When using the robot software on 7 Jun (using this version of the code), the 1DoF platform appeared to drift upwards 2-3 cm during operation (the actual motion trace had only 4-5 mm motion magnitude). Previously this occurred when there was an issue with the cable connections, or due to a bug in the code (now remedied). Could be a different bug in the software causing this - but, will require more testing as there could be a number of things causing this (e.g. not pressing home between traces). We also noticed this issue on the same day of operation.
