Slow all the time at 2000% speed

Jbourns

I've cranked my max accel and speeds up and nothing its just staying at 24mm/s

@jbourns if you use Cura, disable acceleration control. It uses mm/sec for acceleration and speed as Marlon does, but RepRapFirmware uses mm/min.

Jbourns

@oliof Im using prusa slicer!

this is what i have in the speed settings.

jens55

How do you test maximum speed? do you just run a model? If you run a model, what are the slicer settings for max speed, acceleration and jerk.

You could take the slicer variable out of the equation and just use a quick hand written macro such as :
G1 X000 Y000 F50000
G1 X000 Y300
G1 X300 Y300
G1 X300 Y000

Adjust the F parameter to suit what you want the machine to do
Adjust the coordinates based on what your printer bed size is.

Jbourns

@jens55 By printing things usually dialing up with macros. But nothing is increasing the speed at all, it'll go slower.
right now i dont care for setting the proper speeds. I just want to go faster than 25mm/s 2000% speed should have done something.

Should the print speed in dwc override what the slicer?

engikeneer

@jbourns what firmware flavour do you have set in PrusaSlicer? Should be Reprap.
If you leave it in Marlin, it puts a bunch of max speed commands in the start code in the Marlin units, so you end up 60x too slow

Jbourns

@engikeneer Its set to reprap/sprinter

PaulHew

How big and what are you trying to print?
If it is small and complex it might not be able to get up to speed.
When I print Pi cases my infill is going at 130mm/s. 3 perim, 3 top and bottom.

Got an stl?

Jbourns

@paulhew Its 38 x 45mm. I just don' t get why it wont increase in speed at all from DWC. I've always been able to crank it up to suit my needs. Now I'm stuck with a 6 hour print when it should have been done in 20min

@jbourns This is my speeds config for a RailCore

My E speeds are higher.
I run a BMG Extruder with a mosquito hotend.

I will give you part a run later, nearly 1am here in the UK.

PaulHew

Also, in PS, filament tab, what is your max volumetric speed?
That can play a major part in speed.

Jbourns

@paulhew I'll give those a go, Thanks for the help. I'll be testing them in the next hour once this part is printed.

PaulHew

@jbourns

Jbourns

@paulhew It's at 0 which is default so I assume that's off?

PaulHew

@jbourns I found this for calculating Volumetric speed.

Jbourns

@paulhew 10mm/3 seems like a good middle ground for the volcano

Jbourns

@paulhew The only explanation is that im a daft prick. I think i fugged up my E speeds ands acceleration at some point. Doesn't explain why I couldn't just override it.

dc42

@jbourns the speed multiplier will override the speeds requested in the F parameter of G1/2/3/4 commands, but not the machine speed limits set by M203.

alankilian

@jbourns YEAH!!!

Thanks for keeping us in the loop and letting us know when you figured it out.

Jbourns

It was either volumetric flow in prusa slicer or max speed in the config
