Speed

[remote burrow]

I didn't think I'd get this far

[plain grove]

Maybe some day

[remote burrow]

God damn
What would you say were some of the most important upgrades to get there?

[plain grove]

Fans and hotend 100%

Then if you want quality: dual z, pei bed, extruder

Then for speed: board, firmware, and last, motion systems

[remote burrow]

My hotend good for now
Fans are awful atm though
Can you elaborate on the board bit? And how important is dual Z?

Also what accel is that

[plain grove]

So the stock board has 2208 drivers, maybe even worse depending on what board you have

[remote burrow]

I'm pretty sure I have a 422

[plain grove]

With 2209 drivers you can use almost double the amps

With increases stepper torque a lot

[remote burrow]

Are you cooling the steppers/ did you replace them?

[plain grove]

Dual z is good for consistency, so if you ever have parts looking like this

[plain grove]

Yea, I swapped my y at least, to a bigger one

[plain grove]

That was 300/50/10k with 15 jerk

[remote burrow]

I see
What should I upgrade first then?
It looks like I'm limited by cooling and some kind of extrusion problem maybe because of bowden

[plain grove]

Depends, how much do you want to spend on mods total?

Or not really any limit, just looking to mess around?

[remote burrow]

Probably spend the least possible
At the moment I'm just trying to find the best way to push it just a little further

I think a toolhead overhaul is due though

[plain grove]

Alr, that's about the same boat I'm in

Then definitely get a cht nozzle if you don't have one, and do fans, I'm running dual 5015, and a 4020

[remote burrow]

At 8000 max accel atm
Klipper uses 6000 90% of the time

Cant see any issues aside from Y stepper getting decently hot and the extrusion issue I mentioned earlier
It's weird though, like if pressure advance isn't working properly

Also what's your extruder accel?

[plain grove]

Hmmmm, I don't actually know, I think 6k maybe

4k

[remote burrow]

Mine is at 4k too

[plain grove]

I haven't messed with it though

[remote burrow]

I think the Bowden is the problem
Yours is using stock repurposed direct drive?

[plain grove]

Yes, at the moment

It works better than the bowden, but I'm getting a sherpa soon

[remote burrow]

I was gonna buy a orbiter but after seeing that speed on a bulky stock direct drive I might try that instead

Do you have a link for that toolhead stl?

[plain grove]

Let me see...

[remote burrow]

One more thing
I haven't touched my amps yet
Could I bump them a little on the stock board? And by how much?
If I'm at 8k I might just barely be able to reach 10k

[remote burrow]

Thank you

[plain grove]

they can handle 1.2 amps, which is about 1.4 vref

[remote burrow]

Where would I even change that? Printer.cfg?

[plain grove]

na, you use the potentiometers on the board with a mulimeter

[remote burrow]

Ah I see

[plain grove]

You turn these little screw things

It kinda sucks to adjust if you don't have alligator clips lol

[remote burrow]

Yeah I just have prongs

Was really hoping it was like the qidi where you just tell it to change the amps

[remote burrow]

Does the 422 board have space for an extra blower?

[plain grove]

You just split the wire that goes to the 4010 blower

[remote burrow]

That's it?
So you don't even need to open the bottom panel?

[plain grove]

The 422 only has 3 fan ports

[plain grove]

Nope

Just cut the wire going to the old fan, solder the 2 blowers together, and solder them to the old wire
