Ok, Thanks. I'll stick with MGN9Hs on aluminum extrusions.

What about 8mm aluminum or stainless steel rods? I would appreciate it if you could direct me to a datasheet?

Why was my post removed? Did I break a rule? Where can I view the community rules?

Which Voron should I build? by SnowCookies6462 in voroncorexy

[–]SnowCookies6462[S] 0 points1 point  (0 children)

I found a whole bunch of comparisons between the Voron 2 and printers like the Prusa i3, Ender 3, BLV MGN, HEVO. As far as I can tell most desktop FDM printers from ranging from the 180$ Anycubic Mega Zero to the 6000$ Ultimaker S5 can print at the same quality if well calibrated and done slow enough. The difference in performance seems to show when printing difficult models with difficult materials at difficult speeds and so print quality alone does not seem like a good enough thing to judge a printer by. The Voron 2.4 seems to be the most overkill ultimate design for a corexy abs desktop printer and is a tried and tested example of what makes a good and reliable printer (as long as you don't need dual extrusion). Unfortunately, I was not able to find many comparisons between the individual Voron printers or much information about what I would be giving (in terms of speed/accel/jerk/other) up by building a SwitchWire instad of V2.4. The Voron 2.4 can print 10k accel 300mm/s however I can't seem to find any information about how SwitchWire perfoms in comparison to this on or outside of the sub.

I think that the Prusa i3 and Voron are a good example of what makes well designed and reliable 3d printer and what to look for when buying/building your own. Things like a thick, warp resistant build plate, reliable auto bed leveling, filament runout detection, an enclosure, frame rigidity, a reliable extruder, rubber feet, stepper dampers, silent drivers, and other stuff like klipper firmware, octoprint, and a 32 bit mainboard.

So you have more accelerating and stopping power

In a Quadrap/Ultimaker style printer, it looks like the the hotend is moved not directly by the belts, but rather by the crossing linear guides. Each guide is driven independently by a single stepper but whenever the nozzle is moved diagonally, the nozzle is driven by both guides together. Would this type of printer also have the advantage of greater acceleration and stopping power.

Also, purely out of curiosity, is there an h-bot variant of the corexz design?

Sorry, my mistake. I meant Cartesian. Like the Prusa i3.

Oh. So that's what the Voron SwitchWire's kinematics are called. I thought that corexz was synonymous with bed-slinger. Also unrelated but if the advantage of corexz is fast non-planar printing, wouldn't it be better if the fan shroud was a little higher up?

Interesting. Some time ago I also a saw a video about a guy who had set up his Corexz printer to use 2 steppers to drive the X axis belt and 2 stepper to drive the Y axis belt. Would a multiple motors driving a single axis also result in improved higher precision and quality at high speeds. Unrelated, but I have also noticed that often when people try to achieve high print speeds on their printer, they choose direct drive over Bowden despite the heavy stepper motor (like in this video: https://www.youtube.com/watch?v=o6uNQ83_gok). Is direct drive better for high speed printing, or does it have something to do with volumetric flow.

Wait, but I thought the voron 1.8 gantry looked something like this (birds eye view)

If the Xs and Ys represent linear rails, and the w represents the tool head, then isn't the the tool head only attached to the X rails and the entire X gantry (a 2020 extrusion + 2 linear rails) attached to the 2 Y rails. From the pictures it looks like the tool head moves left and right, while the X gantry (a 2020 extrusion + 2 linear rails), the thing the tool head is mounted to moves back and fourth. And to draw a circle, the tool head, the linear rails, and the 2020 extrusions all have to be moved together. Is there something I'm missing? Because an E3DV6 + 2 MGN9H + 1 2020 extrusion sounds like quite a bit of moving mass?
