uArm communication errors, not respecting movements

uArm Serial No.: (the No. at the bottom of each uArm reading “UARM-0725160146”)

Firmware Version: 2.2.1

Operation System: Mac

uArm Controlling Method: Python - pyuarm 2.2.5.3

Hi, I wrote you two months ago and I’ve realised that you replied in the same way to all the people having the problem, but it still not fixed. So my uarm is behaving strangely, does not respect the coded movement. It used to work until end of January, than it started to have problems.

I am having the following communication errors:

pyuarm - ERROR - Communication| ERROR: send b'#511 G0 X137 Y173 Z100 F5\n', received error from robot: $510 OK V2.2.1

pyuarm - ERROR - Communication| ERROR: send b'#513 G0 X137 Y173 Z83 F5\n', received error from robot: $512 OK V2.2.1

pyuarm - ERROR - Communication| ERROR: send b'#515 G0 X107.36 Y193.64 Z83 F5\n', received error from robot: $514 OK V2.2.1

pyuarm - ERROR - Communication| ERROR: send b'#517 G0 X107.36 Y193.64 Z100 F5\n', received error from robot: $516 OK V2.2.1

Please let me know as soon as possible. I’ve tried to uninstall and reinstall new versions of pyaurm, from master branch, same issue again. I don’t have anymore time to waste.

The new library has already been uploaded at the beginning of March.

Sorry for not making an announcement.

I’ve already re-installed it using dev branch. Now I got this error:

pyuarm - ERROR - UArmConnectException - set_position - 'uArm is not connected-'

However, the uArm is connected and I can control il from uClient. If a make a simple program like this I get the error.

import pyuarm

uarm = pyuarm.get_uarm()

uarm.set_position(100,100,150, 5)
