So my guess would be
SM = stepper motor
57 = width of motor
T = most likely "Torque"
56 = length of motor
280 = 2.8 a
4 = 4 wires
A = 1.8 pitch single axis

You can also refer to this pdf for future motor references.

Thank you so much for your reply and for your help!!!
However, your decision to use the old Creatr only for spare parts in order to upgrade your TronXY x5sa Pro, makes me feel that I'm trying something that is not worth at all. Anyway I also have and another 3d Printer the Ender 3 Pro and in case that Creatr's upgrade fails I'll upgrade my Ender 3 according this tutorial "Ender 3 Pro and Duet Maestro Guide "

That 2.2A setup will be for all the motors? or I can make it only for the Z-motor and for the other X, Y i can use a different curent setup?

You can individually set the motor current for each driver that a motor is connected to (e.g. your Z-axis stepper would be 2.2A while your X stepper and two Y axis steppers would be some other value).

This is Amazing! I think that the Duet board will change completely my old Creatr!

@T3P3Tony said in Creatr Leapfrog – Converted to DuetWifi:

So if the motor is rated to 2.8A then you can use a Duet 2 set to 2.2A

Thank you @T3P3Tony , That 2.2A setup will be for all the motors? or I can make it only for the Z-motor and for the other X, Y i can use a different curent setup?

Some other parts of the printer that I’m going to keep before the restoration are:

1. The powersuply, that is a : S-400-24 24V POWER SUPLY
2. The bed that is the : Heated Print Bed (Leapfrog HS) ( thermo glass bed with dimensions 34.6cm X 45cm and powered with 24V
3. The Z-probe : A JIMOU sensor 10-30V DC 150 mA https://bit.ly/32yzCS8
   

Last but not least I have to mention that Creatr is a Cartesian 3D printer in which the print bed moves only in the Z-axis using one stepper motor, X-axis and Y-axis are moving independently . X-axis uses one stepper motor and Y-axis uses two stepper motors. The extrusion system is direct with extruder and extrusion motor moving together.

To get an idea about how fast an Arduino can deal the different measurements from a laser sensor, you can see this video: Measure Distance with VL53L0X 6 pin Laser module with Arduino
Although the VL53L0X sensor is very accurate and
(in my opinion the best laser sensor for a 3d printer due to its extremely tiny size) Arduino can't manipulate the measurements fast enough. (you can see the rate that the measurements appeared on the screen). However, I think that the VL53L0X sensor definitely could be used for that purpose maybe with another microcontroller ...

@gianakop

Let’s see what kind of electronics I have to deal with DUET Wi-Fi board....

The motors:
The printer has 5 stepper motors:
X-axis: (1pcs) Smart Automation PN.SM42HT47-1684A
Y-axis 2pcs) Smart Automation PN.SM42HT47-1684A
E-extruder: (1pcs) Smart Automation PN.SM42HT47-1684A
All these 4 motors are the same: SM42HT47-1684 nema 17 bipolar stepping motor 1.68A 4 leads 5kg.cm holding torque)
And here is the motor and the datasheet:

The Z-axis motor, is a much bigger stepper motor:
Z-axis: (1pcs) Smart Automation PN.SM57T56-2804A-6mm

I haven’t the datasheet for that motor, but I think that is very similar to this motor :

According to the DUET guideline for the motorsI think that I can drive the X, Y and E motors directly with DUET Wi-fi board, but I’m not sure for the Z-motor.

The options that I have to drive the motors are:

1. Drive them directly from the Duet wifi board (I’m not sure if I can do that with the Z-motor because it seems that it has 2.8 A current)
2. Use the Duet Expansion Breakout Board (I don’t know where to find it)
3. Use the Stepper Motor Driver TB6600 (cheap from e-bay)
4. Or keep the old external drivers (Microstep Driver CW230)
   
   I would appreciate any suggestion …..

Creatr Leapfrog – Converted to DuetWifi

Hi All,
I‘m Nikos from Greece and in this thread, I’ll try to convert an old Creatr Leapfrog 3d Printer to a super printing machine using DUET electronics.
This printer was the very first Creatr model, with a single extruder and an Arduino Controller Board Ramp connected with 4 external Microstep Driver CW230 motor drivers.

I want to keep only the chassis (with very little changes), the motors, and the power supply, and I’ll change all the cables, the electronics parts, and the extruder. (Some of the old electronics are burned and the printer was out of functions for many years)
This will be a long time project because I don’t have all the necessary parts that I need.
Any suggestion and advice is welcome. The board I’m going to use is the Duet 2 Wifi in conjunction wit a PanelDue v2 with a 7" screen
Here is the situation of the printer now:

The existing electronic part is also a mess:

Please Keep tunned to see the progress of this project and help in order to create a guide for all the other people like me that have an old Creatr Leapfrog
