This improves the accuracy of homing and mesh compensation and allows for unlimited layer height selection.

Ender 3 v2 hemera full#

I've switched to a 2mm pitch single start lead screw which improves the full step resolution from 0.04 to 0.01 without changing the motor. The one thing that I would change about the Ender 3 Z axis is the lead screw. If there is any droop it would be compensated for by leveling the bed or using mesh compensation (which you should use because the Ender 3 bed is probably warped.)

The Z axis of the Ender 3 isn't that bad either provided the wheels have been properly tensioned. Switching to 0.9 degree on the X and Y won't likely show any improvement. The steppers aren't amazing, but they aren't bad. The design as it is is actually quite good. I just don't think there will be much improvement. Personally I wouldn't put too much effort into altering the Ender 3 in such dramatic ways. There's no issue with using this and mesh levelling at the same time though I generally advise to get your machine as mechanically level as possible, then you may not even need to use mesh compensation, other than to check the bed is flat occasionally. I just wrote a separate macro to level the gantry when I feel like it needs it, see. It's quite simple to set up in config.g, and the homing macros don't need to change. I like the gantry levelling (I use one of dc42's IR probes), which means that the X axis stays level and doesn't bind on the Z (as it would if it got a long way out of whack). With the Duet's (or rather the Trinamic driver's) interpolation, I can't say I've noticed it on my Cartesian machine with 1.8º motors. There should be a small increase in quality, though the infamous Vertical Banding is seen more on CoreXY machines. If you don't intend to go that fast, then, as I do, just pick a NEMA 17 motor out of your parts bin!Īs the Ender 3 is a Cartesian printer, whether you choose 1.8º or 0.9º steppers is a bit trickier. You can do the calculations if you want see However, if you want to go really fast (eg 200mm/s or faster), you're going to need low inductance motors, and 24V power supply.

Generally, this is my view too! Certainly, when all there was was 1.8º motors, slow printers and stepper drivers capped at about 1.2A, I don't think there was much talk of inductance. TL/DR: Both are fine! Or try the original motors first.

I like tinkering but i might not be very good at it If you want to i can update you on my progress I hope you guys can give me some insight. It seems like this could reduce the z-movement during a layer with an unleveled bed, but is that even noticable?

When using mesh bed levelling, is there a benefit to not wiring the two steppers in series? (connecting one of them to the spare extruder driver and using software to level the gantry) Secondly the Dual Z idea seems a little challenging:

0.9 is better than 1.8 and longer motors are stronger! The DuetWifi can drive any Nema17, so you are fine with most of the stuff you find online'Ī little insight or someone more qualified than me saying 'both are fine' would be a massive help for me Stepper motors are confusing enough and reading the wiki and comparing the motors made it kind of worse I always assumed 'they just work. My main question is: Would the E3D High torque axis motors be a good choice? On paper they seem to be better than the 17HM19-2004S ones recommended by dc42, plus they are all black and have plugs instead of wires coming out of them. Possibly with some cheap Dual Z-Axis kit and two stepper motors for ZĤ)Hiwin-Rails for Y und X (If i feel like spending another 200 bucks.) I want to keep by BLTouch - should work fine Currently I'm planning on upgrading to this:

Since Christmas is coming I wanted to treat myself to some Upgrades to my Ender and need some advice on a couple of parts. I've had a duet wifi on my Tevo Little Monster for about 6 months now, and although the print quality is not outstanding due to several mechanical problems, I've never really gone back to using my Ender 3 with it's MKS board and Octoprint ( The Duet board is just so much nicer to work with).
