Definitely interested to see your results. Boss is wanting to order a second machine for redundancy soon. Perhaps I can convince him to invest in a couple of rails if your results are good.

Had an extra long warm up of 90-120 min the other day and required very little adjustment compared to normal 45-60min soak. We are still using the original aluminum extrusion.

From what I have read in this server, Funssor is a gamble.

IDEX XY Offset drift (VC4)
Doesn’t sound like a motor holding force issue, otherwise we would be losing steps and seeing it everywhere.

IDEX XY Offset drift (VC4)
I think mine maxed at 100mm high, but it just barely fits diagonally on the 500mm bed. I see very slight issue on the outer edges, but fortunately it is hidden after it is installed. Even if it wasn’t you have to really know what you are looking at to see the very slight misalignment. Talking not even a layer width.

I greatly appreciate all the work everyone has put into researching these obscure issues as it helps others perfect their machine and helps further refine the next iteration of the design.

IDEX XY Offset drift (VC4)
I am here mostly for the troubleshooting and belt tensioner guidance. T1 prints about 5g of support interface material for the 750g of material printed by T0. End user will likely never see anything wrong.

I wouldn’t say this has been detrimental, as I watch the first layer anyways. No point in trying to save 23min of labor just to lose a 24hr print and 750g of filament.

Sounds about what I was seeing too using a 0.6 and 0.4 nozzles. I added a thermistor for the chamber that is tucked up in the underside of the right side extrusion for the Y linear rail.
I did loosen and tighten the x rail again after resting at operating chamber temp for 30min, but only once.

No, completely stock IDEX gantry setup.

I have been printing ASA with 95c bed and 55c-60c chamber temp. (Chamber temp is monitored, but not controlled, so it will fluctuate a bit over the 20hr+ print cycle.) Even after 60+ min heat soak, I have to watch the first layer and baby step it for a good bit.

Needs to be something more thermally stable to prevent the distortion. Titanium is good. Carbon fiber would be good too.

Problem is you have a 200c-270c heater that is blowing hot air on the front side of the gantry rail in one or two locations with one or the other moving back and forth in different locations for various time intervals. There will always be localized heating and cooling happening.

Too many different materials, geometric profiles, and temperature variations.

True, but if there is a twist/bow of the x-rail, it would have to be constantly changing value based on x location on the curve, assuming the curve is a consistent and predictable arc.

And the Beacon is offset from the actual nozzle, so live reading would not actually be the nozzle location, unless it was coordinated with the initial scanned mesh and then compensated relative to current sensed height location and projected to the nozzle location. Sounds very computation heavy and messy.
