If you want to know something about drivers in general, read the introduction about drivers in the main article here. A4988 … The most basic drivers from Allegro. The advantage of this driver is the price. The disadvantage of this driver is that it can only handle 1/16 microstepping and is therefore quite noisy. DRV8825 … These drivers are from TI.

3D printers use stepper motors. The name implies that the movement consists of individual steps. The most widely used motors use 200 steps, that is, 1 step = 1.8 degrees of rotation. If the printer moved in these large steps, it would tear, the print would not be so nice and it would also be very noisy because of the large vibration transmissions.

This board comes from a line of cheap Chinese 3D printer boards and is the successor to the SKR 1.1 board. The advantage of this board is a 32-bit microcontroller that handles more microstepping and many other advanced techniques that the 8-bit board can no longer handle.

Reason? Press pad ( heating bed ) for printers Ender-3 , but Ender PRO-3 is formed by a piece of aluminum plate, which when heated expands and bulges.

Hotend which has Ender-3 and Ender-3 PRO is not one of the best. This is mainly due to a small heatsink. Due to its size, strong cooling is required.

Of course, it is best to completely replace the print cooling fan with a larger one. The original fan does not do much and even if you put it on this adapter , for example, cooling will not help.

They are stronger springs (about 25 CZK) to replace those under the printing pad. Due to their harder “character” the printing pad sits on the trolley as stuck.

The sixth upgrade will theoretically be the one you are all waiting for, a new motherboard with other stepper motor drivers ( drivers ). Here again it is more complicated. The new album should give you something more than the original one. Honestly, everybody will offer you today.

It will help quiet your printer, eliminate some problems and make your life easier. A little bit, but better than nothing. What is it about? HOTEND ! Yes! Finally hotend!

In addition, it facilitates the printing of elastic materials. Maybe some have recognized that there is talk of a direct extruder. The cheapest is to print your engine mount and do it yourself. Which is probably the best solution.

This is the second Z axis. Why is it important? For simplicity, imagine moving the entire weight of the direct extruder / hotend to the right-hand side of the X axis.

As already mentioned, glass helps to create a flat surface for printing. If you use a different surface, your printing area may not be perfectly flat.

There are many types of printing pads. Glass, Mirror, Ultrabase, but the Holy Grail is considered printing on PEI on a flexible steel plate with a magnetic pad. Advantages:

Currently, the two most common are: BL TOUCH and an induction probe. Today we will show how to connect an induction probe on the example of the Ender 3 printer, with motherboards from the MKS and SKR families.
