Heatbed slow in heating Hello everyone, I have a Prusa I3 printer which is working very fine. But I have a horrible time to wait until my heatbed is on temperature. Sometimes I have to wait for 45 minutes to come to a 110 degrees Celsius. I have chenged the wiring to thick ones, but doesn't fix it. The heatbed is connected to a Megatronics V2 board with 12V output tot the heatbed. Almost no drop of voltage to the heatbed. Thermistor reading is good. Does anyone has a suggestion to get this solved to a faster heating time? https://reprap.org/forum/read.php?1,315399,315399#msg-315399 Tue, 06 Oct 2026 05:59:17 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,315399,316068#msg-316068 Re: Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,316068#msg-316068

also check the voltage both at the bed and at the psu. You would be supprised how much difference there can be running at 11.5v rather than 12v

In the Dutch forum I read that the voltage of Hill's PSU drops 0.25v when heating up.]]> Ohmarinus General Tue, 25 Feb 2014 15:34:27 -0500 https://reprap.org/forum/read.php?1,315399,315803#msg-315803 Re: Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,315803#msg-315803 lazzymonk General Tue, 25 Feb 2014 06:49:38 -0500 https://reprap.org/forum/read.php?1,315399,315726#msg-315726 Re: Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,315726#msg-315726 [www.ebay.com]]]> olisoft General Tue, 25 Feb 2014 02:50:56 -0500 https://reprap.org/forum/read.php?1,315399,315521#msg-315521 Re: Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,315521#msg-315521 ayouden General Mon, 24 Feb 2014 15:45:35 -0500 https://reprap.org/forum/read.php?1,315399,315502#msg-315502 Re: Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,315502#msg-315502 NewPerfection General Mon, 24 Feb 2014 14:47:37 -0500 https://reprap.org/forum/read.php?1,315399,315399#msg-315399 Heatbed slow in heating https://reprap.org/forum/read.php?1,315399,315399#msg-315399
