Wiring a Solid State Relay to Ramps

[uncle_bob]

Thanks. I bought this one: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 , but not sure when or if I will hook it up. My printer is working well with no heat bed. I am using blue tape & glue stick for PLA & PETG. Small parts I do not use the glue stick. I am almost finished a 6 hour print of a vertex for an Emmett-Delta printer & the print looks really good. I just changed my wades extruder to a titan extruder last week.

Hi

If you run the 40A relay on the heated bed, you probably should have a heatsink on it.

I have never used anything other than hairspray on glass with the Makerfarm printers. It has always worked great for everything I have printed. That includes PETG, PLA, ABS and a few odd filaments.
