QuoteToxic0n Whats is the advantage of belted extruders? Lighter and more precise? I just thought it would be quieter I never tried the gears though.by msaeger - Prusa i3 and variants

QuoteBert3D Quotemsaeger with a belt instead of the gears. If you don't want to try and build it from scratch this guy is selling it ready to go. I bought a different design from him and it was good. Doesn't that extruder design cut off some of the vertical print height? It would seem better to have the motor off to one side or to the front. I get 150MM with no Z motor extensions or anythiby msaeger - Prusa i3 and variants
Re: Extruder bouncing over previous layer - 8 years ago
That first layer looks over extruded or you are too closed to the bed. Do you have the slicer set to extrude more on the first layer? silc3r default is 200% on the first layer which works fine for me but you can try changing it. You may just be too close to the bed.by msaeger - Prusa i3 and variants
Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 8 years ago
Quotemarc2912 I noticed someone else mention it on here. I have an E3D with the stock extruder. I had to remove the aluminum block that sits under the extruder that the heat block screws into. I was going to upgrade my extruder to this from ebay but the block isn't removable and I won't be able to attach the hotend. What are people running with an E3D that is NOT a bowden extruder. withby msaeger - Prusa i3 and variants
Re: Layer cooling fan - 8 years ago
I printed out this one and tried it using an axial fan. All the people that say axial fans can't deal with the back pressure are right, I get no air coming out of the hole at all. I am not going to waste any more time on ones that use an axial fan.by msaeger - General

Not sure if you can get one but I got this plate and my bed is now flat. I had the same issue as you before I added this.by msaeger - Reprappers

What does the other end of the tube look like? The end you are showing just looks like you could break it off and drill it out at the worst case.by msaeger - Prusa i3 and variants
Re: Layer cooling fan - 8 years ago
Quoteorictosh Upon my Ormerod 2 I switched from the 40mm axial fan to 75mm x 35mm radial fan, which gave good results in cooling the print. Also found this post about short layers (time needed to complete the first layer is too quick to provide a good base for the next, ends up looking like "Ice Cream" ) in which various fan duct and shrouds were tested. Also give links upon page to the STL filesby msaeger - General

Re: Layer cooling fan - 8 years ago
QuoteJamesK Yes, like most things with 3d printing it's not completely straight forward. You want to avoid the fan blowing on the hotend as it will drop the termperature pretty significantly if you're not careful. A fairly well directed jet of air targeted just below the nozzle is useful for bridging, but it's prone to being very dependent on which direction the nozzle is moving at any time. A moby msaeger - General
Re: Layer cooling fan - 8 years ago
Quotefrankvdh I recently switched from an axial to a radial filament cooling fan, and I'm very happy with the result... a huge improvement. Remember to only turn it on after the first layer is printed. What duct do you have on it? I don't have any duct on mine (yet), and have it pointed vaguely at the nozzle tip, from about 30 degrees up. When then fan turns on, the hot-end temperature drops byby msaeger - General

Re: Layer cooling fan - 8 years ago
So I have the fan now and have temporarily mounted it just for testing but I am not really getting good results. I am getting worse layer adhesion and it's not really helping with overhangs and bridges. I am guessing the issue is I don't have it aimed at the right place but where should I have it aimed?by msaeger - General
Re: Power Supply Woes - 8 years ago
QuoteNate523 Thanks, Its a china made psu, so one cant expect much I guess. I have contacted them but it will take weeks for them to send me a new one. Thought I could use my old PC psu, but the paper clip trick isn't working on it so I'm suspecting it is a newer PSU that doesn't like that kinda stuff. I might just have to take the thing apart and see whats up. Use the ATX one I just bought a neby msaeger - General
Re: Radial fan - 8 years ago
I found a 50x15 one in an old piece of electronics in the basement so I am going to see how that one works. I hooked it up to 12 volts and I am thinking it may be too loud but maybe during printing with it not running at full speed it will be ok.

Layer cooling fan - 8 years ago
I want to get a radial fan to use for a print cooling fan. Is 50mm the smallest they come? That seems pretty big to be hanging off the carriage and I swear I have seen really tiny ones.by msaeger - General
Re: Folger Tech 2020 i3 Printer Kit (Official Thread) - 8 years ago
Can someone tell me where I would connect a print cooling fan to the ramps board so I can control it? I mean a layer cooling / print cooling fan not the fan on the cool block. Google is giving me mixed results. Edit: After trying a couple places I found D9 worked.by msaeger - Prusa i3 and variants

Quotejhitesma Tried printing with PETG again tonight for the first time since swapping to the metal extruder. Not going so well. About 15 minutes into the print my extruder stepper starts clunking and it acts like it's clogged. But I think it's actually the stepper motor overheating. Checked it and it was over 60c. I've never seen it over 45 before and usually it's closer to 37-40. I'm thinby msaeger - Prusa i3 and variants

Re: Working then not? - 8 years ago
Which part exactly are you cleaning to get it to feed? What material are you printing? If you need to clean the threaded tube I would guess you don't have enough cooling on the cool block.by msaeger - Prusa i3 and variants

Anyone using the openbuilds v-slot stuff notice that the wheels are wearing? I am seeing some wear and some black particles on the rail. Everything still feels tight so it's not a lot yet. Just wonder if this is normal or if I have something adjusted wrong. I did recently loosen the eccentrics a little because I was feeling the build plate wasn't moving freely enough and I don't know if this is fby msaeger - Prusa i3 and variants
Horizontal holes - 8 years ago
I am trying to print this part The issue is when I get to the point of bridging the horizontal holes the edges over the hole have curled up enough that the nozzle hits it and causes mis-registration and ruining the part.

Quotemarkts Quoteanimoose Quotemarkts I have the E3d V6 Lite installed and it seems to be printing well. I still get some clicking/missing from the extruder. I remember I had to play with temperatures with the stock hotend, so I probably have to do that again (now that I'm printing at 195 instead of 175). I didn't replace the gear that grabs the filament. They seemed to be the same size, anby msaeger - Prusa i3 and variants

I'm looking at the calibration instructions and it says to fold paper in half and run it between the nozzle and plate - and adjust as needed.

Re: Stepper Motor Clicking - 8 years ago
I would remove the motor from the extruder then try and run it. Then you can try and stop it with you hand and see how hard it is to stop.by msaeger - Printing
