I seamed to have fixed the problem, I will hopefully accurately describe what worked if anyone else is having issues. Try changing (uncommenting) the three preconfigured hot ends to find one that is close, then run an PID tune to get the values as close as possible. Link below Thanks for your help Flurinby JackDavies - Firmware - mainstream and related support
I tried the different firmware but nothing changed. This is getting stranger! I changed the preconfigured code for selecting the hot end to the Makergear one to see what would happen. It started of looking good as it stayed at ambient room temperature, I then did the het to 50C in pronterface and it got there and stayed constant for about 5 seconds. Unfortunately it then dropped back down to abby JackDavies - Firmware - mainstream and related support

I downloaded it yesterday evening, the motherboard settings again has no impact. Would it be something to do with the PID Bang Bang settings? Jackby JackDavies - Firmware - mainstream and related support

Hi, I have tried that but nothing changes. It is strange because its working fine with sprinter and marlin being based quite heavily on sprinter I can't seam to find what's wrong!! Any other ideas? Thanksby JackDavies - Firmware - mainstream and related support
Hi, Thanks for your quick reply. I am using a modified scratch built ultimaker hot end. Config file is attached. Kind regards, Jackby JackDavies - Firmware - mainstream and related support
Hi, I am trying to get my hot end to heat up with ramps and stay at a constant temperature. However in Marlin the hot end resistor will automatically start heating and I have measured 12v on the D10 connector of the ramps board. The thermistor shows the correct temperature of the hot end and it goes to about 100-150C before lowering back to ambient. It does this when i power the board and not whby JackDavies - Firmware - mainstream and related support
Hi, I am half way through a DIY Ultimaker build and have come to order parts for wiring (I have already assembled my RAMPS 1.3 board) I want to use some kind of panel mount connector for the power, however everything I have looked at is rated way to low for the amps I want to pull through (I am using a heated bed & single extruder). I wanted to use this figure of 8 panel mount and make a fiby JackDavies - RAMPS Electronics
