第十步：Q & A
Step 10 - Q & A
1.What must the consistency be so that the M500 can cope with it?
The noise is caused by the putter not being able to push the clay. The reasons for the noise may be: 1. The clay is too hard, you need to continue to add water to the clay. 2. Or
the clay conveying system is blocked, you need to disassemble and clean it.
Since the specific composition and proportion of clay varies from place to place, the hardness of clay needs to be adjusted according to the actual printing situation. Even if
your pressure is 2.5kg, it may be difficult to extrude, because we have to consider factors such as the fluidity of the material. For example: under the same 2.5kg pressure, China
Clay has a higher printing success rate than Red Clay, because China Clay has better fluidity and China Clay dries slowly.
The hardness, fluidity, and printability need to be adjusted according to the actual situation. Make the clay as soft as possible and have better fluidity, which is conducive to suc-
cessful printing.

2.What kind of noises of the printer are normal? I noticed that as soon as the printer starts its paths, the two motors of the Z-axis "tremble" they turn slowly and trem-
ble? is that normal?
There are many reasons why the first layer cannot be completely fitted. Here are several solutions:
A.
At the beginning of printing, observe the printing status of the first layer. If two adjacent lines do not fit completely, you can enable the Babystep setting. Fine-tune the Z-axis
distance on the screen operation interface, as follows: Option->Babystep->Z-. If two adjacent lines fit too closely, fine-tune the Z-axis distance on the screen operation inter-
face, as follows: Option->Babystep->Z+.
On the Babystep interface, do not click Z+ or Z- multiple times, which will easily cause the Z value to be disordered and the Z axis not to drop. It is recommended to select an
appropriate stroke (0.01, 0.05, 0.1), and click several times to complete the Z-axis adjustment.
B.
In the pre-extrusion step before printing, let the electric push rod perform sufficient pre-extrusion until you hear the abnormal sound of clicking, and stop the movement of
the electric push rod immediately. In this way, when printing the first layer, the clay can be fully extruded, and two adjacent lines fit closely.
Clay is a non-Newtonian fluid, and the relationship between shear stress and shear strain is nonlinear. That is to say, when the clay is pushed, the clay will not respond immedi-
ately (such as deformation and extrusion), which leads to the hysteresis of clay printing.
The hysteresis here causes the clay without enough flow to be squeezed out when printing the first layer. Sufficient pre-extrusion can make the pressure of the clay in the feed-
ing system strong enough. Once the extruder rotates, the clay can be extruded smoothly, and the first layer can be printed perfectly.
For the trembling problem of the Z-axis, you can apply grease on the Z-axis screw rod (this grease can also be used to push rod of the electric push rod to reduce the wear of
the push rod). In the standard packaging of the Matrix, a tube of white grease is carried.
However, the item was taken out due to reasons such as logistics providers and customs policies. If you cannot find the item in the packaging, we recommend contacting your
local retailer for similar products.
3.XY returns to the home position abnormally and makes a clicking sound.
Please check whether the limit switches of the XY axis are normal? Is there any bending? Has the wiring harness fallen off?
