uArm Serial No.: D43639DAFC06
Firmware Version: 3.2.0
Operation System: Win(10)
uArm Controlling Method: COM port
I have written my own software to control the arm from a windows machine using the COM port, to do some special 3D printing jobs. When I opened up uArm Studio and saw there was a new firmware version (4.0+) available, I installed it. I read the popup about 3d functionality being removed, but I just hoped the G-code commands for the 3d printing were still available.
When I found out they weren’t available in the new firmware, I flashed it back to version 3.2.0 using uArm Studio. However, now if I try to heat the nozzle using G-code commands, it says ok, says it is supplying power to the heater (@127 when using M105 command), but doesn’t heat up and eventually throws a temp error.
I also tried to reflash the software using the .hex and the flash tool, but the issue persists.
Please tell me how to fix this, since I am currently unable to use the arm, and it worked before.
