The following descriptions and descriptions of the parameters of the different drive modules are limited to the
version produced by the makebase. Different manufacturers may have different
Drive subdivision table: (Motherboard subdivision jumper resistance from left to right are M1, M2, M3, respectively,
where the resistance is High, the resistance is removed to Low, the motherboard defaults M1, M2, M3, are high,
there are other requirements , can adjust itself).

TMC2208 driver chip internally uses a differential algorithm to extend the 16 subdivisions to 256 subdivisions. The
step values are calculated according to 16 subdivisions.
It is recommended to use 16 subdivisions with a good mute effect. It can also be adjusted according to the
subdivision table according to its own needs.
TMC2100 drive has a clear mute effect and the motor track runs more smoothly. The internal algorithm optimizes
the setting, and the drive subdivision defaults to 16, which is not affected by the transformation of the external
jumper resistance.

The driving current must be converted by measuring the driving voltage. To measure the driving voltage Vref, refer
to the following figure.
The Vref can be adjusted according to the running condition of the motor, and the upper knob can be adjusted by
adjusting (clockwise to increase, counterclockwise to decrease).
Note: Before the adjustment knob, it must be done in the case of power failure. After the adjustment is completed,
the power-on measurement is taken to prevent the drive from burning out.
Formula
I=Vref/0.8
I=Vref*2
I=Vref*2
I=Vref/1.414
I=Vref*1.9/2.5

Ⅴ.Firmware Upgrade Instructions
The factory firmware is up to date, so no updates are required.
5.1 The ways to get the MKS Robin Nano Latest Firmware.
Get firmware from customer service or technician
Download the firmware from the makerbase discussion group.
Download on Web:
https://github.com/makerbase-mks?tab=repositories
5.2 The methods for updating the firmware
a. Copy the latest upgrade to the SD card root directory, including:
1
Mks_font
2
Mks_pic
3
Robin_nano.bin
4
Robin_nano_cfg.txt
5
Mkswifi.bin
Attention:Do not modify file names. No need to copy mkswifi.bin without WiFi module
b. Plug the SD card into the motherboard and power on,hear drops ~ ~ A short sound, touch screen display update
process, and so about 30S after the completion of the update.
c. You can click” Settings--about” on the touch screen , to view current firmware information.

12
Ⅵ. USB driver Installation
MKS Robin nano uses CH340 drive. You can get USB driver file with customer service or technician.Click to install the
USB driver file, after the driver installation completes, will connect the Robin motherboard the USB to insert the USB

Ⅶ. Machine parameters and function configuration
7.1 Basic settings （ Important, must be set ）
Note: The thermal end interface on the motherboard should be connected to the thermal, otherwise an "error"
prompt will appear.

7.2 Function setting

A. Motor direction: After the point back 0, if the direction of the reverse direction, then modify 1 or 0;
B. Pulse value ： The pulse value of 1mm for each axis is calculated, and the formula for calculating the pulse value of
each shaft motor is as follows:
Formula of pulse number/mm of synchronous wheel motor: （ 360÷step angle ） ×Subdivision÷ （ Diameter×3.14 ）
The formula of the pulse number/mm of The screw rod Motor: （ 360÷step angle ） ×Subdivision÷lead
C. endstops type: The endstop switch is divided into two types: normally open and normally closed, 1 is normally
open and 0 is normally closed;
D. Enable the endstop of each axis: the endstop switch triggered when returning to zero, generally XYZ is the
minimum limit, and delta is the maximum limit;
E. Enable the software limit of each axis: the maximum travel set in the configuration file, the maximum travel
cannot be exceeded when moving.
F. Homing direction: Set according to where the machine's endstop switch is installed on the machine. For example,
the endstop switch of the x-axis is placed on the left side of the x-axis, then the homing direction is the minimum
value returning to zero.
7.3 Delta Settings
The parameter corresponding to the serial number in the picture
(1). >DELTA_PRINTABLE_RADIUS
(2).>DELTA_DIAGONAL_ROD
(3).>DELTA_EFFECTOR_OFFSET
(4).>DELTA_CARRIAGE_OFFSET
