Re: Waves in the build? - 10 years ago
The only thing I can think of is plastic flow, slicer software or a configuration issue. Those are the only things that haven't been ruled out entirely. Printing an object that transitions from a wide layers to narrow layers like a cone would tell you whether its every x mm of z height or a plastic flow depending on if the bands are spaced evenly on the cone, but you'd have to waste some fillamenby TheTechnicalNoob - Delta Machines
Re: Waves in the build? - 10 years ago
Check the frame for play, loose belts, loose pulleys, loose bearings, loose joints in the arms. Check the heck out of it It could also be a plastic flow issue. If your hobbed bolt was not built properly and is eccentric it can cause this, but I doubt it. It may be worth checking if you've tried everything and have run out of things to check. If it's a plastic feed issue you'll get a wave eveby TheTechnicalNoob - Delta Machines
Re: What's your favourite slicer - especially with overhangs - 10 years ago
I've tried Slic3r, skeinforge and Repetier. I prefer Slic3r. Skeinforge is super complicated to use. Repetier was good, but a little arkward at times. Slic3r was just that much more intuitive, well documented and clear. The latest slic3r has had some good improvements recently. I'd recomend getting the latest version and reading the release notes to see what has been improved. The latest had a heby TheTechnicalNoob - General
Re: Shifted layers for unknown reason - 10 years ago
Layer can sometimes shift when a stepper driver gets too hot and pauses to let itself cool down while the software still thinks the motor is still moving. But when that happens it usually doesn't correct itself like in the second picture. Check simple things first (loose belts). Have you got it sorted yet?by TheTechnicalNoob - Mendel90
Re: 3D printed model plane parts - 10 years ago
For such speeds one would think that swept back wings are required. As is a tiny touch of elevator up or down and the resulting G forces would really test those wings. In that case, you'll enjoy this video: They get their RC plane to go 116 miles an hour. Fast.by TheTechnicalNoob - Look what I made!
Re: How to determine MGN12H rail length for Scaled Kossel Mini - 10 years ago
600mm version has 400mm of rail meaning that 200mm must be ends and other stuff. 750mm version: 750mm - 200mm = rail lenght = 550mm Using that logic you'd need a 550mm rail.by TheTechnicalNoob - Delta Machines
Re: New Own Design Printer 'Cherry Pi' - 10 years ago
It might pay to check if its related to the resolution of the prints. If a circle has 20 segments, thats pretty blocky and easy to process, but if a circle has 5000 segments, the arduino is going to stutter as it pauses while it processes all that data while its trying to move in a circle. If its resolution that is the issue then commands like G1 Y100 shouldn't be an issue as it is simply sayingby TheTechnicalNoob - Delta Machines
Re: ACCURATE_BED_LEVELING_POINTS? - 10 years ago
Are you sure you set the variables correctly in the configuration.h? Might pay to double check. When I set some odd number in the config (say a negative number for the number of extruders) it will throw some weird errors. So double check your config.by TheTechnicalNoob - Delta Machines
Re: Printing accuracy or printing quality - 10 years ago
FYI Slic3r is known to produce slightly small holes on everything so I wouldn't use hole size as an calibration indicator.by TheTechnicalNoob - Printing
Re: Printing accuracy or printing quality - 10 years ago
When the nozzle size = the extrusion width I find I get very weak layer bonding. The Triffid Hunter's calibration guide on the wiki says its should be fine but my results say otherwise as the layers are very weak. When I calibrate for nozzle size = extrusion width it puts out too little plastic and as a result the layers are not bonding properly and so would recomend that you calibrate with a waby TheTechnicalNoob - Printing
Re: Can't connect - 10 years ago
What is the baudrate set to? My arduino won't work with anything over 115200. Btw if you change the rate it has to be set the same in both the firmware and the interface.by TheTechnicalNoob - Mendel90
Re: New Own Design Printer 'Cherry Pi' - 10 years ago
Quotehercek Other than that, I do not really see why people consider (non-removable) z-probes so usefull. I have one too but it is removable. I used it for the intial calibration. And I used it once more for calibration when the diagonalRods/carriages/platform were changed. Otherwise there was no need for it. So you managed to store the bed leveling data in the eeprom which eliminated the need foby TheTechnicalNoob - Delta Machines

Many lasers into one, by means of fiber glass - 10 years ago
Here the article describes how many lasers have been combined into one by means of fiberglass rods. If this works out to be practical perhaps this could be a way to use fifty 0.2watt dvd lasers to form a 10watt sintering laser. Anyways, just an idea.. I just wanted to throw this out there.by TheTechnicalNoob - MetalicaRap

Re: Delta hot end keeps melting plastic body - 10 years ago
Quoterm2014 Quotegmh39 Yea that definitely sounds like a PID issue. It sounds like you are WAY overshooting your target temperature. I am still have a problem, when M303 C8 S100 it on pronter face it returns- Bed auto tune fail, temperature too high. Any thoughts advice on this? In the code it is set that if it goes 40 degrees higher than whatever you told it to go to it will abort. In the maby TheTechnicalNoob - Delta Machines
Re: Bowden strength question - 10 years ago
So the stepper motor doesn't have enough power. You probably need to turn up the amps on the stepper drivers. The procedure for which can either adjust the little trimpots on the stepper drivers, or through software depending on your board. Is the J-head hotend a chinese clone? I've heard they can jam often, whereas the original j-heads from hotends.com do really well.by TheTechnicalNoob - Delta Machines
Re: Has anybody tried 3mm filament in airtrippers filament drive for rostock? - 10 years ago
One geared extruder later and it's printing much better. It appears my prints have also become more accurate, which I think is due to better plastic flow control. At least the direct drive was enough to get me repstrapping. From here its only going to get betterby TheTechnicalNoob - Delta Machines

UPDATE: My PLA and ABS arrived in the mail today The PLA prints without eating into the PLA or skipping with the current setup as posted above in the picture. Although probably not too well at higher speeds.

Re: Sextupteron - 10 years ago
Quotehephaestus Quotebobc I am currently testing a 3 extruder board for Arduino (RAMPS-FD ), and soon a 6 extruder extension board (EXT6 ). So that is 11 axes and 1 extruder, or 3 axes and 9 extruders depending on configuration, or any combination in between. So if anyone wants to build a sextupteron, I would be happy to provide a beta board and firmware help, in order to help development. You wby TheTechnicalNoob - Delta Machines

Re: Current best version of Marlin for a 3DR or 3DR Simple? - 10 years ago
The only differences I have found are that Erik's Marlin firmware uses bed leveling in a square pattern, and Johann's uses bed leveling in a more circular pattern (or so I've heard and seen on youtube). Or even better just head over to Richrap's blog and read his firmware setup guide for the 3DR:by TheTechnicalNoob - Delta Machines

Re: RepRap Tricolor Slave Motor Extruders not Moving - 10 years ago
In the screenshot it says the what the standby temps of extruder 0, 1 and 2 are. So you obviously you have them enabled in the software. Sorry, I meant replace an extruder stepper driver with the one from the X axis. The point being just to put one in there that works. Then you can also put the extruder stepper driver in the X axis and connect the X axis motor. Just to verify. Ah, but you havby TheTechnicalNoob - Reprappers
Re: Making a huge 3D Printer! - 10 years ago
I have no idea if anybody has tried this. But here's an idea: use square box stainless steel or aluminium extrusions and fill them with cement for rigidity. Bearings with delrin or machined teflon rollers could be used as guides if you use soft extrusion like aluminium. Heck, if you make it really big on the order of meters you could even use concrete reinforcing steel! That way it'd holds its sby TheTechnicalNoob - Reprappers
