i am making a college project in which i want to use a delta type printer, in which i have replaced the extruder part of delta printer and i am using it as a bed for my project.
since i have no heating bed, extruder, fan, temperature sensors, so i want to eliminate these components from the open source marlin-deltabot firmware. All i want to use is the frame of delta printer with all three motors working so that i can move my bed in all the axis. please tell me how to modify the marlin and what changes should i make.

Thank you

open the source code up and press the delete button?



why can't you just leave it be?

If you need to ask how to modify it then just do not modify it at all. The point is that there is no simple answer to your question. You need to identify the code which controls the temperature sensors and the heating elements and delete it. You need to roughly understand the code around and modify it so that the deleted parts do not brake the rest.

It does not matter that the code has functionality (i.e. the temperature management) which you are not going to use. Just leave it there.

I tried to modify the firmware but it is showing following errors while compiling.

You could try asking in the marlin forum but the devs there are busy with the latest version. Can you find some code for a delta pick and place bot? Is the extra code really a problem, just use the kinematics and leave the heater and extruder unused in your gcode.
