Just let them Flop around anywhere tongue

I printed the grills, downloaded  from Thingiverse.
Added plastic screen behind grills, which is also Needed.

You are over cautious. Unless you are flash even if you remove the filament in a hurry it cools solid before the filament fully clears the extruder entry. It would be impossible to get molten filament into those fans.

No, the problem is that filament hits fan-blades and brakes them.
I already had to replace a fan because of that. sad


Well thats just your fault then and I guess you would need them. I move my guide tubes so the filament hangs over the back of the machine when I am changing filament.

this is not a Solidoodle 2 as topic states. also how would filament get into those fans? looks like a duel extruder flash forge type with rectangle bed

Sorry, I thought we were talking about 'adding glass to bed' of printers.
When filament is removed from extruder assembly, it can easily drop down into fan-blades,
the picture is of a CTC-printer, which is similar to the Flash-forge and Makerbot printers.

I moved the left nozzle up, out of the way, since I've only been doing single color objects lately,
using right nozzle.
Will lower it again if needed.

I did do some 2 color objects just to test using both, and they worked great. smile

Yes, That's what I was thinking Also yikes

I was looking at your image and it looks like your right nozzle is higher than the left.. Have you tried printing from it yet? I found the extruder on my right slips and I have a new all metal set to replace both with on their way. That is spring loaded so I can control how much force it puts on the filament.

Did a large print, of a Dremel-bit-holder, with no problems.
I'm sure Glad to not need the **** Clips anymore ! tongue

Only took about 2 days !

It appears that only about 1/3 of the glass-plate is Stuck tho,
the other 2/3 is air-bubbles. sad

I will try a large print today to see how it holds,
with none of those **** clips on it . LOL tongue

then turn bed heater on till it reaches temp (SD2 takes several mins for this each heat up cycle) once temp is reached turn bed heater off and let cool to room temp. repeat this 2 more times and it will stay for long time unless lots of sideways force is applied or pried on and broken. I have printed dozens of items with mine that way and only had to clean or reapply glue stick some times which I use for good adherence of ABS prints. most prints pop loose upon cooling a few had to have razor slid under to loosen which took some glue stick off needing reapplied.
