the heatsink as V2 has screws from the bottom which is needed for the Syarlex DHB. I own the OnXidian and love it, I want to get one with a 0.6 nozzle for CF and GF. I know 0.4 works with both but 0.6 is recommended. I saw a video the other day in ABS GF from Bambu. Looks like it negates the need for any heating chamber for larger prints were micro cracks tend to form and it’s 30 bucks from Bambu. ABS really benefits from a heated chamber but not modifying my P1 and honestly they need to reach around 100°C to be effective. QIDI sells them but 300W just for the chamber heater power wise. Ok don’t print enough engineering filaments for that. I think X1E only gets to 60°C. The guy on YouTube was trying to print an engineering part that had to be completely flat. ASA and ABS from Bambu on X1 didn’t work but ABS GF worked perfectly. CNC kitchen also did a really good video on this. Anyway, I’m way off topic now.
I do have a chamber heater on my X1. Unfortunately you run into heat creep issues when you go above 55c as the hot end cooling it not sufficient. I assume its the same with the X1E as they share the same hot end and cooling fan design. Also Bambu has a few suppliers for the hot end fans, some are 0.2a and others are 0.4a. With the weaker one you run into heat creep even earlier then 55c.
I can easily see heat creep being an issue, the part fan is a non standard size 5015 fan (at least the exhaust size) so no fans above the cooling fan, which is a pretty weak 2510 fan (at different amps) and that’s an issue. I did take a quick look at QIDI’s site and it’s 65°C even for their newest ones which is more than enough for consumers, in fact they are having a sale and all I will say is I wish I had 800 to spend as they are always extremely well reviewed printers. They make 3D printers for businesses doing prototype printing anyways and I don’t think the X1E is in the same league. I don’t think the X1E is that great when the first thing they say on their page comparing it to the X1 is network features, supporting better security protocols and having a LAN port, not needing Bambu Cloud. With zero cooling design changes and the ability to print at 320°C and possibly the bed doing 110°C, I wouldn’t be surprised if heat creep was present at 60°C.
I’m not a fan of Bambu changing or mixing and matching parts when it comes to power. X1 page still says 40W ceramic heater so depending on where and how long it’s been sitting around it may be 40W, maybe 48W although I’m guessing most are 48W by now but how do you know? At least not without the equipment (and knowledge) to measure it. The cooling fan is a pretty big deal so swapping 0.2 amps to 0.4 amps is a pretty significant difference at 5V and makes more of a difference than using a 60W ceramic heater IMO. Not sure how much wattage difference that is but it’s significant enough to make a difference.
