√ Hackaday | Forcefulness Sensitive Resistor Takes The Hurting Out Of Bed Leveling

How practise you lot know if your 3D printer bed is levelled? Oh, don't worry – you'll know. Without a marking bed, filament won't stick properly to the construct surface together with you'll function into all sorts of other problems. Knowing how tricky it tin endure to become the bed merely right, [Antzy] built a tool to help.

The device, which he calls the FS-Touch, is based roughly an Arduino Pro Micro fitted amongst a forcefulness sensitive resistor. This allows the distance betwixt the bed together with nozzle to endure measured based on the forcefulness read past times the resistor when placed inwards betwixt the two.

Using the tool is simple. First, the bed is brought roughly into alignment using the typical newspaper method. Then, a reading is taken from i corner of the bed, together with the measuring saved for reference. The other corners tin together with thence endure laid upwardly to the same level, amongst the assist of LEDs to guide the user inwards which direction to plough the adjustment knobs.

Measuring forcefulness inwards this trend has the potential of beingness to a greater extent than repeatable than the somewhat hard newspaper method. It promises to repose the chore for users that may endure struggling to become their bed inwards proper shape. Of course, automated bed levelling makes things fifty-fifty easier again. Video later the break.
