I use synthetic bearing grease made by valvoline. It has not effected my ABS parts at all. however I do not use plastic bearings yet. The grease touches the plastic carriages that hold the bearings. It did not effect it in 8 months of exposure.by jaguarking11 - General
I had 1/4 of a roll of chinese filament from last august. I just finished it a few days back as I was calibrating my printer. It sat open since I opened it. I can say that while it is more brittle, it had no problems with clogging. I suspect your retraction settings may be to blame. I run 3.5mm retract @ 200mm/s on my bowden fed delta. No issues feeding it. I ran up to 4.5mm of retract on it befoby jaguarking11 - General

I have the source code for the printer files. With that said, I may just build and ultimaker style small printer with a build volume between 150mm cubed and 200mm cubed.by jaguarking11 - Tantillus
Quote3DPrintingNoob Okay now I don't know what is considered "heavy" for a build surface. I am just assuming that it would be heavy since it will be much larger than the usual build platform. The total mass of the build platform, beds included, would most likely come to approximately 15kg. Is that considered "heavy"? What is the maximum weight that a stepper motor can lift effectively with no errby jaguarking11 - General
I am planning on building a spin off of this printer to sit on my desk. My delta printer is huge and needs its own table. This sized printer would be great for small parts.by jaguarking11 - Tantillus
Well I am about 2/3rd of the way done with the heated chamber. Check out my blog for more details. I completed all the ABS parts that needed to be built and designed. The new carriages and effectors are also made of ABS. I did some small tests with ABS in boiling water, it really did not harm it. So I am hopefull the temps will be within reach.

I am curious. My old not so good extruder with 1.7:1 ratio was able to feed my 1.5mm bored j-head to over 30mm/s. The amount of material pushed was huge, I had more problems with the j-head cooling too fast than the speed of extrussion. I was running my j-head at over 240c and saw temperature dip into 210c when it was moving quick. I suggest you increase the temp on your hot end to at least 240,by jaguarking11 - General
One small thing to keep in mind. Don't expect to print with a normal nozzle. At this point 1.0 or larger nozzle is the only way to go. You probably need more thermal mass for such a large nozzle. In my experiments it's possible to print with a 1.5mm nozzle with 1.75mm filament. The output will be in the 1.8mm range. 500 micron or taller layers Need to be extruded.by jaguarking11 - General
I agree on the sentiment. I put in a 3mm alu heat spreader on my glass with thermal paste interfacing the glass and the heater. After 300+ hours of printing it is showing no signs of fatigue. Although the hardest I have pushed it was 120c.by jaguarking11 - General
I do not have set plans as of yet. I am planning on throwing together some stl files for the 3d printed parts and some PDF files for the base and top.

Honestly, For under 1k I have built my delta. It will now do 12x12x16inches+. It took me a while to get there though. With all that said, you have kids and want to keep the printer indoors? I would suggest you build an enclosed printer that has a venting fan built in, so you can vent out the chamber before opening it. I would not want my kid to breathe in PLA or worse yet ABS/NYLON fumes. You sby jaguarking11 - General
I think I can get away with using smooth rods on a larger envelope as long as I can cut threads at the ends of the rods and torque them. If you stretch them 100-200 micron the tension they should reduce the flex dramatically. As long as the strech is within the spring stage of the rods and not on the plastic/deformation strength.by jaguarking11 - General
As for heavy plates. For me I am comfortable with Delta printers. If properly designed you can use some very heavy plates and use them under compression. You need to design a frame that is stressed and not simply placed. Using the materials in the proper spots will yield a exceedingly strong frame. Once you have that. You can design a light weight moving mechanism.by jaguarking11 - General
I think over engineered is better than under engineered. 3/4 inch steel plate cut to my requirements would be ~200USD which in the grand scheme of things would be a spit in the bucket vs the liner motion parts. Resonance during printing needs to be dealt with, the best way to deal with it is to add weight and stiffness. One more thing, the larger a printer gets the higher the error rate it willby jaguarking11 - General
I was thinking about this the other day but with a delta printer with a build volume of about 60cm/60cm/60cm the Height of the printer would be nearly 1.3M at the minimum. Probably around 1.5m in height. Then I sat down and thought about the stability of the frame. As far as I can think through. I would need some large steel plates for both the top and the bottom. Around 1.5-2cm thick. Then somby jaguarking11 - General
I never bought a full printer. If I had 1500USD to invest I would probably build 2 or 3 more delta printers so I can prototype faster or even produce more. I self built my own and to be honest I am in absolute love with it. Quality, speed, size and price were right for me. I think I invested about 700USD with mistakes and extras all in.

I figured I would throw my design out there as well. Its a belt drive extruder. 2:1 ratio. It only works with bowden and 1.75mm out the box. Its designed around the premise of having the retraction speed of a direct drive, with no slack while being stable at pushing filament. At the present time I have got between 150-175mm/s with my .5mm nozzle. It shows no signs of issues at that speed. That isby jaguarking11 - Delta Machines

Quotejonnycowboy I'm not too worried about the gear ratio. I know others are using geared steppers with similar ratios to drive the extruders. Because they are doing it does not mean it works well.... Ideal ratios should be calculated properly with retraction speed being a priority. My 2:1 extruder can drive my printer at over 150mm/s with .5mm nozzle and .3mm layers.by jaguarking11 - Mechanics

I disagree. Microcenter in Queens has a decent turn around rate for their filament. Its close to my house and I go there almost every week. I usually pick up a kilo every time I go.
