<p>I faced some problem with my 3D printer device. It seems the bed warms up without any problem, however, the hotend does not warm up! </p>

<p>Could you please help me identify what the problem is? </p>

This could be a number of things but i would start to double check the pinout in your code vs the pins on your mainboard and measure if it gives 12v/24v (depending on your PSU) output.</p>\n\n<p>There's a lot more info required to properly help you.\nWhat board are you using?\nWhat OS are you using?

If you are saying the numbers are not showing (like when it is heating, the number on display or octoprint says 0/180) this could be a Thermistor problem. Check to make sure if your hot end is heating up by putting a paper or filament under it. DO NOT touch with your hand.</p>\n\n<p>Second, If your hotend is truly not heating up, then several things can be happening.</p>\n\n<ol>\n<li>Your hotend is wired wrong. Make sure your board is correctly wired. </li>\n<li>Your hotend is dead. Change to different hotend and see if it works.</li>\n<li>Your hotend is not getting enough power. </li>\n</ol>\n'}]
