Looking to upgrade My heatbed MK2A-ALU 3mm Heatbed- Has anyone used? Recommend? I am looking to upgrade the heatbed/printing bed on this printer. It has under 1 resistance which is a headache to use. I have been searching online for any information I can find about the Heatbed MK2A-ALU Heatbed or one similar. The only information I can find is that people have issues with aluminum heat beds warping after a few uses. These posts do not specify if it was the 3mm thick version. Any one use or have any recommendations? https://reprap.org/forum/read.php?13,340166,340166#msg-340166 Thu, 16 Jul 2026 01:31:12 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,340166,372677#msg-372677 Re: Looking to upgrade My heatbed MK2A-ALU 3mm Heatbed- Has anyone used?

I find that it takes over 15 minutes to get to 100C... anyone else? direct to 12V 40W switching power supply...
I'd suggest using a larger power supply. ;)]]> cdru Controllers Tue, 17 Jun 2014 15:46:20 -0400 https://reprap.org/forum/read.php?13,340166,370774#msg-370774 Re: Looking to upgrade My heatbed MK2A-ALU 3mm Heatbed- Has anyone used?

Could the people complaining it's slow be hooking the 12V up to the 24V pins?

Also, if you're using electronics that have a PTC fuse, you may find that at high currents the fuse is dropping a volt or so. You might want to look at replacing the PTC fuse with a standard in-line fuse. Measuring the voltage across the bed at the electronics end is also a good idea (as is at the board itself - you could be losing volts in your wiring).]]> Cefiar Controllers Wed, 28 May 2014 03:35:09 -0400 https://reprap.org/forum/read.php?13,340166,361299#msg-361299 Re: Looking to upgrade My heatbed MK2A-ALU 3mm Heatbed- Has anyone used?
