There are many different thermistors, which can be combined with different resistors. This result

matches the value in NUM_TEMPS_USERTHERMISTOR0. If you span definition over multiple lines, make sure to end
each line, except the last, with a backslash. The table format is {{adc1,temp1},{adc2,temp2}…} with
increasing adc values. For more informations, read
http://hydraraptor.blogspot.com/2007/10/measuring-temperature-easy-way.html

If you have a sprinter temperature table, you have to multiply the first value with 4 and the second with 8.
This firmware works with increased precision, so the value read goes from 0 to 4095 and the temperature is
temperature*8.

If you have a PTC thermistor instead of a NTC thermistor, keep the adc values increasing and use themistor types 50-52 instead of 5-7!

If you dont feel like computing the table on your own, you can use this generic method. It is
a simple approximation which may be not as accurate as a good table computed from the reference
values in the datasheet. You can increase precision if you use a temperature/resistance for
R0/T0, which is near your operating temperature. This will reduce precision for lower temperatures,
which are not realy important. The resistors must fit the following schematic:
@code
VREF —- R2 —+— Termistor —+— GND
| |
+—— R1 ——-+
| |
+—- Capacitor —+
|
V measured
@Endcode

If you don’t have R1, set it to 0.
The capacitor is for reducing noise from long thermistor cable. If you don’t have have one, it’s OK.

/** brief Maximum allowable jerk.

Caution: This is no real jerk in a physical meaning.

The jerk determines your start speed and the maximum speed at the join of two segments.
It’s unit is mm/s. If the printer is standing still, the start speed is jerk/2. At the
join of two segments, the speed difference is limited to the jerk value.

Examples:
For all examples jerk is assumed as 40.

Segment 1: vx = 50, vy = 0
Segment 2: vx = 0, vy = 50
v_diff = sqrt((50-0)^2+(0-50)^2) = 70.71
v_diff > jerk => vx_1 = vy_2 = jerk/v_diff_vx_1 = 40/70.71_50 = 28.3 mm/s at the join

Segment 1: vx = 50, vy = 0
Segment 2: vx = 35.36, vy = 35.36
v_diff = sqrt((50-35.36)^2+(0-35.36)^2) = 38.27 < jerk
Corner can be printed with full speed of 50 mm/s

Доброго времени суток.
Заказал 3D-принтер MC2. Всё благополучно приехало. После сборки принтера и прошивки микроконтроллера установил и настроил Repetier-Host 1.6.2. Подсоединение к принтеру проходит успешно. Вентилятор работает, хот-энд греется, путь по осям отображается, но шаговые двигатели не реагируют на управление.

Сразу после подсоединения к принтеру появляется сообщение об ошибке:
Ошибка com-порта:System.IO.Ports.SerialErrorReceivedEventArgs

Далее в журнале появляется строка:
echo:???????????????? ??????????????????: 0

Что это может значить и как исправить?
Пробовал переустанавливать Repetier-Host, устанавливать Pronterface. Не помогает.

Первоначально заметил, что ШД, которые были в комплекте, по названию на корпусе (PL42H48-D5) не соответствуют указанным в перечне (17HS8401J4PW550_MC5). По техническим характеристикам PL42H48-D5 его рабочий ток равен 2,4А. У используемых мной драйверов MP4988 (были в комплекте) максимальный входной ток 2А. Возможно ли, что двигатели не реагируют из-за этого несоответствия характеристик?

Заранее спасибо.
