Thermistor for M200 (Select Mini)

Original hotend and heat bed are both 100K NTC resistor with beta 3950.
The stock hotend thermistor uses a glass bead thermistor.
The stock heat bed uses a SMD thermistor but can be easily replaced with a glass bead type. \\

A few stock replacement options listed below.

As of motion controller firmware version 26 the MP Select Mini is no longer limited to only using 100K NTC thermistor with Beta 3950 for the hotend. Version 27 added this ability to the heat bed.
With custom G-code command “M561” the thermistor type can be changed for the hotend and heat bed.
The hotend and heat bed can use different type of thermistors for each.

M561 - Change thermistor type

See the Extended G-code Table page for instructions on how to use custom G-code command "M561".

Type P0 = Default or EPCOS 100K
EPCOS 100K thermistors B57540G0104F000, B57560G104F, and B57560G1104F have similar Beta values compared to the stocks Beta value of 3950. Because of this you can use B57540G0104F000, B57560G104F, or B57560G1104F as replacement thermistors. Type P0 is used for the stock thermistor and the previously mentioned EPCOS 100K thermistors.

Type P1 = 104GT-2 or 104NT-4-R025H42G
Characteristics of 104GT-2 and 104NT-4-R025H42G are nearly identical. Type P1 is used for either thermistor.
