I’m lucky enough to own a few 3D printers, and largely in this modern era, they work really well without too much tinkering and optimisation.Most of the time my printed results are close enough and I don’t get too hung up on calibration.When I do need higher dimensional accuracy one of my starting points is to check the diameter of the filament and then calibrate my extrusion and flow rates accordingly.
It’s quite interesting how variable a nominally 1.7mm filament can be.The bdwidth is a device you can place in the filament path and it will constantly check the filament width and report the filament motion; combine it with a Klipper-controlled machine and it will automatically adjust the flow rate to constantly match the filament properties.It’s an interesting device.
Powered via USB, the onboard screen gives live feedback to the user.Its optical system can return filament dimensions to an accuracy of +- 0.015mm using a high-resolution CCD sensor.It also has the more common filament sensor functions built in such as jam detection and it will detect run-out situations and again can link to Klipper to pause the printer on detection of these conditions.
There are options to connect this back to your machine via USB or I2C, and the USB port can also be used to update the firmware.Over on the repository, there are instructions on how to install this into Klipper which looks really straightforward and a Klipper config file addition is also supplied.So if you want to optimize your prints just a little bit more, check out the bdwidth and let us know what you’re printing with it!
