ANYCUBIC Kobra Max 3D Printer, Large Auto Leveling

He probado con piezas que duran hasta más de 24 horas imprimiendose y la calidad es muy aceptable. La base se calienta así que las piezas son muy fácil de retirar con una espátula y no deja residuos. No se ha cortado el hilo de impresión aunque eso no depende de la impresora sino de la calidad del plástico.

It prints quite well, and was up and running in under 10 minutes. There are no bed leveling screws, but so long as you make sure the gantry is leveled AND squared, this isn’t a problem.
ABL is done via pressing the nozzle itself against the bed to detect strain across a 25 point grid.
Heating is plenty fast, and the unit comes with a PEI-on-glass bed. For an extra 35 dollars, you can get the flex plate (which i suggest).
Cons: does not handle z-hop commands well. This results in pills all over the side of the print, and it WILL cause an aligned z seam to swell up and ruin your print.
E-steps are usually off on the extruder alone. Typically, it is 6mm short.
The filament runout sensor is on a flimsy mount, and not only flexes during retracions, but will squeak with fast retraction settings. Some oil solves the squeak for a moment, but it would benefit the sensor if it had a teflon coating, this would help.
You have to heat the unit to 220c minimum in order to auto feed or remove filament, and that cannot be changed. Why?
No manual leveling options. If the nozzle is dragging on one side, you may likely need to force the gantry to max Z height in order to level out the Z screws.

Pros: decent cooling, great temperature control, and easy setup in pronterface.
Stepper drivers are digitally programmed, and you can check settings with m500
Offers PLA and ABS preheating options.
Rapidly heats up to print temp and doesnt vary much at all, even with full cooling.
Rock solid.
Capable of printing at 120mm/s with accuracy of +/- 0.45mm in x and y using stock parts.
Super quiet. Unless you’re speed printing, it’s silent.

Notes:
Advised jerk is 8-15mm/s. 10 is what mine is set for in all respects.
Max moving acceleration should be 5000 or less
Max acceleration on any other setting shouldnt exceed 3700, as it has no appreciable benefit above this, but the suggested acceleration is 800 to 2000 for most prints.
225c at 15mm/s is perfect for the first bridging layer.
Tends to do a small deceleration across exact center in the bed. I dont know why, but it does this for anything printed within 25mm of the center. It isnt a problem, but can produce noticeable effects on the print along outer walls when going at 80mm/s or higher.
Do not insert the SD card into the touch screen. This port is for bios upgrades only.

Overall, totally worth the price, and a blast to operate. You wont be disappointed.

The Kobra Max is one of the largest 3D printers you will find for under $1000 currently, and it freakin rules!

Most 3D printers need to be leveled using “the paper method”, of which you’ll find lots of videos about on youtube. But I’ve never once had to do that with this printer, because this 3D printer has a more high tech way of auto leveling than your average printer.

Instead of adjusting knobs manually at the bottom or on the computer screen, the computer auto levels by pressing down on multiple points on the board and fixing all the kinks by itself in the computer.

If you don’t know what auto leveling is, look it up on youtube with other printers, imagine all the suffering you’ll have to go through, really try to visualize it, and then realize this printer will cause you no such grief, and take a big sigh of relief.

Of the few problems I’ve ever had with this printer, auto leveling has never been one of them. I actually haven’t had to level it in quite some time.

The quality of the prints is also really quite good. Once you’ve got all the settings on your slicer set up properly on it, the thing’ll knock out practically anything you throw at it.

I wouldn’t say it’s “silent”, but it’s pretty dang close. I’m the kinda guy that will take the batteries out of a clock because the ticking annoys me when I’m trying to sleeping, but the humming of this printer on the outside of my door isn’t bad. It’s quiet, and has a good low frequency instead of high.

When I was having trouble at the beginning (being my first 3d printer), I emailed the company, and they always got back to me pretty fast, and helped solve the issues I was having. They were very very helpful.

If you are a complete beginner, but you want a LARGE printer, this is a very good printer, and I would highly recommend it.

It takes up a ton of space (obviously), but the printer just works. The engineers that designed this really put in the extra work to make a good product. Five stars all around.
