I've printed noodles...

Post by b4nd1t0 » Mon Jan 27, 2020 9:15 pm

After the assembly and the replacement of few parts, i've tested the print (finally!) but the result is discouraging, this is the plate file, mentioned in the instruction manual...

Hi,You can check your z-axis step value. It is divided into 400 and 2560 according to the rebar. You need to set it according to your situation.

hi William, in the firmware I set the value to 400, I've read this post it's right? It seem the first layer is ok, but from the second the heights are not respected and they are too high.

Hi,
You don't say which rod you have on your printer...
Let's assume that you have the T8 leadscrews (These are better ! - You may want to change to them if you don't !)

You need to have '400' as the value set - as if you have '2560' then you'll just print noodles after the first layer - which is exactly what you're getting...

You need to look at your marlin files...
Open them in arduino...
You need to look at the 'configuration.h' file (TAB across the top)
About a third the way down this file you'll find the lines...

/**
* Default Axis Steps Per Unit (steps/mm)
* Override with M92
* X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
*/
#define DEFAULT_AXIS_STEPS_PER_UNIT { 79.38, 79.24, 399.91, 104.86 }

/**

(They may be {80,80,400,100} or similar - I changed mine after calibration...)

If yours says, {80,80,2560,100} then that's the problem...

Change this line and re-save to your printer...
Remember to have to REALLY tell the printer to save the new settings !
- Otherwise next time you switch it off/on then it will revert to the old settings !

Let us know how you get on.

Gerry
