@robert this is the same bed setup as taz pro so the issue is present on both machines. There is a lump in the silicon patch where the heater wires go in and this is where the thermistor wires can get smashed. If you route the thermistor wires around the side of the lump you should be able to tighten everything down without it smashing the thermistor wires

@tutley Unfortunately theres too many beds with inconsistent thermistor wire lengths. I tried this already and its not possible on some machines cause wires are too short. But we can try on ones that have longer wires.

@tutley So I tried it just now and its pretty difficult any way because if you route the wires on the idler side of the hump, you run into the wiper mount, and if you route them on the motor side of the hump the run into the cable cover. Plus its just difficult in general to keep those wires on the side of the hump when laying the bed down.

@tutley Its not impossible to route them around the hump on the idler side, just very difficult.

Right now we're looking at raising the bed surface 1.11mm to make room for those wires. This will require changing bed spacers to these: https://www.mcmaster.com/92320a763 and modifying the flexy corners.
This would accomplish similar to what was proposed in T9909 so the plan is to test on Mini 2 also. There is a little of the bed mount fasteners sticking out the bottom of the bed plate so hopefully no new hardware will be needed there.

@logan Will this require any change to start gcode?

Is this going to change bed sagging/bulging? Do we need to modify the printed standoff in the center with these other changes?

@karrad we will find out during testing, wont affect the wipe at all so I cant think of any reason it would off the top of my head

@adam probably will need to add the same amount of thickness to that center standoff

@logan Awesome, I am not sure how we would have identified users in the field easily for inclusion into Cura if that was required.

@logan can you put in a PR for the new bed spacers in whatever quantity we need to test this?

@adam @logan @karrad i believe we will need to adjust the flexy corners as well as the center standoff all by 1.11mm

@adam i ordered these 11.11mm spacers back when we were developing the modular bed system. i sent 20x pieces with @Heather to give to @logan. I have another 20pcs here for further testing in R&D

These adjust the bed corner and standoff by 1.11mm

i have installed these on my quiver and if install the bed so the thermistor wires come straight out the side, you can shine a light from the backside of the bed to the front and you can see the light under the wires, so the wires are not being compressed at all and have a bit of a gap.
These parts combined with the 7/16 spacers should alleviate any issues here. This should give a more consistent first layer as well.
I am printing another set to install on my mini 2 and this should alleviate T9909

Sounds great! I will get some prints of those corners going over here so we can continue testing

I measured some of the bed heaters we have in production to get a range of thicknesses for them.
