Good Evening Ian,
Didnt get the chance to revert back to 3.3 due to time constraints,and also a bit hesitant at this point due to when 3.3 firmware was installed there were issues with homing (as stated above, changing homing scripts did nothing), running a bed mesh would stop and error after probing 5 points (was unable to resolve this issue) so the bed was manually leveled and checked every few print runs.

Did not get the chance to switch the 1XD boards around (time constraints).

The new Y axis motor is exactly the same as the original "stock" creatbot motor and all dip switches and tuning parameters were copied over and besides the aforementioned issues, everything worked fine.

As stated above, the machine had not been switched on or run since the last time when the circles issue was raised here in the forum. This time round, the only change was that the rpi4 has run an update and the gcode file that was used last time and saved on the sd card was run after the update to which not only did the print come out differently (the offset/skew is better/tighter) but the machine itself i.e the motors especially sounded as if they were heavily labouring, very jerky/deep vibration sort of sound on all movements. And this is where the testing ceased as the only thing that changed was the rpi4 updating and thus raised more questions of why is the circles "skew" now better than previous but still skewed none the less.

Cheers,

Albert

@mfs12 thank you, first time i had seen it come up and wasnt sure what it was.
Cheers

@t3p3tony Im back again, Apologies for the delay,had some other things pop up and this took a side step.

So back onto the setup of all this today and have a few new issues. X,Y, Z axis all move and home, happy days. Extruders both work. However, the hotends overshoot =/- 10 degrees, fluctuate a few times and then sit 5 degrees above target temp. PID tune has been run three times and the problem persists. Not sure what to do here.
Until today, the heat bed and chamber heater (both 240v ac controlled via ssr) were not connected as this was the last step of the process. The heated bed was connected to "out 0" with power jumped from power in - out0 power in. The red led next to the out 0 connectors was illuminated as soon as the power was switched on and subsequently the ssr was then activated. Power down, disconnect the ssr. Power up, multimeter shows 23.9 volts coming from out 0. Commented out the bed heater in config.g to disable it and check if it was maybe a typo causing this. Nope. Removed the sd card, unplugged everything from the board, power up and still have the red illuminated. Checked with multimeter and there was 23.9v coming from the terminal. Bad mosfet?
Have a second board that is still in the box, pulled this out and bench tested it (no sd card, no connections other than 24v in with wire across from power in to out 0 power in), dont really know what the caper is, red led illuminated thus second bad mosfet on a brand new board. Back to config.g to switch the heated bed ssr output to out 7. re terminate wires and works as expected. Bit frustrated though with 2 boards having bad mosfets.

onto my next query, 2 toolboard 1lc running bondtech lgx extuder with slice engineering hotends, 50w heater and 300 degree thermistors. As outlined above, hotends are over shooting initially and staying above the target temp. The hotend cooling fans are setup to be thermo controlled, however this isnt the case, they are either on from startup regardless or dont switch on at all. a virtual temperature sensor was also created for the mcu to control a fan in the elctronics area to keep the boards cool, set at 40, this fan stays permanently on. Again, maybe a type or misread in the config.g?
