frankenstein-duct's Issues

Creality Spider Hotend not fitting

Hi,

I built the BMS7 version for the Orbiter v2 ince it says that one can be used for the Spider Hotend.

However I had to make some serious modifications in order to make it fit:

• the upper of the 2 mounting screw holes is not fitting, needs to be placed more up left (at least on my Ender 3 V2 that is)
• the right carriage mounting hole needs to be placed a little more to the right it seems (also maybe related to my Ender 3 V2)
• the spider Hotend is too big, the right side where the BL touch can be attached needed to be cut off by 3mm
• the fan guide is also much too deep for the Spider, had to cut off like 5mm to make it fit.

The upper issues I could correct by drilling a bit, but the one below could not yet fix easily:

• the orbiter sits too far back if used with the spider hotend, around 3-4mm
• I have a short PTFE Tube connecting Orbiter and Spider now, but that one is now seriously bent back

The extruder works but I am uncertain if that bent PTFE tube affects performance as also the filament then has to travel that cruved path.

Some other issues (maybe not supported):

• I use a CR touch, but the mount is much too high if used with the spider hotend. For now 2 M4 hex nuts used as spacers do the job.
• I have a Sunon 5015 fan but the duct is much too tight fitting when the screws are mounted and I broke it easily (not the best way of attaching, maybe that could be enforced? For now I simply glued the whole duct directly to the fan which works fine it seems.

Besides that I really like the FrankEnstein-Duct :)
