This method only applied to users who can NOT level DexArm with Rotrics Studio or Touchscreen. If you've done the level procedure, please skip this section.

A. Open Rotrics Studio and click Terminal, send commandM891 X0 Y0to reset the slope value. Then reboot DexArm.

B. Place a piece of A4 paper between the print plate and the nozzle.

C. Adjust Z-axis for 4 points:

a) Point A

Open Rotrics Studio and click "Terminal", send commands "G0 X0 Y350 Z0" to move the arm to Point A, switch to "Basic" panel, and adjust module height with "Z-" button, keep adjusting until there is slight resistance on the A4 paper from the nozzle.

Send commandM114to read and record down the current Z-axis value. We will refer to this value as "ZA".

b) Point B

Open Rotrics Studio and click "Terminal", send commands "G0 X0 Y250 Z0" to move the arm to Point B, switch to "Basic" panel, and adjust module height with "Z-" button, keep adjusting until there is slight resistance on the A4 paper from the nozzle.

Send commandM114 to read and record down this Z-axis value. We will refer to this value as "ZB".

b) Point C

Open Rotrics Studio and click "Terminal", send commands "G0 X50 Y300 Z0" to move the arm to Point C, switch to "Basic" panel, and adjust module height with "Z-" button, keep adjusting until there is slight resistance on the A4 paper from the nozzle.

Send commandM114 to read and record down this Z-axis value. We will refer to this value as "ZC".

b) Point D

Open Rotrics Studio and click "Terminal", send commands "G0 X-50 Y300 Z0" to move the arm to Point C, switch to "Basic" panel, and adjust module height with "Z-" button, keep adjusting until there is slight resistance on the A4 paper from the nozzle.

Send commandM114 to read and record down this Z-axis value. We will refer to this value as "ZD".

D. Configure and set the slope value

Please calculate according to the following formula, keep the negative sign of Z-axis value.

Then open "Terminal", and set slope values with command M891 XSlope YSlope, for example: M891 X0.02 Y0.02.

Reboot the Arm and the manual leveling is completed.

Slope value of Yaxis=(ZA−ZB)/100Y axis=(ZA-ZB )/100Yaxis=(ZA−ZB)/100

Slope value of Xaxis=(ZC−ZD)/100X axis=(ZC-ZD )/100Xaxis=(ZC−ZD)/100
