The mosffet card is good for the extruders, but Silvia won’t go to beds with this card (4 x irf540n)!!
Any advice?vicious1KeymasterAugust 15, 2016 at 1:16 pmPost count: 2627
Heatsinks, big ones! Try insulating your beds (So they draw less power to warm up and keep at temp), maybe even get them up to temp one at a time (so they dump less heat into your heatsink at the same time). Once at temp I would imagine they should be fine.
I think You might actually have to go to something more efficient than those mosfets if a heatsink and fans don’t work.RuiParticipantAugust 15, 2016 at 1:41 pmPost count: 43
Hi V. This happened in 30 sec :D. These irf540n mosfets have a lot of internal resistance (44mOhm). Trying stick a mosfet from a Ramps on the red board (irf3205 – 8mOhm).
Feedback on this soon.
Maybe wrong topic, sry… could U move it to Q&A?
