looking for a good 3d printer

[Zeeflyboy]

Ive been looking for the Pi but cant find many options, Any specific ones you know of?


if i make the machine then the motors will be nema 23-24s, might have to go for separate drives any way.

I like the look of the Duet as its all in one but could be an issue if a section stops working. At least separates can be replaced

I use a raspberry pi with the official 7" touchscreen and octoprint as my printer's control interface. Very neat solution - also allows a webcam feed and remote access.

astroprint is another good print server, I think they are adding easier touchscreen support. Less technical than octoprint but looks easy to use and well presented.

Nema 23's for a 3d printer unless it's crazy over sized is probably too much like you don't want to use nema 34's on smaller routers

Yes, sorry I meant to say for the z-axis, I have a pair of complete slide/lead screw assemblies. the x,y will be belt driven so plenty fast enough.

Is the PI just running the printers driver or does it control the steppers and heating mosfets direct?

guessing i will still need a duet or RAMPs with the PI

In my setup it's just acting as the computer that interfaces with the ramps board through USB.

I use a similar setup on my Hictop 3DP-12 (Prusa clone with aluminium extrusion frame) - it has a great benefit of being able to run the Pi with Octoprint remotely across my LAN and I use a Pi camera, which is integrated to keep an eye on the print whilst its doing it. So that's PC in office with web browser interface---->Pi with Octoprint---->Ramps based control board from Hictop running Marlin firmware----->3DPrinter.

I've just finished upgrading the printer this weekend with a filament sensor, although I struggled with using the firmware's M600 filament change routine, which kept timing out Octoprint, so rolled my own GCode to emulate it without the timeout issues.

are you using the standard Ramps or the 32 bit Radds board?

have you got any wiring diagrams for that set up?

Not as such - as with Zeeflyboy the Pi is connected to the Ramps board via a short USB cable and the Ramp board uses 4 wire stepper wiring, which is likely the same as you would use for a CNC router.

The board is shown here (scroll down a bit for the schematic): https://www.hic3dprinter.com/collect...e-mother-board

I mounted my Pi onto the printer by using a 3D printed case (shameless channel plug) and I have my property flood wired for CAT5e so it just becomes another device on it accessible from any PC/tablet etc. with a browser:

Wow, i would never do that My printer prints non stop and why i would need to spend time watching its whats its doing, as if all is setup right it works flawlessly. last time i had a crash was when filament went from 1.75 to 2.5 at almost end of bobin...
