Re: All metal Enclosure for Prusa i3 - 6 years ago
I am able to get steel sheets laser cut and bent and even powdercoated at my work. I think I will be constructing a new enclosure in this way instead of using 2020 profiles. If anyone has got some important features in their heads that could be implemented that I have not included in my first post then please come up with your suggestions.by Edvardas - Prusa i3 and variants
Re: All metal Enclosure for Prusa i3 - 6 years ago
I have built a corexy printer a few years ago and put it inside an enclosure. Enclosure was made out of 2020 profiles from Motedis and laser cut stainless steel sheets. Door was made out of glass because I wanted some added fire protection and not have flammable plastic enclosing a printer. Bellow are some photos of it printing parts today:by Edvardas - Prusa i3 and variants
All metal Enclosure for Prusa i3 - 6 years ago
I have had my Prusa i3 for five years and it has got some wear and tear over the years. I am putting an e3d nozzle on it and replacing cracked ABS parts. And next I will be making an all metal enclosure for it. I hope that an enclosure will help me achieve a fallowing: Fire hazzard protection Contain smell Produce even temperature inside an enclosure to reduce warping An easy way to fit smallby Edvardas - Prusa i3 and variants
Re: new to 3d printing - 8 years ago
QuoteSteveRoy QuoteTitan Isn't the ebay folger tech a prusa i3? They call it an i3, but it's more like an i2. An i2 has the motors at the top where as the i3 has the motors at the bottom with a stiffer frame. I think it's a marketing thing. The Prusa i3 is the most popular DIY and kit 3D printer and they would miss a lot of sales just calling it the "Folger 2020" The "Reprap Wilson II" is anby Edvardas - General

Why not put Z-axis smooth rods further away from each other to the corners of the bed? That should make it even more stable.by Edvardas - CoreXY Machines
Re: Foldable, portable CoreXY (Fusebox derivative) - 8 years ago
Looks like you have got a so called Z-banding issue. It is caused by an M8 threaded rod that is not straight. Pitch on M8 rod is 1.25mm and it looks like the repeating banding happens at this distance which proves it all.by Edvardas - CoreXY Machines

I will be using an Ormerod designed extruder and plan to have 3 extruders and a diamond hotend in the future. I will build everything first with a single extruder and then see how best to mount the extra extruders and perhaps a facility to hold 3 reels of filament.

Re: Foldable, portable CoreXY (Fusebox derivative) - 8 years ago
What kind of nozzle are you using? 28mm3/s is something that only a Volcano should be capable of melting. Usual nozzles have around 10mm long melt chamber. I can extrude PETG up to 10mm3/s and more without extruder skipping but e3d v6 lite just can not melt sufficiently above 6mm3/s (keep in mind that PETG requires more time to melt than PLA) And 3mm is not really efficient at high volume meltinby Edvardas - CoreXY Machines
Re: Z Axis Belt drive - 8 years ago
At the end of this thread you can read my experience of belt driven z-axis: I could also add that I have experienced a few milimeters of belt stretch after a few kilograms of plastic printed. I hope it is just an initial stretch and belt will stay at where it is at now. Another conclusion I have made in my head is that both screw and belt driven z-axis can deliver great results or be a disastby Edvardas - General

Re: CoreXY sensitive to belt tension? - 8 years ago
Quotebani so if corexy is not a high speed design, then why would anyone use it over ultimaker type design? I doubt that an ultimaker's gantry could carry an extruder without a lot of deflection on those smooth rods. So wanting a X-axis mounted extruder would be one reason. And some people just prefer to shave off all the possible weight. For some people losing 400 grams (weight of a motor) offby Edvardas - CoreXY Machines
Re: Which core XY should I build? - 8 years ago
In my experience even half decently built X-Y axis work great. Z-axis is where you should put your attention at.by Edvardas - CoreXY Machines
Re: Foldable, portable CoreXY (Fusebox derivative) - 8 years ago
Do you notice any under-extrusion while accelerating or over-extrusion on deceleration? I have noticed that this is a problem if I come close to extruding 10mm3 of plastic per second (which is widely considered the maximum). And with my 0.6mm nozzle and 0.3mm layer height that is already a very low 50mm/s maximum printing speed. Moving at 30mm/s gives great results and that is 6mm3 of plastic eby Edvardas - CoreXY Machines

Re: CoreXY sensitive to belt tension? - 8 years ago
I guess that is because you are planning to use a bowden. I am a fan of direct drive and more than half of the designs I see have carriage mounted extruder We see what we want to see. Oh and this comes from looking at designs on thingiverse.by Edvardas - CoreXY Machines
Re: CoreXY sensitive to belt tension? - 8 years ago
Nope. I tensioned belts to where they are neither too tight nor too loose and did not feel a need to do any further adjustments. That worked twice. Although I think I know what he is talking about. He has a heavy direct drive extruder and a cheap smooth rod system. It all weights above 1 kg. Mine is even heavier and if I print at higher speed I can see circles looking like a hex.

Re: Excelvan ABS and PLA question - 8 years ago
Maybe your acetone is some kind of safe 21st century mixture that barely works? Try braking a piece of it. If it whitens then it should be ABS. I have not had a problem leaving ABS outside the bag for months if not half a year.by Edvardas - General

Re: Glide mount - 8 years ago
I am not sure if linear rails can be mounted in any position but geometry vise you want a smallest distance between a rail and a tip of the nozzle. The higher the distance (arm) the higher stress (or oscillations) you have on your construction in case there is any force acting on the tip of the nozzle (like hitting a curled up plastic on the printed object). Based on this I would go with a desigby Edvardas - CoreXY Machines

Re: 0.0mm or 0.1mm - 8 years ago
Practically it does not matter. You can use 1mm thick feeler gauge to level the bed. Then you use experimentation to find a gap for an optimal adhesion. So if you are using 0.2mm layer height you might have your nozzle 0.1mm or 0.12mm or 0.18mm or 0.3mm away from the bed in order to achieve proper adhesion that allows removal of the part without it warping while printing. And this even depends onby Edvardas - General
Re: This engineer claims 100 grams direct extruder. I want one
- 8 years ago
What do filament manufacturers use to track freshly extruded filament's diameter? I think I was watching a video of extrudr.eu manufacturing process where they had a live graph of filament diameter measurement as it was being extruded. Whatever they are using must be working and it should be possible to implement unless hardware is massive.by Edvardas - General
