Reprapro - Mendel Tricolour

Marlin Programme onto Melzi / Sanguino w/ATMega 1284P 16 MHz using Arduino IDE.

 Objective

 To programme Marlin 1.0.7 onto a Melzi Sanguino w/ATMega 1284P 16 MHz board so that it will operate a Mendel Tricolour built 2013/2014.

 New boards has since been released to replace the Melzi Sanguino however this microcontroller is still usable on the Mendel Tricolour Reprap 3D printer and hence used for educational purposes.

 Tools

 1x PC loaded with Arduino IDE and Marlin files for Mendel Tricolour, 
2x Sanguino w/ATMega 1284P 16 MHz chip set and board (Tricolour has a Master and Slave board).
1x USB cable

 Configuration for Arduino IDE

 Files > Open > Marlin Multicolour files  
//All files including library files will be opened e.g. xxx.h//

 Tools > Board > Sanguino w/ATmega1284p 16MHz
Tools > Programmer > AVRISP MkII


Configuration for Sanguino Board to Reset and Programme

Jumper JP1 to receive only USB power.  Jumper the pin near the edge without terminals and middle pin.
Jumper JP14 to reset controller.  Leave JP1 and JP14 in this configuration until programme successfully uploaded from IDE.
Location of Pins and Connectors to Jumper or Remove during a Reset or for Programming Controller
Check for power from USB, LED will flash after 10 sec upon a connection with PC USB.

 Tools > Serial Port > Com 3                
//IDE will show Serial Port to be active//

 Process to Upload and Check Content to EEPROM

 1) Launch Pronterface > "Connect" > type G-code "M502" and "M500"
2) Turn off Power and Configure JP1 and JP14 for firmware upload. 
3) Remove Comms link to Slave
4) Plug USB to PC, Check for connectivity to Sanguino PCB thru Arduino IDE 
5) Compile and Upload Marlin thru Arduino IDE. Configure JP1 and JP14 for normal operation
6) Power up 
7) Check if values of new configuration and values has successfully been retained. Type "M501" or "M503" to check values have changed. See Specimen Results below.

Process to Offset First HotEnd Origin

 1) Test Movement of Print Head Assembly, Print Head Assembly (PHA) will consist of 1 or more HotEnd(s). 

 Command

G1 X1 Y1 F5000        // Move PHA to Home
G1 X40 Y0        // Move PHA by 40mm, First HE1 (T0) will come close to end of print bed.
G1 X100 Y100  // Move PHA, T0 to posit in middle of print bed.

2) Set the values to offset of PHA relative to Home position

 M206  X-42 Y0 F5000  // Offset PHA by 42mm with respect to Home, this should bring the T0 to the corner of print bed.   

 M500                           // Save values into EEPROM

 3) Check if values are retained in EEPROM

Travelling to Butterworth by KTM ETS Business Class Train Service On a whim, I decide to take the train to Butterworth, it has been a long time since I took the KTM's train since there was a time when the train was one of few the affordable ways to travel within Peninsular Malaysia.  It certainly definitely the feeling of nostalgia that brings me to spending approx. 5 hours to ride to Butterworth when there are direct flights to Penang.  My Journey starts off uneventfully until I reached KL Sentral.  I had an inkling that KL Sentral would be complex since several train services congregated here. At KL Sentral, visitors heading to Butterworth needs to be alert to the different entrances for boarding the train to Butterworth.  The time when I was travelling to BW, they used the holding area that is on the far side of KFC.  I sat on the wrong side (KFC) and from the sense of curiosity found the right side of the station.   At around 4pm, Snack time on board the KTM ETS Train to Butter

Tough Road ahead for 45 and Older

A Discussion on Employment in Singapore Unemployment statistics is probably one of the most closely monitored indicators of the labour market. Labour market outcomes in June 2018 improved compared to a year ago. Employment has grown. The employment rate remained high for residents aged 25 to 64, and continued to rise firmly for older residents aged 65 & over. Over the same period, the resident unemployment rate moderated for both PMETs and non-PMETs. The real median income also continued to grow in the recent five years.  MOM  Report: Labour Force in Singapore Advance Release 2018 Employment is an emotive as it affects a person livelihood and standard of living. By seeking employment, a worker more or less accepts the notion of seeking a stable income through the provision of labour.   Recent discussions on minimum wage, display of Government (G) statements on low unemployment vis a vis high number of job vacancies, calls for skill upgrade and advertisements by Minis

Births falling, but don't blame the Tiger

"Economic downturn more likely behind dip than 'inauspicious' year", The Straits Times, 27 Nov 2010, pg 1. Often effects of living in an modern urban environment invariably causes birth rates to be low. This observation is seen across a wide section of cities all around the world. What then are the effects? Popular issues include the many distraction, high cost or living, lack of support, too much expectations on limited resources. In "People Power", The Straits Times article dated 31 Dec 2010, pg A18 it was stated that the fertility rate is 1.10 children per woman and the median age as 39.6 with life expectancy at 82.1 for the Singapore population. These figures are startling considering the general call by the government to produce more against a backdrop of emerging countries to produce less. In sustaining families, it has come to expect the extended family plays an important role by which siblings and grandparents offer a means of support. Still for ma
