I am using a arduino to Control my Delta Rep Rap. I have been using Cardboard since I can not get the PLA to stick to Blue Tape. I do not understand why
I have see so many people use blue tap and it works for them but PLA never sticks to the tape for me. Anyways I wanted to try the heated bed.
For some reason the heated bed will not turn on. At least no power the D8 port on the Arduino Ramp 1.4. This is the heated bed
out put correct? That's what I have seen on the web searches.. I have tried several code M190 M140 in the g code to turn it on and none have worked.
As far as I can tell I have every thing right but still no Joy. Forgot to say I am using Marlin as my Operating system.
Should I be wiring the heated bed direct to the Ramp Board? I have seen it done this way.
Should the bed be controlled with a relay? Have seen it this way also.
What is Bang Bang in marlin ?Is it fancy for an on off switching?
