Educate Me In 3d Printing

Honestly I would not rewrite the software. Marlin is open source and probably 95% of the printers use this. They've done the hard lessons so use that. Also be careful with going overboard work your heaters especially if you are going to use your own software. There have been a few people who have burnt down their houses even with a single 40w 12v heater. Temp sensor comes loose so the software has no feedback and just drives the heater which melted the aluminum heater block which ignited the plastic model below it. Marlin has support for safety here, also has software PID heater controller and many other lessons learnt.

I will be using a 1440 watt AC heater on the build plate and and an AC cartridge heater for the print head using PID controllers for both, which I'll tie back into the computer. They will also have a thermocouple loss safety shutdown programmed in.

As far as rewriting the software, it's not much of a rewrite. I just need to adjust the code to handle the print head. Which means ''gearing'' the print head axis (W) to the X+Y+Z vector axis (S axis). The print head needs to run at a programmed speed that is a function of the S axis vector speed under G-code control

The drive hardware is already installed in both of my machines as is the operating software.
 
Make sure you secure your extruder at 200+c not at room temperature, as mine leaked like crazy until I remembered how hot this dumb thing is really getting and snugged it up at working temp.
Quoted for emphasis.

This caused me MUCH headache.
