Re: Hot end temperature variation when bed is also on

I've double and triple checked my wiring over the past few days, and disconnected and reconnected everything. Unfortunately to no avail.

Good thinking! I tried exactly what you said and it had no trouble heating up and holding a constant temperature.

So, I'm going to order a new ramps 1.4 board and try it out. I'll let you know if it does the job. Thank you for all of your input and help!!
