I don’t believe anything has been printed on this mega fast machine.
Actually this is the 3rd iteration of this machine. The previous version use the standard 6 mm belts and they weren't strong enough we stripped a few teeth off of them at 1.6 amps

We are now running 12 mm belts on everything with the 148 oz in servos.

I could also see the harmonic from running the y-axis belt on the tooth side so I am now running it smooth side cross two points before it moves the hot end.

Now we should be good to run them at the full 2.8 amps.

Rigidity is everything.

I have all the wiring for the hot end I'm finishing making the chain way for the new Hemera carriage.

I should also note that you need to be really careful. Early on with this new build I kind of goofed during homing.... bent the two X limit switch brackets made out of angle auminum.... like they were paper.... before the windings melted....

Always be careful where your arms and fingers are

Did a couple upgrades and some maintenance..

Swapped from springs to silicone feet and added the anti-backlash but for my Z rod. Then cleaned the rod and put some Teflon dry lube on it.

And the results I am pretty happy with. Made quite the difference on my Z issues. Much smoother prints and way less Z binding. I still need to tune my accel/jerk settings to the new hotend. I've been running it around 60MM/s for everything and can print successfully at 100-120MM/s... But the quality just isn't there yet without tuning.

Left is after upgrades/maint. right is before.
