I have found when I am using PLA I need to have my filament tension set lower than usual. Not sure if it is a freak kinda thing or what.by gmh39 - General
It looks fine from a printing point of view. Only trouble spots you might have are the holes and that circular part that comes out the front. Shouldnt be too bad. worse comes to worse you just print it with supports. As for orientation, you should be able to re-orient it in the 3D printer host program prior to slicing.by gmh39 - General
Quoteiquizzle Quotegmh39 Quotecakeslob I followed the Foldarap2 from the beginning of the project till the last Hbot revision where he went over to the rack and pinion.

So I am looking at spacing a motor for my first custom 3d printer design. I am using a CoreXY based system. Now I have a few questions: 1. If I get a high torque nema 17 and run it at low power without skipping steps, would that be quieter than running a mid torque motor at a higher power? 2. What dictates the noise made by a motor? I am looking to use these with A4988 drivers.by gmh39 - Stepper Motors, Servo Motors, DC Motors
You. Small steps. You can probably use the same kind of stepper for the z as the x and y. Its controlled by your electronics and firmware so as long as you have it calibrated correctly it should work fineby gmh39 - General

QuoteMeltManBob So are there any suggestions regarding a good plastic to replace linear bearings? I'm designing a corexy variant of the Mondrian using fishing line. It going to use adjustable, printable x and y carriages to help with slop created from wear. The carriages also run on aluminum extrusion. Check out the thread. I just in the beginning stages and still have to do some modeling aby gmh39 - General
So I came up with this layout for the CoreXY-Mondrian variant. black = extrusion/motor blue = printed part red = spectra line It integrates the motors into the corners, uses Spectra line instead of belts, and keeps the line inside of the aluminum extrusions. What do you guys think? See any problems?by gmh39 - FoldaRap
It is, but it is incredibly hard to print consistently. I ordered from Zen Tool works and although it works conductively, it always gets clogged in my nozzle (0.4mm E3D and 0.4mm Ubis) on my Printrbot Jr. BTW, I am also using it for a a stylus I am designing.by gmh39 - General
CURA can't really do thin walled objects. If your ABS is oozing out that much before your print you can either lower your temps or use a skirt to prime the nozzle before it starts on the actual object.by gmh39 - Printing
Quoteaduy someone should try making a drive that uses two flat rubber belts. the belts would run like a tread mill and the filament would be in between the two sets of belts. sorry for the crude drawing. you could use four timing pulleys and two small continous timing belts.

So I gave Cura a try. Im officially switching over. Runs much better for me and gives better prints. I've still got some tuning to do, but it was able to print a mold right out of the gate that repetier couldn't.by gmh39 - Printing
If you're in the US I can probably help you out. I got some Mondrian parts already printed out that I am just using for measurements.by gmh39 - FoldaRap
QuoteEmmanuel Yes, if you can use the CoreXY layout, it will avoid the biding problem with a simple H-layout (or for an H you'll need an expensive frame to make it work). I'de be curious to see your variation if you keep some parts of the Mondrian but manage to use a coreXY. I built an H bot also to understand how it works, and after that I realized why Ilan made his CoreXY like that It's takiby gmh39 - FoldaRap
Quotetjb1 QuoteHazer This debate is a nuance on perspective. From the perspective of any OTHER than the developer(s), the engineering of anything open-source is free. At least until they modify the design, which they then become classified developers. As Vegasloki said, a developer does invest into the design. If the developer is a company, the cost of the engineering of the design is rolledby gmh39 - General
QuoteOhmarinus Quotegmh39 Doesn't the 2 use linear rails and the 1.5 uses rods? I think thats what I said "There is a difference, that is that the 2.0 uses an extrusion as X-axis" extrusion with linear rails on it yeah. I was thinking just an aluminum extrusion with a printed part riding on it, not an actual linear rail.by gmh39 - General

Quoteerylon May be I posted in the wrong topic to gain wider interest? @vreihen:your point is interesting. Then why people managed to setup makerslide and v-slot ? They could have done the same result using available guidings. Is it because the price went down ? If so, with a new "delta profile" there would be even less parts so it should work : why nobody is then interested ? About making on oby gmh39 - Extruded Aluminum Frames
From my understanding (Im sure there are more knowledgeable people that can chime in) E-steps are for calibrating your extruder motor so that it will push the exact length of filament through your extruder that you tell it to. So you tell it to extrude 100 mm of filament, it extrudes 100m of filament (this is "new" filament, or filament still on the spool). I dont think e-steps would change wheby gmh39 - Printing

I believe it is either the Kossel or the Cerberus that use the extrusions for their linear motion. You can probably just use their vertical carriages instead of the ones with the 3DR to use the extrusions.by gmh39 - Delta Machines
Quotewhitemousegary Your problem is not about the gcode or the calibration, instead the hardware of your extruder. Be precise, your extruder is not quite extruding. The reason could be too much friction along the tubing, nozzle blockage, or having a poorly designed extruder. In case of too much friction along the tubing, it can be improved by using PTFE tube all the way to the tip of the nozzlby gmh39 - Printing
Depending what slicer you are using, there may be a setting for extra length after retraction. I know it is in Slic3r cause I had to use it the other day for the thin wall calibration cube I was printing.by gmh39 - Printing
