@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?

config.g attached below

@t3p3tony thank you for the help thus far.
I will get the homing files tomorrow when back at the workshop.

I will also check the thermistor resistance tomorrow.

Thank you

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

Paneldue 7i there is an error of "Warning: failed to parse response k{ in state 12

What is this error/ how to correct?

@t3p3tony X axis moves and homes (double tap) as it should, y axis does not move (integrated stepper driver needs to be re configured/awaiting on cable however x axis moves as requested when connected to y axis driver and manually touch y end stop to trigger). Bltouch probe can be deployed and retracted via g code but when z home or home all are requested, the endstop error occurs. Have changed the thermistor values and they change 1 degree. Re run the thermistor calibration cycle and still no change.

@t3p3tony Have refreshed the config.g and made some small changes, Below is the config.g files and the M122 readouts from all boards. No longer getting Error:Invalid remote handle". In console of the Paneldue 7i there is an error of "Warning: failed to parse response k{ in state 12, not sure what this means/refers to.
When homing z (bl touch) there is an error of "failed to enable endstops". Is there something to be changed in the homing files to suit the 1xd boards/bltouch also the 1xd boards in general?
Have tried the thermistors on "temp out 1" for both boards and both still read in the 69 - 70 degree range. have triple checked the values again the configurator and slice engineering website.
Z axis is a nema 23 connected to a mks tb6600 and then to 1xd board.

; Custom settings are not defined

the thermistor settings are as per the rep rap config tool for slice engineering 300c hotends

thank you

@t3p3tony have tried a fresh sd card, re flash of firmwares to the main boards, checked communications before and after changing the board addresses and all communications work as expected.
The errors for the invalid remote handle still show on initial startup on the panel due and upon diagnostic request boththe duet 3 and toolboards show reset errors from power up.

Have changed the thermistors as per the slice engineering tables and the temp readings only change1 degree.

@phaedrux yes, got mixed up somewhere along the lines and a second post was created.

Having a few issues which im not even sure where to start at this point. In a nutshell,
have the duet 3, tool distribution board, 2 tool boards, 3 1xd boards.
Both the duet 3 and 2 tool boards have remote handle errors and im not sure where to start.
The thermistors for the hotends both read 83 degrees or -83 after reboot sometimes reading as high as 2000.
running jss57P2N motors on x and y and a nema 23 via a mks tb6600 on z.
Bl touch v3.1 attached to tool board/extruder 1.
Have tried a new sd card, all firmware for both duet 3 and expansion boards are all 3.3 stable, still getting a "remote handle" error.
