Hi,
Had many troubles with a kit I purchased early december. This is a P3Steel based kit with RAMPs. Just soldered the 14awg heatbed wires on and checked resistance. I'm only seeing 0.7Ohm? I thought this was a short but nothing visible and no shorts to the aluminium. Checked the expected load and wattage and it is neatly 200W (allowing for errors) and would draw 17A. The neatness to 200W leaves me suspecting this is as designed and the tracks do seem wider than my other secind hand mk3 bed.
Any one else seen these high current 12V beds?
I'll raise the issue with the supplier too.
