Re: Filament Storage Practices? - 9 years ago

I've seen a few entries on Thingiverse where people have installed small (25W) light bulbs into the aforementioned 5 gallon buckets in lieu of desiccant. Don't know if I would leave it unattended. I like Werner Berry's idea from YouTube. He uses a large Harbor Freight paint spraying vessel as a vacuum chamber to dry/store filament. Personally, I'm thinking that 3DXtech's Zip-Loc mylar pouches

Re: Looking for advice of organizing wires. - 9 years ago

When I designed my own Delta repstrap, I put the controller and stepper motors on the top. With the stepper motors and endstops all at the top, the only cables that had to run up from the base were the incoming 12V power feeds and the SSR signal down for the heatbed. There is a school of thought that mounting the motors up high is a bad idea due to frame flex and making the frame top-heavy, but

Re: Dual power supply (relay?) - 9 years ago

Mean Well power supplies like the one you linked have trimpots next to the output terminals to adjust the voltage. The spec sheet says that the SE-350-12 can be cranked up to 13.5V, which may make a difference. The big question is how your RAMPS board will handle the higher voltages. I don't use one, but have heard that there's concerns if your voltage exceeds +12.00001 volts. If you can get

Re: PLA in heated chamber - 9 years ago

There is a gentleman south of the equator who lost his PLA-printed Cherry Pi delta printer inside his car on a hot day. My delta printer's PLA effector plate folded like a taco shell whenever I cranked the E3D up for printing ABS. Personally, I wouldn't put *any* PLA near a heated chamber.....

Re: RAMPS1.4 - Heatbed wont heat up to 100C - 9 years ago

If you want to eliminate the controller from your suspect list, just wire the heatbed directly to your 12V power supply for testing. If it can't reach 110C wired directly to the power supply, you know what the problem is.....

Re: smart controller or LCD and separate SD card reader? - 9 years ago

I saw a post by someone that had some sort of shielded cables manufactured for additional length. My comment was only a caution to watch out for problems if you do need to extend the cables - both the GLCD and the SD card extender. I just saw a neat feature last night on the Smoothie web site that I have never seen before. They have added SD card auto-mount with their external GLCD display. W

Re: smart controller or LCD and separate SD card reader? - 9 years ago

Just as an FYI, the current Megatronics 2.0 GLCD piggyback adapter board does *not* have the ability to pass the SD card interface through to the external display. It seems like it is more than just a few pins missing to make this work, as the only people who got it working that I know of are in the German section of this site and they had to modify the Megatronics board to get the proper signal

A better question is what type of power supply is being used? It sounds like it may be functioning at the upper threshold of its output capacity, popping the breaker from running the heated bed at a 100% duty cycle to hold 110C.....

Re: Do I REALLY need an SSR? - 9 years ago

My two cents is to wire the heated bed directly to your +12V supply without the SSR for a test. If it still struggles to get above 45C with no SSR in line, then the SSR isn't the cause of your problem. I can tell you that my 300mm diameter Onyx heatbed (delta printer) took 40 minutes to reach 95C when run from 12V, and struggled to reach/hold 100C when I was trying to hit 110C. I picked up a M

Re: RRD GLCD startup problems with new psu - 9 years ago

How does the voltage on the 24V supply look when you power up the printer? Does that monster supply need a minimum current to help it keep the power regulated and clean? (Some of the ATX supplies need 0.1A.) How clean is the output? I just went 24V myself two weeks ago. The 300mm diameter Onyx heatbed on my printer was taking 40+ minutes to reach 110C on 12V - even with an external SSR. Sev

Maybe I am confused about the part. I was thinking that you were mounting it with the added portion up, lowering your build height by 20mm or so by having the vertical extrusion extend up above the bracket. If your idea was to put the added portion facing down, then blocking the side slots is obviously a problem and your design makes sense just catching the outside slot of the extrusion. If yo

Re: RRD GLCD startup problems with new psu - 9 years ago

On the Azteeg X5, several people have reported that powering a GLCD from the on-board 5V supply causes similar problems. Mine was a coin toss as to whether it would display the Smoothie banner or gibberish. Even if it did boot clean, it would change to gibberish after a few minutes. The recommended fix is to power the GLCD from an external 5V source. I got away with changing the board from in
