Slow all the time at 2000% speed
-
@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?
-
@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 -
@engikeneer Its set to reprap/sprinter
-
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?
-
@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
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation ; M92 X200.00 Y200.00 ; set steps per mm M92 Z1600 ; set steps per mm Z Axis M92 E412 ; set steps per mm Extruder ; M566 X600.00 Y600.00 Z200.00 E3600.00 ; set maximum instantaneous speed changes (mm/min) M203 X18000.00 Y18000.00 Z900.00 E3600.00 ; set maximum speeds (mm/min) M201 X1500.00 Y1500.00 Z250.00 E1500.00 ; set accelerations (mm/s^2) M906 X1280 Y1280 Z1220 E700 I30 ; set motor currents (mA) and motor idle factor in per cent
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.
-
Also, in PS, filament tab, what is your max volumetric speed?
That can play a major part in speed. -
@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 It's at 0 which is default so I assume that's off?
-
@jbourns I found this for calculating Volumetric speed.

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

@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.
-
@jbourns YEAH!!!
Thanks for keeping us in the loop and letting us know when you figured it out.
-
It was either volumetric flow in prusa slicer or max speed in the config
-
@jbourns trying a different slicer and then testing 2000% let's you decide whether the problem is in the slicer region or in the config/dwc region.
