Hmm do you think doing a small pour last will help making it level? I think bigger mass in the pour may help make it flow even.. I would do the 2kg pour last ;)

But you might be right, just an observation!

The curing time will depend on the epoxy used and thickness of the pour.. I was scared so I waited 10 days haha

Well actually... i just poured the x- rail mounting sufaces 2x 320mmx80mm x5mm + the connecting bridge 1000mmx40mmx5mm

Total about 0.5 liters ~ 0.5kg

I have just checked.. temperature is steady at 22 deg C. Epoxy is only just starting to get solid... it is just getting real sticky now. 16hrs after pour.

The leaking epoxy was used the coat the kit seams for the big pour: bottom rail Y surface+ 2x rail x surface and bridge.

i used a small paintbrush to soak the seams and connections

about 5mx80mmx5mm of channel to fill and a 1mx40x5mm to fill.

The flow thickness of epoxy when you just start the pour is about 3 or 4 mm thick.
So yes i agree pour the whole thickness in 1 go.


I have a good feeling about keeping the temperature steady.

In the test pour there was orange skin like surface finish... no sign of that , well not jet.


The big pour i did today : shiny surfaces.

I mixed 1kg first.. then another 0.5kg.

looks like after allowing the epoxy to flow for a few hours i can see the frame straightness is good to within 2mm

Epoxy film thickness varies from +/- 6 to 4 mm

... some leaks not to bad... easy fix.


Now i need to wait a week before i can flip the gantry, clean up, and pour the last surface top y axis rail mounting surface.


Grtz.
