Quotethe_digital_dentist I bought the Gates belt from a distributor in the US and paid $2/foot, and had to buy the Gates enforced minimum of 50 feet. I have not noticed any change in print quality between the Chinese belts and the Gates belts. Sweet, I live in the us. Which one? I think it depends more on the printer. My printer definitely printed better with the pu steel core belt. But the belby warbunniex - General

Where do you get your gears? I'd love to make something like this but I have a terrible time sourcing gearing.by warbunniex - General
I would say keep with belts if you can. Lead screws are overkill for 3d printers and introduce inaccuracies in layer alignment. My build will be using one of these: Already ordered it. The 500mm one was 150 when shipping was included and it is very nicely built. Not sure where you can get cheap lead screws. You could look at ingus. But you really dont actually want a thicker screw.

QuoteM_Xeno I found that a strong Kevlar string coupled with an original Gates GT2 belt, with a minimal lenght, gives less ringing... The idler pulley may be a simple V-groove ball bearing, it's very reliable. Where did you get your Gates GT2 belt from? I've seen people talking about this and have not found a source.by warbunniex - Mechanics
If you want to use nema 23's you can use the bigfoot stepper driver or upgrade to a duet ethernet/wifi with active cooling. the duet can handle up to 3 amps i think(look it up before trusting me) if you blow a fan across the drivers. Stepperonline also sells nema motor breaks now for 50 ish dollars so you dont need to get a worm gear to account for power loss.by warbunniex - CoreXY Machines
I've used both and would have to say that file upload + ease of starting a print is the most important question. I've never had to wait more than a minute to upload via ethernet to the duet. However I've never found a fast way to upload to the smoothieboard. I would often have to wait 20-30 minutes to upload via usb or ethernet & the external sd card isnt really stable.

these guys have kevlar & polyurethane belts in 6 & 9 mm.by warbunniex - General
You're better off using 1 stepper motor and a belt & pulley system to drive the rest of the lead screws. If well assembled, they will never get out of sync. (which is a major pain to deal with). You also might want to consider using less. 4 lead screws is kinda unnecessary & can lead to more problems. You're better off with 2 on opposite ends of the bed. And even better than that is toby warbunniex - Mechanics
Well that's different. In most printers, gravity is taking care of backlash for the z axis. How does this design handle that issue?by warbunniex - General New Machines Topics

How is S-curve acceleration coming along with RRF? Marlin 2 is currently using it and I swear it prints a lot more smoothly than it did before. (smoothieware -> marlin 2)by warbunniex - General
I've been a delta speed racer for a while and only decided to switch over to corexy when I saw e3d's tool changing. I'm using their method of locating the tool with the ball & groove but I'm switching out the servo for an electromagnet. I prefer to have less moving parts. The current build volume is 300x300x500. I have currently modeled regular 12mm linear rails but I will probably be switchiby warbunniex - CoreXY Machines

Have you tried decreasing the extrusion multiplier? If enough pressure is built up in the nozzle coasting will not do much. Are you getting blobs were the filament is retracted? If you are not getting blobs then I would say your filament is either getting printed too hot or it is possibly wet. Have you tried a different roll of pla? while i like esuns selection, i have had a little bit of inconsiby warbunniex - Reprappers
You should go for some bigfoot drivers. youll be able to handle much higher current. though i would suggest a cooling fan for the drivers.by warbunniex - CoreXY Machines
the smoothieboard wiki still says that they do not really support external sd card usage. have you done anything to improve this issue?by warbunniex - General
Ya a drill press and a saw/ angle grinder is all that is really needed but plenty of people only have a printer for a tool (i have access to a great metal lab but i try to give suggestions that give wider options for people. this is reprap afterall)by warbunniex - CoreXY Machines
I like aluminum tubing but if ya didnt have access to a mill/ metal tools. I highly suggest printing it with carbon fiber pc. the stuff is damn stiff and has a high heat resistance. the carbon fiber reduces warping so you dont need crazy bed and heated chamber temps.by warbunniex - CoreXY Machines
Quotepamalofeev Sorry for my bad english.. I wanted to say that this is more correct, but not 100%. There is a position loop, a speed loop and a torque loop. Usually, a torque loop is not used, but a current loop with a sensor. These three loops are necessary for quality work. Thank you for the explanation. I'm not really much of a coder yet and there's plenty about motor control that I don't yeby warbunniex - Developers

Hey did you ever end up going for the trick laser arms? I'm curious about that option because it seems much lighter than the magnetic arms and the magnets are causing problems with the fan for my cold end.by warbunniex - Delta Machines

A forum for 3d printing isn't gonna be a great place to solve problems of social isolation or anxiety. Hell online is a terrible place to go. People are shitty online and you don't want our advice...

Quoteo_lampe How about an automated PID tuning algorhythm? I would love to have that. I don't exactly know how to start cause motor position is a bit different from temperature. But if there was a built in auto-pid tune built into the drive that would be awesome. like every time you started a print with a filament, the printer heated up, auto pid tuned the extruder, primed, and then printed.

O that seems like a much better way of doing pressure advance. Well outside of my abilities but i really like the idea.by warbunniex - Developers
You guys would probably have the best answer for this. I was reading about some filament measuring sensor the duet guys are working on and I realized if I'm doing a dc servo..then it basically has built in filament measuring if done right. That got me thinking.... We could stick with Bowden extruders and just move the encoder down to the end of the tube just above the hotend. That way you get tby warbunniex - Developers
