if it's a corexy and you're running it at 60mm/s - then hell yeah you can make it go faster.

For fine derail stuff it should be good for 76-100 mm/s and for rough-ish 'useful' prints 150-200mm/s.

The key thing is to make sure the belts are as tight as you can get them.
With each belt being so long and going through such a convoluted path - it can be tricky to get them tight. If you look on thingiverse there should be mods to help tighten the belts.

Also if it's not already direct drive - change it to direct drive.
Should be a fairly simple job - usually just a printable bracket that allows you to bolt the extruder assembly on top of the hot end.

And maybe try a different slicer.

But 60nn/s is seriously slow for a corexy.

Is it still in the 'box'.

And my brain is now telling me it's already direct drive - so that's good.

Hotend is fine. pretty much bog any standard hotend is good for 150mm/s at 0.3mm layer height.
Well mine are and they are certainly nothing special :-)

You don't actually need to up the temp much either.

for pla.
For 150mm/s at 0.3 layer I usually run at 210c.
for 150mm/s at 0.1 later - I'll run it at 200c.

Different filaments are happeir at different speeds.
so what filamet type are you porinti ng at 60mm/s

And the reason I use mm/s rather than mm per minute is quite simple.
I can envisage 60 mms travel in one second. I cannot envisage 3600mm in a minute.

You can move your finger against a ruler for the count of 1. and clearly see how fast it is.
You can't do that for mm per minute.
