I have tried to find this post but with no luck

Can anyone help me find it

How do you program in gcode is this something that is easy to do or is it something that is difficult to do and learn

“ I reprogrammed the gcode to get a better controlled slope where required and max output for when the required temp gain is closer to 1.4C/sec. Pretty happy with the slope. Near term I'm going to have to add at least a buzzer, longer term a stepper to open the door. “


What I have in mind doing is use a Ender 3 controller board and use the heater extruder output and the heater bed output to control two heating beds or heating bed and a heater element ( at this point is just an idea but I want to see if concept is do able or not )

For circuit board warmer that have many layers so removing components might be easier to remove

Is there a way to 3D print letter and numbers if so what software do you use to create these items

Are you talking about using your 3d printer to pre-heat boards? I don't think those will get hot enough. And with the hot plates, you don't really need to do a profile, you just need tight temperature control (pid). You can do that with just an arduino, a thermistor and a heater. I have been meaning to put something like that together, I just haven't gotten my hands on a thick piece of aluminum yet. You could even pick up a cheap electric resistive stove and goodwill and rig it up with an SSR and a thick aluminum disc to spread the heat. It's not really worth the complexity of running klipper on a hotplate, because you really only need the PID control and one set point. You aren't doing trapezoidal reflows, etc.

Do you have an arduino? You can pick them up for $3 or so, and there are plenty of libraries, including pid libraries that you can use.

For adding text, which I really, really avoid doing because unless it's big, it doesn't print well, I use openscad. I haven't figured out how to do it in freecad yet. Here's an example or how to do a nametag in openscad (not mine). Openscad is more like a programming language than a cad software like freecad.

Also, chinese pid controllers are really cheap now, you can pick one up for $10-15. Really not bad, comes with an LCD display and controlls too. Almost not worth building your own unless it's for fun.

If you go this route, make sure the thermocouple is the right kind for the controller.
