What's interesting is I have the Z stepping at 8 microsteps, so my Z setting of 2000 seems accurate. Also, using Pronterface, pressing the Z +10 button raises my Z axis exactly 10mm. But something is obviously amiss as, at the top of the cube I wasn't trailing 6mm of goo across the surface (There being a 6mm gap between where the top of the cube should be and where it actually was).

That was the Ultimaker robot model you get with Cura. Here's a shot of the 2cm cube.
As you can see it's a bit short and generally raggardy.

Hi, I've attached a picture of my first ever print attempt. It's an i3 with a bulldog extruder and hex hot end running ramps and Marlin. It's PLA printed at 200c and 185c for the head (more on that later)
Nozzle is 0.4mm
First print was through Pronterface, although I used the model you get with Cura of a small robot. I'm printing a 2cm cube now.
Second print of Cube has completed. It's 2cm in

Interesting thank you I'm doing my FIRST EVER print as we speak, so I've just turned the feed rate up to 106% to see if it changes anything
My first print is going... I'll stick at "is going". I'm slightly amazed it is printing something, but it looks a bit wibbly at the moment. I will still love it and cherish it like any other first born though.

Hi there, thanks, yes I've been using the official version without problem. The firmware I had issues to is linked from the RAMPS page on the reprap wiki, so I assumed it was ok.

Using either the discount LCD or full graphics, the knob adjusts something labelled as FR on the main screen. What is that?
Thank you

It's working, but I don't know why.
The Z is not doing what I expect.
I've had to change my steps per unit to:
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,2000,237}
Where 4000 is expected.
In configuration_adv.h I've been playing about. We have
// Microstep setting (Only functional when stepper driver microstep pins are connected to MCU.
#define MICROSTEP_MODES {1,1,1,16,16} // [1,2,4,

Extra info which is probably useful:
I have this martAdapter.JPG" target="_blank" rel="nofollow">LCD.
I've just uploaded the v1 release from GitHub which doesn't beep when configured with the discount lcd, but as everything else is (almost) default, there's more work to do to configure it. Any advice at this juncture would be great.
Cheers

Hi,
I've just updated my firmware to the firmware found on the this page -> here.
I have an LCD board attached which has the piezzo speaker. When I power up now the speaker makes a high pitched whine. It's attenuated (?) to the load on the power supply I think, so it becomes louder or quieter depending on whether I'm moving the motors. It becomes very loud when I power on the PSU (I had the

Excellent guide. Thank you for that. Fingers crossed I'll be up and printing this weekend

Yes, with three on each, I have silky smooth but very slow (scaled down) movements. Curiously the printer also hits an invisible max stop in all axes.
So two questions:
1) How do I ascertain what level of microstepping I require?
2) Will this necessitate a change in the Marlin code? I have another question related to Marlin which I will ask in the correct forum.
I've found the table defining t

This mentions them, so I'm going to try with three on each and see what happens. I'll update once I do it.
Thanks

Ah... Jumpers? I didn't configure any jumpers under the drivers, but now I think of it there are pins on the RAMPS under the drivers which I meant to look up. Do you have any idea how they are configured? I'll try and find some clues independently, but it's not in any of the build docs I've read so far.

Thanks again, that seems to have solved the first problem. I changed the X/Y to 300 which works a treat. Z I had to change down to 10. Any high and it won't work. I assume this is because one revolution of the motor spindles in Z represents less distance than one turn of the X and Y motor spindles.
Interestingly, the home buttons (sort of) work. X and Y do a high pitched whine, then suddenly wha

Hi there,
I'm building an i3, it's mostly complete. Electronics are Mega 2560 + ramps 1.4 running marlin. FYI I bought it all as a kit from these people via Amazon. It's been a mixed bag so far, but I'm generally pleased.The printed parts aren't great quality, some of the bits are wired wrong (end stops) and the instructions stop just after the basic frame construction, but all the bits were th
