Extruder r-e-a-l-l-l-y slow after Marlin upgrade

Hi.
I have RAMPS 1.4 on a CoreXY (wip)

I recently upgraded my Marlin firmware to 1.0.2 (latest stable) from 1.0.0

I first thought the extruder motor wasn't turning at all but it does move slowly. About 1mm per second. It does extrude the requested distance (eventually)

It sounds like 'user error' to me too, but I've checked and double checked every parameter between the 2 configurations that I can find.

I've doubled DEFAULT_MAX_FEEDRATE from 25 to 50 mm/s with no effect.
I've tried M502/M500 commands from pronterface to update the EEPROM settings

The old firmware works fine if I reinstall it.

Any suggestions?

Thanks

Alan

Sounds like a bug in Marlin. Likely thes appreciate a bug report on Github along with a (short, if possible) section of G-code.

Thanks.

What section of G-code?

A

Do you use the latest firmware with that config.h?
There is an update for multi-extruder setups. Maybe there is something wrong.

Get the latest firmware and test again.

Thanks Wurstnase

I only downloaded the firmware 2 days ago and modified the new config.h
It was standard Marlin not X2
I may try another download in a few weeks.

I can speed up the extruder within Pronterface but I cannot from the Graphic controller (Reprap Discount full graphic smart controller)

Which gcode do you sent?
Can you upload your config.h?

Config attached.

I should have said that I've not tried printing yet.

The problem is when using the move axis command from the LCD controller.

Thanks

SOLVED! (ish)

Configuration.adv.h has a few lines at 237-240


// Feedrates for manual moves along X, Y, Z, E from panel
#ifdef ULTIPANEL
#define MANUAL_FEEDRATE {50*60, 50*60, 4*60, 60} // set the speeds for manual moves (mm/min)
#endif


I upped the 4*60 to 40*60
which worked after a M502

I'm not fully satisfied.

I'm sure the feed before was about a mm/sec not the 4mm/sec as implied above. It seems (unscientifically) to be a bit quicker than 40mm/sec (test to follow)
I haven't got the 'Ultipanel' defined. Or does that somehow apply to all LCD panels?
The old Configuration.adv.h didn't have the feedrates option above, so I don't know where the feedrates were derived from before.


I'll call it fixed. But it's still a bit vague to me.

Thanks for the suggestions, anyway

Regards

Alan
