Hi every body , I'm new here and this is the first time I post something in a forum , and I'm a newbee in electronic and 3d printing. I have a Prusa i2 printer with a Gen6 ramp board ,I would like connect a MK2 heatbed on this board , I have found a tutorial on wikipedia 6 Spare pins for extension I could be able to do the wiring alone but for the programming of the board I don't know how to modify the firmware , I have an arduino program application but I don't know wich file to put in for modifying the firmware. Thanks for helping and sorry for my bad frenglish . ^^ https://reprap.org/forum/read.php?1,445835,445835#msg-445835 Fri, 14 Aug 2026 02:50:25 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,445835,446115#msg-446115 https://reprap.org/forum/read.php?1,445835,446115#msg-446115 Zaka 67 General Sun, 21 Dec 2014 07:00:46 -0500 https://reprap.org/forum/read.php?1,445835,445990#msg-445990 https://reprap.org/forum/read.php?1,445835,445990#msg-445990 Zaka 67 General Sat, 20 Dec 2014 16:53:08 -0500 https://reprap.org/forum/read.php?1,445835,445969#msg-445969 https://reprap.org/forum/read.php?1,445835,445969#msg-445969 Have you any advice for a good board with dual extrusion possibility , and not to hard to handle with, can I use my arduino board to control my printer?]]> Zaka 67 General Sat, 20 Dec 2014 15:39:02 -0500 https://reprap.org/forum/read.php?1,445835,445941#msg-445941 https://reprap.org/forum/read.php?1,445835,445941#msg-445941 there are instructions available here: [reprap.org] look in Compiling new Firmware section


from the tutorial page it states
Once you have all the circuits setup to use the pins you can simply define them in the Gen 6 part of pins.h. For Marlin I made the following modifications, my pins.h is also shown below.
Below "#if MOTHERBOARD == 5" (ie not deluxe), set HEATER_BED_PIN to 16 or 17 (depending on your choice) and TEMP_BED_PIN to 0
Set #define SDSS to -1
Set Fan_PIN to 17 or 16
You must also specify to use software PWM for the fan otherwise the fan can only either be on or off, just call #define FAN_SOFT_PWM somewhere
The type of thermistor you are using for the bed must also be defined in Configuration.h as shown below.



a clear warning here. if you are ok with the time and effort realize that this may not go as planned, firmware may not compile correctly, common support is not available and you may find that you need to learn c++ just to correct a few lines of code for your own uses. if this is a task you are not willing to be able to handle, then I would spend 40-80$ for a new board type that supports heated beds, because in the end that is what you may do because you will likely be spending 20-80hrs on this learning project. well worth it if you intend to learn about programming, and electronics,]]> jamesdanielv General Sat, 20 Dec 2014 13:43:19 -0500 https://reprap.org/forum/read.php?1,445835,445835#msg-445835 https://reprap.org/forum/read.php?1,445835,445835#msg-445835
