I have build my own version of open source 3d printer. Link: https://www.ultimaker.com/pages/our-printers/ultimaker-original
I have ordered those parts all over the world and many of those parts I have done by using lathe and milling machine.
Problem(Challenge) is that Ultimaker is using 19V and my non original heater cartridge is made for 12V. I have measured that when using 19V my heating cartridges's power is about 90W. It should be around 40W. 3d printer's software controls heating power using mosfet and pwm.
I have planned that I could drop heating power from 90W to 40W using Picaxe and mosfet. Maybe I will do that using ex. 10ms cycles when Picaxe controlled mosfet is on and off. Any ideas if this would be possible? Is there any things to take in to account because now there would be two mosfets between cartridge and voltage sourge.
