Topic: More jamming with cover on?

So I have printed a few things and <3 my SD2. Made some glass beds out of the gate and they make printing EASY (though getting the vertical adjustment right was a bitch). But Does anyone else have more jams with the cover on? I suspect it is the angle the filament is coming into the extruder feed, but would really like to use the cover when printing. If I remove the cover and have the filament come in straight from the top (over the back of the frame), no jamming, while if I have the cover on, the advance wheel will grind the filament to dust, which requires dismantling and cleaning and interrupted prints.

Thoughts?

Re: More jamming with cover on?

Hello ErroneousBosch,
I didn't have cover but even with out it for me the original position obliged the filament to have a poor curvature.
That is the reason why i change the position of the filament.
See : thingiverse.com/thing:36931
Since this time i have no more problem with feeding.
But if you want to keep your top, this solution is not yours. But may be you'll can try this solution : .thingiverse.com/thing:34887

Re: More jamming with cover on?

I am not having any jam problems printing with the cover on.  However, I am noticing that the filament is constantly rubbing against the powder coat finish which is creating a fine powder coat dust inside the printer (I am noticing the dust building up on the fans).  I am not sure if this will be an issue in the long run or not...

I have printed one and it is installed on my printer.  I'm more concerned about the filament that is still rubbing the top of the case.  I have only had my printer for a week but there is already some noticeable wear on the powder coat from the filament rubbing.

Oh ok.  What about some kapton tape on the underside of the case top?

I'm going to try that.

Print and fit that bush, I did and have had no problems.

Also, I have found having my spool on a holder about 1ft behind the printer creates a more streamlined path for the plastic to follow, if the plastic is directly behind the printer it has to bend 90degrees to enter the machine, with it sitting back a bit its almost horizontal when it enters the case.

Re: More jamming with cover on?

I printed a set of these http://www.thingiverse.com/thing:34887 (Solidoodle Case Riser)

A little flimsy I must say but a good proof of concept, I was printing with the crystaline clear which is very brittle and this allowed me to use it without it snapping before going into the extruder.
I think an improved version of these would be the go at some stage.. still using mine though.

Re: More jamming with cover on?

I was wondering about buying a clear plastic bowl with a cover lip almost the entire size of the top of the SD cover, cut a hole in the top of the metal SD cover and a smaller, 3/4" hole in the bottom of the plastic bowl. I would have the lip of the bowl just fit in the hole in the metal cover and put a rubber washer in the hole in the bottom of the bowl.

Basically this would create a clear plastic dome on top of the Solidoodle 2 metal cover giving distance to the head and a more smooth curvature to the filament from the spool. The large bowl rim at the metal cover would allow the end to follow the extrusion head without any binding.

You'd probably do better with a pyrex glass bowl/square pan. Or even just use a metal pan as essentially an extension.

Re: More jamming with cover on?

I keep the top on the screws that normally hold the case on...I have had 1 bad clog (my fault... retracted a bunch and let it sit.) so you could very well be correct that is is causing more clogs...I know it created way more dust...my #1 idler arm could help this with it's extra deep bite...the motor will bind before the filament slips.
