CrashTestCharlie / VC4 400h Comments

My beacon doesn't give me any problems m so not sure how much help I can be. That said, first thing is to verify the hardware Is the usb to beacon cable plugged in securely? Are the heat sets in the fan duct for beacon fully pressed in? Is the beacon board tight to the fan duct and looks level to the bed? Is the usb cable at the pi plugged in securely and isn't being pulled on by cable ties? Does the red led come on when the beacon gets close to the bed?

RatOS missing from Software Updates

Check #announcements , but yeah with rc3 the ratos package was merged into the configurator package. Your system is normal. And if everything else is working, no changes are needed.

Still not enough first layer squish. The skirt lines should be flatter. Ive stopped using the save z offset. I add an adjustment to the filament gcode.

no fan spped control

Try connecting the pwm signal from the toolboard to the other wire on the fan.

Also the ace is supposedly better at the heat break, and has less for the sink to dissipate with the fan

Yeah, the part about the looseness is what made the connection for me.

Good read. Now I'm wondering if the rapido ace with the spacer block might have unintentionally solved some of this. Since the heat sink is now 3mm away from the alu plate, and the spacer is some sort of phenolic.

I saw one message in passing about someone complaining about rail friction heat. The rails weren't greased. It's a build variable

Maybe a thing, but dunno. For results like @savh is getting I wonder if the linear rail is getting hot from friction, and causing gantry bowing. The guide doesn't make a big deal out of doing a balls out cleaning and greasing of the carts. You'd need something accurate to measure the temp in the groove of the rail before starting then pause and measure quick once the layer goes to hell. A decent multimeter thermistor bead would do it.

Yeah, just move on, there's still a lot of building and wiring to do. Then grab the rc4 in about a week.
