In MrCarlsonsLab’s electronics tutorials, the detailed design and build of a simple oscillator circuit is shown. To assess the quality of the oscillator, the Total harmonic distortion is measured using a Spectrum analyser… I don’t have one… But on my bench there is a Rigol DS1054Z (opened up to 100MHz). It can do FFT. It’s […]
I just finished drawing the circuit for the main PCB of the Kenwood Breadmaker BM-256, which I will need in a separate project. Here they are. Maybe someone finds them useful: Kenwood_BM256_schematics.
9 point bed levelling was not enough apparently. As the layer height decreases for better prints, the 9-point routine described before was not good enough. The next easiest and logical step was to increase it to 17 points. This method will immediately become obsolete once the final release v1.18.1 of David Crocker’s firmware comes out, […]
My old HP/Agilent 54820A Oscilloscope produces an error during every single boot. After it has been switched off it always looses date and time and all CMOS settings. It does continue to boot up after asking for user input. This is because the CMOS battery that keeps the CMOS settings is flat. Most 54810A, 54815A, 54820A […]
It is a misconception that baking bread is time consuming. In fact, the time spent working on the bread is less than taking the car to a shop that is 1 mile away. Starter The starter is a yeast/lactobacillus culture. Since these microbes are everywhere around us, it does not take any effort to make […]
How to compile the dc42 branch of RepRapFirmware for the DuetWifi. This process has been tested with 1.16 but should work down to firmware version 1.10
Just got an LCD TV screen from a friend for repair. It had beed sent for repair earlier, came back fixed and then broke again within days. The screen is a Toshiba 40L1333B, which was produced after 2012.
In the dc42 fork of the reprap firmware, there is a 5 point bed levelling routine for traditional cartesian printers. However, my bed is relatively big and warped in weird ways. I needed more points to level the bed properly. I made the following changes to version 1.13 of David Crocker’s firmware to allow 9-point bed levelling, where the 9 points are arranged like this:
I use a 5mm brushed aluminium bed (not anodised), equipped with a silicon heater glued to the bottom. So far I print PLA using glue stick and PETG directly onto the clean aluminium bed. Below some printing temperatures that I found to work well with certain brands of filament. RS Pro PETG white: 235C, 95C […]
