Some thoughts:-
You make a good observation there, and I think might be near to the issue.
Here is the old nozzle:
New nozzle:
As you can see, the older nozzle is wider and flatter.
Reducing the overall extrusion rate to 92% did not make a difference to the issue. I flipped the Z rods, which also made no difference.
I will try reducing the infill rate only to 90/95% an

When you say 'solid' infill, is that 100% infill,
Have you tried reducing to say, 95%.
Yes, sounds like over-extrusion to me, and on the 100% fill layers the only place for the excess to go is out the sides.
Alexander, have you done the fine extruder calibration as described on the following page:
Interesting. I have done this when I replaced the extruder and hot end (

Yes 100%. The odd thing is, I have been able to print this model with 100%infill previously.
Are you saying reduce the flow rate to 95% or just the infill percentage?

Z axis not moving far enough doesn't explain why the center section turns out ok, or why your 40mm high solid cylinder doesn't fail. You could check for that though, at least partially, by (1) measuring the height of your objects with calipers to make sure they aren't too short or (2) taping a pencil to your extruder horizontally and drawing a line on a vertical object with a piece o

The hotend fan works well, I thought that it might be overcooling of the print, so I rotated the heatsink to the ends blew forwards and backwards instead of up and down. No difference.
Yes, I have the same issues with 3 different types of filament (see the black and gold) I also have a green colour change that has the same issue.
Surely if it where heatcreap, it would look like underextrusion?

Sorry, didnt see the response.
Tried slow it right down. Makes no difference. The filament is being fed consistently, no issues with that.
I have also, installed a glass bed, no difference.
New bearings on all rods, no difference
new stepper driver on the Z motors, no difference.
I can print a calibration circle (entire bed width) without issue.
I can also print a 30mmx40mm high solid cylin

Hi all
I have a pretty modified Monoprice maker select. Its running on a ramps board with the repetier firmware. I have been printing happily through many many spools of filament (mainly ABS).
I recently had some issues where my extruder would underextrude randomly through the print, mainly larger prints. After much faffing around, I replaced the whole hot end with a china special. Works well e

As a follow up. It turned out that I overwrote the boards bootloader. I purchased an AVR Mk2 ISP and flashed the firmware on via that method and the board is now working properly.

HI all
When compiling Repetier (latest version) in Arudino IDE 1.0.6.I am compliting for a Melzi 2.0 board.
I get the following error:
SET_INPUT(SDCARDDETECT);
Printer.cpp: In static member function 'static void Printer::setup()':

Repetier
Hi all
I have a monoprice maker select 3d printer that had the stepper driver on its board go pop.
After a bit of research, it appears its a Melzi board.
This is the one that's in my printer:
This is the Reprappro Melzi V2 board I have bought to replace it:
I am having issues writing the Repetier firmware to this.
I have the right board showing up in the Arduino IDE (v.1.0.6), the boar
